Although most guys that have tried it slapped on a turbo, cranked up the boost and blew up there engines and called the renny weak. While it does have its flaws, no engine doesn't.

I think the side exhaust ports on the renesis are more restrictive than previous 13B motors... they flow plenty of air for an NA 8, but when you start turning up the boost they might be a limiting factor. It also probably doesn't help that a lot more hot unburnt combustion left-overs end up back in the combustion chamber instead of going out the tail-pipe.

MM typed up a bunch of math in a thread somewhere... but that's all theoretical stuff based on air flow going into the engine. I don't think anybody (other than possibly Mazda) has done flow testing on the exhaust ports to determine where the ceiling is.
