- THIS RACE WAS A BATTLE BETWEEN JEFF DERNEHL AND BOB MAYER.BOB IN HIS STO C5R 600HP CORVETTE.JEFF IN HIS GT-3 RX-7 IN GT-2 TRIM 13B P-PORT MAZDA.JEFF WAS ON POLE WITH A 1:28.139 UNDER THE TRACK RECORD!BOB AND JEFF DROVE A GREAT RACE !!
This is amazing. That vette clearly makes huge power.
But the sound from the rotor.....
When it sounds like that everything else is irrelevant.
I used to race a NA 20b peripheral port. Nothing on 4 or 2 wheels makes a better sound. Nothing.
Brenten Werner bad driver
Nothing makes a better sound ? Ever heard of a Ferrari Enzo, Ferrari F355 V10 Carrera Lexus LFA ? Compared to these that sounds like a mosquito attempting to make a landing for a quick sip in your ear.
@@msengineeringdavid3702 Subjective... to me a 20b sounds better than all the cars you listed. Now, had you mentioned a Judd V8... OK.
the vette has more power but the rx7 goes faster in the turns; could be the driver also
You were definitely faster through the corners.
I like how that Porsche was just durdling along like he was on a Sunday drive to church or something.
Imagine the face of the guy in the Miata when he had this two monsters behind and had to move out of the way hahaha
Oscar Lopez probs was routine for his brother
10:31 look at the track officials HAHA!
lol
if only this was a 4 rotor i would be completely deaf right now
Hahaha my thoughts exactly.... if in doubt or down and out get another rota out haha
Well even a 20b turbo would have smashed that vet
If he had a 4 rotor he couldve beaten the corvette easy!!!
@@violaconcerto123 he could have beaten him with this same setup but his trans fucked him up, the vette would have been left behind in the curves, without enough gap to catch him in the straights
vette was fucking fast in the straights tho don't get me wrong
427 cubic inches vs. 80 cubic inches. And yes, that thing sounds sweet! Seems pretty high pitched for turbocharged 13B -- more like a non-turbo 26B on a diet.
My low-to-mid 300 bhp FD would feel like turtle to the GT-3 RX7 driver.
You can’t really compare cubic inches. It’s like comparing a 2 stroke 1000cc to a 4 stroke 1000cc.
One of the coolest vids i have seen on UA-cam wow actually watched the whole thing good race
Just watched it too!

Could that be because the Mazda Rotary in racing form sounds just like the dirt bike that you are sitting on?
The old professor
1.3l vs 6.0l, rotaries are hands down a beast on the track
Yeah, weight has absolutely nothing to do with performance...
@@kennydemartini2169 I mean the C5r only weighs 1200 kilos so yes it does but the rx7 isn't gonna weigh a whole lot less
1.3 lol every rotary lover knows there a 3.9 litre two cylinder,how you ask well each rotor fire's 3 time's per revolution see it equals 3.9 litres 👍
@@poppa5289 actually the rotary is commonly considered a 2.0-2.6L, 110% not a 3.9L. It does fire three times per rotation but that is still only 1.3L of displacement. At most you double the displacement because its a 2 stroke engine only needing one rotation to complete its power cycle, unlike a four stroke which needs two rotations. There are also reasons to do with efficiencies which makes doubling its capacity unfair as well, so you'll never see it being compared to anything above 2.6L, its power output is generally closer compared to a 2.0L. Also even if hypothetically this was a 3.9L that's still 2.1L's down on the v8, so that makes reality of rotaries even more impressive
@@poppa5289
Nope. Doesn't work that way.
The sound of this 13B is just brutal! :D
ShinichiHatsune123
LITERALLY !!
riiiight at the end that clutch kick and limiter hitting fucking love it! 10:31
Right at 8:18 I was like "good move! Good move!" And then that corvette just pops up again! What a great battle. Props to you sir!
+autoparts321 Autoparts321 pretty much hit the nail on the head. The heavier Corvette has high entry speed, great braking, but lower speed at the apex and Corvettes have low exit speeds because they are horrible at getting the power down while turning. So if you're tucked in behind the Corvette, he is forcing you to race his slow style through the corners and then when it straightens out, he just walks away because of the hp difference. Follow him into a corner at a higher speed than what he is travelling, close the gap to the apex and get on the throttle at the apex, run wide and you'll squirt right around him. Then slide over in front of him and shut him out before he has a chance to get his throttle all of the way open.

Or you might die when the Vett nudges you from momentum and you roll about 12 times.
The old professor
@@clanrobertson7200 that's a risk i'm willing to take ; )
Or just put more power to the ground and accelarate by him at corner exit.
Thats exactly what I wouldve done downshifted to get better balance and power available to squirt right around him jumped in front of him and even if he opened the throttle as long as you stay in front you can get him in the next corner with higher speed.!!!
God I love race cars.......all of them.
I come back to this video every now and again. Just the best soundtrack
Time to add a rotor! Haha, love the RX7.
Fantastic racing there Bob and your self Jeff.. I thoroughly enjoyed every second, i was on the edge of my seat all the way with a ear to ear grin whilst i was ghost changing gears in my lounge chair !..This vid is the reason why I'm in love with my Rx3 and a old school NA bridgey ... Thank you Jeff for the vid...
Man, that was a great race!! Made us Mazda guys proud!!
I have this playing in the background as I'm doing engineering homework! Great motivation XD
2:01 I know that vette saw that burst of flames and decided it was all or nothing this day one of the absolute best races on UA-cam I hope to find you one day sir you have set a bar I hope to pass someday
love that rev match damn it.
blip that responsive throttle
sounds like a sequential transmission to me. its so fast between gears
I like how the man who was actually racing with the vette and uploaded this video with the captions is more mature than those commenting. I'm a big fan of both cars, but that peripheral ported rx7 just sounds wayyy too good to not be my favorite.
Man, good race. Reminds me on how heated my best friend and I get when we're on the road at the same time
This is hands down my favorite rotary related video on UA-cam. Thank you
Wooooo!!! Had me on the edge!!! Love the sound of both engines! I have a vintage celica and I'm thinking to swap in a motor! Either a throaty sound of V8 with itb's, or a snappy happy rotary (12a or 13b) to save some weight! My 22R is fun, but It's nothing compared to the powerful rotary or the brutal torque of a V8! BTW...the rotary sounds awesome!!!! X^}
Great driving by both of you and awesome sounding car. That had to be a thrill. Always a fun drive when you are matched up equally with someone
Music to my ears! And some damn fine driving on both parts!
Wow awesome battle, love the sound of that 13b. Too bad my rx8 doesn't sound that insane (although it still sounds pretty damn good). Way to keep the rotary alive in racing and show it's great capabilities on the track.
Great Job Mr. Corvette-Hunter...rotary Rules yes!. You make my Day...what a wonderful Rotary-Sound.
Greetings from Germany
Jens
i have never gotten zoo excited watching a you tube video!
Hell of a drive from the Corvette, incredible defensive positioning and still kept it flat out in some of those corners.
GOD I MISS MY FC, I'm working on a plan to get another, it's been just about 3 years since I last had a rotary, and I miss my heart. No contest, still my favorite engine ever made. That last lap made my heart race, you made my day. Amazing video, long live the rotary.
I feel like the 'Vette should have been flagged for blocking a few times. That RX7 had its number - nicely done.
Beautiful sound, great race. The sound is so delicious I just keep UA-cam minimized while working. Keeps my revs up.
I rewatch this video often. The sounds are so good
damn was hanging on to my seat hoping you would get him!!
That was awsome! I can't wait to get at that level one day.
Dam 372 hp VS 600 hp..........thats Really, Really, ......................REALLY GOOD imagine is was a Quad Rotor
imagine if it was a sequential turbo quad rotor.
I want this video played at my funeral.
i thought i was the only one
I’m a vette guy, but I was rooting for you! That was freaking awesome!!!! Best you tube video! 👍🏻👍🏻👍🏻
Great driving all around , there are several areas where we could see you had him . That said your car corners better and you handle it great . Love the sound and seeing it move . Good luck ,
20 years back I oversaw, crew chief'd 2 GT3 RX7's. The one I nicknamed 'Scrappy' because it refused to be beat over the course of 3 seasons won 27 of 31 races!!! With little more than a very radical 'street port' motor, the top end charge was unreal. In mixed class races, outran 5 liter Mustang's, Camaro's, Porsche's, M3's, V6 Nissan Z cars. Still have a mild port 12A waiting for a special project car.
Great driving! You were going in and out of the corners at much higher speeds than the Vette but he just has too much power for you to stay ahead in the straights. If you had like 50 more hp you would probably take him.
Man it was hard not to cheer and yell for the 7 at work... the sounds were absolutely orgasmic, and damn the driving was well fantastic job, wish I'd seen this sooner!
that brap, then the scream. uh best engine.
I used to love Vettes. A 600 bhp Corvette racecar barely walking on a two rotor RX7 is embarrassing. I now own an RX8 :)
But RX8's are (no offense) the worst rotary Mazda made. I have a FC, a friend has an FD, another friend has a FB, and an acquaintance has a RX8. Even with just a full exhaust system, headers and intake manifold (no ports or anything), the FB can still outrun the RX8. They're nicer, more modern cars, but they're not the best rotary.
stock to stock, the renesis still makes more power NA than those...but peripheral port makes more power modified. would you rather a better chassis, or more power?
no offence taken. I just got my RX8 last month. I obviously took the better chassis, Recaro seats, and slick 6 speed over the C5's V8.
I'm already thinking of ways to make more power, although 300 bhp is my ideal in the RX8.
Honestly if you plan to daily it, 300bhp is all you really need. If you want to take it out at night and have a bit of fun, maybe a little bit more. The biggest problem with rotaries is that to get a lot of power out of NA rotaries, there's only so much you can do (and most of it is pretty expensive).
Ultimately you just want to get as much air and fuel into the engine as you can to get more power out of these cars. I don't know if RX8's have rev limiters, but I know everything up to FD's didn't have a rev limiter.
Small things you could do to get a little bit more power to play with would just be the basics: air intake, better spark plugs (try NGK platinum's if you're not already rocking them). Porting is the most effective way to see a bigger power output if that's what you want, but that's where it starts to get expensive. But porting and bigger fuel injectors is what you would want. Unfortunately even with porting a NA, you're not going to see as much power as if you ported a boosted rotary.
I know you said 300bhp is ideal for you, but you never know what you might want to expand on :) Honestly all I would suggest for a daily (I'm assuming that's what it is) would just be a little bit of a suspension setup.
Ratchet L. Can conquer I love my rx7sa love the 8 but all that added weight keeps it equal to a stock 12a fb power to weight but I can't argue a wide body rx8 is one mean looking car and with a free flowing exhuast their shoot flames like the series 1 rx7s did but I just say the new Miata coupe style and it's almost identical in shape and size of a fb that with the 13b ren or any rotary would be amazing to see
Wow great racing to both drivers the V8 had just enough on the top end to hold off the Mazda. Excellent racing, thanks for posting enjoyed it very much!! Cheers...
The Vette is fast on the straights but its heavy. Rx7 reels him in on the twisty bits with late braking. I just love watching racing between engines with such huge displacement difference. I love V8 but I love Rotary more.
That was a great video.Ive owned an RX-7 and a couple vettes,I cheered for both cars.post more,,,
Probably the best sounding car ive ever heard
Well, you don't have to beat him for that Vette to know he's in trouble. Excellent driving, and excellent representation on what rotartys can do!
I think this is my favorite youtube video ever!!
That shit looks like hella fun even with traffic getting in the way. An the sound of that thing is fringing AMAAZZZIINNNGGG!!!!!!
great driving, your rx7 sounds awesome, wish my fc sounded like that
Good clean / safe racing. Well done! The Vette guy wasn't giving it away either.
The corvette has the torque and power on the straights, but the rx7's cornering is just phenomenal!
The rpms they are.......OVER 9000
ahaha
Over 9000? That's impossible!
Corey Worthington @ nope,its when pp's start to work up high rpm
@@jazpanoz4996 clearly didn't get the dbz ref.
Corey Worthington @ nothings impossible,lolz!
One of my favorite track videos of all time!
im a bit confused at how 6 people gave a thumbs down...The sound alone is worth all thumbs.
600hp Corvette VS 300hp Rx-7........ and the corvette couldn't get away. Why I love Rotary's ;)
Some great racing. You’re both damn good drivers.
My ears are bleeding and i loved every second of it :D
Bro this gangster was tailing the whole race then pulls a hearty skid at the end what a fucking legend
@jacekpace1
No, the C6.R works car has a huge fan in the rear bumper. It's a C6 by the tail end, but something self made. Nothing by Pratt&Miller, neither a C5-R nor a C6.R
beautiful Sound
Great vid! Love the symphony of transmission whine and engine noise. I have recorded the audio using flotv and now have it on my ipod. Thank you
you need an extra rotor , thats it
Amazing racing, you could tell how hungry you were to pull ahead.
Wow. Great driving on both parties. That 7 sure was filling up his rear view in the corners.
I have to give it to both of you! You both drive far better then I do but then again I don't have a full blown race car!
I can listen to this car all day.
This Vette is sure fast, but corners is the place where a lightweight rotary gains.
was gonna go large street port but after hearing this I might go pp instead, awsome
bla
good luck at stop lights
Just set the idle to 2200 lmao
Awesome drive. Strongest 13bPP I have seen since the old Imsa days. Most in SCCA seem to have gone with the 3 rotor now in the higher GT classes.
All that RX-7 needs is a ram air. Big ass 4- 5-inch sealed off to its actual intake with a filter in it and that would be the extra 30 40 horsepower in The Straits that it needs.
Music to my ears, PP rotary motor sounds amazing
Wow a HUGE Chevy engine/Rare race car over 100grand vs a 1.3 liter/76 cubic inch displacement modified RX-7
That's a standard rotary as that's how the first rotary was designed, look it up. Japanese got rid of the PP housings for side induction to make the car more usable.
noooo damn you gearbox!!! damn yooouuuu!!!! lol
even after gear box malfunction you still had him a few times!! man i love how this thing sounds when you downshit!! nice heal toe bro... nice!!!
#88 fc owner!!
That was really good battling.. Five minutes in even I was like, where can he gain ground on him before the back stretch. Lol
awesome car,awesome sound,awesome track,,nice videos
That.... is one beautiful sounding RX7 :) Much wantage of that engine for my own!!
Nice race one hell of a rx7!
great race rotary brother... Your driving is great! love seeing ya entering the corner faster then the corvette :D
Fantastic race. Great driving on both parties part. Slightly sad the rotary didn't take it, but great race. A few of those attempted overtakes looked good, then BAM corvette pulled up by a nose. He had a great brake setup to pull some of that shit off
I always liked the rotary engine sound. Good race man. Congratulations!
That's a great vid! Only thing that could have make it better was shots from the Corvette looking back, man you were all over his ass. Great racing action from both.
Great race action!!! ROTA POWA!!!
Great vid!, and congrats on a wicked car! My future plans include a large ported rotary race car. I have already done the stock rotary race car.
excellent driving! Thought you had him when you snuck by on the left as you both came up on those 2 slower cars...very fun to watch!
The corvette V8 guy be like: THOUGHT I HAD HIM THERE. MAN THAT DAMN DORITO STILL KEEP UP
Very entertaining, great racing! Thanks.
Awesome vid dude inspires me to make a track car
GREAT race!!
Man.. the abrupt ending was like pulling out right before finishing the job.
Great video great battle looks like fun!
That was a great race. I want more vids like that!
I can't imagine how frustrating it is to reel someone in in the corners and then watch them fly away in the straights lol.
Wow, amazing sound from this 13B. Love it.
Could you please upload some more. :)
Yeah I know what you mean, but he is in a 1st gen making probably 300whp (+/- ~20whp). A race prepped 1st gen weighs no more than the hair on your head ^-^
But yeah that really amazed me how well he kept up, I know the vette is "race prepped" as well but still doesn't come close to the weight of the FB. But still, shouldn't be able to keep up doing more than 200 km/h haha. Just goes to show how a well balanced chassis is always the 1st choice when racing.
Damn I love that sound
You would think a race would have cars in the same horsepower level. That Vette seemed like it had at least 50 to 100 HP than the Mazda.
What an awesome video, great driving!
Like a chihuahua on steroids in a tiger's cage,
but he definitely held his own, much respect.
