Bum Dope

23 October 2003

I recently told a fellow he should be using a different cam in his engine.

Later messages made it clear I had been talking to the wrong guy. (I get lots
of mail.) Trouble is, now I can't remember WHO I was talking to. So here's a
general retraction, cross-posted.

If you're planning to fly behind a stock 1600cc VW engine I think you should
keep the stock cam. That assumes you're swinging a long, efficient prop at
2500 to 3000 rpm. The cam I referred you toward does fine on big-bore strokers
but does WORSE than the stock cam when used on engines having displacement of
120cid or less. (Stock is about 96cid; 1834 is about 112.)

If you went ahead and bought the other cam, I'll buy it off you.
