Post Dyno Charts Here.....

[SpicyMchaggis]

I don't know about you guys, but I have like 120whp on my VN900C. 93 octane adds like 80hp right?

No.........Use Jet Fuel for that..........

I have a 900 custom with the Barons BAK, pipes and the pcIII,i'm running the advanced maps that are accessable from the Powercommander website ,shes of to the tuner on Tuesday to have some custom maps made so i will post the results Wednesday cheers

Here is the dyno results for my 900 custom (pipes pcIII and barons bak)i don't know how clear the pic will be but the figures read max hp = 51.71 max torque = 57.25 ,the guy doing the tuning was surprized at how rich the 900 was running

Thanks for posting a 900 with all three mods, air/EFI/pipes. I am assuming that the dyno you posted is the "corrected" version since I do not see any references to humidity/elevation, etc. I am surprised that you did not post the sheet that shows the air/fuel. And since you have the PCIII that they did not adjust it to bring it more to their liking. But then again the curves are pretty steady and leaning the air/fuel may not have improved performance. Did the tech say anything about that?

So it looks like adding the EFI ($300) and pipes ($400-500) added 3 more hp and 3 more lbs/torque compared to just adding a BAK. Well you just confirmed that is $800 I don't need to spend....

The dyno for my bike also showed it running a little rich but not enough to hurt anything and checking the plugs 700 miles later confirmed that. Compared to my posted dyno is your 900 running richer?

how come bluemeanie made so much more HP with an 800?

Hi i'm not up to speed with dyno sheets but i believe they were corrected ,the data at the bottom of the sheet refered to humidity/elevation etc etc i choose not to post the last section as it had my personal details at the bottom,the results that are posted are from new maps that he built for the bike,i guess it would have been interesting to compare them with the old results but i didn't bother asking for before and afters.
The bike feels very strong through its rev range now,maybe its me trying to justfy the $$ spent but she does feel very good,all in all very happy with the mods so far.My 900 has done 2200 klm cheers

Ok, let me see if I got this straight. According to the dyno tech your bike was setup running rich with the PCIII. He made appropriate adjustments to lean the air/fuel and the run you posted was the results of the adjustments. Is that correct? So now your bike is pretty much at the correct air/fuel ratio? Over here they do a corrected and uncorrected run. Corrected compensates for elevation, temperature etc. Uncorrected is real world results for your bike at that given time and place. If it does not say you might want to call and ask. My uncorrected results were an additional 1 hp and ft/lb of torque. I posted on this thread some factors that affect dyno results, i.e. a bike with 6,000 miles compared to a bike with 1,000 may show a 10% increase in power. Running synthetic oil can improve the performance 1-3%. Also a lower drive ratio can change the output (adding a Scootworks pulley for instance). Here is a link that I also posted in this thread that talks about some of these factors.

Again thanks for posting. In this thread we now have a dyno for a stock VN900, just a BAK (& Scootworks pulley), and yours with BAK/EFI/pipes. It gives folks something to think about.

And since Mcvulcans bike is an overseas model, does it have different EPA stuff? or is that a moot point? Something bout all these dyno sheets doesnt look right.

Read that link I posted it might help your confusion.

McVulcans bike has all new BAK/EFI and pipes, I have no idea what EPA stuff would be there.

Also bluemeanie's 800 showed lots of HP but he did not post the torque. I suspect that is the downside of his bike. HP is just lots of rpms.

Thanks. read the article(several times!) Ill stick to the seat of the pants dyno here. I spent a lot of money on pipes efi air etc and love 1. the performance gains 2. the look and 3. the sound ive achieved. I know a 900cc bike will never be a V2K But its what i got and i enjoy it thouroughly. Kinda wished id never stumbled in to this thread though! Oh well thanks for the info. post all the dyno charts you guys want i for one will not be back to this particular corner of the forum! too disapointing....

One more 900 Custom dyno to add to the mayhem. This one is the Custom with a Thunder Mfg. Teardrop Air Intake and a PCIII run in 4th gear. Corrected output as follows:

Max Power - 50.42
Max Torque - 53.09

I'm using map #1 from the Dyno website. The tech said I could do some minor tweaking to smooth out the curve a bit but it wasn't necessary as the air/fuel ratio seemed decently in order (sorry, no visual posting for that). Beyond that, I'm not gonna be able to give you too much more info.

i dont have a scanner(working on it) but i got a free mobile(inacc) dyno run yesterday. i have an 07 mean streak with caddman intake, cobra fi2000, and road burner 3" drag pipes...

hp - 62.61
tor - 81.34

Congratulations, you are the 4th 900 to post a dyno. Nice run and it is looking like we are finally getting some consistent results. So you are running Thunder Air/PCIII/stock pipes. Your run is very consistent with mine(BAK/scootwks pulley). You pulled 2 more horses and I got 1 more ft/lb of torque. What is encouraging to me is that the rpm range above 40 hp and 40 lbs of torque are very consistent between the two bikes. Yours is looking like 40+ hp from 4-7.1k rpms (mine was 3.9-7.1k) and your torque was 40+ ft/lbs from 2-6.4k rpms (mine was 2-6.3k). These are a much greater rpm range than was observed on the posted stock 900 dyno.

This also confirms to me that bang for the buck, of the three, air/EFI/pipes, changing out the air intake provides the most performance increase.

Hey, it seems most dynos do their run in 4th gear but this doesn't seem right for cruisers??? We spend WAY more time in 2nd and 3rd gears - shouldn't that be the gears they do the run in?

[kerrdj]

i thought dyno runs had to be in direct drive or closest to it. you arent measuring what the trans does but what the engine does so you "attempt" to take the trans out of the equation(correct me if im wrong)

Which pipes did you install?

Wish me luck. I'm heading to pick my bike up from the Dyno. I'll post the img in the pm

Not sure what I had without everything on it but it lookes like I pulled:
62.81 Torque
58.98 Horse Power


Power commander III
Cobra Longs
Thunder Pro-R Hypercharger
