I have a stock 88" and considering changing the cam. I am not little guy at 260. My local wrench is recommending the 211 cam. Can anyone give me the pros and cons of this cam. I will probably end up adding the 96" sometime in the future but for now may just change cams. Anyone have any experiene with this cam 88" or 96"?

 

A 211 is not a great choice for an 88", much better suited to a big bore. If you are gonna switch, gear drive is the ONLY way to go!

 

Yep he told me that it woud do OK stock but would be a good fit when I upgraded to the big bore. I was wondering what the characteristics of the cam are? Would it be a bad fit in a stock motor and how so?

 

I don't understand why they recommend 211's for big heavy bikes. The 211's are a mid to upper cam. Big heavy bikes could really use more in the low to mid range. The 211's also prefer a bump in compression. A stock 88 with stock heads has about as low of compression as you can go. The 211's are a good fit with HC cast pistons, 95" and a lighter bike like a Dyna, IMO.

In a Big heavy bike like a touring model, road king, etc, AND staying 88" the 203's or 204's would be a better choice, IMO. Both those cams can shine with a little additional work (porting) as well aas the 211's.

Here is a Dyno from a 88" with 204 cams.

 

Thats the kind of info that I am looking for Springer. Thanks. When talking about cams everyone just says "I like this one" or " I like that one".
I want to know what people have and specifically why they like it. Its not a cheap job if you include the big bore and I dont want to have to do it twice. I want something that wil give me a big boost in a stock 88" engine and will even get better with the 96"
Thanks again Springer,,, good stuff.

 

Go with the Andrews 26G cam, it will work well for a heavy bike now and with 95 kit later. It also uses gear drive which none of the S.E. cams use. Before you do any upgrades to the motor decide on what your final goal is so that you don't end up buying non-compattable parts and having to do aka BUY everything twice [* like me [8D]].

 

This is exactly the route I'm taking. I had been given a recommendation of a 37g as well. I am only doing the cams this winter and will do the 95" sometime in the following year. The 26g states it is for 2-up touring which is what I do most.

 

Just FYI for you guys looking to install the TW26 andrews cam.....I rode a bike with those in a stock ( stage 1 ) and it is fairly strong from idle up to 3500 rpms, but is FLAT at anything over that. I felt like I was killing the bike to turn it over 4,000. To me, it would not be enjoyable to ride. I like the TW6 Woods cam, because under most riding conditions, it pulls hard. It really comes on strong at 2500 rpm's and will pull to 8500 ( of course the stock rev limiter will not allow that ). What occurred to me is what rpm are you at, when you are going 60 in high gear? 2500-2800. If you need to pass.....this cam hits hard, just roll it on.

I hope this helps , everyone one has thier own favorites, all the ones below are well liked , each has thier merits.

here is a comparison of popular cams at .510 lift or less , these are good for mild builds.

The TW37 is good up to 9.8:1 compression , past that the TW31 is better , same lift different timing.
The Woods TW6 is similar, there is also an TW6HG that is WAY different , and is a Monster cam.


As a general rule, cams with 220-235 degrees of duration tend to produce good low end torque. Cams with 235-250 degrees of duration tend to work best in the mid-ranges and cams over 260 degrees work best for top end power. Camshaft overlap duration less than 30 degrees tends to produce good low end power. Lobe Separation Angles (LSA) of 100-103 degrees tend to produce power at the low end.

Cams with valve lifts .500 inches and under, with a duration under 250 degrees are generally considered bolt-in. Cams over .500 inches lift and 250 degrees duration require increased compression and head work to work best.

Great info Nidan. After studying over all of those figures, it sort of looks like the 204s may be the way for me to go. Looks like they should do a good job and when I get the big bore later it should work nicely together.
