Here are some results from a TW-555 cam install we just did on a customers 103" Power Pak Ultra Limited. This bike has our Jackpot 2/1/2 head pipe, Jackpot Dyno Tuned mufflers, FM Stage 1 air cleaner and was tuned with a Dynojet PC-V. We installed the Wood TW-555 cams and used our FM Quick install pushrods along with a full dyno tune. The TW-555 is an excellent bolt in cam for the factory 103", we had very good conditions for tuning and final numbers were 98Hp/109Tq, very impressive for a stock 103 with exhaust, cams, and tuning. In fact this combination made the best overall torque we have seen on a factory 103 with a cam swap to date.. Here are the final results........

 

Jamie,

Does the 103 power pack have the Stage II high compression pistons? Do you have the tq/hp number for stock 103? Really impressive numbers for a 103!

 

Impressive indeed.

 

what did it dyno stock?

 

That is exactly what I would like to do with my 10 FLHTK. I am in process of installing the Jackpot 2 ½ head pipe now then 4” Jackpot up slash mufflers. Cams, A/C & tune to follow as time and funds permit. Those are impressive stats. My question is how do squeeze 2 more HP to have the 100 HP bragging rights?
Thanks, David in Ohio

 

How much higher is that than the 103" with the SE255 cams?

 

You could have 2 Clydesdale horses pulling your bike and you would be right at 100 HP

Yo, Chief
aint you ever talked to a fisherman?

 

The 103 Power Pak comes with flat top pistons, and these bikes generally make in the range of 69Hp/86Tq bone stock

 

Dyno with a strong tail wind....or shift to fifth gear for the pull....
