I had 204 in my 96ci FXDF and 254e in my 103ci FLTRX. Yes two different size bikes, but the 254e were a lot more easily tuned and pulled from idle to red line. I don’t have dyno print out, as went with a canned tune and never needed to touch it. 204 sounded great at idle and did pull hard. Exhaust also a critical component, so you must factor that in.
And there we have it, first hand experience, thanks for speaking up mate, the E is one of their later grinds as far as twin cams go, I remember when it came out and we was discussing cams for a 103 bagger on HTT and I brought it up, the OP looked it up and said it was described as a hot rod cam, intake close ain't the be all and end all of timing events, the cr570-2 is evidence of that, interesting.
The cycle Rama 570 cam’s intake close is at 32 degrees. It’s early which is why it produces lots of torque down low.
Yeah yeah, that's my point mate, that 570 runs out even with the early close, no expert but was told the exhaust timing has a lot to do with that, I'd still go the 204 over the E.
I’ll be interested to her how you go. I ended up going with an S&S 583 cam, and after a little over a year am considering if there is a better suited one for me ...
Toby I dunno if yours has been dyno tuned or not but this the sort of curves you could expect with that cam, it's not one for me but lots of people like it to all happen early.
Be nice to smooth out that dip at 3250rpm though. (not that I'm being picky!)
Just picked up the dyno sheet.
Do you think that would be the exhaust making that curve?
Them hp curves are similar aye.
