It *was* 150# heavy, now ~240# heavy since we just got 5HP back... but the new wheels and tires in the back should get me back to 205# heavy... Back to back testing should give us some real numbers on what rotational weight is worth in these cars. It probably won't be until the end of January, but anyone want to guess what 35# of rotating weight (mostly off the back tires) will be worth in E.T.? I've read anything from 1.5 to 10x the static weight. My previous calculation show about 1# = .003 even in the 1/8th mile... I'm guessing the new wheel & tire combo will be worth .25.... could there be a high 14-sec run in the Turismo's future?

Rule of thumb, 1# rotation to about 8.5# static.

Sorry Mike, I focused solely on post #13 instead of #15 as well (which makes it more of a bummer for you too) . I hope that testing yields some very positive results for you and your Turismo!

Hey Beard I have a 115 lb driver. I want him to drive that car anyway to learn how to drive a BIG CAR even though its 2 seconds slower than his Jr. But wait with him in it maybe 9.30?
