no more EGR ??

[Jolly Roger VX'er]

Guys, EGR's main purpose is to reduce the combustion chamber temperature. If you block off a working EGR, you will actually LOSE power, as the combustion chamber will be that much hotter when you step on the throttle. If blocking the EGR appears to have improved the engine, that's because there was something wrong with your EGR system in the first place.

I agree to disagree. The EGR's main purpose is emission control by "reburning" the exhaust gasses entering the EGR pipe on the passenger side of the engine block. It achieves this by sending exhaust gasses to your EGR valve which sends them into your intake to be sucked back into your cylinders for re-burning. The result is lower cylinder temperatures because the cylinders are not burning at high efficiency due to the "smothering" going on. Eliminate the exhaust going in during the intake stroke and you have only fuel & air going in. I've done this mod on my '82 Trans Am, '88 Fiero, '79 Bronco all with improved hp as felt by my butt dyno. I don't care if nobody here does it...I'm doing it. I'm only concerned with my PCV functioning which in my opinion could lead to oil burn-off if the EGR is blocked & the PCV ceases to function. THis already has happened in the past...that's why I have a breather cap installed so I can SEE when this happens...plus pull the little dipstik thingie to check the oil level.
