Kryteon wants to know Dino or Syn?
Kuryakyn Cams

Has anybody here tried the Kuryakyn Wild Thing (Mike Roland) cams? I'm debating between the TC-2G and the Andrews 37g. The Wild Things are reported to be a lot quieter, but I'm concerned about losing low end torque. I know JMORTON switched from Woods 5g (I think) to the Kuryakyn TC-4g, and seems to like them, but I'm wondering what others think too?

Thanks,

Kryteon

Give me the cam numbers...intake open, intake close....exhaust open, exhaust close. With that info I can tell you or give you a comparison to the two cams your looking at.

Head on over to the Harley Tech Talk forum. Mike Roland, the cam designer for the Kuryakyn's, is on that board answering questions about the cams.

Thanks AZTriker.....you allready did this one didn't you....I bet you got a grin from ear to ear, lol
Well lets give this man the news hes waiting for.
The TC2-G cam will turn on at 3140 rpm, with the late closing intake you better get some head work done and some extra compression in the combustion chamber. That cam will pull hard up to 5200 rpm but your stock heads only breath to 4500 rpms ...thats why with this cam you need head work, plus I'd go one step futher and gear my bike to a final drive of 3.37:1. If this is your choice get some one a Deweys to set you up with the head work and the correct compression you need.
Now the 37G... this cam has a early closing intake valve which will give you more cylinder pressure on the lower rpm band...it will turn on at 2540 rpm and pull hard to 4600 rpms. No head work is required here but I would freshen up my valves to be sure I am sealing the combustion chamber. Stock gearing of 3.15:1 will be good enough because you have more torque on the bottom end with this cam.
Well, there you go now you know where the cams perform at now its up to you to select the one that fits your riding style.(The Numbers don't lie) Oh by the way I don't see the TC2-G cam being any quieter than the 37G. "Quiet cams" isn't a good selling point to me.
Good Luck

They both have 32 degrees of overlap but thats where the similarity ends. You heard they are quieter from someone that had just switched from a Woods ! From looking at the #s I would say that the andrews 37 will still have better TQ. What say you HD Doc ? I would say that its holding the intake open to long for it to build good TQ.

hdmd88,

Yea I was grinning. But I appreciated the detail you went into. So much so that I would like your opinion of the Head-Quarters 0034G compared to the 37G. Here are the numbers on the HQ's.

Intake .500? 236 20/36
Exhaust .500? 250 51/19

My brother is ordering the HD's.

Thanks much....

Your right again Bullet...the 37G will be stronger on the bottom, but with the compression and head work the other cam will walk away from the 37G. Personally the 37G would be more fun or better stated more bang for the buck. I never ran a 37G but like I said numbers don't lie.
Will the real Silver Bullet please stand up, :p :p :p You are the man!!!!

Mr Trike,
The H-Q cam will have a little more pull on top end due to the larger overlap but the lift is larger on the 37G if I'm not mistaken, and I like the bigger lift. All I see here is a narrow Lobe Seperation Angle with a small lift which gives that overlap number. Stock Gearing would work, no head work needed, power band from 2680 rpm to 4800 rpm with a flat torque line. The intake duration is the same but the int. valve opens earlier and closes earlier....If you advanced the 37G timing 2 degrees it would be a better cam than the H-Q.
Its late and time for bed....Jmorton I will be back with you tomorrow.
Good Night

My friend has the same build that I do on his FLHTC: larger bore and ported heads. I've ridden his bike with the Andrews 37G, and if I had it to do over (and I might), I'd go with that cam in a heartbeat. Super torque and power where you want it. The Kury's may be great, but I'd wait for a product to get a track record before I'd buy it.

I have said it before and will say it again. The Andrews 37G may not always be the right cam,BUT it is NEVER the wrong cam ! I use LOTS of them with 9.8 - 1 comp with 95 inch and have never had a customer that wasn't COMPLETELY HAPPY. Deweys Heads,37G cam, good exhaust {there are many} carb or F.I. runs like stock-pulls like a tractor ! Forget about downshifting. 100+ lbs.tq every time. Wonder how the rock is doing with his new bus? WILD WEED WHACKERS. Bet he is busy.

GRock wants to know Dino or Syn?
Sorry guys, no time to talk. Surrounded by this plastic string thing stuff. Keeps gettin' bigger. Ummm..... help?

WILD WEED WHACKERS You kill me!

Bullet, if I use that name do you want royalties?? Also, do you know if this string stuff gets wound in a clockwise or counter clockwise direction?
(Damn, didn't think I would have this much trouble starting up new venture).

Kryteon wants to know Dino or Syn?
Thanks to all for their response. I've been following the threads on these cams over at the HTT site, but to date only one person has actually installed them. I'm planning on doing a 95", with SBC Scottsman heads, this winter and was debating between the 37g and the TC-2g. I think you all have pretty much convinced me to stick with the 37g, unless between now and then, someone can come up with a real world dyno comparison that shows the Kuryakyn cams to be better.

Thanks again,

Kryteon
