That was the unusual and interesting part of this exercise Howie.  It really was three bikes from three different parts of the country all on the same dyno ran by the same very experienced guy.  That type of comparison is something we're rarely allowed.  Still only a curiosity.  But a good one.

Thank You!

Glad you got it taken care of before there was an issue!
More money, more money, that will take care of it.
With all the bikes you have, you have to be insurance poor!

 

 Not Really, Have Geico &  It's about 1700/Yr..The extended Warranty covered all the stuff on the Glide except cams...

That bearing change was about halfway through the 2000 model year.  Got any idea whether blues or reds came first that year?

Had to be the REDS....they are always Faster.......

Ok Robert, here you go.  Sandy just emailed me the three bike dyno chart.

Unfortunately she apparently doesn't have the final run with mine.  This run was part way through before we stopped for me to replace an embarassingly nasty air filter I'd not noticed and put in a new clutch spring to get rid of that dip that starts about 3200 and dives through 3800 or so on this run.

Looking at the torque curve: With the new air filter and changing the clutch spring mine started just about the same in the 2500 range, didn't get the dip at all and climbed to what'd be just about an even track with Chip's from about 3500 on.  His wins out by a point or so (yeah Blue bike !!) but it's interesting to see two very similarly equipped bikes in fact do two nearly identical runs.

The HP curves were about the same story.  After the filter change you could almost lay the two lines on top of each other.

Yours is only a bit down from there Robert.  10%-ish.  That's not a problem.  It's just something to look forward to whenever you decide to mess with it .

Sorry Don, you're 100% correct. I didn't go back and look at the whole thing before. I must apologize to all for my incorrect previous statement, based on Golden tuning ALL of the bikes. It's still not completely accurate with them all being tuned at different times, locations and weather conditions, but better than completely different tuners and dynos too. And so ya'll know, I was kinda funnin with ya'll though and wasn't very serious. After all, what do I really care!

Hoist!

Sure thing.  Never even thought about it.  And like we said above, it's just an interesting curiosity.  No matter how alike the runs are they're still not identical.  Was a nice and fun comparison that we don't usually get to do though.

Even though there are always difference I was really surprised by how very similar Chip's blue bike and the other red bike's final run were.  I've only got the numbers spreadsheeted and Sandy didn't have the very last run saved.  But those are bikes that are similarly set up right now and produced runs you could almost lay on top of each other.

That's good to hear. Couldn't ask for a more capable guy to be doing them all.

I've got an interesting comparison to post when I can get my sheets posted. One shows a comparison between a stock '08 Stage I SEUC plotted with my WOT run. Mine doesn't yield very much more max torque. But mine's everywhere (flat curve) with the HP to match it. The stocker is a dog and only makes that TQ for a short duration and starts later. That's what Brian's talking about when he inquires about speed. I've got a few interesting charts and pics. They'll be up by tomorrow!

Cool.  Looking forward to it.  The raw numbers themselves don't mean a thing.  The comparisons can be very informative both for just before/after changes and for diagnostic purposes.  That is often very good data without regard to what the numbers are that lay over the of the runs.

Now the next time I can find Mr. Golden we can try to give it another whirl.
I changed the ProPipe for the Fatcat.
That should be an interesting comparison with everything else being the same except for the pipe and the tune.
What's the bets gonna be?
Better numbers with the FatCat or the ProPipe?

I'd remembered incorrectly.  Thought you'd already gone to the FatCats when John had spun yours.  If not then our final spins were very very close to each other while having similar but not identical exhausts.

Bet the FatCats bring it in a little earlier.  You'll probably still be on top of the other red bike but it may not be in earlier any longer.  That was the most important difference the butt dyno told me when the FatCats went on.

I am planning to go gears in the next year also.  What cams are you considering, Don?

Not in to the question far enough to know for sure yet Robert.  Know it's a winter project.  But that's all I know for sure right now.

If I can convince myself to touch up the heads at the same time and use slightly heftier springs I'd have to at least consider Dave Mackie's 590 cam.  It's hard to knock Mackie's efforts. 

That cam is also the slightly smaller sibling of the 598 that is working so well in the red bike.  Truth is I don't have a clue yet what I actually will use.  But for those reasons the Mackie 590 will at least be a consideration.

[RobertinArgyle]

If your changing the cams it sure is tempting to do the heads also.  I'm sure that would be the best bang for the buck.  Thanks for posting the graph!

And there begins the slippery slope.  If cams why not touch up the heads.  If the heads are off why not flow work.  If really working the heads why not head and piston combinations with the cams.  If the cylinders are off anyway why not drop on just a bit more displacement.  Do that might as well throw on a throttle body and a fuel pressure regulator to make the Marelli drink a little easier.  Damn, those cheap chain tensioners get expensive fast.
