Patrick's 1973 Martini RSR recreation Project

[e72phil]

Patrick, did you look at any of the 10K tachos offered in last weeks auction ? Were any suitable ?

[patrick911]

Hi Phil, yes, there was a 10k tacho for sale (or maybe even two) but it was the 'standard' 10k type (110mm can, 30,000 imp) and it wouldn't surprise me if it was a conversion from a standard 8k tacho (24k pulse, just with a different dial and re-calibrated). and that last option (conversion) was what I was planning to do myself, so if there's anyone that needs a 8k tacho with a silver dot in decent condition.... hit me up.

Looks pretty good, even if I say so myself

Picture of the dash of my replica. I'll wait with putting the black square tape over the silver dots until later, as well as the orange line indicating max revs on the tacho, and we also still need to drill holes for the red idiot light and the twin plug pulls.
I even bought the exact year Dymo label maker on Ebay a couple of years ago for the labels on the (90 degree turned) first gauge.
they will have to come off again, if they don't do that spontaneously, as the glue after that much years lost its adhesion. But you get the idea.
(and yes, the second gauge is not quite level....)

With the idiot light and the two CDI switches installed, all gauges connected, focus shifted to the front suspension.
It was a bit of a puzzle, as none of the RSR specifics (floating front discs for example) are really described anywhere, but we got it in, only to find that the spindle height on my shocks was too much; the a-arm hits the underside of the 9" wide 15" wheel. The RS had raised spindles to have the car sit lower, but it was 19mm higher than the standard, whereas these where +26 and obviously too much.
So that's something to fix but other than that pretty happy with the parts and the process.
It looks fantastic, it's just a bit of a waste really that you won't see it once the wheels are on.

that is a work of Art

Thanks Marcus,

I also posted the question on the early911s registry, but if anyone has any details on [or pictures of] 1973 RSR rear suspension (like wheel hub, drive shaft & brake-disc & hat arrangement), I would be very grateful. My collection of pictures, pbase.com/slidevalve911rsr, Konradsheim RSR book, etc. do not seem to have any detail on this so hoping someone here may have something useful.
thanks heaps,

Patrick

If no one has Patrick you can do as you like as they can't refute what you have done.

Hugh would be your best chance here.

Jim Torres in the US responded and indicates it is the same standard rear wheel-hub, just with the edge slightly trimmed to make it fit into the brake hat.
So let's see if that works... but you're right Clyde, a lot of this is trial and especially error

[patrick911]

See Clyde, on its wheels, just in Dakar mode at the moment until we sort out the ride height

Not that I am keeping track but 9.5 years comes up tomorrow

Almost 10 years now

With quite a few people asking about it yesterday at the Gippsland drive, i realised my last update here has been 5 months ago.
No, the car still hasn't finished, but we (me, Jason & Spencer) have made quite a bit of progress.

First, I managed to get the exact replica of the front central Behr oil cooler that was used in the 2.8RSR (3.RS had a larger one) and in the 914/6.
Beautifully made in the UK thanks to the efforts of Darren (who has quite a few build topics on early911sregistry and DDK forum) the trouble has been how to connect it.
After studying a lot of pictures, we figured the protective raster was fitted to the oil cooler, but making it look nice means it is a bit more forward, leaving very little space for the connecting 2 oil lines due to the curves in the RS bumper. Anyway, we'll figure it out, but it's things like these that keep Jason busy and prevent us making a lot of progress.

The ride height is fixed; turns out that Elephant racing mounted the coilovers on the wrong shocks when they shipped them and I never checked....
Not great - but at least it makes more sense now and it looks as if the height is at least in the ballpark.

I got the larger RSR oil tank, and Jason made it fit, (the chassis is a 1976 and the 2.8RSR oil tank has filter and filler positions swapped so yes, none of these things are standard), i fitted the emergency brakes on the RSR calipers, Jason prepped the pain for clear coat, and I refurbished the emergency handbrake assembly from that of a g-series back to that correct for longhood cars.

Then on the engine side, Spence (Harrison's RRR) has gotten the magnesium case back, boat-tailed and treated. we got the time-certs done and did some dry fitting with the amber engine shroud and smaller fan housing, he now needs to make room to fit the larger GT-3 oil scavenge pump I ordered.

We also got the heads ready for twin plug and with larger in- and outlet ports, and aiming for spot on 10.3:1 compression. we already had the 2.8 Mahle pistons, but now Spencer has also got the cylinders alusil'd as per the original. Small bits and pieces (valves, filters, gaskets, etc.) on their way so the engine can soon be built up.

I'm planning to take a full week off work to make some traction on the car, because 10 years is long enough.

Few pictures:

Keep at it Patrick

Wonderful Patrick you are nearer the end than the beginning …. Not far now
