I WOULD SAY THE SOUND IS DIFFERENT BOTH SOUND GOOD .I HAVE HAD KERKERS ON LAST 2 BIKES SO GETTING USED TO NEW SOUND IS LIL DIFFERENT.IF LOOKING FOR KERKERS I HAVE A PAIR WITH 4000 MILES ON THEN FOR SALE $250 PLUS SHIPPING.

JDOFLHRIDER - I may be interested. I'll PM you with my email address for pics of the Kerkers.

Thanks

Dyno Dun. Stock FLHTCUSE2, except, RT, AC, Sampson Rolled Slip Ons...

Has anyone had a stock '07 SE dyno tested? The HD literature claims 115 on the torque at 3000 RPM. I'm seeing that folks have added, pipes, filters, tuners, etc. just to get less than 110 ft. lbs. What's the story here?

Where are you referencing, are the referencing Crank or Rear wheel?

Numbers that H-D quotes are always at the crank.

PHAZE · « **Reply #50 on:** December 18, 2006, 04:59:00 PM »

What kind of drives losses would you normally expect from the crank to the rear wheel? Is it greater than 10%?

Found a couple of posts that speak of this...

16G shotgun mufflers for 06 SEVROD

Horsepower and torque

120 HP ?

The above threads were found using "crank hp rear wheel hp" as the search criteria (searching all threads/all posts). There were some others if you wish to use that search criteria.

WELL I'M SORRY THIS HAS SPEED ON IT INSTEAD OF RPM .I WASN'T LOOKING WHEN SERVICE MGR PRINTED IT UP.THIS 07 SEUC HAS D-D FAT CATS(HP BAFFLE),SE AC AND SE PT AND OWNER GRINNING EAR TO EAR LOVE'H HIS BIKE. RUN FILE 1 IS SE AC,RUN FILE 027 IS SE AC ,KERKER SLIP ON'S,AND SE PT RUN FILE 51 IS SE AC,D-D FAT CATS (HP BAFFLE)AND SE PT. RIDES GREAT JDO ONE OF THESE DAYS I'LL LEARN HOW TO MAKE SMALL PIC'S

Just a comment here for those that are interested. I have been poking around on this site for several months looking at what people are doing with engine / exhaust mods and dyno numbers. I see a lot of variations from one bike to the next with similar setups. What I do notice is that there are definitely variations in how each tuner sets up his "correction factor" and "smoothing" (someone else had already broght this up). More so I see some tuners take some liberties with their A/F ratios to a point that I believe is risky, IE A/F ratios at or around stochiometric of 14.7 :1. Sure it bumps the numbers but I don't believe such A/F ratios are a wise idea for WOT on the street, especially once an engine reaches a compression ratio of 9 or 9.5:1. Increased cylinder head temps and potential detonation issues would be my concern. It would also be interesting to see some of these curves with a knock sensor plot and timing curve included (fat chance right?).

What I would be curious to see are various 103 setups dynoed at the same tuner under the same A/F and timing conditions. Does anyone know of such a place or has any of the magazines ever tackled such a task? Unlikely I know but I thought it's worth a try.

Thanks, Bob

Bob,

Maybe a bunch of guys can get together at the dyno truck in Datona or Myrtle...this would be very good to see.

I just put some Zippers stuff in my bike and all I told the dyno guy was make the air/fuel flat @ 12.8 to 13.3. I guess some might like it higher for better gas milage and better numbers...but I dont know the effect on the motor when running the bike at 14.7 for long periods of time? To me the numbers are just a reference to the improvement of the mods. and the flatness of the air fuel curve. I dont care much for my bike has more than your bike numbers game...but I would like my correction numbers and a/f numbers to be the same as well as the same dyno to see what my personal gains are for the mods. I just spent a pretty penny on.

Yes Barry I would agree, it would be nice to compare apples to apples. By the way, I am sure all of the dyno runs are at WOT and gas mileage is typically not an issue here because the economy comes from the part throttle settings. Cars and now the 07 CUSE use O2 sensors to keep the A/F ratio at ~ 14.7:1 (give or take) at part throttle and that's ok because the load on the engine in this range is fairly low. That's how they get the better fuel economy. I don't think many tuners play much with the part throttle stuff. I asked my guy to tweak mine and he has my mileage up to about 40mpg from about 35 on my 06' CUSE.

I have a 2007 black and Orange ultra That I have installed Rienhart true duals air cleaner and a set of Carls Speed shop in Daytona cams. My bike produced 99 hp 113 ft lbs of tk.
Now my bike runs good and runs a lot cooler. I added Amsoil in the motor and regular primary oil and regular Trans fluid and almost all of the noise has went away.

Well just had the bike dyno'd this evening and have to say what a difference in seat of the pants test. Red line is the pcIII 96" w/rineharts download, close but extremly rich at 2000 to 3000 rpm. after tuning I have to say that there is a pretty noticable difference in driveability. Have to say over all I am very pleased so far. And God I love that Rinehart sound!! [smiley=jalapeno.gif] [smiley=orange.gif] [smiley=2vrolijk_20.gif] First time trying attachment. Hope I get it right.
