Hehe...My Suzuki LT250r Quadracer that I am racing next year has less than 50 p.s.i. LOL!! (A ring decided to snap at very high rpm, when I took the top end apart, I found the ring...stuck through the top of the head and the face of the piston!)

I dunno about my other stuff, haven't checked in quite a while.

245!?! That's a bit scary. Although my Quad4 pow'red Grand Am had 210 (10:1 compression) so I guess that's not much more.
