Re: New dyno results!
Link to the video. At the end it shows 414 rwhp but that was a false reading from hitting the limiter.

Re: New dyno results!
Car sounds great! Which exhaust do you have and are those 18" wheels?

Re: New dyno results!
Saw this bad dad today. Really good looking car. The white plenum and valve covers is brilliant touch.

Re: New dyno results!
Nice improvement but you're running dangerously lean in the upper RPM range if your AFR graph is correct. Suggest you add fuel to get it into the 12.5 to 12.8 range.

Re: New dyno results!
I would not characterize the AFR in the upper rpm range as dangerously lean.
13-13.1 I believe is fine. Frankly, I would lean out that “sag” in the mid range and probably take out a bit of AE in the upper part of the AE table. I would try a bit more fuel in the top end just to see which way the power goes as a trial. What was the SA for these run? Did u check for knock?
