My single engine hopped up 525SC/560ish hp Pantera used more fuel at cruise speeds than my 32 AT with 502mpi's. The Pantera averaged about 1.25mpg and the AT averages about 1.5mpg.

598ci N/A about 750hp

I cruise at 3500rpm and burn about 25gph and cruise at 55mph. So about 2.2mpg.

Of course the throttle doesnt stay in that position for long, and I can assure you, it gets thirsty at 6000rpm.

Good plan. For some reason I thought you had some big engines in your Cafe. I guess my memory sucks!!

What is your WFO speed?

I used to...that's where I learned my lesson.

WFO speed:...I want to say 70, but I'd be lying.
69's a fine number anyway.

25 Daytona, blown 509 / 900. Cruise at 3500 nets 75mph and 1.5mpg. 6000 nets 110 and just barely 1mpg

powerplay 25 with twin 300 xs's
cruising speed: 60 liters/hours
top speed : ???? i don't care

LMAO!!!!! Nice seeing you last week.


For me:
38 straight-bottom Top Gun, big cubic inch N/A's (800HP) with #6's.

I figured out last season that I average .88 mpg at cruise. 4000 rpm's is right around 60-62 depending on water conditions.

WOT.....don't want to know.

I'll throw an odd-ball in here, 32' Pachanga, 2 x 330 mercruisers/alpha, timing turned up a bit, performer intakes, stock carbs, older motors but healthy, 34 mph @ 2600 2.6 mpg WOT 63-65 at around 4700

:boat :

2mpg at 114mph
