In Arizona, it is e-54, and for street driving it should fine based upon your build.My chip is setup for E85 and 22/24 boost. Does that mean I need to turn down boost to compensate for E51? I bought the car with E85 setup.
I'm sure he means the timing is 24/22 for Eric's E85 chip.I dont understand why the chip would only be for 22 to 24 psi. E85 can handle way more. With that said, E51 will handle that boost and timing, but will be richer. You can actually turn the boost up if you wanted to.
This has been my experience as well. With 80lb injectors and e85 I can hit about 24psi, with an ~e50 mix I've gone as high as 30psi and 19 degrees of timing. The only thing that scares me away from running that high all the time is an occasional blip of knock, which appears to be false, from either the constant wheel spin or something metal hitting on initial acceleration.This E51 pump is awesome, we have E85, E30 and E15 at a Woodman's 2 miles away from me so I blend. I've been running E50 in both of my other sports cars for two years now, one is my Talon running 28psi and 17 degrees timing with an intercooler pushing 140 temps at high boost.
There's not a big difference after E50 in power and detonation reduction vs E85 but a nice difference in injector duty cycle. I'll be running my newest GN engine on E50 and alky on 80lbs Inj with plenty of headroom room at 50psi base pressure.
