SE 113" kit dynoed. Is something wrong?
Just dynoed Rocker with SE 113" kit including SE 110+ heads, SE-264cam, 50mm TB, SEST, heavy breather and V&H Indy 2 into 1 pipe.
Results: 117,5 rwhp and 119 ft-lb witch I think is normal for this kind of combo? BUT torque curve has quite big dip at 3-3,5K:
2500 - 100ftlb
3500 - 95ftlb
4500 - 119ftlb (max)
I think there is 10ftlb missing at 3.5K. AFR ratio is OK (about 13) all the way.
Any idea what could cause the dip? Pipe? Cam? Something else? I am sure SE did not plan this kit like this..

Pipe is V&H Indy Competition series 2 to 1.

What do you mean by ccp? Do not know the acronym.

it could be the tune causing the dip in the power. how good is the tuner that set up your bike?

Here in Finland there is not so much competence on SEST tuning. The AFR was first way too rich at 3-4K. We got that sorted out but it did not have any major effect to TQ curve dip. Sure it helped a bit.
It would be extremely intreresting to compare SEST map on some other SE 113" kitted bike.. With SEST base map (176NL-005) the dip was about 4ft-lb worse than it is now afer tune. VE tables where altered about 7-10 units down at 3-4K and on 40-100 throttle positions. From 4 to 5.5K VE tables where moved about 5 units up. Some minor changes was also done to AFR-map. Other than that SEST map is quite stock. Iddle richment by AFR table was also done.
Do you guys feel that is all about SEST tune to cure this? I am starting to think that combo with 50mm tb, V&H 2" tubes and SE-264 is not so good match at 3,5..
If someone has 113" kitted bike with SEST and somewhat close parts combination I would be more than happy to exchange maps and compare them...
EDIT: SEST map number

better then mine
Your numbers are better then mine and I'm running a 58ml TB with 266E cams with V&H Chrome Pro pipes and mine numbers are 115.83 HP 106.43 Torque. I'm taking her to a new tuner, not a happy camper. Now I fully understand when people talk about who to tune your bike.
