So the 3.5R is making 350 hp on a K20, which I assume is safe and reliable or the factory in England would not offer it. But this got me wondering -- what is the max SAFE and RELIABLE hp one could expect from a boosted k24 without changes to the internals? I have not heard of any issues with the factory supercharged option at 300 hp, but wondering how much more is possible without sacrificing the reliability of the Atom which is one of its selling points?
