Have a 09 FLHT
I am thinking of changing stock cams to the 255 cams.
What are the REAL gains gotton from the change (HP & Torque,0-60 & or 1/4 mile times)
we have a 96 running, d and d boss, or fat cat, 203 cams, s.e.r.t., and stg 1 a/c
just shy of 94 hp and 103 trq
I like the looks of that!
I would choose the 204 instead of the 203 but just me.
I will add if that was had from a stock head and stock compression 96ci with 203's you did good! nice job!
EDIT: to say the D&D was the diff in 8-10 hp and 2-5 tq. on your 203 build wouldnt you say. service guy? that just shows you what a good pipe can do for the build.
then there is the x-tra tq. under the curve that will be felt @ 2300 rpm and out to 5500 rpm.
again nice job!
yes sir, stock heads and compression, 204s are a good choice to though, over all though we were happy with how it turned out.
and yes, i took 3 dyno sheets and overlaped all of them , all of them had the same set up cams, a/c tuner and such minus the pipes.
rush slips only 2 in baffle gave us 83.6hp 96.95 trq
v h 2.5 inch baffle 85hp 99 trq
fat cat was the numbers i alredy gave,
we are about to do another 203 and fat cat combo but with a heavy breather, ill let you know how it comes out
103", SE Intake, SE Exhaust, new 259 cams:
96hp, 115 tq
I am still trying to find a way to scan my dyno sheet. The torque 'curve' isn't really a curve. Basically stays within 10ft/lbs from 2500rpm through 6-7000rpms.
Take a look at these new cams, they're a welcome suggestion from my HD tech.
