See post #18

Buddy of mine just did a Hillside 107" build.
Numbers turned out to be:
103 HP
118 TQ

He's wondering why his HP number is low.
He's using the Screaming Eagle Stage 1 intake.
Rinehart True Duals.

Just throwing it out there.

 

not bad numbers for a 107 my HQs 107 is 109 hp 119 Tq with stock head pipe and thunder header slip on's

 

What cam?

 

Whatever Hillside provides with their 107" package.

 

I didn't realize he had just one combo. Can't speculate on the question that was asked about the HP number, without knowing the build.

 

Chris ~ without knowing more about the build, it's tuff to guess.

Heck, it could be dyno that is "stingy" and that's just what it is.

If the package was spec'd by Scott, and things were properly assembled, the tune would be a good place to start looking.

What year & model bike, what pipe, what cams, which (stage?) heads, compression, TB, injectors, ...???...

 

Seems within the appropriate range for a 107. It also might dyno at different numbers next month. It also would likely pull different numbers on a different dyno. If the bike is running well, he should enjoy the ride and quit stressing over the dyno sheets. Too many guys get too wrapped up over what numbers their bikes pull.

But I guess Hillside advertises 120/125 with this build, so I would be more than a little curious too.

 

How does the bike run?

 

Hard to say without knowing which stage heads, size of throttle body, cams, compression ratio, etc. With that said, I agree the hp seems low, but if your buddy were a stock throttle body...hmmm.

 

Hard to say without knowing the components and the compression. The pipes are probably holding it back some too.

I'd like to see the curves and the afr, but just looking at that horsepower number, it seems low for a 107. Torque ain't bad.
