Recently completed some more dyno tuneups with 05/04/03 F7s. Several
have proven to be what I call “hot” F7s–very low fuel flow and
apparently advanced ignition timing. The latest, most powerful
yet (fitted with a 2.5 degree key but otherwise stock) made 149.5 HP,
with a drag-stingy 95 lb/hr fuel flow at 43 psi rail pressure! And this
was a long hot dyno run. I’ve got about three of these on a disc. I
will try to post a Hot F7 gallery tomorrow including one we tested with
a “thing” silencer.
Then hopefully this week we will have Mach Z numbers to post.
