Oh my! This injection is awesome.
Throttle response is instant and wicked. Be careful doing the burn out. I hit the rev limiter once when I hit it too hard.
The bottom line:
1.25 sixty foot 5.76 at 118 mph at the 1/8 mile mark, 9.12 at 145 mph at the 1/4 mile finish line.
The air was mineshaft, about -600 to -1000 ft density altitude, but with the sunshine the track was hooking. In fact I need to do more work to calm the wheel stand. It tripped the sixty foot timers with the rear tires everytime I smacked the launch (footbrake). The 1.25 was a quick roll-on of the throttle. I did some things to try and stop it, but I need to do more.

I think you have a 8 second timeslip waiting.... How much do you think it will differ between the alky and the E85??

That is awesome Jim. I was waiting to here about your track test with the toilets as I am going to be running them for the first time also soon.

Yes, this was on race alky (methanol). I plan to tune the system with the fuel it was intended and they have experience with. That way we know what the motor likes for a tune. Then I will recalibrate for E-85, maybe May? I need to get summer blend E-85 in the 82-85% ethanol range for my 13.5 CR (IMO). The last pass I was able to get 12.3 A/F ratio on the LM-1 wideband sensor (gasoline scale, actual Lambda=0.837, actual A/F=5.35)
I think the E-85 will be 0.10 slower than race alky. I am told that the race alky will not change ET as much with the weather going from spring to summer heat. So the difference between alky and gasoline will be greater in the summer. I am impressed with the alky, but I like the economy of the E-85. It is between alky and gas in performance, cooling, amount used, etc. But the E-85 at less than $2.00/gallon is the cheapo way to run high compression (13.5).
Although right now, the local track is selling alky for $3.95/gallon or $190 to fill your drum with 55 gallons ($3.45/gallon). I got a lead on a MD supplier for $145/drum ($2.64/gallon). I expect alky (methanol) to get cheaper as the summer comes (industrial reasons). If it gets close to $100/drum, I may run it longer...
I will try to get to Pittsburgh for the CC event.

Way to Fly Jim !!! What nozzles and return pill were you using?? James Monroe provided 37 nozzles for my Terminator and said to start with a 87 pill. Although i have the black gear pump which may affect the fuel curve??? Hope to learn from your experience so please keep posting Cheers, Arnie
