STL engine builds?

[Chip42]

So, if Randy Pobst is driving the 2350lb FWD car, what weight should the RWD car be for Bill Auberlin to run the same total time.

(credit Greg Amy for this little exercise )

how much hp/Tq? what's the tire size? I refuse to believe that there is a correct generic answer. is the RWD better? theroetically, yes (if the "equal" suspension design is complete crap, I think the FWD actually has the advantage). by how much? too many variables. It works in IT I think in large part becasue the cars are all so IMperfect. there's slighlty less imperfection in STL, and much less in STU. if I had to stick to a swag, I'd use ~4-5% for STL, roughly the same number used in ITS, just because it "seems" to be about right there for largely the same target engine output and chassis but with slightly more weight (so I went down a bit). but I'm not going to say I think it's absolutely right, or right enough for the series.

BUT - Auberlin wont catch Pobst in near equal machines over a race distance. bad example.
