Given the fairly significant increase in power for the L83 on E85, we thought it would be worthwhile to go back and retest the acceleration performance on E85 fuel.
As expected from the chassis dynamometer data, the performance did improve.
Impressive performance numbers for a stock 5300+ lbs truck (200+ driver and a full tank of fuel so we were over 5600 lbs).
I did two runs on E85. They were virtually identical in performance so I didn't do any more runs since the data was so repeatable.
0-60 mph was a best of 6.96 seconds (6.97 on the run displayed in the attached graph). This was an improvement of 0.5 seconds over the best gasoline run.
1/4 elapsed time dropped to 15.51 seconds at 93.5 mph, for an improvement of 0.4 seconds and 2.7 mph.
