i'm gonna install an turbosmart FPR ASAP and throw on the 6psi pulley...right now it's the 4psi stock pulley.
afterward, i'll go for a proper tune and hopefully i'll break the 250whp mark
afterwards I'll get meth and up it to 8psi.
what kind of exhaust are you running, i can see 250whp out of that pretty damn easy at 6psi maybe even more.
Im running 5.5spi and mine numbers are good.
ur numbers are definitely impressive for a 5.5psi pulley. your engine must be in pristine condition.
the 3VZ compression is lower and 1MZ breathes a tiny bit better up top.
i do have a full custom exhaust though...3" from the headers, hi flow cat, 2 resonators and a magnaflow 3" dual outlet muffler
i can only hope for a lower number so that i won't be disappointed if it doesn't go over 250whp
