[QUOTE="David Trustrum, post: 208693, member: 21529"] The Chamber that the powervalve opens is a ‘disrupter’ to reduce the effects of the returning wave from the pipe when it’s effects are unwanted. It closes when the wave is in sync & it'’ effects are wanted. Thus volume it not critical as such like a intake boost bottle (which is another story I won’t bore you with). Typically there is a max compression ratio for top end, assuming consistent use of decent fuel, ignition & head shape (MSV etc). On a stock engine that is set up to account for manufacturing tolerances & the assumption the owner will run on the cheapest gas he can find. Lowering the compression ratio will further reduce the efficiency of the engine. [/QUOTE]
