ST80 track results
Giving a 3800lb race weight and a 134.73 MPH trap the simple HP calcs say 725 rwhp (should help for the calcs). Piping has 5' of 2.25" piping and probably another 6' of 2.5" piping, all before the intercooler. 6.0L engine. Look at it this way, now you can tell people a definate limit on piping since i've hit the HP wall with mine. Wonder if this kind of stress could have hurt my previous turbine wheels.

I second DrTurbo in that 250 ft/sec is a good limit. Here at work, we keep it below 200 ft/sec. If you map out the losses, you see that they really start stacking up beyond 200-250 ft/sec. 450 is ridiculous. I was concerned with my 3" piping between the turbo and the intercooler because the velocity is around 220. . .

We just need a comparative # not actual. If you apply 100 degs and SAE variables you get comparable #'s to compare the smaller piping to the larger piping.
