Nice. I'm going to get one...........soon.

[BlueThunder]

Very impressive!  Would this also work well with ported heads, and maybe 103 down the road?

[mike 120]

I sure hope it will work in a 103, have one going in a 113 with 9.6 comp and 110 CVO heads with new guides and valve job, hopefully will have strong torque in lower rpm range

I'm thinking real hard about putting one in my CVO 110.  I'm not sure if I need to increase compression first though.   

[Unbalanced]

Spoke to Wes at Cycle Rama about using this cam in a 107 and he said up to 10.3 to 1 would work well with the cam.

Bolt in the CR575 in your 110, leave the heads on, get a good tune and go.
With this cam as a bolt in for a 110, have repeatedly achieved high teens TQ and over 100 HP SAE with good left side "usable" power.

Here's one that crossed 120 ft lbs.

Heres another in a 110 cvo convertible, Rinehart 2 into 1,  Comparison from stock to cam/pipe upgrade, got the cams from Herko

[BlueThunder]

In a 96" with stock heads and compression, can you run the CR575 with the stock lifters and pushrods?

Yes, standard base circle on this cam.  I re-used the stock pushrods and lifters on the SE bike as well

Have an update on my CR575 cam install, 4.065X4.375,(SE pistons cut to flat tops) CVO 110 heads with 100.8cc chambers, 0 deck, 0.030HG did a ccp numbers are 195 each cylinder.Had Wes install new guides, a valve job and manual comp releases, very quiet running.

That is a killer curve for just a cam swap,I know Brian liked the ones you put in his CVO Street glide,I spent a fortune on my 95 to get numbers in that range.
Looks like alot of bang for the buck.

Mike 120, do you have a dyno chart? very interested in that cam in a 113".

[mike 120]

Deye, unfortunately no, just put it together last week and we are in the middle of a blizzard here. I'm thinking if it works well in the 110 with 9.3 comp, should be stout in a 113 with about 9.7, like I mentioned earlier it cranks 195 and fires right up cold without using the releases and runs very quiet.

What are the specs on this cam? Those numbers look very good for a basically stock engine and I would like to know more about it.

Is this a bolt in for 103 with stock HD heads?

[fatboy]

What about a stock 88".... with no head work.

[Herko]

Is this a bolt in for 103 with stock HD heads?

Yes, if it's a 103 with 06 or newer heads.

[Herko]

What about a stock 88".... with no head work.

It has .575 intake lift. Requires 06 or newer stock heads or 99-05 heads prepped for 575 lift.

Would the cam chest and rocker boxes need to be clearanced in 99-05 cases?

  Just wanting to follow thread...........

[Herko]

Would the cam chest and rocker boxes need to be clearanced in 99-05 cases?

Zach

The earlier cases would very likely need to be clearanced for a .575 lift intake lobe.
The later cases have more clearance in the scalloped area for the intake lobes.
Always perform at least a visual check on all cases.
Rocker boxes largely depend on the springs being used.
With beehives...no.
