While these numbers are great, I think everyone here is getting too excited and ignoring that ethanol can't be used as an octane source unlike N55. This dyno run was with an E40 blend and at the cost of running extremely lean (dangerous). So effectively, those numbers are from a glory run.

It's still too soon to get excited is all I'm saying.

We're likely going to have to turn to something external like meth or TBI to further extend the fueling range.
