Cam choice that suits me?

    Can anyone reccommend a good cam for my 2008 CVO Softail Springer? It is currently running a se-260 cam. I find that it kicks in around 3000 to 3200 rpm and then pulls like a train. I would like it to kick in earlier as I like to reduce the rear tyre life when Im in the mood! I ride 2 up maybe 30% of the time. Stage 4 113 cube. Is anyone running a similar set up?

     

    Cheers

    What is the compression set at?

    10.5:1

    Have a look at specs for s&s 585, wood 555 and andrews 54. Se 211 is another. Each of these cams would work but 10.5:1 is nearing the highest compression you'd want to run with these cams.

    Have you ever done a cranking pressure check? If so how many pound cranking pressure?

    Thanks fatbat I will look into these cams. I haven't done a crank pressure test Krash.

    Unless you check your cranking comp your only going off theory on the ratio, best to check before you make a call on what cam to buy.....next.

    The Cam's supplied in the HD stage 4 kits are a bad choice for the average street rider .
    I have a new set of Tman TR625's here ( for sale !)  that with a good tune, would transform your 113.
    Do a search on them for info.
    I've seen them work in a 95" and all the way up to 124"

    The only cam from Fatbats choice I would even consider is the S&S585.

    fckn nice ride.....
    i'm looking at cams also, and possibly get Hoody to do the heads.
    currently have 97 hp and 115 tq,.
    After another 15 hp and 15 tq?????? and maintain good ride-ability etc.

    Depends on what lift your heads can handle and what your ccp is. If doing cams only you need to know that.
    585's are an awesome cam if you still have stock springs.

    Talked to more people today, trying to find out the best bang for your $.
    More money than what i really want to spend, but....this might be the best option.
    SE 260 cams, 58 throttlebody, 10.5 pistons, 4.9 injectors, heads by Hoody, then a good tune.

    just have the to find the $$$$$

    my answer above was for the original poster but it applies to you too Ralph!

    Yes $$ but you get what you pay for!

    Your 260 cam should work well. Maybe look at the exhaust design as to why there is a "powerband"..... Even an off tune.

    By LATE BUILDER you mean higher rpm torque I guess. Give it 10.7. It doesn't matter, what most folk fail to see is it is impossible to acheive max torque anyway over about 85ft. One never can find a hill steep enough to hold the bike at 100% throttle and have the engine not gaining rpm. Here is one we prepared earlier. 110 CVO. 62 TBody. 260 cams. 10.65 comp and Fatcat exh [URL=http://s1229.photobucket.com/user/Nev140/media/img009.jpg.html][/URL]

    Thanks for posting the sheet. Can't argue with that !
    Looking at it though, you can see why the original poster would say it "kicks in" by 3200.
    Can't say much more without knowing his bike's state of tune.
    I guess we all have different riding styles as well, and prefer different power delivery.

    You won't be able to ride it like the dyno sheet, WOT with a 62mm TB at 3000rpm,. Riding the bike is a whole different story. Thats why I say look at the exhaust and tune, rideability is not torque or throttle response.

    Looks like a good combination of parts and tune for that dyno sheet using the se260 cams.

    But if the op is simply wanting more torque down lower at minimal cost/effort than his current setup provides, he may not want to change out the throttle body, some head work, compression increase, exhaust etc.

    If he's only prepared to change the cams and have it retuned to bring higher torque down lower in the rev range, what would be a good cam for this objective?

    It wasn't that long ago that another bloke on here bought a brand new Harley, had it fitted with a stage 4 kit and he also hated the way it rode with a power band up too high for common street use. Sadly I think be pulled it apart and went back to square 1.

    A 2:2 exh with balance pipe like stock type headers will give more power under 2750rpm. More compression would help the 260's low down. Could use 258 cams but will waste all that lift. I don't know what the RB system is like. The ones I have seen are biased towards top end power. WHAT IS THE TUNE LIKE? If it is a stock ecu download then just tuning it will help a lot. The Tman spec has a 41 inlet close, to me waay too early for 10.5 comp.

    At 10.5 comp a 50 close cam will do 195psi on my snap on gauge. 200+ is not necessarily good. Each to their own.

    if you look in plug hole and dont see crowned piston and only flat top , you may have 9.6 comp , with .040 head gasket , worth a look , some of work i have seen latterly charged for and not done , bit of worry , earlier some asked , comp test eng properly , look it up how to do it , not from mates head , , and check readings with quality gauge , cheers
