Topic: 95" cam opinions (Read 7138 times)

Puzzled · « **on:** May 08, 2006, 10:01:53 AM »

I know this is a wide open question as opinion plays as much of a part in the decision as do the facts/numbers.

What I have: 95" SERG with the 203's. SE air cleaner, Bassani slip on's, Power commander.

What I have on the shelf: Ported heads, SE roller rockers, SE adjustable push rods, gasket set.

A little history. The ported heads were on my B motor in my softail. With a set of TW60's, a SE Pro Pipe, SE 44 mm CV, SE Intake, and low comp (10:1) cast pistons. The bike made 105 hp and 105 tq. This was not it's best numbers as far as peak, this was the best power curve.

So I know the heads will flow a little bit of air. Now what I'm after is some cam choices. This is more of a highway bike than a around town bike. I can either keep the OEM pistons Harley sent through or replace them with something with a tad bit more compression. The cams can either be standard or geared. I have no preference.

My current setup is netting me 82.8 HP and 94 TQ. Ultimately I'd like to see 1-tens to 1-teens on both HP and TQ.

My wife has an 02 Fatboy, 95 inch, 211 HD cams,SE heads, Dyna ign. module, Mukuni 42 mm carb, roller rockers, adj. pushrods, and V&H Pro-Pipe One. I have to really push my bike to beat her.

Send the heads to someone like Deweys or Big Boys ...you what to end up at 9.6-9.8:1 comp with your flat top pistons and a .030 cometic..1.59 exhaust valve for good port velocity..and a set of 37 g cams. Great bagger build...100\100 witht he torque starting big at 2000 rpm.

As I stated above I have PORTED heads already. No need to send them any where. 100/100 I believe I could achieve with almost any cam bigger than I already have. I'd be gaining 6 in TQ and 18 in HP. It's Ok but not really what I'm after.

The 37's are a good recommendation. They show some nice numbers. I like the HQ0039 also. It's a nice split lift cam.

In a 95 for a touring bike you may also want to look at the Red Shift TC557 or S&S 570. I would go with a gear driven set.

I'll take a look at those two you mentioned. This is a tough decision. [smiley=confused5.gif]Picking cams for my Softail was easy, the biggest I could get to work.

Puzzled · « **Reply #6 on:** May 09, 2006, 07:42:21 AM »

The Red Shift has a nice mild duration at only 242. The S&S offers a split duration of 240/255. The lift on the S&S is on the large side at.570. I know my springs were set up for TW 60's so they would handle the Red Shift's at .557 lift. I'd have to check them to see how much lift they can take. I guess I'll dig out the spring tools some time this week. [smiley=confused5.gif]

DCFIREMANN · « **Reply #7 on:** May 09, 2006, 09:30:36 AM »

Well if you are looking for a high RPM and high HP cam look at the S&S 640. I am running them in my 95 and it runs great.

No I'm not after high RPM. I'd like a real strong mid range cam. 2-5000 rpm. Unfortunately my desired output range will be sacrificed some but I can live with that.

You may want to consider a Woods/Andrews TW400 it runs in the 1teens to low 1-twenties

Yeah .. you got a point about the noise on some Woods cams , although that depends. Some contend that has to do partially with the installation rather than the cams ..

There are some(HD Tech forum ) that have the TW400 and no noise issues.

That doesn't sound much like a Bagger combination. Let me rephrase that, a Touring Bagger combination. That is some nice numbers out of a 95". [smiley=xyxthumbs.gif]

the se-257 will work nice with the combo you have.
is the bike carbed or injected?
what year is the bike?
i thought the heads on a b motor were a little different.

Puzzled · « **Reply #15 on:** May 11, 2006, 05:59:37 PM »

The bike is injected. 2001 with the M&M injection. To my knowledge the heads are (or were) the same on the A & B motors.

Big Time · « **Reply #16 on:** May 12, 2006, 07:29:29 PM »

You're on the right track thinking about the HQ0039s. They open fast and close gently (quietly). They seem to work good at any comp from 9.5 to 10.5. Check out the charts on their site!

Puzzled · « **Reply #17 on:** May 24, 2006, 09:59:49 PM »

I've done tons of reading and comparing and I'm no closer than I was two weeks ago. Where I'm getting hung up is on the power output of these cams. Most of the .510 cams are barely making 100/100. I'd like to think my heads alone would get me close to those numbers with my existing 82 HP./94 TQ. and 203's. Am I wrong? Anything bigger than the .510's and I'm moving the power up the RPM range. I don't necessarily need the power right off of idle but I'd like it fairly close (around 2k). Once the bike is moving how much power do you need to keep it moving? The .570's seem to be very popular but I'm not certain where the power band starts. Gear drive is by far the best way to go but this is not my Hot Rod. I have a 124 in a rigid that runs decent for when I need to get my torque thrills. If that doesn't do it the Busa will cure all my speed needs. So I'm after a nice ridable bagger with a little extra power. Chain drive cams and a set of replacement shoes will do what I need.

When you first suggested these I thought they would be to big. Now I'm having second thoughts. My TW60's were more of a top end cam but they made the power low also. They made 90 TQ @ 2000 RPM with a peak of 105.8 @ 4250 and peak HP of 104.8 at 5750 RPM. The peak HP with TW60's is too high for this application but I wonder where the 55's work?

HDMonsterTorque · « **Reply #19 on:** May 25, 2006, 04:56:58 AM »

Maximum lift doesn't effect the rpm range (or very little).
Look at the Wood TW6 and TW6H, both have the same rpm range. But the H has high lift.

BTW, the M&M injection will probably keep te numbers low.
Do you want the keep the injection? If not, switching to carb on a M&M bike is quite easy.

TQ MONSTER I would have to agree with you. I would also look at the S&S 585 cams or even the 625 cams for a 95. Hook it up with a good set of heads 10.5 to 1 compression and either a CV44 or a S&S "G" with a Thunder Jet. Then you have a menu for some H/P.

My 95 spun the rear wheel at 110 and it was wet sumping at the time. With the problem corrected I can feel it has a bunch more power now. I just need to get it on the tread mill again.

I will be keeping the injection. Again this is not my Hot Rod bike. I'm after a set of cams to compliment my heads with a relatively early entry to the power curve. (I think) What determines where the power curve works?

PUZZLED there are a few things you need to look at. It all has to with valve timing. Valve opening and closing, overlap, and duration. The first thing to look at is your duration. The higher the duration the higher the rpm curve (as far as power) and the more compression you MUST have. Unless you have a turbo or supercharger. These 2 items you will run lower compression and set the boost on the device which will determine you your final compression. If you want a lower power curve look for early valve opening and closings and a lower duration. If you add lift you will increase your power but not your power curve.
