pro charger vs turbo - 12/10/12 01:17 AM
If you were to build a 450"ish street/strip motor around 2000 hp on alcohol
Would you use a race drive Prochatger or twin turbos?

Would a a F3 Procharger with race drive last on the street?

Depends on your definition of a street car. I run a side slinger and am not afraid to drive it 30 miles. A race drive will eat bushings and the blower might try to eat something sitting down there.other than packaging sure why not.

30 miles isn't going to cut it. I'd like to be able to drive 1000 miles trouble free. Not sure if a Pro charger can do that.

on one trip? I don't even like driving mine on the street anymore since 25.5ing it.
Is this a drag week deal?

not to mention how big of a fuel tank you going to run on alky? you won't even be able to go 30 miles on a tank.

I would. Like to build a drag week type deal. On the street I will just run pump gas.

Procharger would be my choice but 2000 hp at 450 ish cid would likely be of very limited use on the street. I seem to recall some procharged applications that pulled the belt for the drive so not really sure what is possible. My combination should be good for a little more than 2000 hp but has no cooling and would need to haul a fuel tanker behind it to go anywhere.

I basically want to build a Larry Larson type deal just not as fast.
I want to get good gas mileage. Hence the smaller cubes. Just run pump gas on the street and race gas at the track.

Cubic inch is not going to make a measurable difference in fuel mileage driving normal. Now under boost it will make a lot more horsepower.
I’m thinking Larson is at 3 thousand + horsepower.
If you are not racing anybody heads up the turbo (s) would be the easier way for you to achieve your goal without disconnecting the blower.

Doesn't Larsons car go thru parts (rockers, springs...) every weekend? That is a serious race car. I guess it depends on how your welding skill are. A S/C would be easier but more expensive. Turbos are cheaper but require more fab work.

For what you want to do, the turbo would be the best bet. It'd be simple to set up a boost control that limits your boost on pump fuel, but can be cranked up when you run on race fuel. I know of a supra that had two injectors per cylinder and two fuel tanks. A larger, pump gas, tank and a small race fuel tank. Not sure how the setup worked, but he could switch from street to race without hardly any grief. Just an idea. If it was purely race I would say the procharger might be the most simple setup, but for a dual purpose, I think turbos are the way to go.

I guess I am leaning towards turbo. My goal is a low 7 second car, but has to be extremely reliable/street able. I'm probably going to have The Race Shop in WI do the chassis and Goodwin Competition Race Engines build the motor. I've been saving for the last 6 years to build the car. I want it done perfectly.
I wouldn't beat Larry Larson on Drag week, but if I can finish could probably take top 10

TURBO!!!
I've had both!! Prefer a Turbo any day!!! A lot more technical to setup BUT once it is setup a lot easier to work with.
