***Topgunz ROTREX C38R Supercharger Kit***

Best of luck to you! I have every supporting mod required and we were limited to approximately 570whp at 16 psi, hence why I am adding the methanol injection.

That sucks. I made 585whp at 12psi with turbos. I didn't even push it though because it is 93oct.

FrankEtier

What is the tuner saying the limitation is on your car?

The lack of a twin turbo kit.

From my understanding, they can't get any more than 16psi and mentioned a fear of knock with anything over 600whp. Not sure if my tuner is afraid to bring it up more or if this kit just doesn't live up to the hype. I'm definitely not worried about pushing the limits.

I run 17psi on pump 92 with no ignition correction, it's fine but you have to retard the timing so much that the car honestly feels like **** regardless. If I recall right at WOT it runs 8 degrees of timing and that's it.

I also contemplated meth injection as well but there was so many cons to running it I didn't want to deal with that, so I had a 55 gallon drum of e85 delivered instead as there's zero locally available e85 stations.

Are you using a Wastegate setup or trying to control boost with Ecutek and the BOV?

You are just on the wrong fuel. E85 is how folks get the power, even on turbo cars.

JVerge5363

Unfortunately, E85 is not readily available in my area.

That’s lot of boost for 570whp.

Spooler

It's because the timing is retarded due to the fuel. 16 psi on E85 should be around 700whp on a turbo car.

People chasing numbers on pump gas with these small displacement motors.

Mine made 745 on e85 @16psi
