Very cool. Thanks.

I thought the GT4 had an Akrapovic exhaust. Does not appear that way.

Very Cool

Customer Race Program + less then the 997 GT3 Cup Program (albeit a little slower).

Ima build one -- with better parts (Bilstein = lol)

How they getting 480bhp @ the crank? bore & stroke?

[OMID INC]

[JC919]

480hp? That sounds more like the M3 GT2 to me

GT4's engine is completely stock and therefore makes 414 hp + a few more due to high flow cats (made by Akrapovic).

Redline is lifted up to 8.500 rpm. And as I said before there are three different ECUs, Stock, FIA 10% and FIA 7%. That could probably be the difference.

How come the exhaust in the GT4 pics in the brochure looks like it has a large muffler similar to the stock muffler, as opposed to the 2 discrete mufflers in the E9X M3 Akrapovic after market exhaust.

I would have expected a similar Akrapovic exhaust to be used in both applications, i.e. after market and GT4.
Actually, the exhaust on the GT4 that Turner Motorsport acquired looks like the regular after market Akrapovic exhaust.

Rear trailing arm - stock part looks the same. However, there are aftermarket trailing arms available.
