Great work Daren, like the look of the RS468 in tests so far.
re- Joes 475 do you think the billet cat 2-1 would bring the left side up & hold on ?
The Billet Cat could very well do just that, it has improved the left side of the graph on every other cam I have tried it on.

Only one way to find out. :teeth:

Very nice Daren.  Just shows the great results that can be had when you spend the time to tune it and use a quality pipe.  :up:

Thanks Eric. I agree on the cam development as well, the S&S 475 is a good example of what you said, it gives on the left but makes gains on the right as shown in Joe's latest dyno graph.

Some added compression and head work would really make that cam shine IMO.

Wes is going to do a set of heads for me when he gets caught up, and I may try them on the 107 with a new Cycle-Rama cam that will be available soon, before going bigger on the cubes.

R&D is fun, but sure does lighten the wallet..Lol.

This has long been the big question in the testing world because trying different cams back to back in an engine in totally stock form as you have shown will give you the best stage two bolt-in setup. It does not show what each cam is capable of doing with a particular head/port configuration on a given engine displacement when the compression is optimized.  I have talked with Vic about this before and the best scenario IMHO is if the cam install is intended as a stepping stone to a later build then bolt it in and tune it.  I ride with many people that have had more than one bike and have never gone beyond stage two so for them I say skip the heavier adjustable pushrods, and pull the heads to optimize the compression for that bolt in cam to get the most bang out of the total package. As explained in their video Zippers did a great job of studying the stock engine configuration and designing the cam to work with it's strong points and short comings.

Re: Milwaukee Eight testing.

Stopped by Sheffer Performance today and got an invitation to test ride the latest creative combo Daren has assembled on his M8.

Combination included the following:
Red shift 468 cam
D&D's Billet cat header
Rush wrath exhaust pipe 2.5" baffle
Heavy breather
Barnett Clutch springs
Stock heads
Full tank of gas - ha ha

Awesome combo in short form.  The exhaust signature and cam lope was in my ears very similar to the SE 204 - a favorite of mine.  Distinctive and strong. 

To help move the exhaust front to back the  D&D Billet cat craftily fitted with a Wrath exhaust pipe which was -not - obnoxious or over bearing when rolling through the Rpm's.

Throttle  response was crisp and snappy - very responsive with excellent  low speed manners. This combination pulls like a while not killing your ears.

With the Rush Wrath exhaust pipe one would be able to choose the baffle they would like - Daren had a 2.5" diameter installed and there  may be plans for a 2.25" baffle.  I would like to try the 2.25" baffle.

Bottom line - this combination is impressive.  I have no idea what the dyno numbers are and frankly don't care to know. Damn thing is seriously impressive.

Final thoughts are: awesome through the gears, great manners in slow speed maneuvers, excellent exhaust note and most of all - sounds like a Harley.

For the record- I stopped by to talk about my 13 Road Glide Ultra tuning issue and a future project of installing a 114 or 117 in my M8. For me - I can confidently say the above combination would and will satisfy my touring bike requirements.

Did I just read that Darren has a Heavy breather, any testing with it yet?

Just saw the 468 dyno on page 10.
Very impressive curve however you can't ride paper.
Having rode the bike and then see the dyno sheet- I agree with what wrote.
It pulls like a ... Fright train and sounds awesome.

Note:
the dyno sheet identifies the breather as a Stealth AC with large element.
I have no idea who makes it.
My mistake - if it's not round it's just an ugly sucker in my book.

Thanks for your appraisal, good to hear how it performs on the road as well ,great work Daren
