It took E85 to do it. The other barn-burners needed E85, meth, or race gas to get to this level.
Myself I'm interested in pump gas results. Guess I'll have to see what I can find for reference besides my own data points.
My hypothesis at this point is that small hotsides do very well with high octane, allowing quick spool and avoiding pulled timing on top.
Of course I'm not running a 7cm^2 hotside, which is why I think the 10cm^2 hotside with a free-flowing exhaust might make a statement on pump.
