I know the clear corners will make the car look better. Unfortunately when I have been able to save a little extra money they are not at the top of the priorty list just yet.

No SSX for me I just got a new position at work I can't really take anytime off right now. I can't even do the Dragon run.

I called Cam at Pettit he told me to hold off on the clear corners for now. He is developing some that will be powered by mini flux capacitors and they will be LED. The estimated hp increase will 20 whp per side plus 30lb of torque total.

S/C Compressor Vent??
[QUOTE=Phil's 8;2032669]
Will the compressor vent be shipping with all subsequent kits??
since were talking about gauges...i went with the autometer cobalt series...
Boost/Vac, A/F wideband and Water Temp
although i would have like to have all digital ones....the most important one to
me is the wideband which is digital....of course the nexus where my first choice
but i dont have a sugar daddy at the moment...
/QUOTE]
I've always wanted a younger woman, maybe I should apply.
Cam's sending me a new toy for the s/c (compressor vent). Do you have it yet? It's supposed to help under heavy load conditions

my original dyno (with original tune)
i was able to get my scanner working...finally scanned my original dyno from cam..
this is the first tune...the original tune and the one i am still running today....
every time i got to put a new tune on the car, someone comes up with a better tune...the car is running fine at this point so im gonna wait till all the tunes are done then transfer the best....
that one will prolly be yours juan

I believe we were only able to get 6 psi on the dyno. On my way home we video recorded 8 psi. Also, two more things to take under consideration. There was no ram air while on the dyno and no air cooling effect to intercooler radiators. I do not know (sorry I forgot to ask Scott) the intake temperatures but I'm sure they weren't the best.

Though since your boost is linked to rpm, wouldn't it mean you'd always hit 8 psi at 9k rpm? Or does the SC have a wastegate type setup?

My dyno was almost identical, and peak hp was 260.5, except the temps were in the high 80's that day (not close to 100).
Isn't boost pretty dependent on air temps? This would explain why he's able to consistently hit 8 psi on the highway with cold outside air slamming into his ram air duct and his intercooler heat exchangers. When I first drove the car with this setup (and Cam in the passenger seat) we hit 8 psi pretty consistently, but on the dyno we only saw 6 psi.

Is this the final pulley that you guys have for StageII? I recall reading a while back that Pettit would be releasing a pulley for more boost with StageII.
