Friend put this together and thought I would share. Only works for ST/TT 1, 2 and 3 but that's all any of us are probably running anyway.

Click the link, then go to "file" "download" and open in excel.

Looks like tube frame vehicles will now be able to run ST1/TT1 if horsepower isn't too high.

Is that Ken Brewer's? If not, I can ask for his and send it to you so it lands in the first post as well.

Yep. This is Ken's. He was nice enough to share and thought I would pass it on.

It is actually being used as the official NASA calculator on the ST forum.

It's a great help.
