A modern EFI system would tear any old MFi system a new one. But it's old skool kool!
The engine driven pump alone robs HP(parasitic loss) whereas the modern stuff all runs of en electric fuel pump.That require a stout charging system,which is a parasitic loss in itself,but it's not nearly the drag one of those old pumps would create. Most likely,this Hilborn setup is aimed more at alcohol or nitro fuels. Somewhere there's probably an old top fuel bike that didn't make it down the return road
If I had a spare grand that would be mine.Tuning horrors and all. Thats some sexy machinery right yonder...
