Depends on what kind of E85 you use. Pump fuel is a mixture that uses the dregs at the bottom of the gas tank. The leftover crap that they couldn't sell. Unfortunately, that 15-20% gasoline can cause detonation under the first ring land, and you get this:
And that really limits the amount of cylinder pressure you can build.
OTOH, a quality racing E85, like Sunoco E85-R, uses a high octane racing fuel, and the mixture is much more accurate. With this stuff, you can safely build a lot more cylinder pressure.
