Re: Engine hours on RSR sprint engine

Tim,

Go with a 3.8 cup build. An rsr engine isn't a cup motor, and you are playing with fire trying to rationalize how long you can go. Btw - the 3.8 cup likely has the same hp as the rsr engine with restrictors.

I haven't tried my 4 liter 997 GT3 RSR motor yet, fresh from PMNA - I am sure it is a monster, but the conversion costs alone from a 3.8 rsr motor was close to $80k.

Best,

F
