Limiting factor with this I believe would be the cylinder pressures
The unopened motor may hit its theoretical peak cylinder pressure on 98 even, so changing to e85 might not do a great deal power wise
E85 is good for lifting the charge density of the air fuel mixture, so this means more timing or boost can be added at any given point to make more power. If you're cylinder pressures are already maxed out, then no amount of changing fuel etc will improve this.
In Justin's case, e85 might only allow a little more timing which will still be good but maybe not as great a jump as say a factory turbocharged motor switching to e85
However - what e85 may do in Justin's case is shift the peak torque point down the rev range, and thus make it more of a torque monster earlier, due to the ability to theoretically increase timing in the lower rev range on e85.
The other important thing to remember here is the additional torque this thing will pull. Whilst it may make say 300kw atw, it will pull alot harder than a 2.0litre or 2.5 making 300atw because of how it makes the power
Either way you cut it, this will be one special machine
