Would like to see the 8374 graph with better cams. Looks like it makes good power, but, at least in the graph posted, it's not spooling as fast as I was hoping it would.

Hmm, that comparison looks funny, it looks like the 8374 was running at higher boost than the 9180 through most of the rev range. Come to think of it, if they were both setup to make 31.9 psi boost at 8500rpm, the smaller turbo would almost have to be running at higher boost lower in the rev range in order to be at the same boost at 8500, because it probably would have some fall-off.
Anyway, in this comparison it looks like the car would be actually faster with the 8374. But if they had set the test up for equal peak boost, the bigger turbo would probably look better. That's my guess.

First, does anyone know for sure what motor displacement is in the Sierra Sierra car?
Second, can someone post up some dyno sheets of 6765 or 6768 cars with similar motors in here so we can compare?
Thanks!
