Default 02 ss dyno chart e85 d1sc
This is my dyno chart from Wichita Dyno just got the car back couple days ago. Running e85 its making good power and drives like stock untill you get on it. Car is running out of injector up top. Car has forged bottom end, stock ported heads, stock ported tb, full exhaust, 12 bolt 3.73, spec 3, twin pumps bigger lines boost reference regulator and aftermarket rails with 60lb injectors.






Here's the car

Did you have any numbers before the e-85? Just curious to see power gains from 93octane to e-85? I think your going to need a driver box and some 96lb low impedence injectors.

When I did the procharger i also switch over to e85 so I don't have any before numbers. I don't take the car much over 5000 rpm untill I get bigger injectors.

Is this a d1-sc? 465ft/lbs at 3000rpm is not bad.

Yes it is a d1-sc, I was surprise at the torque the car made thought it would make more hp the tq. This is my first FI setup so far I am loving it. I was always a nitrous guy untill now lol.

Isn't that really lean considering E85 stoich is (9.265:1) and max power afr would be (6.975:1)? That 13.5 would be kinda lean for a gas engine with stoich being 14.7 and max power at 12.5 or lower for power adder cars?

That chart is on the gasoline scale.
.75 lambda IS 6.975:1 AFR.

so .93 lambda (13.5 Gas AFR) is 8.61645, so yes it is lean at max power.
