Paul and Dan Cross came today, dyno’d Pauls newly acquired 04 F7 EFI
with reprogrammed ECU supposedly to 05 specs. This one made 144 w/
94-95 lb/hr no key. Made 150 w/ newest Bikeman F7 modified single I
have hanging on my pipe rack. D&D Y added a horse and a half to the
stock pipe (145.2) and 2 lb/ft torque. Then the D&D Y added a
couple of HP to the Bikeman mod stock single, to 152 and change
at higher revs 8100+ where fuel flow was dropping to 13/1 A/F. It
was still OK for 20 seconds WOT 93 octane, but Paul is going to
play it safe, get onother stock pipe to have modified for
dragracing at 152 HP, keep his stock pipe for trailriding at 145
HP. No Boondocker was needed and NO FUEL CHOKE ALLOWED. I never thought
to try the ethanol mode to see if we could have dropped the Bikeman/
D&D Y setup into the 12/1 range and 150 HP which could have been
Paul’s trail combo.
Tomorrow, Scott Lyons is coming in the afternoon with a more modded F7 with more stuff including Speedwerx single/ D&D Y.
Wednesday late afternoon, Sean Ray is bringing in a stock 04 F6
carbed, we may have a new F6 pipe from D&D by then that is
supposed to be good for some extra HP.
