100th Anniversary of Indy proxy! Moving forward!

Allan , although these have spokes rather than disc inserts I think you may find the sizes right.
They are at Pendles under PCS spares.

Bob, first car bottom row what is it?

[btaylor]

Mark, That is a Kurtis 500.

thanks Bob, I grabbed that one from the box at Harrys, and was getting ready for some research and building.

No Problem! specifically, that is the "Sumar special" from 1957. STP car.
If that helps.

Allan;

What is the outside tire diameter we are looking for on those wheels for the Marmon? I have a pair of CBD 16.5 x 7 insert wheels with Luf's urethane tires on them that come in just under 2.5mm. Probably still too short. The real tires were probably almost 3 feet tall. I could find only one scale drawing of it that gives a good side view, but no measurement on the tie diameter. Do we have anyone on here close enough to visit the Museum at Indy with a tape measure in their pocket?

It is looking like there is lots of interest in this thing, and it should be a go, eh?

I have the two different turbo bodies ordered that I hope will make it north soon. Chassis should be no problem, but I need to know about motors. Is it like Indy back then, open rule book?

I'll be watching for a rules and registration page.

Bob: I must have too many proxies swirling around in my head. I even posted to that thread, but couldn't find it, or forgot it was there.

I have one question, however. Pre 1970, the rules were quite open for Indy cars. Drivers could race anything from Offies and Novis, right through DOHC Ford V-8s, Cummins Diesel to Pratt and Whitney turbines. Hence my question, why are we limiting the motors to a slim can @ 18K? There is a very limited selection of these, by the way, as BWA and M/Ts are under 15K and Scaley, Fly, Scaleauto and MRRC are all over 18K. I realize the aim is to prepare equal cars, but this was not the practice at Indy in the pre 70s.

This is your proxy and of course I will still enter under the rules, but I think we should open up the motor/gear rules and let the chips fall where they may. I have a 27K long can with heaps of torque whose performance would resemble a turbine in my Lotus turbo. An open motor rule allows builders to fit the motor to the car just like the old days, eh? Of course, if you over power a light car, you lose, so it is always a balancing act. A big part of the challenge is getting the best balance between power and handling.

What do others think?

Thanks,

Keith

Vintage:

I also searched for ever to find the Hurst shifter and might have even carved one to cast, but the best I came up with was someone makes a die cast in either 1/43 or 1/18 scale, I forget which. Someone with the knowledge could do the scan/resize/3D print routine.

There are lots of good pictures of the car, so even the basic dimensions would allow a model to be built that would be close enough to seem scale. It is strange that there are no drawings of it, or posted dimensions. Some slotter near Indy need to go to the museum with a measuring tape and note pad in their pocket, eh?

I'll bet there would be a market for a resin kit for it. I would build one just for the novelty of it.

Cheers,

Keith

I very kind Indy Roadster fan very kindly provided me with a scale drawing of the 1962/63 Kurtis-kraft 500 Hotel Tropicana Novi...so the mold making process begins!

Keith, The Slim can motor was picked due to the Size restrictions of the Scale indy car bodies available. Most of them would not accept anything any larger. I am not hard lining on the gearing, just a starting point to keep the cars running basically the same. A slight variance would not disqualify a car.
