NZ land speed record?

[MyGSXF:Me]

No he didnt... Glen Hayward was faster on the day

Wrong!! Just been talking to Phil.. he confirmed HE got the NZ record & Glen got the World record!


As a side note: Phil is heading over to Bonneville 28th of Aug, to help the new owner of the Flying Kiwi break the current record!! & while he's there, he's having a blat on a 1400 Kawasaki Turbo!!!!

He's also pretty sure what Koba said.. is still current.. ""Around March 2000, John Hepburn of Timaru set a new NZ land speed record of 307.447km in a run in Southland near Edendale on a Hayabusa"

You could always bolt a sidewheel onto a dragbike and go for the sidecar world record........ eh sidecar bob.......

How does the timing work on these records attempts? Is the measured speed normalized against a set of predefined atmospheric conditions?

Hi I think it was Brian Bernard on Suzuki NewZealands Hayabusa , from memory they only got around 314km cant rember the exact year but around six years ago , in the Sth island some where maybe Christchurch

I actually remember seeing it on the news years ago , was on a straight road just out of Ashburton , only remember that as i was born there and bout 4 years ago got a speeding ticket - i think it was on the same stretch of road

The sidecar one was set at Chertsey this side of Ashburton, the Motorcycle one was set near Edendale

Glen was faster on the day at 272kmh, but his is the world record, Phil holds the NZ record, although it'd be an easy one to beat

Thanks for that link!

I couldn't see atmospheric conditions were mentioned.

It seems odd if timing devices with the resolution of at least one fiftieth of a second are required, but no measure of atmosphere is carried out.

As far as I know with the little aviation theory I've been studying, engine performance can change around 10% from day to day. It wouldn't be too hard to convert the speed to ISA conditions just to see how much it would differ, if it would make any practical difference.

The bike is capable of 350km/h

That Herald article is full of shit. There's no way that a 1098R can go 350km/h without serious and substantial modifications.

Who said anything about a 1098R? They are talking about the desmosedici...

The only possible way anything will do 350k is via streamlining, HP is worthless over about 270K.

Hi Just wondering if any knows what the NZ motorcycle land speed record is. When and where, by who and on what bike?

Tell us just how fast you went and where you did it?

[T.W.R]

The sidecar one was set at Chertsey this side of Ashburton.

Glen was faster on the day at 272kmh, but his is the world record, Phil holds the NZ record, although it'd be an easy one to beat

Chertsey Kyle Rd to be exact

And they F@*#ed up too and used the roughest road in the area

Pressure and density heights would make a huge difference.

kiwifruit holds the record for speed in a straight line and speed on one wheel..

check out YOUTUBE.. for real !

Ok, is it just me, or does 307 not sound that fast?

Now, I'm not advocating doing anything illegal, but I worked out the gear ratios and final drive on my humble scoot, and it worked out about 310 (on the limiter in top). The speedo stops at 299, but they lie like politicians anyhow.

I would have thought a hayabusa would've gone faster given my experience with them.

I'm assuming that you can change gear ratios, and run taller back ends, and with the mirrors off...

307 should be achievable...

Anyone willing to give it a go (meaning loan me a Hayabusa for a day?). It'd be interesting to find somewhere and get the permissions to try it out. I'd be willing to give the 1000cc record a nudge...
