i will get a pump gas hp when i goto the dyno. i bet it is close to 400rwhp with the cut out open. your right about the intercooler, it makes a huge diference.
let me know when your ready to sell them i still want them. but if not where can i get a good price for them. what do you think about a bigger down pipe instead of the 3". from what i can gather the less back pressure on the turbo the better. so what if you do just a striaght 4" exhust from turbo back. all mandrel bent. whacha think about that. no back presuure. oh i might have 10 on the dyno on pay day. can i make a request. i wanted to run ten pounds on 93 octane with mine. can you see what that does and i'll be sure and shoot that 10 your way i'd send more but its christmas time. i would really appreciate it and see how much timming it can take.

sorry by the way this is hefdaddy i'm on snake eater's computer again.

paypal is cobra99vert@aol.com, thanks guys.

my plan is to start at about 9psi on pump gas(92 octane here), then turn it up about 1psi at a time till it starts to show knock. i dont think it will go much over 10psi. then actualy drain out the fuel and dump in strait 118octane, i never ran anything over 110octane before so running it strait who knows how far it will go. i wouldnt be suprized to see 20+psi and run into some problems that are new like intake tubes coming apart or who knows. i think 20+psi at ??????hp and eventualy lift a head and spit out a gasket. thats what i am thinking but it could be a lot more spectacular.

Even at 20psi, the stock gasket will hold, just as long as it dont ping. The second it does, it will go. I think this motor will hold 15psi no problems because of the shorter stroke and less bearing wear.
