My 95 mustang is running a procharger the engines long block is stock ( only bolt on items ) such as long tube headers ,typhoon upper and lower, pmas MAF, 42lb injectors and a hipo fuel pump.
I currently have the 9psi pulley on it and it was tuned with an sct chip for this setup .
it only actually gets about 7 psi from this setup. I was wanting to put the 11 psi pulley on it hoping to get about 9 psi from it. it makes 300 hp at the wheels with its current setup.
will it handle the smaller pulley ok or would that be too much on the otherwise stock engine?
and would I have to have it retuned again for the smaller pulley even though I am only looking at about 2 psi more? or could I just drop the timing a cople degrees and get away with it?
the current tune keeps the A\f at about 12.5 to 1 I have heard some say that is a little lean, but I thought it was perfectly safe.
I am going to send off my sct chip to be read so I can put that program into my tweecer chip so I can do some tuning myself.
Oh let me tell you what my final gaols are ( that may help)
I would like 350 hp at the wheels but also a little more grunt down low at say 3000rpm.
My thinking is the smaller pulley will build more boost sooner and that should help bottom end while putting me closer to my 350 hp goal also.
That plus the gt40 p's and an e303 is my winter plans.
What do you think?:yes
