From: Tom Jennings <tomj@xxxxxxx> To: mail@xxxxxxxxxxxx Subject: Re: Mufflers-another scam item Hey, it just occurred to me, for testing headers for flow, which sounds like a bunch of effort since there's 4 outlets (per V8 side), why not flow them backwards? Attach the outlet (bottom) to an air source, put a false extention on the "inlet" end for a few inches, measure pressure/flow there? Pipe is stupid, it doesn't know left from right. =================== Somone on the JYTurbo list tested Intercoolers with a fairley simple air source & meter > last year..... I'll see if the info is still there. Anti-Reversion designs > wouldn't that make a difference when sending the air into the exit >? Best Mufflers I know of are the SuperTrapp Disc Type > patented< that mount to the end of your exhaust Pipe....... comes in Stainless Steel & you can Add or Remove serrated Discs for Louder or Softer and these only allow the Exhaust to Exit . Once the Flow Pressure drops these Discs clamp shut > blocking 'Inhale'. No other Muffler has this feature > that I know of. Originally Designed for Race Motorcycles back in the late 1970s. Brien.
