Wellington dynamometers

[Hitcher]

Who in Wellington operates motorbike dynamometers, how good are they, and what do they charge?

I've seen one at Motomart. Is that it?

We've got one, Hitcher.

It's a little different to the others in that it's not just a big roller that you wheel the bike onto. Ours has the rear wheel of the bike removed with the chain driving the Dyno, which is essentially a huge pump.

We can simulate real road conditions and vary the loads on the bike. It means we can more accurately determine tuning at different throttle positions and loads.

It also reads differently to other dynos but is more consistant due to zero wheel slippage.

You're more than welcome to come in andf check it out and have a chat to the opperator.

We can plot the power in as small as 50rpm incriments although 500rpm is the best.

I've seen an R1, wailing its head off in 3rd gear and we just increased the load untill the dyno stalled the bike. Try that on a Dynojet.

...it's nice to see someone finally call it a Dynamometer rather than a Dy-no-meter.

I WONderd what that was ...

Snot gunna work on me guzzi though is it.....

The one at Motomart is one of the best in NZ!
Its an "Eddy-Current Rolling road type Dyno" It measures hp at the rear wheel, not the crankshaft. This is a more true representation of actual hp output, so you have something to really boast about to your mates!
Only $95 for a run..
including....
-Air/fuel ratio
-max speed
-H/P
-Torque outputs
All printed on an easy to read graph.
Give them a call.. 04 5895106 or 0800 DUCATI

Or come and see us.

is that a shameless plug for your workplace????

:

That right? How much tourque will does it require to stall a 999 at 5000rpm, 3rd gear 75% throttle?

Sorry....

If you're prepared to pay, we'll make an adaptor to suit.

[Sparky Bills]

Not at all. It was more of a threat! Come in here or I cant tell you what might happen.
White Trash'.. What do you mean? I cant let out any trade secrets. You know how it goes.
Did you want to talk to Craig or Dave instead?

Sorry....

Why the disparity of readings between the MM and WMCC dyno's ?

Jimbo's was putting out 125hp on the MM, wasn't it about 190hp at WMCC ?

I guess the main point in dynoing is to see if you have improved HP by any adjustments, but an accurate HP figure is still important.

How much for a dyno tune? eg fix my 4 friggin carbs for max hp?

OK. But if Jimbos bike went, (heh heh) and he put it on MMs Dyno again, would it read the same again? I doubt it.

Consistancy is a big factor.

Ask Dynojet how many 15,000 dollar rolling roads they've sold to Nascar teams, then ring International Dynamometers in Petone and see where theirs end up.

A rolling road Dyno, takes a large, heavy drum. Then calculates the top speed its spun to over what time frame to work out the HP. Very crude.

Anyway, it matters not what I think as it's obvious a Dynojet is great value for money.

A Dynapak is just a better tuning tool. But then it'd want to be for over $100K
