I think “Wifey’s Whip” is a great name for the Eliminator! That way when you gap people out in Parker they know your wife’s boat is faster than their boat 🤣
@@stuwest5862 look deeper. The term "whip" actually refers to steering wheel "Whips" were originally used to steer stage coaches. When cars were invented they called the steering wheel a whip because it steered the car the same way as a whip steered a stage coach.

That innovation at the jet nozzle is genius. I work with pump systems and once I saw it I was like.. oh yeah that will work.

OMG! Finn, Dave and Cotton you guys are awesome! Jet boat content is the greatest. I’m 54 and grew up on jet boats! My dad was one of the first to have one on the river here south of Chicago in the 70’s. Once everybody saw what he had and how fast his 72 Sidewinder went with a big block 455, everybody wanted a jet boat! Within the next 2 years the majority of the guys were getting jet boats. My dad has been gone 20 years now but you are helping me bring back all the memories from then. Thanks for posting your jet boat content!
That HIP process was probably done where I work, we have seen Nascar cylinder heads, aluminum 9" center sections, and those grid fins on SpaceX rockets. Pretty cool process, VERY high pressures.
A quick tip for anyone out there that doesn't know for aluminum you don't need a metal chop saw you can literally use a regular wood chop saw with a quality wood blade and you can use a wood router on aluminum wether its pipe,tubing ,channel whatever ... Sounds crude and dangerous but it's not you will be surprised how quick and easy aluminum cuts with wood blades., I work at a large custom fab shop and we use these methods quite often, one thing always wear PPE like glasses face shield and don't skimp on hearing protection high speed tools are ear damagingly loud! One plus is a quality wood chop saw usually has very accurate miter adjustments compared to most metal chop saws especially budget abrasive saws. Fyi DO NOT use any high speed wood cutting equipment on aluminum that doesn't clamp the material i.e. table saw or circular saw, it would cut through the material no problem per SE but where a table saw can fetch up and send wood flying at super high speeds with aluminum binding is way more likely probably definite and metal or blades flying at bullet speeds it would be life threateningly hazardous .... Do not use a table or circular saws not even in a pinch!
Another great, educational video but...without sounding like an ass... jet units actually all started in New Zealand with a company called CWF Hamilton. Yes, I am a proud Kiwi 😎
The reducers look strange to me. I think it would look cleaner still and offer better performance to boot if you merged the cold side together into the final size before your pie-cut elbow.
There's a bottleneck where the two turbos merge before it opens up at the throttle body. I'd have liked to see the throttle body diameter run all the way to the Y.
@@terencecampbell8363 100% you're right, the Y into a larger elbow is not a particularly difficult joint to fabricate if you template it up first, it would fit, and give a good laminar flow.
Literally exactly what I just came to post :D It just looks nasty to me thinking of flow characteristics... massive restriction with the turbos fighting one another... it won't but could theoretically nearly halve the turbo performance
AAAAAH MIKE!!!!! @3:10 is that chuck key in the lathe chuck!!! Man you gotta get that thing out of there before someone accidentally turns that little lathe on and eats that chuck key for lunch!
great video! i realy like this solution and you guys did a great job showing hot to do it. but if you want a bit more flow you can also cut the y tube from the turbos a bit further back, make the round cut on the 90 ovalized and weld something like a 3.5 inch or even 4 inch 90 to it. right now the 2 turbos are pushing a lot of air trough that tight small 90 and that risistance will also make a lot of back presure resulting in a lot warmer exhaust temperature. cheers! cant wait to see this thing slapping cheeks in the water!agag
You guys should stop by little Rock arkanas and help me with my 69 firebird. I have to resize the drive shaft, install front end parts. Build a 428. lots of fun. 😁
Wow! You guys are so inspiring. I’m digging your new boat build. I’m working on an extremely low budget but I picked up my first ever jet boat project recently. It’s an old Carlson CV19 with a Ford 460 and a Berkeley pump. The engine has some cooling issues so I have some learning curves to work through. Just keep making great content and inspiring folks like me. I live on the south east side of the city on Jackson Lake. If you’re ever this way hit me up and I’ll treat you to some good BBQ (Georgia style).
I love pie cuts I've been using them for many years. I buy only straight aluminum tube now. That and my harbor horizontal frieght band saw I've had for 10 plus years. Next you should look into using vabnd clamps .
Nice work guys Chop saw made super clean cuts The Eliminator is beautiful Really like how tucked in everything is around the motor The new pump is super cool
From a Machinist, looks like you did everything right on that Bridgeport. With that 2 flute end mill on aluminum, you could up the RPM a little. Looking Good!
Your honesty and integrity and your teaching skills are appreciated greatly. Many are those on your tube who are there simply to entertain us and increase their view numbers, even if they are being idiots doing it. You all know who I speak of and I would be lying if I said I was not entertained by their stupidity, even though my comments degrade them. I am an old worn out fart who started out in automotive right out of hi school mainly because I could not afford any college, so I did what I could to support my wife and children, first one I had while still in hi school. I never missed a child support payment and left 3 x wives way better off than I was. Just a word to all you young men. Do not short change yourself, and put something away for your 'golden years' (my ass). Before you know it , your days of racing and toys will be way behind you an your body will be as worn out as a super t-10 with 5000 passes behind a well endowed big block. You will grind and clank and pop out of gear 20 times before you reach your front door most days. You will not believe what all your tools will fetch at yard sales or online. Invest in yourself NOW, Dont wait till you go down in flames on the big end before you hit the sand traps. Believe me , it hurts.
I've gotta say that I have been absolutely loving the latest season of Faster With Finnegan on MTOD, wish there were comments there but I really hope it's getting the love it deserves!
Finn, please in the next video talk about setting the pump back; why people do it, and if you know, how to do it on a boat not already set back! This video was great though thanks so much!
Your definatley going first class all the way ....the motor looks so badass with the turbos set up like that, Suuper Clean! The custum jett drive is sick as F**k too!
That trick nozzle is going to be like having a torque shifting prop. A buddy had one of those props on his Checkmate. It came out of the hole hard as hell and set you back in the seat when the prop switched. It was like being in a car with a Powerglide.
Every time I saw Game Over I thought of those retro video game Game Over screens. Using a similar theme I think this boat would be cool named 1UP. Maybe have a green mushroom on the back which would really pop with the red. And then when you're in front it's like the other "player" is chasing the 1UP mushroom
I used to be an Engineer for Nelson and I approve of the twin turbo race boat! My last Project was Mad Max. So much stainless! P.S. I am The US Scientist he ever so briefly speaks of! I worked for NASA as a Rocket Scientist/Astronaut at that time.
When you are working with aluminum angle or flat stock. Wood working tools will do the job so if you wanted to bevel or round over the milled edges on your windows in the angle you can use a small router and a bit with the profile of choice to make perfect uniform edges around the windows super fast and easy
In the 1950s Sir William Hamilton pioneered the first commercial waterjet. Fast forward 70 years and HamiltonJet remains a market leader of waterjets and vessel controls.
Learn as you go in machining. I went to college for machining. You’ll love it the more you do it. Most of the time you have to figure things out as your machining. If it works for you then do it. I would use a brush instead of air to remove chips from the work peace. That way you not finding chips all over your shop or garage. Just a tech tip to make clean up easier and faster on you. Oh feeds and spends are the key. Good luck.
Hamilton jet 770 multi stage is another brand father used them in the aluminum boats he built here in Alaska . Loves the boat vids as much as the the others keep up the awesome content.. your fan northernnomad...
I know its MUCH harder but id love to see the hot side of the turbo jacketed. I'm planning to build a 25 ft Eliminator Daytona with a BBC - haven't decided on the inches yet. it will be 540+ turboed. I want the motor cover to close so I want everything jacketed. These boats have the best radiator known to man! USE IT!
Perfect example of fine details and sticking to your ideas. People generally take the easy way out because finagling just takes too much time. As shown here the payoff is definitely worth it and unique.
Use your mag dial indicator base and pointer wire like you would use degreeing a cam to repeat your center on the cut-off saw when flipping the tube from side to side.
Dave ,you looked like you was really getting ready to mount that jet drive ! Some time you stand in compromising position without knowing .thanks for the laugh .:-)
Hey Finn, you don’t have to defend your decisions, it’s ur shit doesn’t matter what other people have to critique and give their “professional” opinions on.
Back in the day there was a guy that had a powerglide trans between the motor and jet. That was an amazing rig! I can’t wait to see someone duplicate that build!
I dont think it works like that. The boat would go faster at high rpm like the top of first or second and slower when it changed gears or have low rpm.
There’s no quality content on UA-cam that involves building a fast outboard engine and boat build. I’d love to see you tackle that subject. I bet it’d get more views than you think.
Looks good im curious though why you didnt go bigger diameter tubing on the 90? It seems like there was an opportunity to go straight to a larger diameter after the Y where the two turbos pipes meet?
Its a family boat it'll still be plenty fast with the minor power loss there and 1 thing everyone should know by now he'll keep tinkering and changing things after testing till he's happy with it
$50 says when someone at Nelson sees this, they shout into the machine shop to make a new pair of cold sides with the logos flipped over, just to send them to Mike. :D
I’d almost be more surprised if they didn’t already have cold side housings with the logo flipped. The main reason for mirror turbos is packaging and aesthetics. So, they may already have housing with the logo flipped so it faces the right way.
17:00 there is one more way that's accessible to anyone with a 4 ton press and enough skill to carve out (or have carved with a CNC) two wooden molds, and that is to press two halves of the elbow, and weld down the seam center after clean up. You can bend most alu in 2 mm flavor with just those. IMO, also gives a clean finish product. If you have access to a CNC (one of the small, wood and light metal types) you can even go one step further and do reductions into the piece you're pressing, alu is easy to bend (with enough lubricant, of course). Any 2~3 ton bottle jack and a half decent frame can do it.
In aviation, that nozzle would be considered a "choked" nozzle, which is a good thing. It basically allows you to have the correct nozzle size for your thrust. Fight nozzles are designed to give efficient exhaust to give the most thrust available. It's KIND OF like having a perfectly tuned exhaust on your ICE engine, vs just a regular OEM exhaust.
HIP = Hot Isostatic Pressing. Essentially heating the aluminum to the "Plastic State". then pressurizing with high pressure to close up any casting porosity. making the casting denser and stronger. I've used this in Aerospace for many years.
I'd imagine there should be some compensation added in, due to the material lost during cuts, to get a full 90 degrees. Cool non the less. Keep at it need to see this thing on the water!
Correct me if im wrong but if you have 2 2 1/2 inch pipes merging into a 2 1/2 pipe that then transitions into a 4 inch pipe wouldn't that create a bottleneck in the system? Wouldn't it be better to merge the 2 2 1/2 inch pipes directly into a 4 inch pipe?
Yes, their wye and tight radius elbow are super inefficient, flow-wise. The compound shock losses are going to be massive. But, "it is super compact and looks cool". Those are the priorities here...
@@PbBelly also, its a 1500hp or so engine in a fiberglass shell of a boat. Even if you lose 80hp in that entire charge pipe it'll still be fast as fuck. You could definitely do better if you wanted to, but I seriously doubt it makes any noticable difference.
This isn't a race boat, having the turbo system really compact so his kids don't burn themselves walking by it is more important that making maximum horsepower
Hey guys that 2.5” bend is going to be a chock point. It needs to be at least 3.0” or 3.5”. You just cut your Y pice back to where it is at 3.0” and make another bend up to your 4.0”. That will flow much better and help with your power. Check out flow charts. Cain hard guys.
i'd love to see some really long straight dump pipes off the turbos, just sticking out like a foot past the end of the boat with the water injection for muffling. Jet boat with jet contrails.
So guys I have a question for it being so compact and close together you should have barely any Turbo lag the spool up time should be really quick I really like what you guys Are doing Can't wait to see it finished
Turbo lag is more on the engine making enough exhaust to spin the turbo. Piping length doesn’t make too big of a difference due to how fast pressure travels. I’m no expert in turbo sizes so I couldn’t tell you how fast that set up will spool but they don’t look crazy big so it shouldn’t be bad.
I see that Place Diverter Co. just sold their 1976 Rogers 19' Bonneville jet boat on BaT. Sold for $25K. Looked like a great restoration. Wish I submitted the winning bid. It would be a bitchin float here on Central FL lakes. Great info on jet pumps!
I think “Wifey’s Whip” is a great name for the Eliminator! That way when you gap people out in Parker they know your wife’s boat is faster than their boat 🤣
That's great except "whips" are cars, not boats.
I like signed consent!

Until a flat bottom pops up, but of course a flat bottom can't run the full length of parker wide open unless your crazy lol, like the Daytona can.

That Jet drive is really cool. The boat is going to be awesome
you all should definitely get one of those sweet Tim Mcamis chimneys for that burst panel. who doesn’t love more billet?
For those that already have a miter saw for wood, your carbide blade will cut aluminum tubing just fine.
I was thinking that a Stainless steal carbide blade would have problems with aluminum

17:00 there is one more way that's accessible to anyone with a 4 ton press and enough skill to carve out (or have carved with a CNC) two wooden molds, and that is to press two halves of the elbow, and weld down the seam center after clean up. You can bend most alu in 2 mm flavor with just those. IMO, also gives a clean finish product. If you have access to a CNC (one of the small, wood and light metal types) you can even go one step further and do reductions into the piece you're pressing, alu is easy to bend (with enough lubricant, of course). Any 2~3 ton bottle jack and a half decent frame can do it.
Can also use a miter saw for wood with a Diablo carbide metal blade. Works great you just have to devise a clamp system.
In aviation, that nozzle would be considered a "choked" nozzle, which is a good thing. It basically allows you to have the correct nozzle size for your thrust. Fight nozzles are designed to give efficient exhaust to give the most thrust available. It's KIND OF like having a perfectly tuned exhaust on your ICE engine, vs just a regular OEM exhaust.
Looks really good! I know I couldn't figure all that out. Nice job
HIP = Hot Isostatic Pressing. Essentially heating the aluminum to the "Plastic State". then pressurizing with high pressure to close up any casting porosity. making the casting denser and stronger. I've used this in Aerospace for many years.
I'd imagine there should be some compensation added in, due to the material lost during cuts, to get a full 90 degrees. Cool non the less. Keep at it need to see this thing on the water!
Love all the aluminum. That new jet drive is sexy! The whole setup is beautiful. Compact is GOOD! And yes, Math is hard.....🤣🤣
perfection. not all heroes wear capes.
Correct me if im wrong but if you have 2 2 1/2 inch pipes merging into a 2 1/2 pipe that then transitions into a 4 inch pipe wouldn't that create a bottleneck in the system? Wouldn't it be better to merge the 2 2 1/2 inch pipes directly into a 4 inch pipe?
Yes, their wye and tight radius elbow are super inefficient, flow-wise. The compound shock losses are going to be massive. But, "it is super compact and looks cool". Those are the priorities here...
I agree. I’m guessing they will redo it at some point.
@@PbBelly also, its a 1500hp or so engine in a fiberglass shell of a boat. Even if you lose 80hp in that entire charge pipe it'll still be fast as fuck.
You could definitely do better if you wanted to, but I seriously doubt it makes any noticable difference.
This isn't a race boat, having the turbo system really compact so his kids don't burn themselves walking by it is more important that making maximum horsepower
@@mattbradshaw6456 Why would they be walking inside the engine bay of a jet boat and how the hell would they burn themselves on boost piping?
Thanks for showing the knowledge. Cheers from iowa.
Hey guys that 2.5” bend is going to be a chock point. It needs to be at least 3.0” or 3.5”. You just cut your Y pice back to where it is at 3.0” and make another bend up to your 4.0”. That will flow much better and help with your power. Check out flow charts. Cain hard guys.
i'd love to see some really long straight dump pipes off the turbos, just sticking out like a foot past the end of the boat with the water injection for muffling. Jet boat with jet contrails.
You guys are awesome! Thanks for the entertainment
Great video learned a lot dig the wife’s boat Bad to the bone beautiful boat
This is wonderful stuff to watch!
So guys I have a question for it being so compact and close together you should have barely any Turbo lag the spool up time should be really quick I really like what you guys Are doing Can't wait to see it finished
Turbo lag is more on the engine making enough exhaust to spin the turbo. Piping length doesn’t make too big of a difference due to how fast pressure travels. I’m no expert in turbo sizes so I couldn’t tell you how fast that set up will spool but they don’t look crazy big so it shouldn’t be bad.
I see that Place Diverter Co. just sold their 1976 Rogers 19' Bonneville jet boat on BaT. Sold for $25K. Looked like a great restoration. Wish I submitted the winning bid. It would be a bitchin float here on Central FL lakes. Great info on jet pumps!
