Do you have any on track experience running consistently with an E40% mix.

When I send Jeni out in the car to be on track she gets the car between 15-30% but when I was running with Vaughn and the GTD at CMP, I turned it up to 40% to pass him. Where I got greedy was with Billy Johnson driving the GTD, I added another few gallons and it hit 47% which ran like a raped-ape for a few laps til he out-braked me going into turn-1. What I think made the car hiccup was chasing him down and catching very little clean air behind him and at this point I had not realized the data which came a month later at Road Atlanta to short-shift the car.
Dan, E30% is a really safe place to be and it fulfills all the needed safety parameters for beating on the engine without any loss of power. I have also considered adding a BAP to spin the low side harder when the car is running Spicy, just to add measure.
