2007 CVO FLHTCUSE2

All runs well tuned. With the swap from SE255 to TW7H we expected a drop in low rpm torque, but expected more above 4000....
Stock heads, stock throttle body, stock headers

Red = Se255 and SuperTrapp Fathshots.
[PE AFR was set too soon and made the afr too rich above 5500. This resulted in the  big drop above 5500, the hp curve would have been a little more horizontal without PE AFR.)
Green = Tw7H and SuperTrapp Fathshots (PE AFR turned off, straight 13.0 afr also above 5500)
Blue =  Tw7H and WB E 2in1 (PE AFR turned off, straight 13.0 afr also above 5500)

The SE255 is very 'exhaust'-friendly. The TW7H likes a good flowing exhaust.

The engine was taken apart for crank and timken.
Is going together with Deweys heads. CR 10:1
We will probably try the TW7H with a 4 degree gear. Just to increase low rpm torque.

OK, I'm convinced. I won't chnge to this cam without doing the headwork and raising the compression. I will ride the bike this year and next with new pipes and a tune. I'll do all the work at once when the warranty is over.


Thanks for your help Dewey!!!!!

Dewey,

This is my friends bike that has the woods 7h cam in it. It was even used as advertisment on the Woods cam site.

Zinister,

1) The sheet is in uncorrected. Check upper right corner. Uncorrected is STD is NO weather and altitude correction.
All other corrections are there to make it easier to compare between different days: SAE, EEC, DIN, ISA, ISO
Comparing between different dyno's will still be different. But above corrections will help also.
In most cases STD will show higher numbers than the other corrections. Corrections of 5% is common.

2) The run starts at 3000 rpm.

3) Compare the rpm points:
3000 =  95 ftlbs
3500 = 114
4000 = 122
4500 = 120
5000 = 114
5500 = 105

4) VH pipes start producing above 3000 rpm.
The pipes we tested have a better low rpm power.

5) Your friends heads have been reworked which should help higher rpm power.
Increasing compression will move the entire curve up.
We tested with stock heads.

6) The stage 1 curve seems to be a bit on the low side. Would be nice to see BOTH in SAE.

Although there are some differences, they are not that far off with our measurement.

I realy like the Wood cams, but on a 110ci the SE255 still seems to be a nice cam.
If we can get the same torque with a later closing cam that would be nice. Therefor we plan to test that TW7H with a 4 degree gear.

I would be very interested in your results!! Please post when you have them completed.


The chart I posted was really to show the compression of the 2 cams on the same dyno. Although I haven't ridden the bike I have been riding with the guy when he's ridden hard, the bike runs very well and pulls away from another buddies Buell pretty easily. The Dyna is was too loud for my taste and he did have some head work done as you say. He doesn't have the high compression pistons but does have roller rockers with the 1.7 ratio instead of stock. Unfortunately he isn't very good at telling me what was done as he lets the dealership tell him what needs to be done and he pays. He's not really into the how and why more the just do it type.

Woods wants his sheets posted on his site in uncorrected. I sent a few and he called me to tell me how he wanted them. Being that my elevation will not show what he wants no reason for me to send him sheets to post on his site. We have done very well with many of his cams.  Not a bash just poiting out a reason for the status of sheets on woods site. This was middle of last year when we spoke on the sheets.

The main thing that has been covered very well is where do you ride the bike. What rpm range are you spending 75+% of your time in. Set the bike up to make the power there. Fun factor will be off the chart. Good luck.

IMHO I think a lot of people forget about that, and just chase the numbers!

[GMR-PERFORMANCE]

Well it is his site so his rules. For anyone that has a dyno above 4000 feet the uncorrected is not going to be a good comparison. Goes back to the same old deal make sure you are looking at sheets that are as close to what you are doing as you can. As well sheets that are recent due to the decline in fuel quality.  What could be done several years ago is not what we are dealing with today.

all stock just thunderheader and se pro tuner, I thank they changed the pro tuner for 2010 and it's a even better unit, I got a se so I would not have to put $6000 in the motor to get good hp and tq.
Thanks Ohio Phil

WOW that is hard to believe. I can't get close to that in mine!

I would be interested to see your bike on a different dyno.  I don't know of a single 110 that has reached those numbers with a pipe and race tuner. 
With an exhaust and race tuner only, expect nothing more than high 80's low 90's hp and 100 +/- 10 TQ. 
Lots of tricks to make a dyno give the numbers a person wants to see.
