my 10r dyno

The lack of torque is due to the scanner he used not picking up the line

the problem is he said it's correct.

i might do another one at bikini bike wash just to prove it.

that would be the same guy so no. unless he gives me credit for that and i pay the difference of what he charge the group.

Hrm... If it doesn't come out, and he doesn't do another pull for free I'm not going to be happy.

Id ask if I were you, that graph definatly isn't right. Could be a 'less expensive' alternative

**HBerry** · 07-08-04, 06:32 PM

A kid with a 10R with a pipe on it only pulled 10 HP more than Kham so it seems true.

this other 10r dyno chart of torque is more like it. at least close to 70.

http://zx-10r.net/forum/viewtopic.ph...highlight=dyno

either my bike is fucked up or the dyno is bullshit.

I did some calculations:
hp = (t*rpm)/5252

t = (hp*5252) / rpm

Using that chart above we approximatly get the following:
70tq @ 8600 = 114hp @ 8600rpm

We will ASSUME that your peak torque also occurs at 114hp. According to your graph that happens at 102mph.

Assuming the graph is 4th gear; 102mph = 8012rpm
I DL'd a gear speed/rpm calculator and used the stock sprockets, and tranny gear ratios

114hp and 8012rpm is what we needed:

T = 8012 / (114*5252)

At 8012RPM you are making 74.72 Tq

Its NOT physically possible for it to only make 40ftlbs if you are making 114hp at that speed/rpm.

Eg 2;
5252rpm is about 68mph going by the calculator, and thats about 64hp according to your chart. There HAS to be 64 Tq there.

**Kham** · 07-08-04, 08:31 PM

well there you have it, the scientific proof. im not bullshitting you.

thanks very much.

i wonder if the RJ guy will believe this and give me a free run so i can have it corrected on the paper.

**Kham** · 07-08-04, 09:04 PM

damn i dont understand the math. my head hurts.

**benVFR** · 07-08-04, 09:13 PM

Dude when you get the corrected dyno graph take it in to a shop and have someone tatoo it on your forehead!

It's the only way to get respect.

**Kham** · 07-08-04, 09:19 PM

yea i could just plot that with Excel.

Ben, i just feel cheated. i mean would you just take whatever shit number they sholve at you and not even have a clue? im not that dumb.

No prob, it was actually kinda "fun"

Print out what I did and show him, if you show up on the 1st, and they arent strapped for time, they may let you throw it on for free so you can get a good graph. You did pay for it after all.

What the fuck do those numbers REALLY matter anyway? I don't get why you're getting all worked up. Simply put, it's wunna the top dogs out there, PERIOD. What the hell does it matter what ONE dyno chart says? Seriously. I'm not trying to bust your chops here. But what does it matter?. It's a ZX10R fer chrissakes!

**Kham** · 07-09-04, 06:47 AM

what's the matter with you?

going in there with high expectation for the pros and the dyno machine and the numbers aren't right. what word of "feel cheated" you dont understand. not the same as all worked up. i said i wanted to try a dyno at bikini bike. you know what? forget it. i dont give a shit anymore. hows that?

**Stoneman** · 07-09-04, 07:46 AM

Relax Kham. As I said, I'm not trying to bust your balls. You have wunna the most powerful (EVER) production bikes on the planet. I don't understand why you're so concerned about what some dynometer has to say...

If it's the piece of paper you want in your pocket to show people, just tear an article outta wunna the moto rags to show...

Now if you're concerned because you're interested in getting a Power Commander and dialing your bike in for OPTIMAL performance at all RPM's (READ: NOT higher HP numbers), I can see your concern...

It's pretty obvious to everyone that's replied to this thread that their dyno was a bit off on the tourque numbers. There's even been a scientific explanation for it!

Again, anybody who knows anything about motorcyles KNOWS what the numbers are for that beast...

Personally, I could give a shit either. Just wondering why it's such a concern of yours that THEIR numbers were off. You KNOW what the bike is and is capable of...

**Stoneman** · 07-09-04, 07:50 AM

Oh, FYI: Usually these 'travelling dyno HP shootouts' are meant to measure HP only anyways. If you were paying a shop their going rate for a 'dyno tune', THEN I'd be concerned. But to do so, you're usually looking at considerable time on the dyno...

And Dynojet will NOT sell their dynometer to ANYONE unless they've been certified through THEM...

Not on a stock one.....

And Ben, 230 HP........

**RevHappy** · 07-09-04, 08:59 AM

Kham If this means anything to you my bike got dynoed on the same dyno as yours did and mine came in 16 LESS horse power then the previous 2 dyno runs at other locations...I'm going out on a limb here...... BUT.....I think the dyno numbers are low on that dyno machine on purpose.....I think its a ploy to get all the horse power junkies to spend money at there shop because they have to have 160rwhp because thats what the bike is supposed to have. "Wow your pipe & jetted R1 only makes 130.68 rwhp your jetting must be off" Hmmmmm fishy.........just made 146 the other week and there is no stumbles.....hmmmmmm

**benVFR** · 07-09-04, 09:36 AM

And honestly...

What does the bike weigh with a full tank of gas? 433 pounds?

You could still speed like a maniac on it even if it only had 50hp.

Ben

I can speed like a maniac and I only have 48hp at the crank!

although I suppose "speeding like a maniac" is pretty relative

Kham - I can understand why you're peeved but I hope it doesn't take away from the enjoyment of that beast of a motorcycle you got

I still don't think it's accurate.... I trust the Kawi numbers more than a 2 minute run out of a trailer...

.... I trust the Kawi numbers
"not me"
dynos machines R also man made
if god made a dyno
i would trust his & his only
i was on your bike kham
"put my nuts on your tank" & i was verry inpressed
& like i told you

ps my balls dyno rated it @ 164.596 @ 11,780 &
torque 80.1 @9,800
hope this make you feel better
who you trust some 25 $ dyno or my nuts

**Kham** · 07-09-04, 12:23 PM

thank Squid.

i guess i trust beets' ball more.

his balls over my math skillz

The HP curve is fine, and its just a matter of getting the Tq out of it. If he says the bike only makes 40ftlbs, period, no matter what. Then he just started breaking laws of physics. World is ending, game over. BAM.
