Lito finished with my tune today, remotely on the DynoJet at RMCR here in Colorado Springs.
Keep in mind these numbers are corrected for altitude.
The baseline was 679/685 rwhp from back in December. This was a rich tune, with conservative timing.
After cleaning the air model up, the numbers were 685/689. Nearly identical.
Once the car cooled down, we pumped the last gallon of 91 octane out (couldn't have planned that better) and poured in 10 gallons of E85 (vial tested at 85%).
At the same boost 115+ more HP and 100+ more torque. Pretty impressive.
I ran E85 for almost two years before moving out to Peyton, which had no stations nearby. Within the last few months, about 5 more stations with E85 popped up... one on my way to work each day, so switching back was a no-brainer.
We tried to run more boost, but I was getting misfires. Lito's questioning the gap, which I'm pretty sure was set to .032" (stock Motorcraft plugs), but I'm not 100% sure. Dyno operator seemed to think it was spark blowout, too. It definitely wasn't too rich. I'll probably post another thread about that, after I do some more reading.
Here's a graph with the two runs back-to-back. 91 octane is in blue, E85 is in green. Should be pretty convincing for anyone who's on the fence about switching....
