Just did the 103 upgrade on 07 Ultra with SE 10.5:1 pistons mild ported heads and 50MM TB have woods tw555 cams fueling lifters FM adj push rods. Tuner told me my pipe is killing it (freedom performance 2 into 1) so switching to VH pro pipe (or d&d if I find a good deal on one) and that I need a higher lift cam like the SE 259e but I don't want to lose the low end TQ so any opinions on the woods TW-7 cam or keep the 555's ??

 

going to the 777 may not matter if the pipes are no good, a waste of money new pipes instead of cams at be the answer Could be a problem with install of cams. Off a tooth?
Sumping. Oil pump o ring get changed ?

 

Your tuner must work for harley to want you change to a se cam, cause I can't think of any one else that every use a se cam for power, the 555 is better than that cam. If you need more I would go with the 777 or the 888. Just my opinion tho

 

looks like both have fuel moto b heads

 

You have an 07, cursed with too high gearing. Get an evolution-industries 49 tooth clutch basket. No need to change cams.......lower gearing will liven up that barge,you'll love it.

 

A. Did your head porter change Springs??
B. What size Head Gasket ?
C. What compression ratio ?
D. What's your CCP ?
E. What is your tuner tuning with?

 

I think I would look at other cams?

 

Defiantly not enough info to make any sugestions but higher lift isn't the answer. I'd guess a larger throttle body may be a bigger boost than a different cam??

 

I kinda wondering what the tw-7 will get you, from what you already have. It will definitely shift the power band further north.
If you go to fuel Moto's web page. Most of their dyno sheets they display with ported heads are utilizing the 777 cam.
This suggests to me that Fuel Moto loves to advertise the power made.....but what are you leaving on the table????

 

Thanks for all the replies, here's a little more info Heads (new w/acr's) basic cleaning and smoothing runners and chambers for better flow 1.9in 1.5ex stock springs, SE 10.5 piston factory .04? head gasket as recommended by builder, SE 50mm TB, woods 555 cam, fueling lifters, FM push rods, stage 1 AC, SE tuner, freedom union 2 / 1 pipe. tuner said should be over 100hp and my pipe choice was the problem and higher lift cam would work better with this combo. Still need to do a compression check to get the real ratio. My first thought was to check the O rings on the oil pump to make sure they seated right and change to woods lifters and maybe go to a VH pro-pipe, I would think the 555's would be fine if not the 777 looks like a better choice. I posted a copy of dyno sheet.
I changed the front pulley last year to a 30-T.
