Brabham BT23:The FIA introduced new rules for Formula 2 for 1967. Cosworth developed the 1.6 litre 4 cylinder FVA engine (four valve assembly) for this formula and Brabham released a new model the BT 23. Brabham and Hulme drove chassis 1 and 2 for the Brabham works team, and Roy Winkelmann Racing (a semi works team) entered chassis 4 and 5 for Alan Rees and Jochen Rindt respectively.
Rindt had a phenomenal record in his car in 1967. Out of 15 races he won 9 and finished second four times. In the FIA European F2 Championship he won 6 out of 10 races, but was not awarded the championship as he was a seeded driver. That honour went to Jackie Ickx. This Rindt association is very relevant to the recent auction of the car (see below).
For 1968 Hulme had signed with the McLaren Team. This meant Hulme was forced to find his own car for the 1968 Tasman Series, unlike previous years when Brabham had provided. A Repco V8 was not available so he turned to FVA engine cars. He thought that Rindt’s BT23-5 was much better than his BT23-2, so he made arrangements to bring that. Never mind greater ability.
Hulme crashed BT23-5 in the first race of 1968 series, the NZ GP, on lap 56 of the 58 lap race. He collided with local Laurence Brownlie, with both cars turning over and “disintegrating”.
Hulme was forced to arrange to bring out BT23-2 from Europe for five of the remaining races. He didn’t manage any wins, his best being third at Wigram.
After the Tasman series BT23-2 went back to Walter Habeeggar of Switzerland for 1968 season, then in 1969 to Scuderia Picchio Rosso for Enzo Corti. In 1970 to Vittorio Brambilla, and last seen 1970. A chassis being restored in 2009 may be this one.
After Hulme’s crash in the 1968 NZ GP, Rorstan acquired BT23-5 (less engine) and sent the chassis to Bob Brittan (Rennmax) in Sydney to fix. Rorstan retained the suspension. However Bob hated fixing things, so made a jig after straightening the Brabham, then sent back to NZ a brand new BT23 style car containing all the usable BT23-5 bits, and with space for fitting a Climax 2.5L. This jig was to be used for the creation of 11 cars including the Mildren and Rennmax BN3 cars. The old chassis (BT23-5) went to the roof of Britton’s shed.
Rorstan called this new car the Rorstan 1 Climax, chassis # RMR1. It had distinctive very upswept and long exhaust pipes for a Climax engine car. Stanton never pretended the car was a Brabham.
For 1969 Rorstan initially signed Jim Palmer to drive the Rorstan on the promise it would have a Repco V8. The car was entered for the 1969 NZ GP but when the Repco V8 did not eventuate then Palmer walked, as he knew the Climax would be completely uncompetitive.
Rorstan then recruited Dennis Marwood to replace Bolton for the 1969 series. This was probably at the instigation of Ian Rorison, who was a close friend of Marwood. Marwood’s single searer experience seems to be only from running an almost historic Cooper T66 Climax 2.5L in the 65, 66 and 67 Tasman Series. He had little success with Rorstan. At NZ GP he retired after only 3 laps in the Brabham BT??. Switching to the Rorstan Climax, he then retired from the Levin and Wigram rounds.
Marwood had had enough. He realised the Climax was no match for the new FVA engined cars. For 1970 he switched to an Eisert Chev F5000 owned by Ian Rorison.
For 1970 Rorstan recruited local Bryan Faloon to drive the Rorstan Climax. Faloon had gained experience driving an ex Stillwell Brabham BT4 Climax 2.5L chassis IC-3-62 in the 1968 and 1969 NZ Tasman races.
1970 was another unsuccessful Tasman Series for Rorstan. In the 4 NZ rounds Faloon got 7th at Wigram and 10th at Teretonga, and retired in the other two races.
For 1971 Rorstan finally realised the Climax 2.5 was outdated so a rare Porsche 2 litre flat 8 four cam engine was installed. Chassis number was changed to M1A from Mk 1. It is not known if this meant a new chassis or simply alterations to existing one to fit the much wider Porsche. The engine has been described as variously a 907, 908 and a 771. I will leave that to Porsche experts.
The change to the Porsche engine had even worse results in 1971 Tasman. Faloon was entered for Leven but did not arrive. For Pukekohe and Wigram he did not start.
For 1972, following the breakup of the Rorstan partnership, the car was called the Stanton 1 Porsche.
The Rorstan Porsche was unfortunately destroyed on lap 52 of the 58 lap 1972 NZ GP.
To quote from Bruce Sergent’s report:
“Four laps later Faloon, well out of the running, and Lawrence, still pursuing McCormack, touched at the kink in the back straight to spark off a debris-strewn, dust-enveloped tragedy. Coming up the back straight on lap 52 Lawrence was slipstreaming McCormack while Faloon, seeing the red Elfin bearing down on him, pulled to the left at the kink to let him through. At the same split second Lawrence pulled out of the slipstream to pass McCormack and ran into the back of the Stanton-Porsche at 155 mph. The Stanton was launched headlong into an earth safety barrier, taking to the air before crashing down onto its wheels again. The Lola was cart wheeled down the track, totally disintegrating on the way.
"The Stanton looked relatively intact while the Lola was totally wrecked. The head injuries Faloon sustained in the impact proved fatal. He was only 29. Lawrence suffered broken legs, wrists and concussion.”
The whole Stanton car with its rare engine still attached found its way to Melbourne for then Australian Porsche Distributor Alan Hamilton, who had acquired the car for the engine and gearbox for a restoration. He sold the rest to Melbourne’s Denis Lupton to salvage the genuine Brabham parts (which he on sold to Goodare see below). Where the Rorstan chassis went next is unknown, bur presumed to tip. It may have been made into a sports car, as there was a Rorstan Climax sports.
Meanwhile back at Bob Britton’s shed:
Bob was commissioned by a client to rebuild the original frame as a Formula Ford, using Rennmax uprights etc, but the client never took delivery. The car was then sold to Graham Hepburn of Talbingo N.S.W. and then ended up with Denis Lupton of Melbourne circa 1981.
So now Lupton had the original Brabham chassis, and the original Brabham bits from the Rorstan car. The complete collection of BT23-5 remains, including the rolling chassis, was then sold to George Goodare of Sydney in December 1983. After a major rebuild the car was campaigned by Goodare for many years complete with correct FVA/FT200 etc, and having recast new uprights etc. The car was last raced by Goodare in about 1990.
It was sold in 2008 to Jean-Marie Muller of France, and damaged in an accident and fire at Reims, France, in 2010. Fully restored and next seen September 2013 on display at Heeresgeschichtlicen Museum in Zeltweg Austria, see following, looks to be in very good condition.
http://www.salzburg.com/nachrichten/...elpiste-74531/BT 23 -5 was put up for auction on 26 June 2015. See following for details.
http://www.classicandperformancecar....f2-car-offeredThey seem to be capitalising very much on it being used by Jochen Rindt originally.
There were very step sale estimates of 360K - 500K Euros.
I like the description that “it’s not in great condition”. It looks pretty good to me.
These are the auction results, although for some reason this Brabham is not shown, yet it was until very recently.
https://auctionata.com/s/325/classic-cars#objectsIt ONLY made 235K Euro, about 350K AUD. I reckon that is still pretty good.
I must acknowledge information gained from forums and websites from Allen Brown, Andrew Fellowes, Bryan Miller and Bruce Sergent, and from Racing Car News.
And so ends this lesson.....
