Thread: Speedway OOPS

What are the rules /specifications for that class, Andrew? They look like the sort of doggy "Super Modifieds" that descended from "Hot Rods" and "Stock Cars" in the 1960's. What engines are in use? What is the track diameter?

Super Mods got pretty classy for a short time until displaced in popularity by true sprint cars. Current Sprint Cars (and midgets) are pretty high tech and you need to be rich or have a rich sponsor to have a sprinter that is successful in open company.

I have an open cockpit sprint car from the late sixties/early seventies. Restoration is stalled until I make a couple of decisions as to what I am going to do with it, and decide what engine to go into it.

I am torn between restoring it as a sprint car for historic speedway but these do not race, only demonstration runs because of insurance restrictions, or making it into a road racer for the short track autosportsman sprint series. The guy I got it from was halfway through doing the latter option. He kept the iron Chevy (600 hp) for one of his others.

The chassis has been centralised (the offset taken out), wheels down to 10" front and 12" rear and no stagger, and a clutch and Toyota three speed box fitted. I was hoping to find a big Offy whilst in the USA last year and am still fishing for one. I found one, a 255, at Zakira's Garage with an extra crankcase breather where No1 leg got out of bed. This is being repaired and a mate is buying it for a Miller replica. Stewart van Dyne has another, a 270, that needs another block. The brand new repro block busted on the dyno and there is a dispute between Stewart and the maker of the block. This may take a while.

Real motor racing has dirt, lights, methanol, and Offenhausers!!

Hi Brian
Dont know alot about them.
They are modled on old styled Sprint Cars.
They run V8s,up to a Holden 308 V8 which is fairly stock.
No gearbox,just a dog clutch.They do run staggered rear tyres but dont allow racing tyres to keep the racing even/cheap.
Try a google,WA Super Mod Assn is thier club.

Can't find a web site for them. May be my lack of search skills. The speedway sites I could find have virtually no information other than dates and locations.

Have a look at the following link, it should be the specifications for each vehicle class.

At about the 1:30 mark are they racing in the opposite direction ?

Hi Brian I recon you should restor it as a Sprintcar. As for not racing, yes only demonstrations. VERY VERY SPIRITED DEMONSTRATIONS.

Not permitted to break traction. Those who get a bit carried away attract the ire of the flaggies. The three vintage/classic/historic clubs in Brisbane don't have a lot of money to spend on public liability insurance and bureaucracy hence they do not race. They don't do timing either as this could be construed as running a motor contest.

Anyway, given the state that has been reached, it is easier to complete the conversion to road racer. It was used briefly on a short road circuit and I had a few laps in practice. This was a real hoot. A 600 hp methanol chev in a car that weighed about 600 kgs. Wheelspin at will, dirt track power slides on hotmix. People queried it having only a three speed box and the owner replied that he didn't need first, and the other two gears seemed more than adequate. Just stick your boot into the Hilborns and away it goes no matter what the roadspeed or gear selection.

Maybe things are a little more lax in Vic
