3.10/6# is good for ~16.2# boost. 2.90 upper max with a 6# lower may be too much ~17# boost. I don't see a port but assuming you have it.

i dont think its ported but if it is i didnt have it done. im starting to guess it might be ported due to the numbers it put down on the dyno. either that or its a factory freak car. idk

It could have been a friendly dyno... I would do a 2.93 IF its ported... if not, with that lower I wouldn't touch an upper pulley.

maybe it was a friendly dyno idk. once i get a halfshaft and am able to drive her again i will take it to another dyno. the one i took ot to was local and didnt get much business so who know u might be right. i will post new numbers once i get the car fixed. still lost with the car dying tho

Take the plenum off the blower and take a peak inside. If there's casting finish then it's not ported.

^If it's Stieg's or mine it'll be stamped up underneath the snout on the blowers case.
