i've had heaps of people PM me about compression and my old NA itr and the h22a prelude.

Instead of replying to everyones pm, heres teh short of it, i dont know the limit of NA CR pistons as I am not rich.

What i do know is this, the highest i have ever run is 13to1 Compression, on 98RON optimax, and it has been fine!
