2332 turbo crank & flywheel

[Tbirdusa]

My car body guy is working up an engine and I've been asked to help him source crank and flywheel options. I don't have all the engine specs but he's looking at a 2332 running 12 lbs. - 16 lbs. of boost.
He's been convinced by an "old school" builder that he must have a Demello crank wedge mated to the flywheel. Nitrated and such.

As stated, there are so many variables but to just guess that the engine will throw down 240 hp - 280 hp.... is wedge mating necessary?

I'm buying the set up for him as partial trade and I'm hoping to keep it under $1500, but if it take 2 grand for the crank & flywheel.... well, so be it. He will have to sign off and agree to the purchase that I make for his engine but I would like some guidance from you big HP turbo guys.

And yes, he will absolutely beat on this engine. not drag strip but for sure, tearing up a parking lot after hours.

Definately recommended, perhaps flanged is another option

This would be a nice setup and good price too.

My crank and a similar flywheel were in a 2332 that boosted to 14lbs in a sand car.

It is the Scat forged 84mm crank and Scat flywheel.
No wedgemate, just the dowels.

I bought it used and it checked out fine.

you could have 1000hp, if the car has 185 street radials no problem.

What kind of traction is it going to have? Slicks? Sand Paddle?

I'll need to pose that question Jon. I know they are at least a 60, maybe 50's. I know its tubbed and the rear fenders he has widened 3" on each side........and the tires fill it.

I think it's a bit over the top but with the large tires, the stress through out must be just tremendous.

Here is the car. The painted one just got finished and is his sons car.

and a pic of mine just cause I love my car

light or heavy flywheel for a boosted application in a light car? Need to tell my machine shop how much I want my flywheel lightened

I have a buddy running a boosted 2332 putting 224 hp to the tires with a CB regular 8 dowel crank and forged flywheel. This set up is in a street rail buggy (light) with big drag radials. I would recommend in a heavier car or any more power for sure, you would want wedgemated or flanged. Those tires pictured are big, just not sure how well they will actually hook up which will be the deciding factor

I have a 12lb on my race engine. It really doesnt matter once the turbo kicks in the engine will spin up up quickly anyways. 4500-7000 is pretty much instantaneous.

Load does matter. But a lightened flywheel isn't going to make or break it. Ever try to rev a turbo motor with a BIG turbo in neutral and see how much boost it makes? I have.. almost none. Put it in drive and the more 'load' you have the earlier it'll build boost. Lighten every friccin thing in the rotating assembly and you'll need to rev pretty high to take advantage of a larger turbocharger. Things have to jive, weight, gear ratio, tire size, displacement, size of turbo, target HP @ what rpm. You don't just guess and then toss things together and hope for the best. Nor do you rely on hearsay from internet. Find credible resources and build from there.

thanks yall. Yeah im building kind of an odd ball turbo build. 78.4mm crank, 86mm chysler pistons, 5.5 inch rods, stock cam, ported dp heads, 37mm throttle bodies with water injection, etc. Kinda budget kinda not. will be fun. aiming for 160-170 whp at a bar+ of boost at 5kish rpm.

Since, im having my flywheel resurfaced and balanced anyhow, i may as well just have them lighten it. Should help me get off the line a tad better.

The only thing i noticed when going to a lightened flywheel was you had to feather the gas a bit more to ease off the line.
