Dry Lakes Racers Australia

Guess you'll have to get it machined out of solid then.

Don't you wish you had the resources to build an engine like this?

You can't leave it that.
We need much more detail.
Quad turbo sidecar?

I was watching top gear Australia the other day and they had one of the supercharged walkinshaw clubsports on. The Stig gave it a thrashing and came up with a lap time. Then they took the posser rims off and put small wheels with taller profile tyres on. Went 3 seconds faster (even beat the W427 meg...

2!! now that;s just being greedy.
Doc I'll distract him, you nick off with one.

Doc I'd be careful about your assumptions. When Chris was running his roadster at Bonneville they were have trouble getting over 200 mph with the tall gearing. They actually dropped the diff ratio and have now run the record up to 229 mph. The problem they were facing was that the step between gears...

If you're really really nice to me I'll tell you why we want one... It's obvious... the tank is going 4 wheel drive! Have you considered asking over at ozerodders or one of the old holden websites? Great talking point though. Ford (8" & 9") have better bearings, GM (10 & 12 bolt) ...

Big Gaz has gone for a powerplant upgrade. There's some of uncle sam's iron under that blower. I think the starter motor would have more grunt than a jag V12. Check out the build diary. I'm not knocking your choice of gearbox but people tend to steer clear of overdrive gearboxes for slat cars. Someo...

I was researching Kamm back cars and found this. http://tonyfoale.com/Articles/Aerodynamics/Aero1.gif To me the rear end of the JCB (and a few other very fast cars) follows this to a degree. The second example shows why it's so much harder to go fast with a production car based racer.

So does that mean you're back building again?
Belly pan? Top chop?

Bob told me at Don's last meeting that my car has to have the 25% engine setback to qualify for Competition Coupe, which is clearly impossible and not what the rules as written say but if that's the way they're interpreted I'm out before I start. According to the rules on the DLRA website; Competit...

I think flatfire was an entirely different car.


Makes sense to be tall and narrow for stabilty.
Hard to be 100% sure whether its aero, horsepower or good luck that makes any particular car fast.

My vote would be for a flat bottom.
Cars like poteet & main speed demon look like a good design.



BUT according to the first post a half teardrop has a higher drag co-efficient.
To the bat cave, I mean wind tunnel.

In regards to going up and down a class. The Buick V6 came out has a 3 litre, so that would take you to F class. If you get the 4.1 litre block you can bore and stoke to 274ci. So that it'd get you up to D class. I reckon you're onto a good thing. If you did wanna go V8 I'd look at how the Formula S...

Jess Doc I don't think you're trying hard enough.

Seriously though have you got any pix of your car that show the drivetrain packaging?
