Vance and Hines Power duals, Zippers Max Flow aircleaner and power commander added to my Ultra netted 92 HP and 107 torque. I am very pleased with the ride results. It just keeps pulling, just what I wanted

[jonandflo]

I have ordered the Vance & Hines Power Duals (16759) for my 2009 SERG. I will be using them with Rush slip ons with either 1.75" or 2" baffles. I plan to start with the 1.75" to see how it sounds.  If I increases the size it will probably be to the 2.0" on the right side only. That is what Rush recommends anyway since exhaust flows aren't evenly distributed with the 2009 type exhausts. I have waited to install this because I wanted to finish the break in on the motor, and I'm still waiting for the Thundermax auto tune ECU for the throttle by wire touring models to become available. Zippers has told me that they will begin shipping in June. I really can't see using a non-closed loop system, like the PCV, and a dyno tune. Dyno tuning is punishing to the motor, and only achieves results that wotk at that atmospheric pressure, that altitude, that intake temperature, and that exact setup etc.. After you've done it twice you've already spent more than the thundermax anyway. Its a no-brainer to use the closed loop system like the Thundermax. I'm a bit reluctant to try the Terry Components closed loop add-on system because it uses only the rear cylinder narrow band oxygen sensor. Its range of correction will be somewhat limited from the baseline HD map, and autotunes the front cylinder based on rear cylinder readings. The Thundermax claims a range of autotune up to 50% (although the recommended settings are limited to 20% overall with 5% per run cycle), and individually tunes each cylinder with wide range oxygen sensors. I'll let you know how it goes, and it will be based on real riding experience; Not dyno numbers. Isn't that what really matters? How it feels to ride the thing?

I agree.  Seems like the ability of a WB solution to tune is by far the best answer.  I had the ThunderMax on my 07 SE Ultra and it was wonderfull to ride.  Adjusted for temp, altitude, gas octane, humidity and other variables.  HD uses the NB O2 sensors to keep the steady throttle AFR between 14.2 and 14.7 (and thus appease the EPA).  My PC V with autotune and WB O2's is set to run 13.5 to 13.7 at steady throttle.  Bikes runs cooler and I have not had any reduction gas mileage (could be that it actually breathes better and thus runs better). 

No dyno tuning, just did a one time pass for $40.00 bucks to see where I am.  95 hp and 108ft-lbs.  I'm making no changes.  Runs great at 14000 feet or 600.  In the thirties or in the high 90's.  With 93 octane or 89 in Colorado.  Absolutely no complaints.

A buddy has spent a small fortune on dyno tunes and has no more power or torque than my bike.  He put his bike into open loop to get the afr where he wants.

Just got my 09 SERG back yesterday, I had the  V&H Power Duels installed, SERT, Heavy Breather, SE slip ons and had it Dyno tuned. Not sure if my results are correct, a bit skeptical after reading others results and by reading on the site here that some Dyno's give higher readings to make us happy. My results are peak torque 124.5 at 3300 rpm, and peak HP 98.75 at 5300 rpm. Big difference in the seat. Feels like the power is very useable and in the range where I can enjoy it. Very happy with my results and sound.

It would be interesting to see your dyno chart, if you can post it on here. Sounds like you have a very healthy torque curve!

Wolfman's dyno sheet

[RedDevil]

I put on the power duals, PC-V and Rush slip-ons with 2.50 baffles.  Attached is the Dyno sheet.  I am not impressed with the numbers  .  I had better numbers on my 06 FLHX 97 hp and 104tq.    I am still getting all the heat..  My SERG spent 3 days on the dyno and they put about 200 mile on it trying to get it right.  I am not happy at all with the performance  Now I have a hesitation when I first hit the throttle. The PC-V should work much better then it is.  I think the 2.50 Baffles are to big with the power duals.  I just ordered fullsac 2.00 baffles for the stock mufflers and then I am going to take my SERG to a different tuning center and see if I can get some better performance.

Those are actually pretty respectable numbers, if all you did was change the pipes and mufflers....I agree about the hesitation, but the numbers look good IMO.  Those are typical for the type mods you did.

I have had no issues with hesitation or heat with my PC V setup.  I agree that a different tuner might help.

Wolfman's dyno sheet

Just curious why Wolfman's dyno sheet for his '09 is dated July 11, 2006?

[wolfman]

I don't know why that date is there, was Dynotuned on Aug 11.

[Hotrod50]

Is our stock air cleaner on the 09 SERG enough?  I thought it was a high flow air cleaner.

[wolfman]

I've read on the site that it is high flow but the Heavy breather will pick up a little more power, 2-3 hp I think. The stock air filter is the ventilator.

I just ordered  a set with 4 inch slipons just put a woods 7h cams in it also bought fp3 tuner and already have the 117 upgrade done I will let you know in a few weeks how it all works out for me

Kind of an old (11 years) thread you dug up...Welcome aboard.  Interested in your results, just the same!
