I drove the two hours north to Phoenix. I just did two pulls. The first one was 15 minutes after I pulled into the shop. 929/975 or so. We then waited 20 minutes and got her to 955/1010 . Happy with the torque. Still pulling a bit of timing.

stroker 426 running E85 and 15 pounds of boost. I need a larger super charger as it spins to much above 6200 rpm and the horsepower goes down.

I see that the power is not continuing to climb after about 5500. Likely just too much heat due to all the factors. Interchiller could be an answer to keeping the timing where it needs to be and give you a little needed artificial DA.

Maybe give her a little more fuel. I had them hook up the sniffer. 12.1/14.7 is a lambda of .82. The gentleman stated your dash would read lower. Yes it will because it is on a stoich of 13.85 and not 14.7. It reads 11.2/13.85 is .81. Makes sense as you run a little richer by the bung even though there are no cats for the pull. I think on a positive displacement blower .78 is where I should be. I may add two percent on my handheld. Also she is at 23 degrees timing. I may put that back just one degree. The torque though is not a blip. It is strong all the way through. Good luck with your second day there on the different fuel!

Supercharger is probably an intake restriction on that big motor.

I would't touch anything on that tune unless you are advised to.

My wife reminded me that the large computer screen in front of us read 200 mph while dynoing in 6th and it almost felt like the rpms of the engine were slowing between 6000 and 6500 rpm. The computer screen would not go 1 mph over 200. Maybe I over sped the Dyno in 6th?

When mine passed 200 on the dyno it maxed out. 205mph I think. We did the rest in 5th. Showed a bit lower number but dyno is just for tuning.
