    Guys with supercharged cars: PSI?

    Im seriously considering boosting the car this year with VF Engineering. I had a 1998 VW GTI VR6 Sgt3 with their stuff years ago and it was an absolute blast.

    For the guys who are boosted: how much PSI are you pushing with your respective setup? I know nearly all/if not all the people on here are rocking the ESS kits. VF states that the kit comes set at 6psi. I emailed their technical email address inquiring about an option to bump the tune up to 8-9psi. My motor is completely stock, I dont plan on changing that aside from MAYBE an exhaust (sensitive subject, Im super picky on how an exhaust sounds). I additionally was planning to add an oil cooler to the bolt on setup. I would probably do a very mild upgraded clutch that still felt mostly OEM once the stock one gives out.

    What are your alls thoughts/opinions?

    Edit: I apologize, if someone wants to move this to the engine/technical section.

    I went with the ESS Stage 1 which is 6.5 PSI due to the fact that i have an AT, not stick, so that's the safest route. ESS vs VF choice was going for more torque at lower RPM range. If I had a stick I would have possibly gone for a Stage 2, which I am guessing is 8. A Stage 3 is even more. The Stage 1 is tame to drive, but gives the car nice oomph. There are a couple other Stage 2 cars on our site.
