Job done.[smilebigeye]

Nothing wrong with a good sound system and a recording of a Chrysler Hemi powered AA Fuel dragster starting and staging. A 540 cubic inch hemi running about 60 lb of boost on nitromethane blend and open pipes would get anyone's attention.

They were also used by the London Metropolitan Police, and acquired the nickname Noddy bikes.

Old motor cycle racer and proprietor of Baxter's motorcycles in Fortitude Valley once told me that to his undying shame he got a speeding fine on one. A bit like getting a speeding fine on a diesel Series LR.

My comment at the time "Downhill, was it, Jack?" His reply "Not you too. The world is full of smart arses." He reckoned it was like being caught out in public with a woman not your wife. Everyone he knew happened to walk or drive past as he was being booked.

A friend had an LE Velo for a commuter bike. He reckoned it not only ran on the proverbial oily rag, you didn't have to re-oil the rag very often.

What? Never been to the drags (not the street drags, but real, high horsepower)? Really? You must, then you’ll understand. Until you’ve been, you don’t know what loud is or how it feels ​when they launch. Don’t go and YouTube it, that doesn’t cut it - get down to your local track next time a meet is on - even if you have to drive all day to get there. 👍

WOT! Drive all day just to hear a loud noise? And back again?


Yeah roight. I know 'er indoors says I look stoopid but I assure you it's only the grey melange short trousers & the black horn rim Bi- focals that give that impression. :Thump::Rolling:

Yep! You want to hear something really sad? I used to drive 4 hours each way to Calder Park to watch the Top Fuellers when they were in town. I now live 10 minutes away from there and they don’t come any more. 😥

The top teams are now finding 11,000 horsepower and doing 3.6 second quarters. You can feel the noise as you say. Google AA fuel dragsters and look at the engines being built and rebuilt. These teams are THE experts at getting horsepower. Look at the quality internals in those engines.

That’s just insane. They were searching for 6,000HP and sub 5 seconds back when I younger.

I was an ANDRA steward at Willowbank the night of the first side-by-side 4 second pass.
It's a true sight and sound spectacular.
Some of the best times were when I had to escort corporate types down to the start line. Seeing their faces when two Top Fuel dragsters launched about ten feet away was priceless!

If they put that on an electric bus no-one would ever fail to know the bus was coming.

Stab your eyes to not hear it?
Why not just stab your eardrums and not look at it?
