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.

Scott,

What's your opinion comparing the Wood 555 and the TR 555? 

                 Intake   Exhaust   Int/Exh Lift   Int/Exh Duration   Int/Exh TDC   Overlap

Wood 555    21/41    43/19        555/555          242/242          .189/.178        40

TR 555        23/41    45/21        555/555          244/246          .212/.196        44

What is not shown is seat to seat duration. That would tell a little more.
The TMan cam offers the potential for a very little more and less than the Wood cam all at the same time depending on the tune, and pipe mainly plus more dependant on the ports. Overlap is more, the main factor that differentiates them.
If I was using a Tman grind I would bypass their 555, port the heads and raise the compression and go for their 625, same timing but now you can get the benefits of the added breathing more compression and the overlap. Better balanced combination.
Once again with OEM bathtub heads (not CVO) this analogy would be a little different.

Alright here is a new one for you.. The dealership called me to let me know what was wrong with my bike today.. They found my cigarette lighter in my inner primary.. Yep thats right my cigarette lighter. I lost it a couple of months ago.  Evidently when it fell out and hit the ground it bounced back up into my drive belt and found its way to the inner primary.  They took pitcures so hopefully I will get the pitcures and post them later. All is well and I should have the dyno results in a couple of day.

Dyno Run Complete.

Blue line Stock SE 255 Cam: 91 HP 111 TQ
Red line TW-555 Cam: 98 HP 111 TQ

I am going to work with the T-max support to see if we can improve timing and get a little more out of the cam.  The next step will be for me to get some head work done like many of you have suggested

Main thing it needs is a half point more compression and the squish fixed. That comes with head mill and a thinner head gasket.

Since my last post I've been working with T-Max to get the timing correct to get the most out of this cam.  The seat test tells me they've got it right now   :orange:  :huepfenjump3:. I will be putting on the dyno later this week to see if we really have made any difference.  I will post the results once I have them.

We have a client in now from Conn., that we have completed our Stage II CVO cylinder head mods, with compression set, using a Wood 555, 58mm S/E FBW t/body, and mufflers he provided.
Will begin the assembly process in a day our so, and then to the tuner.
Guarantee it'll be a real good runner. I'll keep everyone posted. :)

We brought the engine to temp, and did a couple pulls(absolutely, totally untuned)here on our Dynojet 150.
Running VERY rich, it showed 113/114, semi-consistantly.
Pulling at 6000, like it is at 3000, and the torque litterally flatlines.
Now it will go to www.joescyclerepair.com.

Birdman, FWIW, either change that Transmission Pulley nut or lube
it up and dry it good real good.  I just spend some good time getting mine
off the Street Bob and between all the LOCTITE(I think a whole bottle) and
the rust it was a mutha and took a 3/4 in IR Impact to bust it free.

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.


There is NO SUBSTITUTE for a good professional tune...
