Combustion chamber volumes
Turbo Mini Forums

Does anybody know what the volume of the chamber in a A+ turbo head before any skimming or mods. Does 30cc sound about right ? Also, what would the piston dish volume be of a standard +40 turbo piston and the volume of the space above the piston at TDC ? and finally whats a good number for the gasket compressed thickness.

Cheers

BTW - I took my buddy VTEC Pete out for a spin this weekend, and even though I am running her in, he gave it a name, the "Brocket"...cause I'm a brocket maaannn, nah nah nah nah nah nah nah nah nah nah nah....

nope std head is about 24cc

Pistons volume is about 12ccs (assuming 20831 pistons).

Gasket is about 2-4cc

21.4cc is supposed to be standard 1275 head chamber vol, though they can vary a bit.

Cheers Alex,

Just sorting through some turbo heads in garage, wanted find out if they've been modded or not its just that one has had the inlet ports blended, and if I've measured it right the chamber have been taken out a bit too. Will double check against the 24cc's
