alky and 90 octane

[86SS86LS]

The local gas station has 90 octane (87 octane w/10% ethanol). Can I run this with alky and not have any problems with knock?

Sure. You can run 87 and not have any problems with knock. It is all in the tune. Will you be able to run 25 pounds? Most likely not. 20? Probably so. Start off slow and up the boost as the knock allows. I run 91 because that is all they sell around my house so that's what I have it tuned for. I, at the moment, have maxed out my turbo and am tuning on the timing.

Just be careful as there is marginal room for error...

90

I have ran 25 pounds of Boost with 23* degrees of timing on 90 and Alky. Using Razors kit one nozzle.

Keep in mind this is in cool temps with no humidity, approx 45-50 degrees.
