Vintage/historic racing qn: 1963 DKW-Porsche TM Special

I was wondering how this car is able to be vintage raced in the USA, given that the current motor was not of the type used in period. Under Australian rules, this car would have to run a 4 cam (or half of one) to get a historic logbook to race against other 1963 period cars (or a 911 motor to run against cars of the later period when that motor was fitted).

The USA rules are obviously different. Can anyone shed any light?

Beautiful restoration but are you sure it was raced in its current configuration?

Frank,

That was why I asked the question.

In Australia, that car would not be allowed to race (unless you could prove it ran back in the day in its current spec).

So how does it get allowed in the USA?

There have been a couple of stories published on this car. It's interesting, but if it were more significant it wouldn't languish at FJ for the past year.

Naturally, building a cobbled up 2-cylinder 547 as the original builder did is now cost prohibitive... Ryan, are you saying it wouldn't be eligible
in Australia without that engine? Do all vintage/historic racecars in Australia really have their original engine?

According to the seller, at different times in it's race history it's run a 2 cyl 800cc four-cam, a pushrod 1600 and a 911 motor.
Most historic/vintage groups here and in Europe would welcome it in any of those configurations because all are SCCA recorded, logbook existing and original engine(s) or not.

Can you image a 911 motor?
THAT car with any more than 200 hp would be scaaary.
Needs brakes, tires, and much lower CG.

[Bullethead]

Yeah... and it was autocrossed with a 911 mill. I'd like to see the time sheets.

The thing's too heavy to be competitive with a 1600, it's most interesting feature was that split 4-cam it once had.
If it still had that powerplant it would have no trouble selling.

I think the issue is that the info from the seller only mentions a half Carrera, a full Carrera, and a 911 motor. No pushrod 4.

From the Fantasy Junction ad copy:

Thews then bought a pair of brand-new 1600cc Porsche Type 692 four-cam Carrera engines in Texas.

My bad... you're absolutely right. I thought for sure I'd read a piece about this car that mentioned an SC motor in it's life but couldn't find referrence anywhere.
A Typ 692 will about triple the cost of getting this historically correct, so $55K is just the start... can you imagine doing the twin version too?

Hi Russ,

You must run the original type motor here.

Back to the original question - is this car eleigble for historic racing in the USA?

[Frank Beck]

Absolutely.
SVRA and HSR would find a group you could run with.

The tea and crumpet organizations would probably shun it though.
