Here are some results from a cam swap we did yesterday. This bike is a 2009 CVO 110" Road Glide. For exhaust it has a non catalyst head pipe and Klock Werks mufflers, it was also equipped with a Dynojet PC-V since last year. This bike belongs to a long time Fuel Moto customer from the other side of the state that has brought us several of his bikes over the years for dyno tuning and services. He was looking for better performance, better response, as well as cooler running. While the stock SE255 cams are very good for very low end performance we were looking for improvements thru out the entire RPM range. We chose the Wood TW-7H which has a the same open/closing specs and duration as the popular TW6-6, however the TW-7H has .575 lift versus the .510 lift of the TW6-6 which will work especially well on the 110" motor, there is also a big difference in dynamic compression compared to the stock SE255 cams. The timing of the TW-7H will allow the motor to rev more freely and be less prone to detonation. We started with a full dyno evaluation just as the bike came in which was 90Hp/108Tq. Conditions were poor as we had 90+ degrees and over 40% humidity. We did the cam swap, gave it a full dyno tune and the final numbers we 110Hp/118Tq, when we finished the tune it was over 100 degrees and very humid however the results are very impressive with nealy +20Hp/10Tq gain from a cam swap. The before and after results are shown below. The improvement is excellent, with immediate response and the idle is awesome. I will try to get some video before the bike is picked up. More to come.......

 

Very nice!!

 

That's impressive.

 

Nearly +20Hp and 10Tq gain....wow , I got +12hp/12Tq on my 96" motor with the TW6-6 cams and i am really happy with them.

This confirm that Woods cams rocks

 

Like to see the same cam in a 96 stage one and see what she will do!

 

Anybodys opinion on this that knows what he's talking about would be great ! Can or should this cam be used in a stock 2010 96inch motor ? I have a SE heavy, breather pc-v, 4" rineharts , I was wondering on the lift . Is it to much for my stock springs , or will my stock springs be ok with this cam ( tw-7h ) ? I know the SE255 are great also , just wondering if this cam will work . Again completly stock no head work , just a cam change ! Jamie you can chim in here if you will ! Thanks . . . . .

 

I have the same cam in my 103" bb with no headwork - they were recommended to me by Bob Woods. I was also told the stock beehives were fine. I haven't had mine on dyno for numbers but it pulls great and I'm happy.

 

Yes you can use the TW-7H with stock valve springs on a 96" motor, however if you have stock compression and cylinder heads you would be better suited to use the TW6-6 which works excellent in the stock 96" motors.

 

TW6-6 which works excellent in the stock 96" motors

We'll see Friday!

Hi Chris, Keith was working on your bike this morning and already has the cams installed and motor back together on your Ultra. We will be finishing up everything today but I am going to wait until tomorrow to tune it when we have better conditions, we are currently under Tornado warnings with very bad humidity. I will let you know Friday A.M how it turns out and with your approval can post up the results as well.
