I'm back with new numbers.
And much happier, although I need to do more tuning. This was on a dynojet. VVL activation lowered to 5000RPM, it was 5200RPM before. No changes other than that, and not being on a mustang dyno.
Recall last week it ran 195hp, 133torque on the Mustang dyno.
Tonight I got:
206 HP @ 7920 RPM
148 torque @ 6675 RPM
So it matches what the engine made previously, although it was a different dyno, except I made 4-5ft lbs more in torque. The previous highest run was done with the stock pulleys, I have the G-spec crank & water pump on now. Perhaps the gain is from them, perhaps not. Hard, almost impossible to tell.
The run with the highest numbers was in 4th gear. 3rd gear runs were actually lower, 199, 202 etc.
Another interesting thing to notice is the motor made its best of 133ft lbs of torque @ 7108 RPM on the mustang dyno, but made 148 ft lbs torque @ 6675 RPM tonight, a 430+ RPM difference between the two, and of course a 15ft lb difference between the numbers.
So a bunch of you were REALLY close in your predictions, so good job I think someone even said 205hp.
Glad I found a seemingly more reliable dyno this time. I'm going to mess with the WAI/CAI setup and VVL activation point and then return to the same dyno in a few weeks to see if I get a difference.
