The Dyno run was made on E85, it is a flex fuel car, there is a flex fuel senser input to the Autronic SM4 and it will ajust fuel,boost,ing maps, based on % of ethanal.This dyno run it was 72% ethanal-28% gas. Bump in HP chart I think may be tork converter slip,so we stoped tuning, Luke Stubbs tuner of this car thinks,27-28psi boost could make 900+ HP. Intake has no floppy valve.

Congratulations, That really is amazing especially since it is on a
bone stock motor without any internal mods what so ever.
This should help the rest of the guys with boost to see what a stock
block can take as long as it has a proper tuneup.
Now go build that purpose built low compression motor and be the first
928 in the world to crack the 1000 rwhp barrier !!! Great Job !!!
I think everyone here would like to see some pictures of the car itself &
and a few underhood shots .

I believe that Todd can make 1000 on this block without any change in compression. Lower compression is for getting out of detonation. There is none here.

Wow, an amazing achievement but how much can the stock crank case/girdle handle before it let's go?
I think with that amount going to the rear wheels the last thing I would want is for the wheels to hook up big time- something must surely give [heaven forbid].
Fingers crossed it all stays together for you- to think I would be happy with half that lot turning my rear wheels!

Todd is controlling slip with various factors. CV joints, transmissions, TTs - these break from undue vibration and harsh "release-catch-release" events just like a block and crank and rods break from detonation and not actual power production.

Let's also not forget this isn't Todd's first Rodeo. He's not just some guy who threw this together all *****-nilly without taking everything into account.
