I was thinking 12 psi to be safe, but at the same time i just wanna throw 14psi at it, this will be on 93 octane, any suggestions would be appreciated, thanks.

i was going to do 14psi, but Jeff knowing that i want it to be at least a little conservative, recommended against it. With my setup, and 12psi, i'll hit occasional knock and have the ECU take out some timing. I'd be afraid of running higher boost levels on pump gas, with not knowing the quality of fuel and because you no longer have the thicker headgasket as a safety net from blowing a piston ring land.

 

Matt just so you know John still makes really good power on his setup with stock compression. You have a Full Race setup so I would think you should be the same amount power wise as John. I wouldn't go more unless you want to consider doing meth injection.

 

i thought that around 500 whp was the limit on pump, so i'd stay around that

 

If he still had the 3mm head gasket yes but now that he is stock compression its completely different.

 

Listen to your tuner don't guess

 

Hey Matt have you talked with Evans yet and asked his opinion ?

 

i thought i specified stock in my post? i don't know what it would be with a hg

 

Well baring in mind there are many variables to each setup and the efficiency it has making boost. But I don't think you'll find anyone running 500 on pump gas and stock compression. Some are close in the high 400's but nobody knows how long and or how reliable that is yet IMO.

But as spectacle has already posted I would talk to your tuner.

 

I agree with this guy
