So, you're saying that Die cast alluminum isn't better than sand cast? You're saying that 80 cfm more head flow at the same lift isn't better? You're saying that 3 times the oil pump capacity isn't better? You're saying that bed plate design isn't better than main caps? I thought that those things were understood in the industry as being "better"...

And, I'm not qualified to enough to argue with you about exhaust pulse and transient time, in the form of equation. What I DO know.. is that overall RPM where the turbine begins to get going, won't change with the strength of the exhaust pulse.. but, as I was taught, transient time, or the time from which the turbine goes from dead to full tilt, DOES increase with compression ratio increase, or a stronger exhaust pulse at the turbine. So, the RPM that it begins to come on boost, would be virtually the same.. but the turbine speed would ramp up at different rates.
