currently me running the apex n1 which is a tad less than 2.5(2.45 or so),
so far not fully tuned my car put down 310 using the vortech s/c @ 5 psi is what we read, either way, do you reccomend I get a bigger exhaust? If so how large of diameter?

mods
EMS
apex n1
vortech s/c
apex grounding kit
RC 550 injectors (not installed waiting for full dyno session)

running 11.6 to 1 at the moment


thanks in advance

 

Just so you know, the stock unit is good for 400-450hp. It's what I'm running.

 

Vortech?? -> 5 psi?? Did you get an aftermarket bigger pulley?

 

nope, same pully, it reads 4.75, i'll check the psi when i dyno it to see how off my guages are, i have those aem serial guages, nifty little things but lets hope they are accurate

 

The reason he's confused is because the Vortech unit runs 7 psi stock...Comptech runs 5...
