well, I've learned two things here: 1) I don't know anything about exhaust, and 2) I don't know anything about engines. Dang, I should have taken some auto shop classes! You guys all gave me a headache. It's gonna take me a week or more to figure out what y'all said!

>>>*One thing is true, those of in the business who have spent decades, (bit more than 4 of them in this old man's case) know that our engines waste more than they use to move the vehicle.

The trick is how to get at it? Now we know that a straight pipe, somewhere between one inch and 6 inches long makes best power if it is 150% the size of the exhaust valve.

The problem this causes is obvious, mad neighbors and upset police officers, a few fires, minor stuff.

Everything becomes a tradeoff, a balance. The "best" is when that balance suits the driver...

It's all fun stuff, magic in fact. There is still a lot to learn. I know there is around 50-80 H/P and more (heat) going out the tailpipe on the average 22RE when it is running down the road.

If we ever get to the point where we use ALL the energy to power the vehicle, the exhaust pipe will run stone cold.

Yep, fun for me, anyway...*EB
