I have been made aware that the new Stage III upgrade kit is available with a big torque SE-585 cam.

Does anyone have any familiarity or information with/about this cam, and how would this compare to the SE-259E that comes with the same kit as well as the Stage IV kit.

 

im looking at the 2015 screaming eagle book and see no such cam. so idk there is a S & S 585 cam

 

The SE 585s are a new release, specs: Int .585 234* 18/36 Ex .585 240* 47/13 looks to be a better cam IMO than the 259E.

 

SE585 lift @ valve intake/exhaust .584"/.584".Duration @ .053 intake/exhaust. Intake 18 BTDC/ 36 ATDC. TDC lift @ valve intake/exhaust .178"/.142"

 

According to S&S:
585: Designed for 88 to 95 CID engines with compression ratios from 9.7:1 to 10.5:1 and 100 to 124 CID engines from 9:1 to 10:1 compression. Provides massive horsepower and torque increases starting at 3000rpm and holds steady all the way to redline. 3500-6000 rpm for 88" - 103" engines and 2500-5500 for larger engines.

 

What's throwing me off is the new SE catalog says its capable of making 88HP and 100ft-lbs of torque....

I have a Dyno from a 2014 SG with the Stage III that has the 259E cam and it shows 100.41HP with 111.73 ft/lbs of torque.

So my confusion is if its a big-torque cam, why does is have 12HP and 11ft-lbs of torque less than the 259E???

 

Retrop.... this is not an S&S cam, it is a new HD cam...., and included in their new Stage III kits, 92500023 and 92500028

 

 

I've heard some rumors about this cam - but looking as those crappy catalog curves, it doesn't seem like a huge improvement over stock.

Word on the street was it's a cam that HD can sell you in good conscience to provide improvement over the 103HO cam - instead of dropping coin on a 255.

I'm anxiously waiting dyno graphs on this one. My local dealership is doing a series of R&D builds with these cams - can't wait to spend money on it.....

 

It may be better than 255s but ya can do much better with an aftermarket cam and matching proper headwork.
