I could be way off here. To check if someone had a sealed crate engine modified could exhaust air flow at a certain RPM show evidence of? Tired of seeing the same cars pull away off the corners after entering on a bad line when they all are suposed to have the same engine.

I tell it like I see it.

I believe you will find the top teams are buying 6 or 8 crate motors at a time, dynoing and keeping the ones to their liking and selling the rest.  We ran a crate in a limited late model against open two barrel motors and had some success,  we were down 125 to 150 horsepower but the torque curve was very desireable on a slick track.

I dunno. I'm inclin to believe that an engine builder would dyno all his engines and market the better performers to racers willing to pay more.

I know a owner tnat never checked spark plugs at all for to rich or lean, he never checked the timing, and if he used 18 gal alcohal on a night he would put all 18 gal in tank for TT, heat and feature.

What track you talking about?

I have some friends that run sealed crate engines and also know a guy that markets them thru a large performance shop. They provide dyno sheets and there is a difference.There is also a shop that can reseal an engine and tech cant tell so its not a fool proof science.
