I just installed Bobby Wood's new TW-555 cams with his directional roller lifters. It feels like I have more torque and power especially at the high end.  I am not sure what numbers they are making yet.  I had 111 TQ and 91 HP a week prior to installing the cams and lifters.  I went back to shop that did my baseline run to see what the new TQ and HP numbers are but he wasn't able to run it.  He said it sounds like the transmission pulley bearing is bad and suggested I take it to the local HD shop and have it looked at and fixed under warranty.  Once I get it back and have the results from the dyno run I will post the graph and numbers.

Has anyone else installed the TW-555 cams, if so, how do you like them?

Fuel Moto is using this cam in a 107 package they offer. Seems to work very well in that combo. Did you do any head work / head gasket change?

I'll be watching for your dyno post.

You may be one of the first for a 110"

I didn't do any head work. The other mods I've done are Thunder max ECM, V&H power duals, Fullsac 2.25  muffler cores.

Thanks Bman

I'm looking at the Wood 555, T-Man 555 or Cyclerama 575. However, everytime I ride her as is, I'm not sure why I want to change anything. It's a sickness.

Just what my Little Pea Brain was thinking!


I have been looking at this cam also??

I'll have to agree with it being a sickness  There really was no reason for me to make the change other then I just feel the need for speed.

I notice the stock SE 255 cams have the same lift .555 however, the duration of the lift is different. 

[timtoolman]

there is more difference than that, the cams dont even compare   just in lift only

[Birdman]

Thats good to know..   Once I knew they had the same lift I wasn't sure I was going to be happy with them.. Now that I have some miles on them and the Tmax turner is making the necessary adjustment I have noticed a difference   :orange:ce.

Well I mean if I was going to ... never mind!

The T-Max doesn't change that much on its own for you though.  A little fuel.  But that's it.  To really take advantage of differences in cams one would think real effect would come from changes in timing rather than just compensating fuel to keep the AFR where it was to begin with.  And the T-Max doesn't touch timing on its own.

Well I mean if I was going to when I do ... never mind!

I fixed your post for you.

You need to re-surface the heads in order to expose the worth of that cam.(and perhaps some head work)
10.4-5 would be the target area.
Wood 555/Our Stage III Heads/107"/OE t/body, and bagger duals..........110.2 hp/120.3 ft/lbs.
Carrys 100 ft/lbs from 2500-5700, and peaks at 3400.
Only 12 pulls(?) on the dyno it was tuned on.

Your correct about the fuel adjustment.  It will make changes in to the base map up to 10% while you are riding, anything after 10% is written to the module and you can chose to apply the corrections once you connect to the software and apply auto correction to the learned fuel offset. 

While I am on the Dyno I will be adjusting the timing to make sure it is running at peak performance.
