Sun, 08 September 2002 03:34 Bill Sherwood.....no offense on the idea but how can you expect to 'breathe' the same amount of air at the same speed on both pipes ?? As for head work, a smooth finish on the intake ports and as mirror as possible on the exhaust ports. You want that fuel/air to spin on the way in, and get out after it's burned. If you can get some 'vortex' action happening in the intake, it'll work like making a whirlpool when you drain the dishwater out of your sink. When you create a vortex, or helix, you increase not only the velocity which slightly compresses the air, but also vacuum at the top of the vortex which sucks MORE air down with it. Think of it like a free turbo. Note that the intake ports curve into the cumbustion chamber and the exhaust just goes straight out. That's how you want to approach the porting. You want that exhaust gas to vacate ASAP after burning, so make sure it has NO resistance and not only will it exit faster, but the smooth walls will be less prone to trapping carbon particles and such. ...I'm thinking this (from experience) would broaden the powerband all the way across, more poop per puff.
