"Tow car", I'd say in these circumstances...

Usually their "support vehicle" when using their normal transporter.

My thoughts too,, though maybe for Amaroo it would be ideal.

Gricey was based at Amaroo.

Got a question about the exhausts on the rotary engines. I remember seeing a tip on a number of rx2/3/4 cars that quiet ended the noise down a fair bit. I don't remember what they were called, but it looked like a gold coloured tip with a number of fins or valves that could be added too depending on how noisy the cars were. Super trap is a name that rings a bell, but does anyone know for sure what they were called or what they looked like?

They were made by Supertrapp, I know a few people that used them on road cars with ported engines, waste of time. Too few discs and they were sort of quiet but killed power, add enough discs (less restriction) not to kill power and they were just as noisy, everyone I know went back to simple off the shelf "as big as you could fit under the back" truck style mufflers.

I know someone looking for good pictures of the Lee/Gates RX-3 as raced at Bathurst in 1979, particularly side shot s clearly showing any signage, would anyone have any they could share? Autopiocs have three but don't show enough side detail.

Darren, as you are aware we have the Lee/Gates car up here.  Autopics have quite a lot more than 3 photos of it; if you search their full Bathurst collection there are from memory around 20 that we have bought from David on the car.  Hopefully not someone trying to recreate it.

Hey John, they are trying to create a near as possible look-a-like for R Factor which is a racing video game, and have suggested they try Autopics too as I know their collection is extensive, much greater than just what's shown online. http://img.prntscr.c...com/KACxd91.png

 

With replica's, not much anyone can do if someone wants to build one, it's not illegal and doesn't devalue the real thing, and without a log book and some serious proof you'd never get one through as a genuine Group C car, it's hard enough getting the real things through if anything is suss!

 

The problem is these RX-3's are very popular, genuine Grp C one's are very limited, and people either hoard them with no realistic chance of ever finishing/racing them so they never see the light of day again, or they want plain crazy money for them even in rough shape.

and the sad part about Autopics (terrific website that it is) is the collection still to be catalogued and made available!

Traps were used extensively in speedway on Sprinters, Midgets and sedans. 20 years ago they were the best. Seemingly surpassed now.

Mazdas have always had a HUGE problem with exhaust temperatures and used to have the things near white hot,, where no muffler works properly. The rotary midgets of the time,, on methanol, used to have the mufflers glowing and on occasion even blowing molten bits out the exhaust. Road race cars were no better. Night races would clearly show red hot exhausts, that in 6 lap races.

This is one of the many problems associated with rotarys and appears still to be.

Darren, not saying that people shouldn't make replicas, some of them are better than the originals!  I have no problem with people painting cars to look like whatever they want, and its great to replicate cars that are missing.  Just worried when people ask questions like that; have already had the situation where a person replicated the previous 'form' of one of my Group C cars thinking that the car didn't exist anymore, and not realising that the car had been updated and kept racing as the next 'model' on and with a different owner; the replica owner claimed to have the original, not with CAMS but just in public.  Makes the C of D process harder.

Totally agree with you, "claiming" a replica as the real thing is dishonest, immoral, and creates a raft of issues especially if the real thing exists.
