this is my 1st time using a desktop dyno so this may be WAY off or close...or even right

i just don't know.

my figures are showing:

497 HP @ 6,000
488 ft lbs. @ 4,500
at the fly of course

if i'm right, congratz

if not, i pray i'll learn to run this thing correctly one day

Just by ear that looks like its about 350HP at the flywheel. Maybe a bit more, but just my .02.

good luck,
steve

Thanks luda, but there's no way. I was expecting 360 to 370 HP.

Anyone else?

I don't have Desktop Dyno, but both of you guys look to be 350-380 HP at the flywheel.
