Need input on the top cam choices for my FXRS

[BadTwin]

The bikes going in for some upgrades and while it's in, i'm considering having a bolt in cam installed. Does anyone have any recommendations on what cam I should get? I'm more concerned with low end power than top end.

On a side note, does anyone have a HyperCharger and are you satisfied with it?
How much of an improvement did you notice?
Thanks all...

Bolt in cam choice for stock compression would be Andrews 26 or SE 203.
Hypercharger gets you no other gain from any other KN or SE filter set up.

Vthunder 3010! There is another person on this evo thread that also likes the 3010. Here is a link that tells you about cams.
http://www.cycle-rama.com/cams.htm Vthunder is a kick A** Choice though in my book as well as another's. IMHO.

The vthunder cams are better than stock but they can't compare to the overall performance of a andrews EV27, a woods W6, woods W6H. I have several customers that have taken out their vthunder cams after riding one of the 3 cams listed above.

I am running a EV27 that replaced a Crane 286.

The difference is amazing. After the change I thought I had a miss only to find out I was hitting the rev limiter.
My old Heritage screams. It ran good before but now comes on much earlier and seems to go on forever or until the limiter takes it out.

It does however depend on the model of bike and what mods have been done along with your riding style.

431-550 Grind - EV27
Timing - 20/36 44/16
Duration - 236 240
Lift - .495 .495

Application: Bolt-in street cam with fast open and close ramps. Similar timing to EV3 but designed to produce a very broad torque band. Pulls 2000 to 6000 rpm. Stock springs

VthunderEVL-3010
.500 .500 3125 .3125 234 234 15/39 39/15
102 102 102 .530" .096" .

Do your own math.


Oh yeah, heard Woods was Way Overated and Overpriced.

I see we have a little attitude. Why don't you explain how you do your math to say the 3010 cam is like a ev 3 and while your at it tell us how you can back your statments about woods cams. I see you have all the numbers out there for us to read now what are we to do with them, please explain what you base your knowledge on?

[baggersport]

I've used bucketloads of ev27's, all with excellent results. Also consider the Andrews easy on the valvetrain.

[FXRocket]

EV 27 is in my FXR. I will never doubt it, all hail the EV-27! Seriously, do it.

I was saying that the ev 27 is, not the 3010. That was your interpretation.

As far as the woods cams are concerned, they cost about twice as much as any other cam out there, and the smallest lift is about a .575, and that is for a sportster. The rest of their cams seem to me to be for people who have had serious head work.

Here are the specs on the Woods 6 Cam. I would think that it would be a good choice for a stage 3, but it is an awful big cam for a stage II, let alone a stage I. Wouldn't you agree?
W6HE EVO
20 / 40
42 / 18
240 240 .
631.631
.196.177

Sorry, if I ruffled your feathers there hdmd88. It was not intentional. JMO.

Now I guess that you could explain to me how Woods and Andrews are better than Vthunder Cams, if you wouldn't mind.

Your putting out numbers of lift, duration, tdc lift, and timing. Where is the overlap numbers that are so important to see how the cam will operate. Look at the timing numbers on your v thunde cams....what do you see different in those cams that you NEVER see on any other grind out there.
Vthunder cams do work better than stock....so do S/E cams, so do Crane cams but none of those would I put in any build I do for a customer. Woods TW6H is only a 240 duration which is a mild duration....but with the lift of .590 it breaths very well which gives me great BMEP. As far as needing head work, spring package slightly larger intake valve, this is true with the tw6h. The EV27 is a bolt in cam that out does the crane, vthunder, and S/E cams in its class. It has a better over lap with less duration than the vthunder so it out pulls the vthunder on top end and also has more torque on bottom end than the vthunder.
Hey put one in your bike and see for your self. Vthunder along with Crane and S/E cams are lazy cams....there is more bang for the buck with Andrews and Woods.
Woods cams are very reasonable priced...the Evo cams are from $195.00 to $250.00 and the Tw Cam cams are around $390.00. Woods also have bolt in cams....not all need head work.
I think the bottom line is you have a vthunder cam and it pulls better than stock so now thats the only cam in the world. You need to open your horizons and give something else a try....I know you will be much more awed.
I do this for a living and what I express here is not my opinoin...it is Dyno Proven.
I'll leave you with the challange again to look at the timing numbers and tell me what you see strange about the complete Vthunder cam line that is non existent in any other grind out there.

Coot,
I have a 1995 FXDWG. Motor has an EV-3 cam, rejetted carb (I don't know the size jets), V&H Propipe, Kuryakyn Hypercharger, and Screamin Eagle Ignition. It runs great IMO and when I roll on the throttle you can sure tell when it hits the right rpm because it takes off like a bullet, relatively speaking for me. I've never ridden a ground-pounder so I don't know what it feels like to unleash 100 hp plus.

Question is...since I ride almost entirely solo is the EV-3 a really good cam for this bike? Also, about how much horsepower would you guess the above set-up is putting out? Whatever it is, it's plenty for me. The engine is otherwise stock besides those items I mentioned.

I bought the bike with the EV-3 already installed. I've read your information in here before and always look forward to reading your statements about engine performance.
Semper Fi,

I get better results out of an EV27 than the EV3, but I would use the 3 before I would use a EV46. As for your hp Id say your in the area of 67 to 72 hp.
Thank you for your kind words Steve.

Doc:

I am another who has also enjoyed your posts and learned from your knowledge.

I've never had my bike on a dyno but have wondered about my approx. HP also.

I'm an old coot like you but I do feel the need for speed every now and then. Gotta love that torque. I don't think you ever outgrow that feeling.

My setup is 90 Heritage evo with SBC formed tool valve job, heads decked for 9.5 compression, No porting. Stock pistons, EV 27 cam, Dyna 2000 ingition, V&H pro pipe with stock baffle.

I have been able to do all my own work so far but I think I would leave the bottom end to an expert when needed.

Bought this bike new in late 1990. Dealer even knocked almost $1000 off the sticker because it was a left over he could not sell. Times sure have changed.

Thanks ya young wipper snapper for the knid words....
To take an educated guess I'd say your around 70 to 75hp. You have the higher compression and that should be good for 2 or 3 more ponies.
So now we know why you can't keep top motor mounts.....your WOT all day long....
