Bill has a Mustang dyno so that's pretty decent. This isn't a Corvette forum bro how much hp did it make at the wheels. No one cares what u converted it to that's gay.
Im betting it can make it on straight 93 but Bill likes to add Boostane for good measure but I doubt with a ported blower and cams that it needs it to make 900 whp. PBD has done that several times with Whipple blowers on 93 octane. Torque im assuming is around 750 which is decent.
Last year I seen a GT500 with a big Kenny Bell put down 950 whp on Bills Mustang dyno on straight 93 octane so its definitely possible without Boostane or Torco.
