Dyno results, SE 255 cams vs Wood TW 6-6 cams

Hi all, got the tune done today thanks to Rods Performance in AL again. I'll try to keep this short, this is a 2009 Ultra Classic.

Setup 1. SE 103 flat top pistons, SE 255 cams, mild port/polish & cc'd heads 85.1, stock valves & springs, SEST, stock header, Jackpot slip ons, SE stg 1 air cleaner.
Dyno results were the blue lines 81.44 hp and 97.26 tq

Setup 2. SE 103 flat top pistons, Wood TW 6-6 cams, Wood +4 cam gear, mild port/polish & cc'd heads 85.1, stock valves & springs, SEST, VH power duals header, Monster ovals slip ons, SE stg 1 air cleaner.
Dyno results were the red lines 93.11 hp and 103.76 tq

Gained 11.67 peak hp and 6.5 peak ft lbs tq, but the big difference is the TQ carries out alot farther, at 4500 rpms the Wood setup made 13ft lbs more TQ than the SE 255's, and the Woods made the same TQ at 5000 rpms as the 255's made at 3500.

According to calculations my ccp should be about 199, but I haven't checked it yet.

Not surprised that the woods out performed the 255's but why not post results in corrected numbers for better accuracy, that is what the correction factor is there for, to make comparisons as accurate as possible, from the run conditions it would likely have made little difference but when using the correction factor is as easy as a click of the mouse I see no reason not to use it, either sae or std.

just wondering why they didn't pull the trigger till 3K. Isn't it common to start at 2k. it would be interesting to see that. i'm sure one of the cams hits earlier than the other,as you are just clicking the gears ( very tall )getting er wound up + i just noticed 2 different exhaust. not realy an accurate comparison. just sayin. your sig says 255 v-h 93hp 103 tq, same as the woods 6-6 in set up 2. why are the results and exhaust in set up 1 so different than your sig. seem like the 255 did as good as the 6-6. i'm not sure i understand what you did.

I didn't catch that until I got home and was looking over it. The first time Rod dyno'd my bike it was in STD and showed 1hp and 1.2tq more than this sheet that is uncorrected. I don't know why he used the uncorrected because I saw him click on it in his settings, he may have hit it by mistake when he got ready to print it.

I don't know why Rod starts his pull that late, he did it the same as before.

Bottom line.
Does the bike run better?
Did you feel a big increase in power??
Are you happy ???
If yes is the answer to all of these questions, then a home run has again, been established via Wood cams.

yeah but you also changed your complete pipe system at the same time...so you don't know how much is cam vs pipe.

This is of value to the rider only-to show him his parts have made an improvement over what he had before. Also, if anyone else wants to improve their set up just like this with these exect pipes, and other parts selected are similar; all together; however....

1. Dyno sheet is Uncorrected-(cannot get accurate measurement from 1 set up to another)

2. Pipe changes gives no accurate comparison of cams-what and how much did the pipe play into the improvement? Apples to Oranges-

Sounds like the bike runs alot better though...As parts are changed out and improved, just goes to show what gains there are by modifying a stock set up.

there are actualy 3 setups if you include the one in toddnvals signature with the SE255 cams and the same V-H exhaust as setup #2, wood 6-6 cams with exactly the same results . looks to me like the SE255 & woods 6-6 are not all that different. the 6-6 has longer legs for sure, & the SE255 comes on earlier.but they both build the same power. depends on what kind of riding you do. the stock exhaust with jackpots don't work well . at least with SE255 .

I forgot to change the cams in the signature.

this was your previous sheet in std.
just for comparison FWIW.
For a 500.00 dollar cam swap I would have expected more.....just based on all the hype I hear about them! JMO Sounds like YOU like them and thats all that matters. Enjoy the smile.

I rode the bike some today and here's my thoughts. The 255 cams ran as good, actually felt stronger and quicker up to 3500, than the Wood TW6-6. The Wood cams pull good above 3500 but don't really feel alot stronger than the 255's did, I was expecting a little more since the hp/tq was alot higher with the Wood cams after 4000 rpms. I spent $750 to change to the Wood TW6-6 and +4 gear, EZ install pushrods, gasket, and tune, was it worth it? I have read that the Monster Oval slip ons are very restrictive, and Rod told me that he felt like they were hurting my performance aslo, so I think the big waste of money was buying the exhaust system. I do like the sound of the Wood cams alot better, and I like the looks and sound of the exhaust, so I guess I'm just gonna live with it. I have decided it would be easier and probably cheaper to buy me a play bike and leave my touring bike alone.
