RE: Pistons & Combustion Chambers - For Power |

the yates type heads of which mark speaks were designed for high compression and high turbulance. this does make the second best setup as far as hp and torque are concerned in a normaly asperated engine. a pent roof combustion chamber would be the best as you put the plug in the exact center of the chamber. for the street however you would need too large of a dish in the piston and you would lose the advantages of the yates chamber although it would still be more effective than a hemi(that will start an argument). the problem with the hemi is the air is dead as far as turbulance is concerned. with a supercharger things change though, the hemi becomes number 2 behind the pentroof chamber. |
