Latest News about Hilborn from Mike Chilando & staff, Alkydigger:

“… Alkydigger has developed all the Hilborn Barrel Valves, Hoses, Nozzles, including a ½-20 Thread Sprint Car Nozzle with a drop in changeable jet to keep replacement costs down to $10 per change.    We are also going to take their (Hilborn) EFI 8 Stacker for the BB Chevy and reverse engineer it to become MFI using our barrel valve and nozzles.

We won’t let it die!  Thank you: Mike, Toni, & Shannon”

Excellent article in Alkydigger web site about adding toluene to gasoline for more octane:

The Alkydigger article indicates toluene has limitations as well.
