Wood TW6-6 TW-555 Cam Dyno Test by Fuel Moto

Couldn't agree more boogaloo. Ramp angles, transition points, relative timings, etc. etc. etc. all influenced by stuff like CR, piston top shape, intake and exhaust port size, runner lengths/diameters, etc. etc. etc. I guess that's why guys like Bobby Wood and Jamie do the stuff they do for us.
 
Is it just me or are these Woods cams out performing the 255's at their own game?

Nearly every dyno sheet I've seen has the TW6-6 (and now the 555) beating the 255's in the same RPM range.
I haven't located any 255 dyno sheets on near stock bikes that have curves or numbers better than these woods cams. Somebody got one?

It seems the only advantage the 255s have now is that they are cheap.

I might have two 255s sets for sale... cause if I'm going through the trouble of opening the cam chest to install cams I'm going to go ahead and put in the best performing cam...

Awesome thread! Makes me want to change my stock headers out for a Jackpot system. Seems I am giving up more HP's, tq than I thought running the set up I have.

Scott at Hillside listed two main reasons; bring the tq curve even further left, and raise the compression with an earlier intake close. They have not done any builds (to my knowledge, Scott chime in) but their simulations say and Bob Woods would say that these cams really want 10.4-10.5 compression. So, until I go to bigger bore and headwork, I'm OK spending a little extra money ($50 for crank sprocket 4* advance from Andrews).

Also, an earlier poster asked about the 107 "package". Actually, Hillside bores out the stock jugs to 107, and fits them with their proprietary Wiseco pistons. As a reminder, I don't ride a bagger, I have a XBNZ, and don't ride 2-up or as heavy as most on this forum, so my style and goals are different.

As our 96" Wood Knight Prowler cam testing comes to a close on our 2010 bike we do have another combination to test. We are currently tearing the bike down and installing what we will call the Fuel Moto Stage II 107" kit. This combination will include the Wood TW-555 cams, Revolution 107" pistons/cylinders, and CNC ported heads to our specs. We should have it finished up over the weekend and will post technical information and dyno results as we progress. We are expecting some pretty awesome #s from this combination.
 
NOW it's gonna get interesting!!

BTW, I'm not buying that Checkmate boat, and with my buddy (John F...did he stop buy you yesterday Jamie?) buying a new 110" CVO.......I may be 1st in line to do your 107 kit!!!!
 
Damnit Jamie, I'm still saving up for the exhaust, then y'all come up with this cam stuff, and next you're dangling more cookies out there. Sure sounds like most of us are going to have some fun with this stuff though.

Thanks,
