What kind of timing do you run WOT on E85? Could I afford to add more timing during WOT?
On a 98* day, made 810rwhp on 21lbs on 14* timing. I'm wondering if I could add more timing and make simular hp on less boost while still keeping the tune safe. Would 18 or 20* of timing be considered pushing it on my set-up?
365 LS2 Diamond Pistons, Callies Rods and Crank (stoke stroke)
Stock LS6 Heads
LS9 Gaskets
Comp 224/224 .588/.588 114lsa
#8 fuel line
100# injectors
2 Walbro high pressure intank pumps
Precision Billet T76GTS
3" DP that dumps 4ft later
Eboost 2

I think there is a guy with a GT88 right now running e85 on 28psi and 20* timing if not more IIRC. I think he may have used up to 24*. I'd start bumping it up 2* at a time. More timing will hit the tires harder and make the turbo spool faster and harder. Less timing or the same amount of timing and more boost is easier on the motor itself but will be less responsive. You have to find the happy medium and be happy with the performance yourself to know the answer to your question.
What is your compression ratio? I'm more surprised that the 76GTS is able to push 21psi with those cubes but I guess the stock LS6 heads are a bit of a restriction. Also that timing number isn't necessarily low either for E85...

I dont have copies of the dyno or details of the tune yet. Ill have to get back to ya.
I'm only shifting between 6000 and 6200rpm. Redline is set at 7200 I think.
