S&S 144 engine Specs

[No Cents]

"A"...I don't think this was designed as a touring motor intended for long term use.
I was shocked it comes with a 6 month warranty to tell you the truth.
This engine isn't going to be for the faint of heart!
I think if it's well maintained it will last a long time...but if your ripping on it...something will be breaking. More than likely the weaker links on the bike initially. Once all that has been worked out...Lord knows what's going to happen.

Ray, you may be in that same situation soon too.  Don't know if that is a good thing or a bad thing though.

 I'm there already Rob.
I've had clutch and comp issues and I've seen evidence of tranny trap door flex. All this kind of stuff will have to be addressed with an engine like this one.
A 144"er will show stuff like what I've seen...even faster I would think.
But man...just think of all that power they will make.

Even if I could afford the engine I couldn't afford to feed it tires.

It would be a smart move to own stock in your favorite rear tire manufacturer.

I don't think engine size has much to do with engine longevity.  How it is built and what is being done to it is more important.  If the correct upgrades are made to the rest of the bike.  I own a 454 in a motorhome.  This isn't the same 454 in my buddy's drag boat.

it has the 635 ho cam in it ?

Or not 100% sure its the same one ?

[2006FXDCI]

I was told it was the 635HO cam by S&S today and was given a part # for that cam for the S&S oil pump gear drive cam . Part #330-0369

[TorQuePimp]

in that case the advertised numbers are pretty much meaningless

I would be interested in seeing a set of B-3 heads tho

[CowboyTutt]

Torque, why so?  I honestly don't understand.  Are the tolerances so bad that the cam specs vary a lot? -Tutt

[TorQuePimp]

  Not cam specs....advertised horsepower numbers

  Big engine with huge ports,really big bore and they stick a little puppy cam and less than 10.5-1 compression and it has only been tested with one pipe.

  A little more squeeze and a different cam and exhaust.....things could get interesting.

[JohnCA58]

    would like to expect 1.25 hp per cubic inch. with more c.r. and cam

Probably easier to offer a warranty on what would basically be considered a de-tuned race motor. I'm betting they know many won't leave well enough alone - but once the fun starts, the warranty is out the window. Might have been planned that way... 
Bet it runs pretty damn good even at 10.5:1 

[76shuvlinoff]

I would imagine S&S has a recipe and package for more spank, costs a bit more, likely voids the warranty.

You know, like H-D does...

Watch for the Star Racing versions that will no doubt surface...

Ding Ding Ding we have a winner.

[Templer]

Look at the rocker ratio used with those .635  IT MADE 130 HP/120 tork  with a 106/635HO CNC package so This should be fun. There is MORE left on the table. WARRANTY!!!!!!  Bets on -2 cams have been taken.
Pony with BIG heart!!!!

Who gets the honor of tuning the first HTT 144 ?

[No Cents]

 Paradise Performance...would be a safe bet

S&S oil pump set up no cams for it other than what S&S has to offer. You could remove all of it and buy new pump plate cam cover etc.. More power for what. You got guys out there that cannot figure out how to make 140 hp work with out burning out the clutch, tearing up drive train parts..

Then let the dyno games start  as not like it's a mystery some drums are reading higher than others,....or maybe race track results, who knows ,

But if I can pull a 7.30 in the 1/8 on a  bagger with a basic out the box S&S engine with approx  20 less hp and almost the reduction on tq .. I am betting that bike with a rider that can figure out you dont need max rpm to launch and not burn down parts will be a 10 second member or high 6 if its the 1/8 mile crowd.. 

[No Cents]

 Steve...Randy's bike will probably never see the drag strip as being a competitor...spectator...yes.
It will however be one badass bar hopper bagger.
