Sorry Protester, haven't had much action on the 935... still waiting on the engine. Just got the motec rebuilt and reprogrammed. Hopefully in a week or so we can dump it in. In the meantime, rebuilt a 912 and completely rebuilt another RSR switching the front end from a Peter Greg wall dam to a modified FIA front end to accommodate his humongous oil cooler. The red RSR has a stroked out 4.2L motor..... Full blown race car, 480 HP.....Stupid fast. The 935 should push somewhere in the realm of 650-670ish hp.
