Yeah but how long and how hard can you drive it!! Truck might only last 1 hot hours getting really worked in the field
But will it be reliable?
@@l0I0I0I0 reliable for just driving around 40 mph waving at people’s!
I would love to see a 5000hp 12 cylinder rotary engine! The applications could be endless!
Perhaps I would make a good reliable portable generator? Except bad gas mileage?
The car industry has had so many shocks that it's now on life support😂
According to Scotty the only use for EV vehicles is to shock the industry back to life.
I don’t know who’s doing the editing for Scotty…
😅 ain't that the truth..
I'd like to see the Wankel motor actually work for us again. I believe it's an awesome design. & so unique, It's got to work! 😊
So many shocks, cars industry will get bouncy! Hahah!
Mazda did say one time that they would never give up on the Rotary as long as the company existed even if there was no publicly available version of it, that they would always keep working on it internally.
I'd love to see them go for a public version again.
It's time
They are obsessed and stated they will burn money forever because they believe it's the perfect design just not yet perfected. I love it
Just like the Japanese and the boxer engine. Accept I hate the boxer engine and hate more doing head gaskets requiring a machinists plane on a boxer engine with a high likely good of immediately failing.
Me too. Mazda has invested enormous effort and brainpower on rotary engine development. Good on them for keeping a flame burning for Wankel’s invention when everyone else gave up.
@@bradnail99 This is a money pit that will never be produced due to inefficiency and
emissions.
@@icosthop9998 Mazda will never go out of business in our lifetime. They sell a lot of product.
There is so much incorrect information in this video that it's not even feasible to correct it. Just safer to consider everything in the video wrong and proceed from that assumption.
I had to scroll WAAAY to far to find this!
wdym?
@@UA-camrMomentsYT ALL HAIL AARON CAKE! (thats what she said)
Scotty gives all kinds of bad info i work on cars for a living and cant stand his channel
Scotty doesn’t know anything about wankel rotaries
I love how Scotty included Liquid Piston in this without actually saying anything about them. Their Peanut in a Triangle design solves a lot of the problems that the Wankles have. I am the former owner of a beautiful Gen 2.
Because it is exactly the same design as the Mazda just inside out , the Mazda has a 8 shaped chamber and a triangle inside , the liquid piston has a triangle shaped chamber with a 8 shaped rotor ! Just the same thing inside out !
I currently own a 93 twin turbo RX7 and a 88 turbo RX7 BOTH RUN ha!. IMO i feel Mazda REALLY puts in the time and R&D into making great cars I'm looking forward to seeing what they will do. The Rotary community is HUGE and with the growth of technology these engines just keep getting better and better!
HAHA I own a 93 twin turbo and 88 as well... neither of them run, but thats due to my neglect more than anything. And the reason they don't run has nothing to do with the engines going out. My 93 is in the process of getting resurrected by Banzai Racing right now.
I miss my 88 Turbo II. That car was fun to drive and handled like it was on rails.
@@maximusextreme3725 FC's are the best!
@@karlwithak. they were just so simple! I’ve never had one leave me on the side of the road!
@@karlwithak.
???????????????????
Great vid! I've always thought the idea of a rotary engine was super cool. Ever since being a teenager I have been fascinated by this motor that is piston-less and non-traditional. I hope Mazda can make it happen. While the rotary engine may be "dirty" it has so much potential to create HP in such a small package. Thanks for the info!
*Doesn't matter how cool it is, EV's are far more efficient, it's not even close, you can buy roof top solar for your house to charge your car on the weekend and it's free to run, far less maintenance, just all round better way to move the car.*
So….. build better catalytic converters, or something. Fix the emissions issue, and get the ball rolling, again!
@@robertjdm3988 the seals make the rotary an inherently bad design. It's cool asf but...
Driving a manual RX7 is like driving a fast airplane. I love their power and high RPM.
A damn shame you can’t find a good condition, original unrestored RX-7 FD for anything less than a million dollars or so these days.
@@stoneylonesome4062 yup. I had a white 81 and then a red 84 with black leather back in the day loved those cars and wish I kept mine..
Nothing compares to the smoothness and power delivery of the Rotary
I had a Rx3, 79 Rx7 and a 85, 85 first fuel injected car I owned they all were nice cars but I'm glad that I worked at a Mazda dealership.
@@stoneylonesome4062There are plenty of them on Bring a Trailer each month, well under 100K. But you don't seem to do any research before you make a statement.
Scotty, where did you get your info?
This video is SO full of mistakes, it's almost laughable....
I had and RX-3 and an RX-4 and loved driving these rotary engine cars. There’s no doubt the rotary has issues that need fixing, but the power, smoothness, quietness and lightness are great to live with.
Had a 1984 GSL-SE, smoothest car I have ever driven, the only thing smoother would be an EV.
@@RickHolland1968 straight 6 are very smooth. And a bootful more torque, the only thing the rotary has over it are the revs it can go to (not everyones cup of tea tho) and the lower weight. I think I would take a Nissan RB engine over a rotary.
I had a 1973 Mazda rx3 with a rotary that thing would backfire after it sat turned off for a couple of minutes scared the crap out of people 😆
Just for reference the 12 rotor was unveiled by Tyson in 2015 and given to Rob Dahm in 2023 the motor has been reconstructed with some much needed machining and is getting upgrades that may actually achieve the 5000 HP goal
Why would anyone need a 5000 HP engine? It reminds me of idiots in Los Angeles,sitting in bumper to bumper traffic for hours.....in a Lamborghini.😆😆😆🤔
@@MichaelKurse since the 12 rotor was build for boat racing, i guess people doing boat racing need small engines with 5000 HP...and it's a prototype, it was never meant to be mass produced. Oh, and those "idiots" have a Lambo, what's the problem with sticking in traffic with a Lambo? I would like to get stuck in traffic with a Lambo...better than sticking in traffic with a peasants car 😁
@@MichaelKursebecause they want 5000hp? Becasue they know how to handle 5000hp? Becasue they can afford to have a 5000hp build? Because they race, like the commenter before me said? 😢😢😢 😂
I am interested in seeing rotary engine innovation especially with hybrid vehicles. Seems like a perfect matchup. Unlike the high power applications which do not highlight the rotary benefits. Absolutely love your presentation of this complex material! Thank You Scotty!
Debatable., the most comparable vehicles is between the Rav4 hybrid and the CX30. the Rav4 has about 40 mpg while the CX30 rotary extender gets like 30 mpg at best. That moving combustion chamber is just a serious obstacle against complete combustion.
A perfect matchup? An engine that only benefitted a handful of enthusiasts? An engine that needs constant maintenance to be reliable? An engine that is renouned for poor emissions and fuel economy? Bring it back in an enthusiast sport car not a bloomin hybrid!
This video said that the vehicles with longer lifespans stayed mostly on the highway. Sounds like something that would work well for constant charging if they could solve the heat issue in the batteries....
the only thing hybrid gives the rotory is toerque and it being instant is a benefit but if mazda made a production 20b it would beat most modern sports cars if it had an electric motor with it
Looks like you were using some animations from Liquid Piston in this video. Very different from the Wankel - almost like and inside-out Wankel. Look em up - pretty cool outfit. A UA-camr …warped engineering I think? Made a clear head so you can see the Liquid Piston engine work. Pretty near!
In years past Mazda has said that one of the biggest problems was to get the apex seals to work over a wide rpm range. Making the engine into a range extender makes perfect sense as you can optimize the seals to work at the recharge speed. The rotary engine has always been simpler and smaller than the Otto cycle.
You really need a massive battery range advantage because even as a range extender, it is still like 25% worse thermal efficiency.
@@Appletank8its nowhere near a 25% efficiency gap when both are run atva static rpm like they would as a generator in a range extender. the efficiency can be brought well within range of modern piston engines in that setting, and its extreme performance relative to size would take up less room and allow for more flexible instalation and better balance of aerodynamics and cargo room
all engines will benefit from running at a set speed if they are properly designed for it, but reciprocating gas engines have the least to gain from it. diesel and rotarys will gain a lot more. diesel will have all the same drawbacks of gas piston engines with the addition of about twice the weight.
is a rotary a good choice for something like a pure gas commuter? no
is it a nearly ideal choice for a range extender for the average consumer who will only ever need it a couple times a year? most definitely
@@silentbobfan32 From the couple of research papers on Wankel efficiency I've read, yes being on the ideal BSFC zone is much better than being off it, but the peak isn't as high as you'd think.
Even in a world with perfect seals, the Wankel still has the problem that its combustion chamber is long and thin, resulting in high heat losses to the coolant instead of mechanical work, resulting in a theoretical max *~30%* efficiency. You pretty much need a magical material with 0 heat transfer to come close to piston engine efficiency (~35%).
Engines in the RX8 were hitting 25% at _best._ When Toyota is hitting 41% efficiency with their Dynamic Force engines, this means being 25% worse on fuel-to-power right off the bat.
This is partly why a lot of engines nowadays are about 0.5L per cylinder, its the best combo of surface area/volume and packaging.
If Mazda really wants to sell the idea of a rotary generator, they have to push the other advantages as hard as they can, because fuel efficiency ain't it.
The theoretical ideal for a PHEV is a big electric range with a small, lightweight engine to boost overall range to do long trips comfortably. The small Wankel seems like it could be a perfect fit. The problem is that the addition of the small Wankel cuts the electric range of the MX30 in half, to the point it's basically on par with the RAV4 Prime on electric range, and much worse on gas range. What little information Mazda has given out has implied an MPG of 25. Out of an engine producing only 74 HP.
This is awful.
Thank you, Scotty. You've helped me save thousands on repairs and extend the life of my cars exponentially.
Unfortunately not all auto techs are like Mr Kilmer.. honest..
Quick point of correction as per knowledge gleaned from Rob Dahm's video "Fixing the BIGGEST Problems of the Rotary Engine" : one of the issues of rotary engines is that to boost adoption, they routed the oil pan's oil to a port to lubricate the apex seals, except synthetic oil doesn't burn cleanly. To remedy this, the port can be plugged at the expense of making a premix of gas and 2-stroke oil that's meant to burn much more cleanly. The oil pan's oil stays in the oil pan and is used to lubricate the rest of the engine with whatever oil you want.
Better than an EV that's for sure.
???
@@carlosandleonhe said "Better than an EV that's for sure."
I loved the Mazda rotary engine, I bought a new RX7 and it was a fun car to drive. I always noticed at higher speeds 80+ the engine sound was like a sewing machine it was so quiet. And no vibration at all. I really hope they bring back the rotary in a twin or triple rotor, that would be AWESOME !!
Listen to electric motor at 15,000 rpm and 0 vibration...
@@firstbigbarneyew
The rotary engine is legendary.
Scotty can let more than a few days go by without XYZ "Shocks the Entire Car Industry"
It is interesting to see that you include pictures of the Liquid Piston rotary engine. That's a different company.
I know, range extenders aren't cool, but the rotary could run at a fixed speed and load (when needed) and that would minimize a lot of technical problems.
EVs are impractical from issues of battery size and recharge time. This might make a practical compromise.
Charging and battery tech gets exponentially better over time
@@michaelpapazis It gets gradually better, but not exponentially (and the current batteries, by the manufacturer's own specs shorten their life by frequent fast charging). The big issue currently is heat. The electrolyte in current battery designs is contained withing semi permeable membranes and simply pumping more energy into the charge heats the electrolyte far faster than it can flow. And that is bad. Even now, auto batteries have complex circuitry that turns off different cells that are getting too hot
Faster charging will require a completely new approach. There are theoretical approaches, but none ready for mass adoption in the near future.
My butterscotch colored rx3 only takes 4 hours to overhaul. New tip seals oil pump rebuild included. I have over 800,000 miles on it with one modification, a webber side draft carburetor. It runs great has enough power and cost of ownership over the past 40+ years is next to nothing. Keep your car fix what the factory didn’t and enjoy.
I owned 2 RX-7s. I'll never again own a rotary engine. I had 4 episodes when I couldn't get the thing started and had to have it towed to the dealer to start it. Once it misses that initial start attempt, they are done. The 1 time I did get it to start was when I put it on a battery charger and got it to start after cranking it for 10 minutes on and off. That warmed up the engine.
23 y/o in 1929: I will create an engine.
33 y/o today: i am offended because you misinterpreted the 7th of my genders.
Would love to see the rotary make a comeback. Love the RX7.
I had only once a chance to hear it live. I got shivers all over me. Its so amazing. Shame they are so rare in south europe.
If nobody has come up with a more robust, much more efficient, and much longer lasting apex seal, Mazda can forget it. Nobody, with any sense, is going to pay that kind of money for a vehicle that probably won't make it to 150,000 miles, except, maybe, rich, adventurous people.
I've always loved my rotaries. And most people that have used them will tell you the same. There's just something about them. Thanks for this great video!
In basic terms ; the Rotary suffers the three problems Two Stroke Engines suffer from and why you rarely see Two Stroke Cars or Motorcycles on the Highway these days. Unacceptable Fuel Consumption , Excessive Pollution and Short Engine Life....
Rx7 has always been one of my favorite cars, I'm ot mechanically inclined or a speed demon, I just thought it looked gorgeous! I've heard of some short comings before but this definitely gave me some perspective and I've reco sidered my stance on it being my daily driver!
My RX7 was a daily driver the 12A Rotary was rock solid back then. But I heard the 13B rotary and turbo's were problematic..
Please!! The Big Three Legacy car makers can't endure a Single shock any more.... Electric cars Going to bankrupt them! And now this news... Ow man😂😂😂😂
Speaking as the Car Industry, I was not shocked.
Yeah baby, big polution, big unburt fuel, big fun. Brapbrapbrap Big rebuild, no certified mechanics. Doing it at home, 80k miles yeah baby rebuild yeah baby.😂
I'm glad Mazda isn't *completely* turning towards the muted luxury direction most car manufacturers are going. There's still the innovative spirit and automotive passion somewhere in there, and I love to see it!
While I appreciate the support given to the rotary, there are SO MANY things wrong in the text and graphics of this video that I don’t know where to start!
If you want more info on the 12 rotor boat engine, search for Rob Dahm’s channel.
Oh, and that beauty of a red car teased during the speculation about the return of a Mazda rotary sports car? …that’s the RX VISION prototype from almost a DECADE ago.
Im grateful my uncle taught me how to work on these motors growing up. Family has had Rx7's left and right. It was fun working on these. You can take everything apart and rebuild in a day of you know what your doing.
Felix Wankel began working at German firm NSU Motorenwerke to develop a rotary internal combustion engine . His name is pronounce with a V "Vankel" and not with a W, Remember its German and not American English or English.
Uhh, that was one of the most concise, informative videos I’ve ever seen. Nicely done.
Wankel rotary engines are probably best for torpedoes. Small, cheap, lightweight, powerful, and don't last long.
It seems like every single day one of the car companies is shocking the whole industry. I'm shocked when a day goes by when there isn't a shocking announcement. 😀 😄
Wanted lightweight, efficient, cheap, and easy to repair.
It's definitely lightweight.
1/4 ain't bad i guess.
Give Liquid Pison some credit for their oval rotor in a three lobed chamber
The 12 rotar engine is not new, this thing was built many years ago for boat racing and never really became what the designer hoped it would.
Talking about optimizing rotary size for mass production just highlights that you have no idea what this thing is. One of your script writers probably just saw it given to UA-cam's favorite rotary head recently like everyone else. It'll be a long time before it actually runs in anything meaningful, if ever. The same creator who gets every headline as if he's the Elvis of 4-rotars while he copies and takes credit for other people's work.
Scotty, what about running the rotary on CNG ?
I've followed the Wankel from the beginning. Nothing will ever address its fatal flaw which is surface to volume ratio of the combustion chamber. Wankels simply lose too much combustion heat to the cooling system. That's it. Game over.
I always thought that it's just fundamentally difficult to get a good seal with the rotor geometry. Would an additional spark plug located later in the power stroke help even out the combustion imballance?
Rotary engine cars are really, really great...except for all the things about rotaries that are really, really disastrous. So yeah...no.
Loved my 1st and 2nd gen RX7s, never had an issue with oil burning. I drove mine in the city and had one that I sold with over 200k miles and still ran great.
I used to work on Mazda rotary engines in the 70's they were brilliant, BUT, they were let down by the rotor tips and side seals used to fail. 🏴
I had a rx3 and rx4 back in the day love them because the y where different from regular engines. I love for bring the rotary engines back.🙂
I see a lot of RX-8 sitting around with bad engines..... Only one I've seen lately that works good ..has a LS swap
I have had a RX2 & RX3, they were the most fun I have ever had in a car, I swear I raced the RX3 daily, lasted for 2 years, then I sold it, because it scared the crap out of me, it developed a weird gyration in a corner at about 135, it almost sent me into a apple orcherd, I had to straighten out in the middle of the corner, and reset the drift in the corner, made it, and put it up for sale the next day....looking back I wish I would have kept it :)
Rotary engines are reliable if you look after them, majority of people don't. The engine fires every stroke, its an engine for sports cars, not everyday driving. Personally i blame buyers for not knowing what they are buying
Oh and they run great on hydrogen and unlike petrol don't wash out the oil.
Rotary engines and cool, and different, which kinda makes them interesting and unique, but I definitely like the reliability and longevity of Mazdas piston engines. I loved the BP engines that were used in the Miatas. The old BP engine from the 90s in my car is still running in 2023 and still doesn't burn any oil. I know there is a cult following for the rotary, and it would be cool to see them return with improvements.
You displayed the liquid piston engine not the wankel !!!! Credibility issues here !!!!
I had an RX-3. I found that the mpg I got at the then-mandatory 55 mph was less than what I got at 70. It was the smoothest-running engine I've ever had with the obvious exception of a electric motor. If they bring out another, if I can afford it, I'll buy it.
I had an rx4 back in 75. It never burned oil. I worked at a gas station and changed the oil frequently. It could spin the tires. That little engine had power and people couldn't believe what it could do.
@@billrehm3590 They are all made to burn oil. If your oil metering pump is working correctly it would use a quart per 1000 to 1500 miles.
Here’s a business idea ! Load up a van with a huge diesel generator, and make a mobile charging business for electric vehicles… 😂
Always interested in rotary engine developments. It is true that fuel consumption was 20-25% higher in 87 RX-7 compared to 84 Honda Accord driven over the same route.
Mazda has proven to be stubborn and continues with the rotary. There is a great opportunity here and I hope Mazda is successful.
N/A Rotary durability is better than turbocharged ones.
Buttheads often blow seals by brainless dialing up the boost.
It is a racing oriented engine that Mazda should have never advertised it as a passenger car. You are recommended to redline the rotary engine at least once per drive to burn away excess carbon deposits.
Thank you for all you do Scotty 👏 👏 👏
"A redline per day keeps the mechanic away"
Scotty, you are my favourite mechanic and have been of great help over the years but if I hear about one more engine that will amaze
auto indus. and the world I will fart out one of my kidneys on to the floor. Where are all of these fantasy mills that are the future of motoring dang nabbit. Ireland awaits.
Hopefully someday the Wankel engine will be long lasting engine, the amount of hp per displacement without any forced induction is quite amazing. The happy benefits of E85 no benzene, no toluene, no xylene. Much lower amounts of PM2.5, PM10, CO,HC, NOX emissions than gas and diesel.
The aircraft rotary and the vehicle rotary have ABSOLUTELY nothing to do with each other.
Truly, I humbly believe it is an amazing engine.
Rotary engines have more than had their day. Enough of this silliness. I wouldn't touch one with a barge pole. Be done with this whole idea.
Rob Dahm has that 12 rotor now. He is gonna work his magic with it......
Love the Rotary engine. Years ago I had a Mazda RX-2 with a tuned 13B Bridge Port, fuelled by twin 48mm Webber carby's. So much fun to drive. It definitely surprised a few expensive cars out on the road. Wish I still had it.
ditto. I really enjoyed pulling up along side the Caddies on I 5. They would never let me pass. That was until I bought an RX 2. Funny little junior reader car that left them in my dust.
I had a ‘73 RX-2 4 Dr sedan. Bought new still sitting on the lot in ‘74. Looked like a Toyota Corolla but surprised the hell out of some 396 Chevelles stoplight to stoplight. Of course, it got close to the same mileage as a Chevelle. 2 distributors with 3 sets of points. What a mess, but loved the way it ran. Had that boxy 4dr, terrible aerodynamics, up to 115 one night in calm air when it started getting squirrelly. Still had plenty of throttle left, but I backed out of it. Speedometer went to 135 mph and I think it could get close in an aerodynamically stable car. Limitless rpm’s.
fun fact: The rotary engine.. real name.... WANKEL engine. :)
A rotary motor makes more sense than an electric motored vehicle.
It will fail as a range extender, too, because it’s inherently less efficient than a piston engine. You’re never going to get around the fact that a piston engine will burn fuel more efficiently.
I hope Mazda does produce another Rotary Engine car. I will buy one! I’ve owned my 83 rx7 for 27 years! Driving a Rotary powered car is like nothing else it’s so fun. A ported and or turbo Rotary is just RAW power!
Scotty has swallowed the entire Mazda press pack and believes it to be true. Poor Scotty when he finds out that this was the last roll of the dice for Mazda as they have no EV strategy and are about to go bust
Has anyone seen the 12-rotor version that was just rebuilt on one of the YT channels? I don't know if they have fired it up yet or not. It is 3 banks of four rotors
yeah thats the 12 rotor that was in the video it's getting rebuilt by Rod Dahm theres stuff on his channel about it
Very bad video, a lot of information and images that change in a second of time as if it were a music video, so you can't follow the content normally. Moreover, the video should be aimed at the average audience, and this one seems to be made for engineers.
Be cool to see one in the MX5 Miata..
If everything shock the entire car industri is shocked by everything, is it really schocked?
Rotaries sing and sound like angels! Its a beautiful thing
Brap brap!
@walsakaluk4630 so do Subbies, lol. I own an 2004 STi and absolutely live the sound it makes!
Whyd he use a liquid piston engine for to explain how a mazda rotary works lol.
When it comes to driving anything with a rotary engine in it, u should use 2 cycle mix in ur gas tank to get longer times between each engine rebuild and I would love to get one of those new Mazda’s and tear the rotary out of it and put it in something else
Would have been a good car if you mixed the gas and oil like a two stroke and remove the motor-oil injection.
Yes, definitely excited to see a comeback. Been a fan of the rx7. I can't say the same for owning one though, I'll leave it to the bottomless pocket modders to do that. But it's exciting to see what people will do with this new rotary.
It's cheaper if you do the work yourself, only rich people own slave mechanics.
Over and over and over and over and over again we have been hearing about how solutions to the problems of the Wankel rotary engine have been found. And here we go again.
I had a Mazda RX-2 with a standard manual five speed. I got through the gas shortages during the seventies, but I wouldn’t be in one of those cars at my age. I was in my twenties, so at that time I didn’t think I was going to die 😂
They never came with a 5 speed, only a three speed automatic or 4 speed manual.
I wonder how the rotary engine would do well if it had natural gas or hydrogen fuel sounds interesting if they can be done thank you have a good day😎
Why not wood gas (spark ignition) or even a diesel cycle.
If it can burn it will work.
The RX7 was a nice car.
Diesel is the absolute best there is no negotiation longevity durability efficiency and lower maintenance so of course the system attacks it trying to destroy it
I have an 82 RX-7 with just over 70k miles. Runs like a champ. It’s a completely different feeling car to drive - I could drive all the way to work in third gear. In fact, on back roads, I almost never use fourth (and never fifth). Down shifting is a very different experience as well because it’s so smooth and happy at high RPMs. Super fun little car and I always loved the first gen style.
The bottom line is to get rid of smoke and pollution need something that does not generate pollution no matter what the gasoline engine is the efficiency can not be more than %40 that means pollution.
My first car was an RX7. It was so fun. Seemed to hug corners like it would never let go. Of the line I'd be in 1st while the other guy had already shifted to 3rd! Fun little treat to have had.
Of course I'd like to see it. But the problems are very hard to solve, especially the seals.
Thank you Scotty. I bought a 74 RX4 in 78 right out of high-school. Fun car. Ended up blowing the apex seals, my own fault and bought a core. Kept it going until the frame rusted. Then on to an 85 RX7. Fun car.
Sounds like a dead end technology to me.
Like the steam locomotive about a century ago.
A better range extender would be a turbocharged 1 liter diesel
Turbos are not happy running full tilt for long periods, which is what you would want a generator to do.
If you've owned one , you've definitely heard of the apex seal...
I have an RX7, yes I want to see the rotary come back! New and improved
Rotary engines are an excellent example of a neat idea in theory that does not pan out in reality. "The Devil is in the details."
Scotty, There is a reason you have almost 8 million subscribers. Such a well done video and I can see the amount of work you put into this. Very informative....When I was in High School in the late 70's my dad was a Mazda dealer and he allowed me to buy a 1972 RX 2 car and had his mechanic build me a supped up RX 4 engine (I don't understand how you could sup one up but it ran real good in that little RX2 body) The funny part is every time I tried to be real quiet coming in late on the weekend I would get all the way into the house and BOOOM!!!!! You guessed it a backfire that would always wake my dad up, it was like his own little alarm clock, that danged car would rat me out every time. Good memories thanks for explaining how this happened.
And you didnt mention rob dahm fixing and improving that 12 rotor custom engine a youtube self taught engineer is making that 12 rotor into something amazing
