all I can say is WOW! its night and day difference between the 8" and the stock 6.87" crank pulley. I havent tested full boost yet since ive still got 9 month old gas but i make like 5psi from a quick stab of the throttle (under load of course).

now the issue is keeping the tires on the ground... I even have BFG R1's I use on the street which are quite sticky and they break loose with no effort.

WOOT!!!:thumbsups:icon_cool:D:w00t::thumbsup:

yeah, really badly. however I dont want to do a mini tub to this car. this is really the widest i can go. not the stickiest though!

ive got a question, i did notice that when cruising on the highway or even around town sometimes the blow off valve isnt open (vacuum variable of course). if im at ~2500rpm cruising without the BOV open venting excess air, am i creating compressor surge??? it doesnt feel like it at all but i cant help but assume that since the blower is pushing X amount of air and it not venting it has to be.

i think im in the market for another (lighter) spring for my BOV. right now it slightly opens at ~13" of vacuum and at idle thats about what my car makes.
