At 15 psi on a normal street car I'd venture a guess of 230-250. No way its running 350 at 15 psi. Drivetrain loss is estimated at around 22% AWD I think. Weight depends on year, RRE posted corner weights of some cars
here. Dry 1g AWD's are supposedly around 3050lbs and I thought that 2g AWD's were into the 3300 lb range, but RRE's is apparently at 3110 with a 1/2 tank.
I saw that 499 whp E316g thread on Tuners, that shit is crazy! It was Curt Brown's DD right?
