Whilst browsing the various performance mod threads in the forum I've noticed there appears to be 2 different combustion chamber versions.

I'm wondering if they changed at the same time as the tank etc in 2001?

I've never read that they changed the comp ratio.

Anybody else ever noticed this?

See for yourself below.

I think one is the RC51 and one is the superhawk. i would guess the bottom to be the 51. Just guessing.
