Sorry for really hijacking the thread, Randy. The least I should have done, was commented on you great scratch building or commended you for tackling a subject, I've never seen, in scale.
Thanks for the answers about ETs & speed. 7.90s @ 85 is pretty stout for kids & teenagers. Throw a shift in there & leg it out to the 1/4, they'd be in the 12s. I'd say those little motors are putting out a bit more than 5HP.
