Correction factor of 1.07/1

89 octane fuel
32 degress total advance
All marine accessories and pumps were in place and operating during the runs including the stock flame arrestor, and per Tom Earhart's info, the dyno headers used perform very similar to the Lightning headers on the boat. A last pull was made without the flame arrestor to see if there was any difference in performance. Horsepower was EXACTLY THE SAME with the stock flame arrestor removed.

It should be added that we didn't run just a blank carb for the last pull, we installed (duct tape eh?? LOL!!) a velocity stack. Cool looking piece, but no help!!! The motor looked faster though.:cool:

Crazyhorse 04-13-2002 11:08 PM

Yeah, well, the point to the flame arrestor thing is that it don't necessarily gotta look cool to do an ok job. It was chrome though, wasn't it?

Waterfoul 04-13-2002 11:13 PM

I'm tellin ya, chrome adds 5 mph at least!!!!!!!

Crazyhorse 04-13-2002 11:32 PM

Yeah, but if no one can see it does the chrome really make it faster? Kinda like the tree that falls when no one sees it. Does it make noise if no one hears it? Drugs, where'd I put my drugs?

Super V 04-13-2002 11:33 PM

Thanks for all the hard work Crazyhorse Dyno Waterfoul Kaama.That dog hunts!

Crazyhorse 04-13-2002 11:36 PM

Yeah, it ran ok. It was cool. That sucker pulls hard in the midrange, doesn't it?

Super V 04-13-2002 11:48 PM

Super V 04-14-2002 12:05 AM

It should be a grin!
