OK ED,

Thanks for the info. The bike runs fantastic, and I appreciate your being open on the weekends. Your generous and flexible hours, allowed me get the ride to ya for a GREAT tune. Appreciate that.

Sounds as though there is a lot to know about the dyno business. And with the current lack of standardization, a given bike could produce 3 differant sets of results on 3 differant dynos. Interesting...

Best bet is to return to the same dyno, if monitoring results from ongoing upgrades.

Thought I would get this all in 1 thread.  Post your Dyno numbers on your SERG along with the basics to get there.  Dont have to post the graph.
  I had mine dyno'd today.  Was hoping to get a little more.  With the canned map, it was rich below 2500 and then went lean past that.  87hp and 105lb torque
after:
91 hp
111 lb torque at the wheel
   and its rich 1000-1800 then perfect fuel/air the rest of the power band.


Heavy Breather, Fullsac baffles, Super tuner, cat removed, triple plat plugs, SE wires.

I would appreciate seeing the type, manufac, Dyno and the core sizes added.
Thanks

Ahhh,  lets see, not really sure type dyno but here goes:

DYNOJET using WINPEP 7
1 3/4" Fullsac baffles

OK,

Tomorrow I will ride the Glide down to Lubbock (weather permitting) and Wild West will put it on a Dynojet. I would expect HP numbers to be close to the DynoStar numbers. However; I believe the TQ numbers will be lower than the numbers I have previously posted for the DynoStar I ran a week or two ago.

The primary changes to the bike were:
1) Removed the cat
2) Installed the Fullsac 2" baffles
3) installed Heavy Breather
4) Installed SE Spark Plugs
5) Good Dyno-Star tune using Super SERT


For now:

Dyno Star:
95.1 hp @ 4740 rpm
128 ft/lbs @ 2750 rpm

Today's results (10-25-08), from the DynoJet at the HD dealer in Lubbock,Texas..

Dyno Jet:
90 max hp
107 max ft/lbs

37 mpg today, on the ride home (150 miles)

it would also be helpful if the dyno showed the Air/fuel line as well as letting us know if it is SAE. much appreciated.

[sblair]

My dynojet sheet showed the air/fuel for the 1st run and last run.  Big difference!  It was running below 12 up to 2500 rpm and then went immediately lean 13.5 till 4300 rpm then back to the rich side.  Base line is 13.  Final run dips to 12 between 1500-2000 rpm and then pretty much baselines at 13 rest of the rpm scale.
   What is SAE??

Stock motor w/Stage I, no friggin way! Get that torquemeter recalibrated!!!

Hoist!

DITTO BRO !

 

Obviously these numbers don't mean much, attributable to the fact that there are no real compliance "standards" or "testing measures" required in order that comparisons can be made.

How unfortunate, I had hoped that the industry was a little further along than this, but "It is what it is". GUMBO!

[skyhook]

of all the forums I frequent, IMO this is the dyno reporting concensus:  on '07 and later h-d's, 5th gear sae on a dynojet 250i on pump gas...be transparent and if it's a different dyno manufacturer or model, disclose...give run conditions(temperature, barometer, date, etc)...if all these things are given, we ALMOST have a level playing field...that said it's best to look at similar builds with repeatable numbers, not the highest or lowest example, run, etc...and finally dynos are intended for tuning, not bragging rights...rant over

[partycrasher]

show air/fuel line as well.......

Hi to all.  Finally got my heavy breather delivered and installed it last night.  Just back from the HD dealer and dynojet.  They used the SERT but claim to have some way of keeping it from HD.  I now have a computer "Key" w/ the software.  Starting numbers with mods but pre tune were 85.02 hp and 99.74 torque.  Final numbers:  89.07 hp and 109.22 torque.  These starting numbers were not "stock" but with:

Drilled out CC
Installed:  2" fulsac cores
              SE Plugs
              HD heavy breather

The curves were good with a lot of usable power from 2K rpm's to 5500 where the starting numbers really fell off after 4500.  I was very lean to start with an A/F above 14 through out the rev range.  Now, I'm right about 13.9 - 14.1 and it richens as the rpm's rise.  The tech is supposed to e mail the print outs to me and I'll post when he does.  Should be running much cooler now.  It's a cool day here so it's hard to tell but I think so.  It sure feels better!  Mod on!

Like was mentioned above, if you guys start compairing tunes, you should also include you SAE correction numbers, these will make a big difference in the TQ/HP numbers.

wow, nice.   all that out of the 110?  Let's Roll
