Dynoed the car yesterday for the first time since the rebuild.
Dynopro has a new wideband O2 sensor and they let everyone use it for free. I also won a raffle drawing for a free dyno baseline, which I was able to use yesterday. :)
The car is running extemely rich. Way rich. The wideband only meausres down to 10:0.1, and I fell below that between 5000-5500 rpm on the big pull.
The first pull was even richer, as I had the VPC zeroed out and was adding 5% from 4500-7000. After the first pull I set the AFC to zeros as well, and the A/F ratio still fell off the chart. There's a bunch more power to be had with getting to an 11.5:1 or 11.8:1 from my current 9.X:1...
So, with that said - the car put down 626 rwhp and 554 ft/lbs at 26psi. At least 25, maybe 50, hp can be found by getting the fuel curve to something which resembles sanity. Adding a few 4 more psi in the manifold? Who knows. And an exhaust cam is good for another shot in the arm.
I'm pretty pumped. Bigtime. I can't wait to actually TUNE the car and then go back and see what it lays down.
