right now i have the stock pulley on my comtech kit.. i did my own custom piping to run an intercooler instead of the aftercooler and I lost a little bit of boost through the piping..
My boost gauge is reading about 5psi... before i did the intercooler piping and it was ran straight into the intake it read 7psi..

My question is.. do u think i can get a 9lb pulley and run it with my setup. without having to mess with fuel and tuning? since i am loseing boost n with the 9lb it would be around 7psi actually.

if not. what else whould i need to get to make it run safely.

thanks

If you think that you will lose 7lbs with the 9lb pulley - than you should be fine just getting on the dyno and tuning with the comptech FPR. I would recommend that you go with 1 step colder plugs and gap a bit tighter.

Let me know what the dyno numbers are. I've considered going with a FMIC but have always thought that the gains with a AC would be better. Good luck.

Have any pics of the FMIC?

 

c if that pic works.. im not good with the hosting picture thing

 

n no, i dont think i will lost 7psi.. ,, i just thing with the 9 psi pulley i might be around 7.. since im at 5psi with the 7psi pulley

 

Is that your ESM box I see there?

 

I'm confused, your first post says that you have the stock pulley on your comptech supercharger, and now you are saying that you have a 7lb pulley....Someone correct me if I'm wrong, but I thought the stock pulley for Comptech was 5.5psi.

 

You should get like a VAFC or something but you don't NEED it, just maybe should have it.

 

you got it done!? NICE!!!

 

where is the best place to buy a 9psi pulley... n who makes it..

also.. where do i need a smaller belt? or is there enough room in the tensioner.

thanks
