574 Reaper Install
« on: February 12, 2018, 07:37:24 AM »
I just finished a complete Feuling Camchest upgrade with 574 cams, oil pump, lifters etc... I have a Screamin Eagle Stage I air cleaner, D&D Fatcat exhaust and a SERT. The Dyno printout shows 99.6HP and 106.3 Torque. I am thinking about getting some head work done but most of my research shows minimal gain based on my current numbers. Does anyone have any experience with a similier setup and have some headwork done? If so, which shop did the heads and what is the output? Its on a 103" 2012 Ultra Classic.

Thatís very impressive.
My buddy had an 09 96Ē Ultra and a mechanic friend of his installed those along with true duals, and a Cobra Fi2000 piggyback thingy.
My 103Ē SGS romped on him so easily it wasnít funny, and I know with my Fuel Moto PV2 map it wasnít putting out anything even close to your numbers. Maybe if he got it properly tuned?
Thanks

Dene - that's way too much cam for a 96...that thing must be a turd especially without a real tune   :turd:

Mike - headwork will make decent gains but what you likely need more than anything is more compression. Several good head porters on here and if heads are removed I'd have them milled and run a thinner than stock head gasket. .030 seems to work the best

It was more than a turd. I canít believe the mechanic recommended those cams in a stock 96 when he knew it will also be a two-up bike most of the time.

I can't either - that is mechanical malpractice at its finest  :down: :down:

If the guy likes Fueling cams they have a couple smaller ones that would much more at home in a stock motor. In defense of the not-so-bright mechanic I believe Fueling's website advocates that cam as a good bolt-in choice  :nix:...smh

Springer82, I sent you a PM but you inbox is full.

Thanks for the input fellas, I have already emailed WFO Larry to see about getting some head work done. I will look into the .30 gasket as well. What is the norm for milling the heads? How much do you take off?

I'd honestly discuss that with Larry. Tell him what your running, and he'll help you get the compression where it needs to be. Larry will give you good results.

You made a good choice. Ask Larry about the .30 gasket. Some are better then others!  :hyst:
Best of luck to ya. Enjoy your new ride.

headwork would be nice......but you need to bring up the static CR to 10.5 to see any improvement below 2,800........the 525 and a .030 would have been a better choice.......could also do a +4 cam gear

ill tell you one thing........set up properly there's is TONS under the curve and i know these cams just keep pulling. i rode 2 and built 2(543/574)...probably the smoothest curve i've ridden......i know the 543 @ 10.5 with a good 2/1 pipe works very well for a midrange type ride, 2700+.and it'll pull till the heads run out. tis why they call it the "freeway flyer..

last one i just did at the shop we recycled the power duals and TBR muffs....".....the 574 has more top than the 543 but needs a proper setup to gain any bottom. i did a 103 and a 110 with the 543......i used the SE 110 jugs/10.5/.030 and MVA heads just last week......these cams want compression.

i'm putting the 518 evo in my new built 80" '95 cop bike........

PS....my guy doesn't shift much above 4.500....stayed with the stock throttle body and went up one size o the injectors injectors.............you could also drop the sprocket if top speed ain't your thing.

Easy way to make Larry's headwork shine with that cam is add the 110" drop on kit ;)
