Bench racing is bench racing. Come in swingin' a big dick, you're not going to go unchallenged. Not worth getting bent about... try taking this to harley tech talk and see how you fare. :-)

Put the bike on a Dynojet dyno and compare. Those numbers are higher than the Harley numbers listed in the catalog, which are "crank" numbers. Probably STD vs SAE. The "standart" is SAE, Smoothing 5. STD numbers are always higher.

Hey, if the bike runs great and makes you happy, that's all that counts. :-)

Thanks, had to look up STD/SAE dyno differences since this is all new to me. Found this:
http://www.hdforums.com/forum/engine...yno-sheet.html

So at a 2.6% difference, HP/TQ is down-adjusted to 117.7/115.5, but the bike does run great, which is all I care about, the numbers be damned...

If you look closely at the dyno sheet in the lower corner it say STD correction, not SAE, so yes, it will have a little higher numbers.

I suppose you're right here. Who really cares about the number, fastest to finish line wins.

I havent been super happy with my stage IV, i have the 260 cam. Considering going to ta Tman 660 or something but for now I've just been beating the daylights out of this motor without breaking anything yet.

A few brief points:

1. The OP has a much healthier and stronger bike that will be a bunch of fun to ride and he is happy, which is all that really matters!

2. Seacoast HD = Home of the "Happiest Dyno in the US".
The OP can only post the sheet he has and that happens to be from Seacost HD, I've seen multiple sheets from Seacoast on various forums and they all seem to be ~ 10% higher then one would expect for the specific combo and all of the owners say their bikes run great which is the key regardless of the numbers.

3. Repeat item #1 above.

Mine was done at seacoast also, i really can't complain about any of the service work there. The bike is very fun to ride, but with the 260 cam i ride the bike over 3400 rpm a lot of the time. I just want some more torque down low, considered swapping the front pulley out but thats almost as much work as a cam swap.

The bike will be going to seacoast choppers right down the road for further engine work when the time comes. He uses T-mann, tunes with a dynojet, uses mostly D&D boarzilla exhaust.

Not much of a website http://www.seacoastchoppers.com/
