Let's get this straight: I'm not challenging PRH's experience's or expertise. He has way more than I do, because I'm a back yard hobbyist. All I said and I'll say it again, I'm not taking my engine to a dyno. Period. Nothing against dyno's, if my friend had one across the street I'd be glad to dyno it, but I don't. My dyno is the ET slip is what I said. Same as any engine on the dyno, you make changes and go view the results. Exactly what I do at the track.
