Why not? do you think that's too low? Remember that you're talking about an emissions compliant engine and that the design is 8-10 years old (don't know exactly when the B16 came out) The F20C1 makes 75 ftlbs/litre and should be about 88% VE.

Re: Lets talk turbos
Lets talk turbos. I used the formula CFM = (displacement*max RPM* 0.5 * efficiency)/12^3 The 0.5 is because the engines are 4 strokes. The 12^3 is to convert cubic inches to cubic feet. I am using an efficiency number of .9 for the 4 valve heads and a number of .85 for the 2 valves. The most intere...

Forgot that was so large. I emailed you a smaller version. That run was made with the IAT sensor inadvertently unplugged. I later plugged it in and it got a lot smoother and gained a noticeable amount of midrange torque, although I didn't get a second dyno run in that configuration. This run was als...
