Base 1LT, non Z51, non NPP, factory all seasons at 25 PSI rear, 41 PSI fronts, front sway bar unhooked at the links, attack blue air filter and E30 fuel. Late in the afternoon, maybe 1000 DA with a 8mph headwind. No tune, no weight removal, no headers, factory cats etc, etc.

That's a nice pass with great trap speed. I should be going back to the drag strip pretty soon. I have the ported intake manifold, 87mm ported throttle body and the Halltech Cold Air Intake. What was the temperature?

Pretty great run you had. This is the best I've gotten back to back runs. I'm completely stock Z51 2LT 91 non ethanol and air temp was about 60. This winter I'm putting on Paragon track exhaust, throttle body, air filter and may get some drag radials.

E10 89 will typically outperform E0 91.
I'm not saying you should run 89, I'm just saying that's how badly E0 91 sucks.

Thank you for the kind words.. On your pass I would have expected a higher trap speed on a 60 degree day. Are you running in high altitude? Trap speed is a good indicator of horsepower levels considering the curb weight of our cars are less than 50 lbs apart. I ran with only 5 gallons of fuel in the tank, saving about 80 lbs along with another 10-15 lbs of odds and ends Add the curb weight difference and I ran close to 150 lbs lighter than your car with a full tank of gas. Hope that helps and good luck.

I'm in Minnesota and in lakes country that has a lot of non ethanol 91. I run that in all my seasonal things because you never know when your season may end. In the past when I've let ethanol fuel sit for several months it haunts me.

That makes sense as E15 88 octane made the 12:1 5.0 in my old F150 knock less and runs better in my Ecoboost Expedition, which they give it another point of octane for only 5% more ethanol than E10 87 octane. I wonder if E30 is around 100 octane as E85 is supposed to be ~106 no?
