well iv spent a bunch of $$$$ just to get this far I don't have times or hp yet still need tune and some more parts for the needswings fuel mod.. but ill be pushing 14psi from the turbo to start and I went back to stock pulley so that the turbo will have an easy time keeping up both should stack to 28psi but if that don't happen the turbo is good for up to 35psi at 750hp so i have plenty to play with... I know ppl are going to be upset i don't have more numbers but I don't have the $$$$ to get it all dun right now.. but it will be .. and ill try to keep you all up to date as the numbers come in. all the oil and air concerns are taken care of all piped in i have the oil coming from where you would put a oil pressure gauge on the front of the engine and being pumped back into the oil pan.
