Building a Big Power Whipple Supercharged Big Block for a Really Cool Application
Вставка
- Опубліковано 9 чер 2024
- Speedboats can place tremendous stress on their engines because they will make full-power blasts for sometimes an hour or more. We build a Whipple supercharged big block Chevy (actually two of 'em) to make nearly 2,000 horsepower worth of thrust for a ridiculous speedboat. Check out the differences versus a similar build for a street machine or even racing.

Whipple twin-screw are so sick. While I am a turbo guy at heart I absolutely love screw blowers as well.
The technology and efficiency of screw blowers and turbos is undeniable but I’m going with an old school roots blower because none of the others have that’s same sound, feel or look. I’m just old school I guess.
Always a pleasure to watch! Thanks for your time and work you invest. All the best from Nienstaedt, germany. Tim
Hey, thanks for the kind words!
For anyone not familiar (I wasn't, and had to look it up), that butterfly valve built into the upper intake manifold-as seen at 16:34-is a bypass valve to let pressure out of the manifold when no boost is needed (like at idle or on deceleration), which helps fuel economy by reducing the amount of air/fuel mixture going into the engine. Or at least that's my understanding!
Those valve covers are awesome. They would be cool on a car
3/4 mile at at average speed of 90mph still takes 30 seconds. But WOW! I would like to put those engines in my 41' Commander. That yacht would probably do 50mph and instill terror in those little wakeboats.
Great video as always
Much thanks!
140mph on the water is 'VERY FAST'
Yea to me that’s like going 200 on land that’s wild
75 on the water is very fast! Lol
Anytime you post a video my day instantly gets better!
Awesome! Thanks very much!
This is great, one of your best! I particularly liked the end where we got to see the engines in the insane speedboat and some action, thanks and please keep vids like this comin'
Thanks very much! And thanks for watching!
Again very nice thank you.
I'm seeing that the corvette is progressing nicely
Impressive ! Many thanks.
Another great video, Jeff! Great job!
Awesome amazing. Thanks for the build video. Please get a vid of you shotgun in the boat when these bad boys installed.
Thanks!
It’s a smile till you look at that fuel gauge! 😂
Man I absolutely love the videos you make. I never miss an upload. Thank you for the great content. I've watched every single video on your channel and can't wait for the next upload. Keep up the great work 👏
Thanks so much!
13:41 take it easy with that pushrod! It hit so hard going in, it blew out the mic 😁
You got it! It's all about horsepower for cars; torque for boats. I got taken for $12,5000.00 for a "marine engine" from a hot rod shop. "Oh yeahhhhh, I do marine". Sure you do,,,,,,,😡!!! Engine sounded like a bucket of nuts & bolts; less than 1 week after it was installed. So, I packed up my Cigarette & sent it to Hawk Marine on Thunder Alley in Miami. I got a Merlin motor built; Merlin block, heads etc. It was a 557 ci; 640 hp. For insurance purposes, the boat was rated for no more than 600 hp. I knew I would lose 40 hp through the TRS drive; that's why I asked Hawk to hit 640 hp on the dyno. Hawk did a dynamite job, couldn't of been happier!!! Money? Right around the same from the hot rod shop. Top end for the Cigarette, when done; 73 mph.
Ouch! I feel you. It seems like I always learn my lessons the hard way. Glad you've got a good motor you can have fun with now, though
@@TheHorsepowerMonster I didn't really know the difference ( hot rod v marine) at the time. It was a 1986 Cigarette 24' Firefox; sold it in 2002 I believe. Next boat? Cigarette 38' Top Gun, pre 2000; not a fan of step hulls. I like a clean 24° deep v hull. Thanks for listening, great video. You obviously know what you're doing! RESPECT 😎.!!!
What a fabulous video. All of the interesting information, without the cheesy hype that many others resort to. I've just subscribed and I have lots of your videos to catch up on.
Awesome! Thanks a lot!
Love your content! Keep it up !
Thanks! Will do!
I just watch and dream !!thks
I'd like to see the individual cylinder AFR data just to see the distribution of the intake and injector design.
I cannot get enough of your videos sir, I love the content and appreciate the work you put into the content! Keep em coming and I'll watch them multiple times!
A video premiere! We're bigtime now!
And in boats, it's like going up hill with a load the whole time.
That's a great way to express it
Absolutely amazing, as always. Great video narration also!
Thanks!
@@TheHorsepowerMonster do /oh ;ave
When I heard the Wipple scream the hair on my arms stood up. LOL I'm going to have to get my Ford Lightning out and go for a putt 😀
Beautiful❤.
awesome stuff, brilliant video again thx!
Thank you very much! And thanks for watching!
sounds awesome what a beast those should move that boat lol
love it john nz
When the junk yard gives you a lemon you turn it around and make horsepower lemonade
Wow!
Perfect 👏
What a great build ! I was wondering about the fuel injectors if they pulse at the same time or are they actually staggered as if they were located in the actual ports of an intake manifold and how well is the fuel distribution to each cylinder? Your builders are masters of their craft . Keep up the great work and some more great videos .
Hey, thanks!
One head bolt on each bank or per head. It was a CBB cast iron (pre modular) I believe Merlin cast theirs to be compatible with the Chevy Big Block accessories and components with minimal or no modifications in which case they usually run 17 Head Bolts/Studs) per bank or head.
Love this channel
Thanks very much!
@@TheHorsepowerMonster So much better than than awkward scripted shows, badass engines and useful info. Thanks for the good work!
Whipple for the win..💪😁😁
Pretty mild tune 4 this set up . Will last a long time . Really nice build . Wonder how much more hp with the Big 4.5 ltr Whipple supercharger on top . Not even 10 lbs of boost .
you should make a video on lash and lift and what they do
With all that wonderful milling capabilities, I wonder why they don’t take the extra time to recess each block to head coolant passage (orifices) that pass through the deck, to accept a pressed in dowel with the head recessed to accept the protruding portion of the hollow dowel, and an o ring slid onto each dowel. It’s my personal hypothesis for use in boosted high output extreme conditions with a pro fogger set up, to solve the issue of cylinder head migration, you’ll have some degree of lift, in diesel and methanol applications, more in Nitromethane Alcohol fuels, and sleepy hollow impressions for top fuel, but durability and reliability of the gasket’s coolant sealing keeps the oil and combustion chambers free of H2O based pressurized liquid, as well as any escaped compression and power stroke high pressure air hot pressurized flame from purging the coolant via radiator cap, by bullet proofing the cooling systems internal weak links (i personally want my weak links where they’re easy to locate, quick to fix, cheap, and an item you can obtain just about anywhere, or carry extra. Not everyone has an 18 hole Chevy Big Block gasket, or radiator coolant fill cap.
I was about to be like WTF on the water you can run a lot more boost and timing. But it sounds like they got it dialed in on the boat.
Damn
What brand of starter did you use ...i like that sound ???
Not sure. The starter is bolted to the dyno so it doesn't have to be bolted up with every engine. I think it is a Powermaster, but not sure
How many hours or miles do you get before a full rebuild? Go fast boat need a full rebuild after 50-60 hours. or 5100 miles.
Whats the compression ratio?
Great video!!!! Approximate cost for an engine like this?
If you have to ask, as they say.......
Around 45k
@@wymple09 But if I don't ask I can't write a check. 👊👊👍👍✌️✌️
So the owner has a 2000hp speed boat and a Motorola Razor. All priority seems to be in place here...
lol
This shouldn't be going in a speed boat. It should be going in that Corvette beside you.
Intake part number ?
Please tell me this is a 502 build
Can these engines be placed in a car, with minor changes
Yes, they were really just adjusting their automotive engine packages for marine in the first place
Cool, thanks
What would be the average cost for one complete and ready to drop in and hook up
A couple of motors and a couple of number six drives to hold the power along with a couple of props that can cost a few grand each it's easy to get a hundred grand in your drive train.
Did you ever check out Nelson racing the boat engine he made oh he built I think it was like 8500 RPM or 9000 RPM non stop and stop I think 1500 horseshoe like that
No assembly lube on the cam???
He paints the lube on the cam bearings before sliding in the camshaft.
990/1000” = 99/100” or 10/1000 under one inch.
are ALL monster motor shops out east ??????🎉cuz ive NEVER seen a YT channel from AZ that makes MOTORS !!!!!!!!!!!!😢
how do ya KNOW that EVERY step WAS taken and care taken along with cleanness done w/o know ur camera hidden in THEIR shop caught everthing ! on this channel u SEE SOME of the tlc used !
anyhow......
Love it! The 2004 cell phone footage of the boat motors running was a little off-putting. Would have been better with a picture instead. Other than that great vid.
Yeah, it definitley wasn't the best! But I wanted people to be able to hear the sound. You just got to work with what ya got! Thanks for watching!
@@TheHorsepowerMonster I appreciate the reply. You are absolutely right. Guess it is lessons learned for next time ;)

marine engines are always going up hill.
