TON of cam threads!

Hey guys new to the forum, just purchased a 13 candy orange rgc...winter cant end soon enough! Im coming from a yamaha raider, which was a great bike, and am thinking ill need a little more power . Been doing a lot of reading and have a few questions.

Keep in mind i will be running a S&S power tune duals with LA choppers slip-ons

1. A lot of guys mention having more torque on a bagger, which i understand, but how much of a difference would a SE 204 differ from a 254e?

2. How is rideability on a motorcycle with a larger cam? is it similar to a car where you experience cam surge at lower rpm? something that would be of concern with those examples or similar? (never had a cam in a vtwin)

3. The guys who go with non SE cams...ever have issue at dealer with warranty? Im aware it voids it but dealer said HD doesnt really check and as long as it was installed by a professional they dont really care.

4. What are the typical dyno numbers you see with a cam only setup?

I appreciate any and all input or comments as long as they are constructive. Been on forums far to long and am used to the "search" comments. I understand how it works but sometimes this is easier than resurrecting a dead thread to ask a simple question.

Also any other cams you may want to recommend would be great!

First, here's a cool toy to compare a large list of cams.
http://www.bigboyzheadporting.com/tccams.htm

#1 204 vs 254e-- The 254e is an emissions legal cam that while adding some, it's in the "barely worth it" category. In the cam comparator listed above. Compare the 204 and 254 and take a look at the overlap number. 3* on the 254 vs 30* of the 204. Overlap is the time the exhaust and intake are open at the same time, the intake opens before the exhaust closes allowing the scavenging effect of the exhaust to help draw the intake charge in. This makes for a much more "efficient" cam and is key to making power.
Also notice the intake close ABDC number, 34 on the 204 vs 43 of the 254, closing the intake earlier allows the 204 can to build more dynamic compresion which builds bottom end torque.

#2 Matched properly to the rest of your combination a cam in the range you're talking about will have no noticeable driveability issues. This is one of the neat things about EFI, the issues with cam events screwing with the fuel delivery go away. In fact, the fuel charge can now be timed with the cam events making things work really nicely.

#3 Mods vs warranty is completely up to the dealer it seems. In most cases if the dealer installs SE parts they are covered by warranty. Discuss it with them to be sure.

#4. I run the SE204 in my 103" '11 RGU, V&H true duals, slip-ons, Ness Big Sucker and Power Vision tuner. The heads have not been off the motor. Never had it on the dyno, but from what I've seen of other's dyno charts it should be in the 105-110ft/lbs area. It runs VERY well, is well mannered and gets good mileage.

I ran an Andrews 37 in my last 2 bikes(95"), ran well, but the 204 makes more power in a more useable range than the 37.

2015 RGU CVO........under continuous change......

Re: TON of cam threads!

If you want the max hp and torque then HD cams are not the way to go.
Currently the top rated bolt in cams in no particular order are, (IMO)
Woods 222
Tman 555 tq
Andrews (damn, i forgot the number)
With a good tune and right exhaust these cams supply hp in th mid to upper 90s and 105+ torque.
I installed the Tman cam over winter.

Welcome to the forum.

As you mentioned about cams voiding your warranty, your exhaust choice can do the same. So its crap shoot to put it plainly

Before choosing a cam and exhaust combination I would ask what is your riding style? Are you wanting good overall power for road trips or high rpm HP for bar hopper??

Cam choices are many, some are a good bolt. Again what is your riding style and what are you wanting overall for power?

If your set on the S&S powertune duals go to Khomewerks.com and buy the same pipe for less. Khromewerks makes the pipe for S&S. I would also suggest to you, to compare the Fullsac & Fuelmoto X pipes as well.

As another option and lowering your expense. Fullsac offers a recore of stock mufflers to give you more performance while retaining the stock muffler cans for the law

Air cleaner choice? There are many

Also your going to need a tuner for the changes your wanting to make. TTS Mastertune, Power Commander to name a few. Personally I would choose the TTS because its widely used and offers the ability to have the tune changed if you decide to do more engine upgrades. Both Fullsac and Fuelmoto offer packages with tuners

I already have the headers and rear section. Im sure i could have found it cheaper but i physically heard the combo and liked it so felt self going with it. The dealer also is throwing in free labor and the SE snorkle (not sure what to call it) style cleaner so i figured why not.

As far as riding style i do mix of both. Since i ride 1up most the time i wasnt really worried about the most torque. In reality i just want it to be as fast as possible one up with just the cam right now.

Not sure what will be used to tune. The tuner im looking to go with has a great reputation around me and uses a flash style program straight from the PC to the ecu so i was planning on going with his recommendation.

As of now im thinking about the woods TW-777, the TMan 555, and the SE 204...pretty much in that order...decisions decisions decisions! Is there much difference between the three?

I can't speak to the differences between the 3, but I am running the t-man 555tq cams and I am very happy. They pull great in the 2500 to 3500 rpm range. I don't need to downshift to pass on the highway anymore. Just roll the throttle and it takes off.

Check this link to a thread I started. My buddy has designed this cam as a bolt in for a stock 103" engine. This cam would give what your asking for. If your interested in his cam, his contact info is at the bottom of this thread >> https://www.roadglide.org/showthread.php?t=29572

John live in Ohio. He's usually available through out the day. Just call his number and if he doesn't answer leave him a message that you are interested in his cams. He will return your call

Edit: I thought his email was posted. Here it is >> [email protected]
