Still no welded crank?

Ever see an S&S crank slip?

yes

But enough stress against a welded crank, and it may twist as well. 

Im intrested. Wonder what the otd price would be? Probly need tb,pipes,clutch,labor,tune

$4,000 would be a low quote over the cost of the crate engine.  That's primary, labor, transmission, tuner, tune....out the door.

Does the 70mm tb come with the price?  The VFI would be something I would consider.  Especially since only one pipe is offered.  IME exhaust has more influence on air flow over timing.  To a point.

S&S has a video on cranks they are snapping to prove a point.  I could post up a picture of a REV perf crank we have with aluminum crank plug  Lets face it guys if you distort the plug as you press it in what good is it going to be??

I got a look at the S&S dyno sheet on this motor today and the BVHOB 127ci beats it on HP/TQ from idle to 5250 rpm. Way to go Razorback Performance
S&S 

The 144 is a crate engine, the first one has not even fired up,...and  already being stated to produce numbers,....  or better a guess as to it will make.. It may on a hot dyno and that will only lead to the next thing and that is that I must have a bad 144 as so and so got this on his dyno..    Or that the tuner is the best ..    as he was able to get this from that.. Who ever does it not pointing fingers, so lets not go down that road.

Out the box engine with the right parts off the check list that will produce 155+ is not a bad running engine. Look at he amount of 150 + HP bikes out there.. its not common. Most had way more than bolt a engine into the frame and tune it , to get to the 150+ mark. 

I'd like to see what this does in the hands of a good builder, probably 180-200hp, but we already have a 145" that's been around for ages, no one really runs them?

It's already done 1.18 and 1.21 hp per ci as a crate .
Of course it didn't have a fatcat or dresser duals on it either .
That's not asking a lot out of a low compression B headed motor .

I have seen 165 and 162 hp posted.  That's 1.145 and 1.125 per cubic inch and 1.048 for torque.  174 hp would be great if it was 1.2.  Depending on the dyno used.  It might show 1.3.

Chris Rivas posted on Facebook his S&S 144 crate engine made 170 hp right out of the box...before adding a charger to it.

No guess here, I was shown the dyno sheet supplied to the dealer by S&S. It was a Dyno-jet dyno run SAE correction of 1.01, smoothing on 5. The run started at 2100rpm, made 100tq at 2500, peak tq of 151 at 4000rpm, about 142/142 at 5250, peak hp of 162 at 6125rpm and about 160hp at 6450rpm when the run ended.
Bike was a 09FLHT according to the sheet and included all the extras recommended by S&S.
It was made clear that this is a race motor, and that like any race motor there will be vibration and mechanical noise (specified valve train and piston). Fuel mileage was quoted as 30-34mpg.
With the intake and exhaust packages from S&S the MSRP was north of $11,500 doing the math in my head.
Just as I said with the 120R this T144 motor if run as delivered will have a race motor personality yet make street hp.

The real difference here is I am a buyer and you are a seller.

I am not saying it will not make more power . Here is the test run that I think you where talking about ?? I agree very nice but its not north of 170 yet. Pipe and tune..  Ok so an 09 has the wider rear tire with more mass, so a 08 with a lighter rear tire may make more. But as we all know the transmissions in these bikes have been an issue when it comes to making power. So a trans with a billet door or even better a stronger trans all together may show some better numbers.  That is more so my point.

I saw that one too . Ran out of injector .

I can tell you for a fact that it did not run out of injector.That run was made with a 12.15 GPS inj by racetronixs .

It is not running a monster cam. Not like its going to pull in the 6500+ range with the 635 cam and 10.47.1 comp ratio.

Sorry I wasn't talking to you .

 regardless of who you where "talking " to the information you posted  is incorrect .

What information ?
The 170 and the 175 hp runs were with a undersized  Injector .
as I understand it,That was corrected before the 250 hp run

All the speculation and na say will be cleared up for me in a few weeks .
12.2 injector is way to big for this motor N/A    were they thinking

Huh, 96 lb./hr. injectors... Were/are they planning on some boost!?

Jim,

I think everyone is anxious to see what this beast does on your dyno. I think you are correct about the injector. Will add, that I think it is very interesting (and telling) where these three motors were offered and wound up at. I am not surprised that one of the first units for sale was offered to Ray. Not trying to start a Steve Cole gang war, but what software do you plan to tune this with?

 Randy has one of those new Power Visions to use as his tuner.
S&S sent him a base map to load into it for initial heat cycles.

Weird how people can't figure that any engine someone produces can't be made to have more power. A factory offering is most times not a track offering. It may get a race label but if it was offered with 240 hp would you really think about putting it in your street bike. My friend James just finished up a 165mph quarter with the EVO style 140 and yet rode the bike in the Black Hills this fall. I'm sure his engine isn't in the same tune 140's or 145 were originally sold in. Once these are out let the fun begin. 

Conservative marketing by the producer. What you want to do to it above and beyond is the option of the consumer. That engine will spank with more $ and effort for sure.
