Well.. to me.. that first pic, the adjuster looks WAY more even than the 2nd. one. that 2nd one the adjuster is on the tip...

Well fellas, I reset my degree wheel to double check my work...... because unlike Krandall, I actually am stupid..... Turns out this cam came up at 270° (4° bigger than the web 4) but the lift was correct.

So off it goes to test pilot Troy who is evidently fearless :nod:

Oh it does! This is a kamikaze run with the adjuster nuts installed from the bottom! We are finding some preliminary numbers and then we are gonna yank that dude out to get into production. But no, Troys bike can no way run this cam long term without some pretty rowdy changes

Looks like cool stuff,

what type of piston to valve tolerences are you going to be running or what do you feel is safe for a 9000 rpm engine?

there is defiently a lot more room for power in different cams especially when you factor in the long rod builds thats something i was planning on trying to master through the winter. Ive been using the web 4 all season but have some ideas for hopefully good results, I will definetly be curious to see what you come up with

barker heads run a shorter valve also works well

VelociRaptor

Getting the spring setup really isnt hard to do, hard part is figuring out the right valve tip height to get the geometry in line were it needs to be on the rocker. The right valve length and spring pocket depth will get it, Kenny just spent the time to figure it out.

phucker

i am definately interested to see what this does. buti think it might be a little to big for me lol. im only running a little 804

Troy

Don't be scared Phucker, I'm only running a very little 770, it's just a widdle guy  :thumbs:

Right now I have .080" on the exhaust with one of the new CP pistons. We DEFINITELY don't use a shorter valve, especially with the Web 4.... Remind me to tell you why sometime. I won't go into it on here

That was a big part of it. The nose velocity and closing ramp were probably the hardest part to figure out. This is an offset lobe that is pretty crazy. I think that is gonna be the whole trick.

We are gonna be building taller cams with less duration to keep the power huge and the RPM reasonable  :thumbs:

LOL Coop, you'll find with me I can keep a hell of a secret until the phone rings, then I sing like a canary  :lol:  No secrets here, just trying to get some cams to play with and see where they stack up.  I have the RHC 14 and a Web 4, hoping to get an RE cam and a Daniel (new custom) cam, and anything else that is supposed to be cool on my hands to see what the baddest one out there is.
