Heres another with just ac pipes and a PCIII, oh and little time in the dyno with Tuning Link.

[Jim Kerr]

To catch everyone up, I've done some updates to the bike.  I've removed the catalytic converter, I removed the OEM baffles and replaced them with 1 3/4" Fullsac Baffles and I have applied the a standard Race Tuner map (no tweaking yet).  The air intake and everything else is 100% stock. 

We Dyno'ed it today and I'm now pulling 86.2 HP and 105.0 torque.  This compared to the stock numbers of 78.3 HP and 90.9 torque.  This is proof positive that the stock pipes are highly restrictive.  I've increased my horsepower by 7.9 and my torque by 14.1 by basically changing the pipes and coring the cat.  Not bad for a couple of hours of work. 

Next up we're going to spend a couple of days optimizing the tune on the Dyno.  We should be able to get a bit more out of her. 

Here's the graph of today's run (Blue Lines) compared to the 100% stock run (Red Lines).

Looks pretty good.  I changed my pipes to 4 inch HardKrome with stepped headers from 1 3/4 to 2".  The rest was A/C and Race tuner and my results were 90 HP with 112 Torque.  So yea, just changing those stock mufflers will make a huge difference.

Very respectable increase for the efforts, Nice Work !

No doubt.  An increase of 7.9 HP and 14 lbs of torque for a bit over $100.  The exhaust mods are the cheapest thing I've done to the bike. 

You're up next.  Can't wait until you dyno yours.  It will be interesting to see what the Heavy Breather will do to these numbers.

Well, can't wait to get on the band wagon. The local HD dealer had their Dyno down this past week, but was working with a tech over the phone to get it running. Said to call back Wed and may get me in this Saturday. If not I will attempt a ride out of town, weather permitting. Just a straight base line pull with no tune is not terribly expensive.

I had planned on the out of town trip to Edmond to get on their dyno last Saturday, when I discovered the breather bolt problem on the new Heavy Breather. Temporarily replaced with stock air box. I missed the dyno appointment as it took most of the day troubleshooting and cleaning up the mess.

While the stock breather is on, I'll dyno as is and make another pull with the new breather the following Saturday.
So pending some other surprise, I should have dyno results, stock with Fullsac cores Saturday night.

OK gang, I got my bike back today.  We were able to get a bit more out of her.  We are now at 97.4 HP and 114.0 TQ with the 1 3/4" baffles!

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

The 1 3/4" baffles are indeed choking the engine and is taking away some HP.  We can see the engine being held back using wide band O2's.  I'm going to install 2" baffles and do another dyno tuning session as soon as I can.  HP is good, but torque is better for my riding style.  I'm hoping the 2" will give me a bit more HP without loosing too much TQ.

FYI, the attached graph is before and after the plug change.  We got a bit more out of her by using more efficient spark plugs.

Hi Jim,

what a/c system did you go with,the stock one from the cvo glides was'nt good enough?

thanks

Jon, I went with the SE Heavy Breather air cleaner.  The one on the bike was good, but not as good as the Heavy Breather.  That thing made a big difference in performance.  It also looks cool.

Jim is that the a/c that has the 90* bend in it

because it won't work with the lowers,haven't really found anything I liked thats why i was going with the a/c from the r/glides liked the look

any a/c sugestions for a cvo cuse4

thanks for the help on this and what you have done for the rest of us,as soon as the parts get here I will be doing mine

get ride of cat
monster ovals(09 models should be here any day)
cvo r/glide a/c

Yes it is the one with the 90 degree bend.  It will work with lowers, but you have to remove the right glovebox.  I have lowers on my bike and it fits.  The stock breather is a good one.  Not as good as the heavy breather, but it does the job.  You can certainly keep it.  You will just loose a few HP. 

[planenut]

thanks jim

do you think that it is the element or the whole set up that is the problem

can you show a pic of yor filter anyway

Jon

[Iglide]

Great News Jim!

[Iglide]

Jim,

Did you have any crank case/oil temps, before and after?? If, your mod.s would keep the temps below 200 F, that would be a major plus for reliability issues.
