It's a 24 tooth. I don't remember the Baisley style tooth count but they are 2:1 and don't see how that could work at all with a mismatch.

 

It's time for probably the hardest and possibly most controversial choice in the build...

Cam shaft selection.

I've been reading and rereading this post on cam numbers: https://www.hdforums.com/forum/engin...and-2-a.htmlin

The bike came to me with a Screaming Eagle 406 in it. I was happy with the way it ran but I would like to lower the RPM range a bit while taking advantage of the increased compression ratio and mild head work that's being done. It did OK off the line and when the cam came in it was noticeable, and pulled well.

I'd like something that comes in a little earlier but doesn't run out of steam too early.

I've compared the numbers on the SE406 to the Wood W6 and several other cams on the chart on the Nightrider web site. I'm concentrating on intake closing, lift, duration and lobe centers pretty much in that order.

Looking at some of the numbers I think the Redshift 560 should be between the 406 that I have and the Wood W6.

Looking at other numbers I'm afraid it may be too low of an RPM cam for what I have in mind. I'd like the power band to be from 1500/2000 up to 4500 or higher if possible.

Any input on the Redshift 560, or cam selection in general, is welcome.

 

Okay the cams you're looking at are all over the place.. The Redshift 560 cam is a real high-end camp and can do nothing for the bottom end... The 559 would be the better choice if you want to go with Redshift. Those 2 cams would require 10.4-10.7:1 comp.. Also I disagree with the Ultima crank... But that's your choice.. You're also going to need head work to accept the lift off anything over .530"... You need to be a little more specific of what you want out of this build our just let the shop that has everything all ready suggest a package for your build and good with it......

 

Thanks. I need to study the post on cam numbers more, I had interpreted that as a low to mid range cam.

I mentioned the SE406 because it's what I have to compare things to. I'd like to lower the RPM that it comes in a bit. I'm going on memory, if I had known the bike had an upgraded cam I would have made note of where the power was. I seem to remember it was around 3000 RPM and up. I felt it most when accelerating up on ramps.

I let myself be talked into the Ultima crank and justified it to myself with the thought that the shop is warrantying the build.
I hope to end up around 10.5:1 compression. We're starting with 10:1 pistons and the shop is doing head work, springs and are ready to clearance the case if need be for the cam I select.

I am clear that I want the power around 3000 RPM, freeway cruising speeds. That's what I'm trying to pick a cam for. The shop owner was talking about more top end cams and I told him the same thing.

As I mentioned in my prior post, I'd really like the power from 1500/2000 up to 4500 or higher if possible.

 

I don't think there's a cam out there that'll perform at 1500 or even 2000 maybe 2500 rpm if you're lucky but there's no real performance below them RPMs in an Evo.. If you're getting head work you'll be able to just about put in any cam you want and just make sure they match the compression to the cam that's all...

That SE406 cam was a high duration low lift cam that needed RPMs to get it going The w6 should come in around 2700 and go all the way up to 6,000 RPM It's a great cam.. They even make the high lift version the W6H if you're getting the head works you might as well go with that..

 

I won't get anywhere near a cam pickin' discussion but will tell you, the 406 you mention is actually an SE-1 or SEH-1 depending on manufacture date. They were the first and only SE cam offered by HD in the early Evo days and were made by Crane. They are great over 3200 and won't give up till the springs do but they are a terrible choice for a heavy bike. Main point being, almost anything you go with will be better on the low end than what you've been running.

 

Ah, I'd seen mention of the W6H but hadn't seen any specs. I need to search more. That RPM range would work, once I'm off the light and moving I'll just keep it spun up above 2700.

I did look at the specs again on the Redshift 359, it says it's 2200 to 6000. I can't find a Redshift 360 for sale, maybe they grind them when an order comes in.

Thanks for the help!

 

Thanks t150vej, I was typing my response to 98hotrodfatboy while you had posted yours.

I completely understand not getting involved in this type of discussion. I did mention it's probably controversial.
I appreciate the info on my present cam. It does have SEH-1 stamped on it, as well as 406. The chart on the Nightrider website doesn't list a SEH-1, it's listed as a 406.

 

I just tripped over my junk cam bucket few minutes ago and on top were 2 of those cams. Both are marked SEH-1 on the rear lobe and 0406 on the shoulder, who knew? LOL

I've run 3 different ones over the years and will stick with bad review of them even if the cam spec page does list slightly different specs...

 

Just to be clear they are the 559 and 560 cam and I don't believe you can get the 560 anymore...
