Hey guys, I was wondering if there’s a hp to Cubic inch that is average? I’m not too happy with the results of my build and think my numbers should be better. Could some of you experienced builders out there tell me if I’m correct and should be better? Listed below is what I have. Thanks in advance!

03 Night Train
S&S 98”, S&S cam plate & oil pump ( w/ upgraded hydraulic tensioners )
S&S 79cc Super Stock heads ( 10.6:1 cr ) about 201 ccp
S&S 52mm throttle body, S&S fuel rail kit with 5.2 or 5.3 injectors
Fueling 574 cams
Rinehart Crossbacks exhaust
Power Vision

Dynoed at SAE 96.66 HP and 100 Tq, I thought I would have been at least 110 or close, am I wrong to expect 110? Like I said, thanks for any replies!

I plan on posting once I get back to the house. It’s SAE but those numbers seem awful amd don’t know if it’s the cams or tune/tuner?

Posting your dyno sheet would be most helpful. There are differences in the systems used by tuners, STD or SAE.
Plus, not all dyno tuners are created equal. Some suck and some are very good.

Here's the dyno sheet

Im not chasing numbers but I expected to get over 100 hp and 110 or higher for torque which is what I care about, Im not really worried about hp as I dont take my bike to 5500-6000 rarely. I think its the cams and the tuner and doesnt a good tune take about 5 hours or so from what I hear, a buddy of mine wrks at the dealer where it was tuned and from what I hear he only spent at max 2hours or so.

With a flat top piston at 98" and 79cc head he is at an honest 10:1 and the cam has a late 46 intake closing. Proper timing settings and there would be no timing pulled.
Does put the whole tune in question however and if the timing was set wrong it would pull timing and totally blow any power and torque production

I have domed pistons ( 3.4 on spec sheet ) and as it may seem like I’m chasing numbers, I’m really not. It does run good and I’m happy with it, all I was saying is that I thought for sure my numbers would be higher than what they are. I think tuning has a lot to do with it and I’m looking into a different cam. I care about torque as that’s what I use, HP numbers dont really matter to me as I rarely get to 5k rpm or higher. I’m looking at the Red Shift 575, any experience with those? Thanks
