Dyno results?

[rufusdion]

OK i havent seen a thread about this yet.
Would like to see dyno results from everyone out there who has had there bike dyno'd. be interesting as to what bike are getting what figures.

Please post your mods on your bike as well!
cheers

What is it with dyno results? All that my bike pulls harder than your bike is a load of wank factor. What's wrong with getting your bikes out on a track and see who has the biggest balls and the best skills?

Quite right. All the power in the world won't get a goose around the track.

[Angusdog]

Plus I was lead to believe that results on one dyno can't be compared to another, i.e. they're principally a means for testing one bike against another on the same dyno or comparing to the same bike pre any mods on the same dyno. Dynos vary in type and operation so the figures don't provide an ultimate "this is the power this bike puts out" figure. For example, atmospheric pressure (the weather) affect the results from day to day.

[bucket boy]

dyno nothing to do with wank factor after youve done work on machine you want to no its running mint not to rich or worst burn a hole in piston

Surely not all motorcycling is about a race track :blink:
"See who's got the biggest balls on the track..." sounds like more of a "wank" to me but hell....each to their own eh.
Some people have simply worked their arses off to buy some after market goodies for their bikes and are after the results.

100% true...

So isnt the point of aftermarket goodies to make your bike faster? What good is a piece of paper saying your bike pulls harder than everyone elses if you cant use it?

[DMNTD]

The point usually is to make your bike RUN better than stock.
The piece of paper is to show where and how it does this.
Anyway....what's wrong with making you bike run faster that what it did originally? Most bikes could do with a dyno run...

[Goblin]

I dont think theres anything wrong with making it faster but most people(you not included) would never be able to use its full potential stock standard anyway.

That's what I was trying to say. The dyno is only part of the picture; a well put-together package will outrun (on the track, the strip or the road) a stocker without huge power. Good suspension, brakes and tune-up work wonders for the overall performance of any machine.

Too many people get sucked into chasing the big figures without looking at the peripheral equipment but it IS handy to know what you have if you're in a competitive situation.

There's no point in putting big hp into the wrong bike or the wrong hands.

[MotoGirl]

K6 GSXR1000

heaps of stickers,

And how many of those came from the stickers? :bleh:

My K4 1k only had 145hp and its only mod was a Yoshi pipe.

[nodrog]

bummer, no wonder it never went over 80kph.

:girlfight: I got it up to 140 once (on the track even, how shaaaaaaaaaameless). It had like 140hp I wasn't going to use...

So we shouldn't post dyno runs so as to protect the suckers from themselves?
It's ok, the auntie helen will do that for you.

[Goblin]

Are we talking 'special olympics' ? cos you know what the result will be if you win ? G.No gazza. I just dont get why people feel they need they have to prove how many ponies their bike has. Like MG says her bike only had 145hp but she only got it to 140kph. What is the point of knowing how much hp if you cant use it?

I can understand it in a competitive scene where you might need every pony you could get but for road riding?

[Ralph]

Aaahhhhh so thats the secret, I need stickers :slap:

I would like to get mine on the dyno at some stage just for interest more than anything else.

I think its a normal bike rider thing as far as I can see. I have built my bike into something a bit better and although i haven't been on a dyno , just knowing it puts out X gives me a buzz. Then when out on the track you can spot the difference as well. Maybe its a bloke thing ? Gaz.

Im glad you and others get a kick out of knowing how much cos i get a kick out of you guys comparing.

[sidecar bob]

I got quite a kick out of spending two hours on the dyno with the sidecar getting the mixture & timing right & taking it from 187 rwhp to 227 rwhp, thats the best 168 dollars i ever spent.
I guess thats the difference between a NZ champ & an also ran.
If dynoing bikes is for wankers then bags not be the one to tell Sam Smith, Andrew Stroud & Shaun Harris etc that they are a bunch of wankers.

Nasty angry little piece of crap aint she, Just cant help herself from commentating on topics about which she has no idea, & the only reason her ZXR goes any good is because i fully sorted it out at my own expense.
Grab the popcorn & sit back guys, this should be good!!!

[ozrobo]

so you dont like to be competitive on the road i sure prefer to have my bike running well as it can and still beat them cafe racers up the mountains dyno dont sound like a bad idea

227hp from a relatively stock Hayabusa is doing ok,


we don’t bullshit about what is inside our engine – we’ve stated fact, that all we have is Wiseco pistons (of original cc). No hot cams, no rods, no trick crank, no oversize valves

I'm sure Scrivy wouldn't bullshit us :bleh:



Its bizarre that you imply we’ve got the most horsepower and that’s how we’re winning races. In fact, the Prentices would have the same, Dave Annan would definitely have more

I think he needs to retract those comments :lol:

Like I said Kick, it is standard - but for the pistons. A standard turboed engine is still standard inside isn't it Kick??
Our gain was from the outside, and not bolt on engine bits either - rather a modified Mr Dobalina piece of sheer f@rken brilliance!! That's what gave us the edge, and the ease of the championships. It's not (always) the dollars that buys you the championship, rather your expertise in your field. Mr Sidecar Bob is a f$%^$'n legend with fuel injection systems! Just look at the difference in HP figures pre and post dyno runs!!
I'd trust him with me life I would!! But wouldn't leave him alone with me misses!! :whistle::innocent::no::eek::lol:

As for comparing sizes....... I've only got a small one, so thats why I need big HP!! You know the saying..... Hummers - built for guys with small willys.....:bye:

Ok, we did it backwards, just to see how we were doing.

Not a bike but the theory is the same.

Our race car did X on the quarter. We had an Isky slide rule and worked out that to do what we were doing would equate to Y hp/ Z torque, ok? So, we hoisted the engine, stuck it on the dyno and discovered that what we thought we had, we actually had. The point being; the slide rule was right and so was our tune up.

We expanded the combination, broke some shit, learned a lot and got it sorted in about two seasons, one of which was devoted to the handling package alone. The dyno isn't really a requirement any more, it's superfluous to the application but there are many applications to which it is vital to stay on top. Naturally aspirated engines are sensitive to change, be it atmospheric, mechanical or otherwise but I'll say it again; all the power in the world won't help a goose.

Dyno'ing an engine is only any good if the operator of that engine knows how to operate it.

[The Stranger]

but I'll say it again; all the power in the world won't help a goose.

What with the sidecar boys slugging it out and trading insults and innuendo. Goblin and Sidecarbob getting all sexually frustrated and peasea repeating himself over and over it's actually getting quite interesting - I almost hate to bring it back on topic, but here we go.

Standard 06 FZ1 with a PC3. Now to alay any concerns the PC3 was fitted specifically to remove the throttle snatch these things are well known for.

[rufusdion]

Thats not bad STRANGER.My mates just brought an 04 FZ1, i show him your dyno chart as he is curious to have an idea what sort HP FZ1s have.

[nodrog]

Now to alay any concerns the PC3 was fitted specifically to remove the snatch.......

its not like you to be getting rid of snatch Noel.

[NordieBoy]

I like the dyno as it shows you some numbers for any changes you've made.
Wether they were for the good or bad.
Numbers to compare with your own previous dyno runs on the same dyno.

Can't wait to get some numbers on the mighty XR.
May even be into the 20's.

[NordieBoy]

Quite right. All the power in the world won't get a goose around the track.

They go pretty well for a 350.

[speedpro]

Dynos are good diagnostic tools as well. Plus in my experiance they are remarkably similar up and down the country as far as readings go. Most software takes into consideration any factors that will alter the readings, like atmospheric conditions. At No 1 while looking for the reason my bike was running like shit and REALLY hard to start I got 175hp at the back wheel. Sorry - can't find the chart.

[vifferman]

Dynos are good diagnostic tools as well.
From what I've read, they're usually run with the bike in third gear, and full throttle. Is that correct? Can they be used to set fueling at lesser throttle openings? The VFR basically goes OK now it's got a PCII back on it, but I've been considering a dyno run not to see how much power it's got, just to get the air/fuel ratio better in a few part-throttle areas below 6k rpm.

[NordieBoy]

You can run them how you like.
My bike they ran in 4th gear (of 5) and it hit the limiter out at 140 odd kph.

The fuel map can be set for various throttle settings and over a wide range of RPM.
In the map below you will see that at 5,500rpm on 5% throttle they added 26% more fuel. At 7,000rpm on 80% throttle they removed 14% of the fuel that. The PC interpolates values for combinations not actually displayed.
This is a portion of the map I am currently running.

When I got my 600 dynoed earlier this year. It gain a couple horses up top (That I can't really say I've noticed) but more importantly my mid range increased tons and the power was so much smoother.

This was done with runs from around idle up to redline. Also adjusting for different throttle positions at the same rpm.

Numbers wise this gave
107BHP with Yoshi TRS Can+K&N
Obviously this is relative to the dyno

[HDTboy]

Yeah I saw that. That's why I actually posted my results. This was done on a dynojet Dyno (One of the ones that go off your back wheel) in Hamilton. What sort where yours done on?

[HDTboy]

Dynojet dyno at Henderson Motorcycles.
Would be interesting to see how much power my bike makes on the dyno you used in Hamilton

[speedpro]

I wonder if the correction factors were included in the calculations.

My sheets have "CF: SAE Smoothing: 5" written on them

[NordieBoy]

My sheets have "CF: SAE Smoothing: 5" written on them

All that does is smooths out the othewise sawtoothed curves.

[FROSTY]

I can't see much point in using a dyno just to get a number on a bit of paper.
For me dyno runs are about optimising fueling throughout the rev range
Best fueling means a smooth power curve. To me a smooth curve makes for a more ridable bike that in my opinion is more pleasant to ride than something that has a boom n bust power curve

[Fox Rider]

My VFR750...

[speedpro]

My sheets have "CF: SAE Smoothing: 5" written on them

No correction factors - good for big numbers.

that video of the 'busa has a few things that are a bit dodgy or just plain bad practice

[doc]

I'm pretty ignorant when it comes to all this stuff. But I've got the spare income to spend on this stuff. What I want to know from this stuff is honest results. Like yeah a pamphlet says my bike does 100 whatever thingys. So put up on a machine and if you have to tell them stuff to get results I think I'm geting ripped here. If I put my toy on a dyno I just want them to tell me what it was, then tell me what I've done and show the difference. Dynojet are starting to look like the MacDonalds of Dyno's. They will give you what you want, you pay the money and you get a result you are happy with.

[HDTboy]

Dynamometers are a tuning tool. As has been said earlier, the numbers are not important. What is more important is the shape of the torque and power curves.

We tell the dyno operators what has been done to the bike in order to make the tuning process easier for them, and cheaper for the customer.

The bigger and flatter the torque curve, the better. Any dips in the torque curve show up exponentially in the power curve, and feel like flat spots when riding the bike. With a big flat torque curve, the bike will feel like it has plenty of power on tap at any point in the rev range.

The numbers are useful for comparison when all of the conditions of the dyno runs are exactly the same

As an aside, the higher in the rev range that an engine develops peak torque the better for when you are giving it shit.

Commuting or cruising it's nicer to have the torque lower down.

Save me searching for bad shit, what they saying?

Given the manufacturer claims 150 at the crank I would have expected to loose 15 to the wheel which would be 135. Allowing for the usual loss that occurs between the factory and the customer 128 for the base run seems within the realms of possibility.
It certainly has gained in power but more importantly the snatch in the throttle has now gone.

[The Stranger]

nice... :D i've just sent mine to your hotmail bro..post it up ;)

What is the lower trace? Air/fuel

[The Stranger]

Well as we know, dyno tuning a bike is a waste.
But hey I'm happy wasting my time and money anyway.
Even happier with the 10hp gain.

Added a DNA air filter and Yoshimura TRC slip on. The slip on comes with a mid pipe that does away with the EXUP valve, hence a little loss in power below 4,000 rpm.

What is it with dyno results? All that my bike pulls harder than your bike is a load of wank factor. What's wrong with getting your bikes out on a track and see who has the biggest balls and the best skills?

but if it pulls harder it cums faster... or something like that... :doh:
