47 hp just from the 264's? ....c'mon

 

dynojet

 

hearing those gains with 264's wants me to get cams now..

 

well you guys believe what you want to. those are my numbers with those mods.

 

Haha, UT_EVO, i know how u feel. I just wanted to stop with my current mods and only add a downipe and high-flow cat, but reading all these crazy HP gains with cams and a custom tune convinced me into doing the same. Hopefully u can withdstand the temptation, lol.....

 

well, its quite unbelievable man. you couldn't even run more than 22psi and were probably knocking at that. my guess is your dyno COLORADO correction factor was having a VERY bad day.

 

i know ive seen that a bigger fuel pump is reccomended when adding cams, what about bigger injectors?

 

no, you don't need bigger injectors. when you upgrade the turbo, you need to upgrade the injectors.

fuel pump is really just a safety measure as the stocker has failed in the past.

 

i am sorry too man but with just that mods you cant possibly get 350whp. it would be nice to get that much horses with just those mods, it more of a 315-325whp range

 

You have a point there.

 

im lookin to get hks 264/264 soon! cant wait

 

i think reasonably speaking cams give you abt 30-35whp.

 

na, more like 15-20whp.

 

i am running 24 psi actually. anything above that and i was out of the turbos efficiency range and was just losing power. this place has dynoed an uncountable number of cars including as many evos as most of the big dsm shops out there. their correction factors are just about right. read a post by a friend of mine "3240" about dyno numbers and correction factors. he dynos his car up here and also at or near sea level where he gets all his work done on his car and the numbers were right.

 

24 should be out of the efficiency range already.
