Granted I know you would have to up fuel system/internals/drive train/etc to reliably run more boost than the standard sts system, but just an idea.

Scott, I rode in your car yesterday after we finished it up. That thing is an animal on high boost, you'll like it. I want to see some track numbers!! As for the lag, it's pretty much non-existent. You may have a little more lag if it were a 76mm, but it really could make better use of it. Boost start dropping off at about 5k. You would see more power up top like Jake said. Food for thought.

Hey Big Bad Black SS, the rimes on the back are 15-10 with 7.5" backspacing, with MT ET street radials 325-15/50. The fronts are 3.5-15 with MT sportsmans 26-7.5/15LT. I went with the "8 ply" front tires, because all others are "not" rated for the weight of our cars. I hope that helps. If you do a search i did a thread on what all i had to do, to get these to fit.

Hey Longrange4U, I still have my SLP LT's. As Jake said the exhaust is wrapped fron the collectors back. After the guys @ EPP changed around and replaced things on my set up, this thing is a beast! With my Vigilante the power comes on like a shot of NOS. On low boost 6.8lbs, my torque is 506lbs @ 3350rpm and @ 4000rpm its 633lbs. On high boost 13.5 the torque hits 637lbs @ 4250rpm and at 5000rpm its @ 705lbs. Zero lag and instantaneous wow-baby!!

I don't like the idea of just poking a hole into the oil pan and threading in a pipe fitting, so we removed the pan and welded in a bulkhead fitting. Bob
I am impressed with your oil retun into the pan idea (like a Vortech). Do you have any pics...to see location, how the bulkhead is positioned, etc? I'd be interested in doing that little mod myself.
