Sup guys... I wanna get a Comptech supercharger with aftercooler... but I want to run around 9psi - yea its high but oh well... What should I run as far as management , should I get a apex-i VAFC2 , or stay with what they give me? Also what pulley will give me what i'm trying to get and who makes it. Thanks for all the help
-FI noob

 

The stock injectors are only good up to around 7 pounds of boost. After that, you run too lean and you'll blow your motor. You can get bigger injectors, but you need a standalone to control them. Going from stock boost to 7 pounds is cheap, but goign from 7 to 8 or 9 costs you an extra 2 thousand dollars

 

Dear noob....love that term...
Im running rc650 injectors with a comptech system
aem ems
also I have a 3.5" pulley = (for me stock motor) 11 psi
aslo have a shorter belt (dont have the part number its a goodyear a search will find it)
I would reccomend ti retainers (supretech or rev)
and change the valve springs search youll find info
and do the oil squirter upgrade maybe a clutch (competition or act)
kane.s2k can help you out with any parts you need.

feel free to pm me with questions if you have them

 

you need 550cc injectors, a tuning device like emanage or EMS, 3.5 inch pulley-you can get tech2 or ASP and time on the Dyno

 

What's the smallest size pulley (WITH aftercooler) you can run on stock injectors and no tuning? like, what size pulley would yield 7psi?

 

call comptech get the ap2 pulley size or get one through them
adjust the fpr
get a belt...

 

4.0 inch pulley for 7psi, that will max out the injectors

 

3.5 for 9psi right? or is 3.5=9-11psi?

 

depends on rpm 9200=11pounds 9000=around 10+pounds

this is on an ap1...

there are a lot of variables involved here as far as what size pulley will give you what amount of boost too much to go into here but search around you'll find a bunch of stuff about it..
