hello i have a 2004 g35 coupe 6m
i have the vortec sc on it with the 7lb boost pully and cat back exhaust
my car made 334 whp and 304 wtq on the dyno. i was thinking of going to about 365-380 whp so im about 10whp/lb any way what else is needed?
im going to get a 10 lb or 11 lb pully and headers is ther anything else i will need to obtain these #s and what is a safe amout of boost to run?

 

Sounds like you need a tune. I thought vortech sc made right around 380whp.

 

oh no its tuned good
and its 410hp at the crank and thats what i have at least i think

 

well u guys are geting high #S i dont know im from canda and at davenport they got me the vortech sc kit and it came with everything and ther are a few in town and they are all runing about 230ish whp
is that low
how can i get more ther is no place in town to tune it becides these guys so what could they be doing wrong? what size pully is every one running mine is 3.33 and thats all i have the stage 1 sc kit

 

I have Pro-1 headers, Resonated TP, and Borla TD. I also have the 3.12 pulley, which is the 9lb pulley and im making prob around 390 w/ the borla TD, my 380 was with the Pro-1 exhaust. If you gonna go with the 9lb pulley I suggest at least 440 injectors and a walbro fuel pump just to be safe.

 

ok sounds good
i though the sc kit came with injectiors and what is the tp and td u are talking about
soory im new to cars and g35 so i only know basics.

 

best way to get 380 to 420 whp on the stock blower is to find a dyno that will print out what you want it to read !!!!! just had to !!!! lol

Here ya go...this is an honest gauge on how much boost you need to get where you want to . Sart with your N/A whp.....if that wasnt exagurated to begine with...it will come out right

 

TP delete the Cats, and Borla is a well know TD exhaust, search it, youll find tons of stuff on Borla. Also go over to my350z.com and search Vortech and just read, you'll be a pro by tomorrow.

 

Wow, that site is pretty frickn accurate!!!!

I was at 250 before my 9lb pulley, now hittn 402...

When you put in 250 & 9 it comes up w/ 403.1

 

Not bad, I have 430rwhp so I must have some additional mods on my car....well for the next few days that is.

 

Man that website is way off or Stillen sucks. I am running 5psi and before the SC I was 243 rwhp and after the 5psi SC I am running 294. That's 51 Rwhp. That is way off of what Stillen states on their website. I bet anything that they used this calculator to estimate what they were hoping the SC would make. I'm calling them in the morning.

 

if you are running a stage2, you should be running at least 6psi. Wow...only 51 rwhp? Something definitely must be wrong!!

 

ok thanks for all the inpot guys
i guess my next question would be what headers should i get whats the best bang for the buck im going to get the 9 lb pully up 3 lbs from the one i have now and i have exhaust so i need headers and mabey a fuel pump and injectors

 

that sige was right on for me i had 232 whp then i have the 6 lb pully and an exhaust and now i have 334 whp so if i get a 9 lb pully and headers i should have about 390 whp
