Post Dyno Charts Here.....

[Renegade900]

Rod2625, you might want to check out the new Vance&Hines Fuel Pack... it can add and take away fuel... Might be a good alternative for you... haven't heard of anyone using it yet, but it sure does sound like a sweet unit... and of course Vance&Hines knows a thing or two about fuel/air ratios...

Hi, I'm new here and am going to be putting on new pipes, looking at the Vance and Hines Slash Cut Staggerds, will be adding a PCIII and not sure on the air filter yet. I have already done a little research, that is how I came across this site. Have been reading and it sure is a great site for information!!

We were talking about what the results COULD be on the Dyno so I was pretty excited to find this thread! I printed out the results of the Thunder Mfg reading and will show it to him.

Anyway, I have a 2006 Vulcan 900 Classic LT. My question is, after talking to my friend who owns a local MC shop and will be doing the work on my bike, he suggested I go out and ask about the air filter on the stock 900. Is it capable of handling the extra air intake that will be needed or do I NEED to get a different one? From what I have been reading, it sounds like the most popular and most effective is the Thunder Mfg filters?

Thanks in advance for any input on this subject. I have been riding for a while now, this is my first cruiser and I have almost 12,000 miles on her. My husband has a Gold Wing and when we ride, I would like just a little more than what I have. I don't really want to get a bigger bike right now, would like to try this route first!

(Thanks, by the way for the post of all the different pipes and how they sound, that was pretty cool! I may be changing to the Cobra Speedster Slashdowns......

I have not seen any "rider" posted dyno results on the Thunder Air Kit. Quiet honestly I am a bit skeptical coming from the manufacturer. From a looks and sound prospective I think it is hard to beat the Baron's BAK. And if you look at my posted dyno you will see that compared to a stock VN900 it gave me 6 more hp and 6 lbs torque (about an 8.8% increase). That is without changing the EFI or pipes. Most folks will say the stock air intake is very restrictive.

The recent Cruiser magazine had an article on adding "performance" pipes on a Victory. The manufacturer never tested their product on a dyno yet stated that by adding their pipes you would feel improved performance. Well, the test of the stock to provide a baseline and then adding their pipes and EFI showed worse performance in hp and torque. By opening up the air intake they were able to get some gain over the stock setup. Apparently this is consistent with testing done a couple of years ago on several other popular pipes.

I think most of the VN900 owners here would love to see the dyno results from somebody that has added an air kit, EFI and pipes to really see what difference it makes on this bike. Quiet honestly I am very happy with just the BAK. I don't feel I need more hp and hate to spend money to replace something that is working so well. You won't see any better/smoother curves posted than on my 900.

Good luck, and you might want to check out that article I mentioned.

Quote by you in an earlier post....A lot of 900 owners are waiting for somebody with air/EFI/pipes to post a dyno to see how they compare.


rod2625,

Thanks for the response. It sure has been interesting reading all of this information. I am excited to see what the outcome will be myself. I appreciate the feedback and will post the results here, although it may be a little while. No hurry right now to get it all done. Up here, there is snow on the ground starting in October and we can't ride until usually the second week in April at the earliest! But I promise I will post the results because I do plan on doing it all.

Can't thank you enough, this is a wonderful site!!

Glad to hear that the setup you did worked so well for you....

ok im looking for a dyno chart for a 900 with pipes pcIII intake anyone know of one

[meanmother57]

heres a dyno chart of my meanie, hasmuzzy 95in kit,ported heads and intake,tfi fuel processor,caddman filter with k/n extreme top outer, shaved 10 thou of heads for compression of 10 3/4 to one,muzzy replica exhaust , made 96 hp on dyno and 102 ft lb of torque .

I use it with the PC3 and HK 2:1 sideburner. My dyno results are on page 1.

I love this stuff. The only reason i stated what i believe is to be true is when the person with a pulley (do not recall name) said as he was going up a hill he could feel the bike begin to strain at about 55 mph. That confirms to me what i thought would be a difference with the pulley. My bike even with a passenger wants to go at 55 up a hill in 5th gear. The shift points are not spread out, the motors power range is just moved up with a loss (even so slight) off the line. NO BIG DEAL JUST PART OF THE COMPROMISE TO HAVE LESS RPM IN 5TH GEAR AT 70 MPH.

What i would like and i would buy. Kawasaki has to update their line of bikes. That is how they stay in business. One day soon they will upgrade the 900 to something else. It would be nice if they would build in a wider ratio 5 speed in the 4th and 5th gear in order to reduce the highway RPM.

I'm finished.

Thats what I have on my VN900 - Hard Krome 2:1 sideburner with the BAK - if only I could find a dyno shop now.

I'll post the results if I ever get the tests done.

You did not tell us where you were but from here you should be able to locate a shop to test your bike:

I'm in the big town of Hobbs, NM. I actually looked-up one of the Harley dealerships in Odessa and their website shows that they do - so if I ever get down there I'll get her tested.

VN900 Scootworks +2 pulley, Baron's BAK, stock pipes
48.41 hp (8.80% increase over stock dyno)
54.11 ft/lb (8.89% increase over stock dyno) (wheel)

How is this an 8.8% and 8.89% increase?

I get this - where X is the percent increase:

42.62 * X = 48.41 --> X = 48.41/42.62 or 1.135 or 13.5% increase

or you can do it as a percent change

(48.41-42.62)/42.62 --> 5.79/42.62 = 13.5%

Similarly, I get 12.4% increase on the torque.

Just curious.

Too many years out of school or not enough coffee....I stand corrected

[06Streaker]

Here is mine for an '06 Meanstreak after adding Muzzy Megaphone exhaust, Forcewinder intake, and PCIII.

[rod2625]

Very nice looking run...very smooth, A/F looks great! You should be very happy. Have you gone back to look for a dyno on a stock MS to see how your performance mods helped?

You know we are never happy! I haven't found a comparable dyno for a stock meanie and although i'm curious, I wasn't willing to pay for another dyno run to find out. However, i'm installing a big bore kit now and will also be porting the heads and intake. At least now i'll have something to compare after these mods are complete. I will post those when I am done as well.

[rod2625]

The more I look into this the more I am realizing that it makes no sense to try and compare dyno's from one bike to another. There are too many factors that come into play as I am finding out. On this thread are two VN900 charts:

May '07 posted dyno of AntiGenX's STOCK VN900 Custom SAE Smoothing 5
42.62 hp,
48.12 ft.lb (wheel)

VN900 Scootworks +2 pulley, Baron's BAK, stock pipes, SAE Smoothing 3, Corrected. (same bike below but uncorrected results)
48.41 hp
54.11 ft/lb

8/28/07 11:48AM Run Type: RO Run Conditions: 76.10 degrees F, 30.06 in-Hg, Humidity: 35%, Uncorrected: 1.00, SAE Smoothing 3.
Max Power = 49.44,
Max Torque = 55.19
(These numbers are real HP/Torque for my bike for that given day where it was tested).

I found a reference to a dyno test on a stock VN900 from Motorcycle News, Reviews, Videos : Motorcycle.com
Max Power = 47
Max Torque = 53.4

We do not know if these are corrected or uncorrected numbers. But much higher than posted by GenX and I did find reference to a Aussie that only got 39HP on his dyno run. My understanding is that corrected makes it more apples to apples, compensating for elevation, temperature, etc.

"Correction Factors are used to compensate engine horsepower measurements for differences in operating conditions during engine testing. The typical correction factor (CF) is calculated based on the absolute barometric pressure, air temperature and water content of the air used for combustion by the engine under test. It attempts to predict the horsepower that would be developed if the engine were tested at sea level under standard pressure and temperature conditions."


Some of the factors that affect readings are:

"Pure synthetic oil can easily show a 1% - 3% or greater increase in horsepower compared to conventional petroleum based oil." (I was running Amsoil)

"An increase of nearly 10% from power readings done at 1,000 miles to readings taken at 6,000 miles." (GenX only had 600 miles on his bike).

One of the questions I had was does the Scootwks pulley affect the results and the answer is:

"One of the most common differences when conducting roll-on power tests on a dyno is in the gear used during the test. Although fourth gear is the “de facto standard”, some dyno operators prefer to use fifth gear, which can distort comparisons. Power readings recorded in fifth gear are generally higher than those performed in fourth gear. Also, a lower final drive ratio such as 3.15:1 will often show a higher power reading than a higher 3.37:1 ratio. Generally, the lower the transmission gear or final drive ratio, the greater the engine loading and higher the power reading will be. Since the lower gear ratio slows the engine’s acceleration rate, less power is required to accelerate the rotating and reciprocating parts."

So for those of you that want to read more on this here is that link I was quoting:
