hey guys i need some good advice. first lets explain my setup on my G35 coupe manual transmission. i have a pro charger standard kit on my car that come with the fuel system from pro charger, i also did Altered Atmosphere Motorsports EMU Flash. now i want to upgrade the pulley to a 8psi Boost i don't really want the 9psi. my question is, what do i need to add are change to run this reliable 8psi boost?

 

Just by your post , I take it you are not to fimiliar with your SC system . I would find a shop that you trust and can rely on not to rip you off . Ask them what would be your best options .

The ATI SCer makes 7 to 8psi out of the box and the first step up is the 9psi pulley .

 

nope ATI told me that G35 come with the 6psi pulley, and also when i drive the car on boost it doesnt reach 7-8 psi

 

Sorry...I was under the idea it makes 7 or 8 stock .

 

I have the ATI stock setup and making 8.5psi... it has to do with your BOV or BPV the stock one is crap... get a vortech or teh upgraded one from ATi ti will help hold boost better. I too am lookin to jump in the PSI level but looking for around 15psi...

But to answer your question it's just a matter of changing the 2 pulleys that you buy from ATI. I know some shops can make pulley's but I think its almost the same price and easier to just buy them from them. Let me know how it works out and cost I havent had a chance to call ATI to find out cost.

 

its about 300 dollars to upgrade to the 9psi pulley. the same sc we have goes on the 350z aswell the diffrence between our car and the z is the bumper. the z has a whole in the front so according to ati the g is only suppose to boost at 6.5 psi the z boosts at 7. i have the stock bumper on my car along with the stock pulley, when i got it dynoed i boosted at 7.3 psi and made 335.2hp to the wheels and 306.7 lbs tq. that was on a dyno jet and after he warmed my car up. about 6 runs on the dyno all within 30mins. all i need to do is get the magnaflow exhaust plenum spacer and 9 psi pulley and ill be where i want.

 

oh i forgot to mention that is with the stock ati bov aswell. and yes they are good at first but they begin to leak which is NOT good. i want the hks ssq everybody has them but supposively they r the best ones for maf sensors. thats what ive heard. fill me in if im wrong

 

what about fuel and timing, do i need something else other than the stock fuel and the ecu flash?
