I bought a 2012 Flhtk with a stage 4 103 running Se 259 cams. Runs great from 3500 plus. Was looking at Andrews 57 cam to possibly move the torque band to more in the cruising range. Or will the compression be too high for this cam. Do mostly 2 up riding. Or is there another cam that will work better? Thanks

 

...is that a second Ultra? ...your sig says it's got 777's??

 

Yes. Just got this one.

 

57h would be step in wrong direction, cam spec very similar to the 259e

as much as the advertising by Andrews says 2200-5500rpm

keep in 4th or 5th

 

curious to what you are thinking there (on account of I have said 57H) ...the IVC and EVO happen earlier than the 259 and the LSA are quite different as well...??

 

Might try advancing the SE259 cams to bring the power in earlier.

I'm curious also... I was concerned that it would build too much compression down low. Looking at most dyno sheets the torque comes on way earlier, but none of the sheets on here are running 10.5-1 compression that I have seen.

 

10.5 on the 57 would give you about 205 ccp which would be on the brink of too much

 

the cam spec of 57 is very similar to 259e

57H
intake 18/46
exhaust 38/14

259e
intake 19/47
exhaust 58/12

 

not sure where you are getting your info on the 57h but straight out of the Andrews catalogue (as well as Bigboyz) it says...

Intake 18/38
Exhaust 46/14

I think you've swopped columns and rows there somewhere

(I think it's the SE585 that is quite similar to the 57H)
