If you don't mind of course. Plus a few more pictures would help as well. Ed
Ed,

As Diverdog posted above, the current engine is a Vison built 3.8, not a 3.4. The 3.8 makes about 360 RWHP unrestricted, but we run an intake air restrictor to hold the RWHP to about 335 to meet class rules.

However, we did race the car for several years with a 3.4 Gen 1 engine. It was built and prepped by Vision Motorsports and made about 305 RWHP. This engine ran an EVOMS program, larger TB, decked heads, headers, open exhaust, UD pulley, etc. This is pretty much all you can do to a 3.4 to make power, so I would say that is about it for a M97. There may be a bit more in the 3.4 engine, but it would require changing theintake manifold as our testing showed this to be the final, critical restriction.

As for the rest of the car - it has not been street legal for quite some time. I think we removed maybe 120 pounds of stuff while it was still street legal, but that is about it. The car ran Bilstein PSS9s at the time to meet class requirements.

Now the car is a fully gutted and caged race car (for the last four years).

We run 9/10 x 18 Fikse Profil10 wheels with 250/650 and 280/680 Yokohama slicks.

Brakes are stock calipersF/R, stock rotors in the rear with Wrightwood Racing Indycar rotors up front. Pads are Pagid Blacks. We also run the 997 Cup dual master cylinder system and a Teves motorsports ABS.

Steering is converted to the GT3 Cup electric system.

Suspension uses JRZ TA dampers, Porsche Motorsports, Tarett, and Kokeln parts, and some trick geometry changes.
