Dyno'd Whreatcrafts 432 BBM today made 1608 hp 1055 hp at 8000 rpm still making power and torque but didn't want to go any higher F1x12 Procharger 440-1 heads.

All off the shelf parts

That's impressive. What block?

Indy low deck solid

What psi?
What prep to the deck?
Fuel?
Spark?

Thanks!

Almost as good as his Predator Do you work at Kammer?

Just a friend of chris
20 psi
Alcohol
22 degs timing
Not sure on the deck prep.

Great post! There aren't enough of these high end posts IMO. It sounds like a good combo.

C&S carb with solenoid floats?

APD Carb
Going in 1800 lbs dragster. For anyone that went to the PRI show it was in Indys booth

There has been a black dragster going out to Norwalk for some time,same blower but not your people.I will enjoy seeing another out there.

Impressive for 20 psi.

We are going to build a 477 or 508 SR headed F1X12 next.

Aren't those results kind of weak with a solid race block?

Maybe they can get it in the dragster and have it at MATS in March.

I think 1608 on a 432@8000 is pretty impressive Cab. I think the 1055 was meant to be torque unless I'm wrong........

Yes 1055 was torque and it will be at the mats

Not knowing what CFM the carb is has a lot to do with my thinking it was not making a lot of power, what CFM is it?
The smallest restriction on the intake side of air and fuel will be the limiting factor on power and fuel and air flow
I've never built or race a motor with a blow through carb with either a centrifugal supercharger or turbos, my only blower experience is with pump gas roots blowers on 4 different motors, 3 motors with carbs and one with EFI None of them made over 2.0 HP per C.I. either, let alone 3.+ HP per C.I.
I am probably to use to hearing guys racing heads up with turbos and procharger on methanol making 6.+ HP per C.I. with a lot more boost

3.7 hp per inch with the F1 is pretty good
1150 APD

That is very cool. I have been starting to plan a small cube power adder deal somewhere in the 400ish cube range. 3.anything per cube is unicorn numbers in my world. Awesome job. Do you know any specs on the piston/rings? I am curious what it takes to stand up to that kind of PSI.
