Throughout Joey’s long involvement with the TT as a privateer and a ‘Works’ Honda rider he always regarded this first win at the 1977 Schweppes Jubilee TT on the Rea Transport 700cc Seeley as the greatest of his career. He is regarded by many TT followers as the greatest exponent of pure road racing ever with a record of 26 wins, 12 more than the late, great Mike Hailwood.
This bike was the machine on which Pat Mahoney crashed at Brands Hatch in 1976, ending his racing career. Jim and Merbyn 'Curly' Scott fitted the Yamaha engine into the Seeley frame. Tom Herron brought a set of Morris Mag wheels from Daytona which replaced the original wire ones. Joey wanted the power from the superior TZ750 but was wary of its reputation for bad handling. A Seely frame originally intended for a Suzuki was utilised along with lengthened swing arm and repositioned shock to give more travel suitable for the road course.
In the race he built up a 50 second lead by the last lap so he had time to stop in Ramsey’s Parliament Square to examine his rear tyre which was losing traction, 13 miles later he recorded his first win with an average speed of 108.86mph with George Fogarty in second and Steve Tonkin in third in the 57 strong field.
Racing on the Isle of man commenced in 1907, the first TT was won with an average lap speed of 38mph., by comparison the 2013 lap record is held by John McGuiness at 131mph. The event has come under continual scrutiny due to safety concerns due to increasing speed and number of fatalities. In 1976 the FIM held up its threat to remove the race from the Grand Prix calendar unless changes were made. Rather than slow the bikes down and introduce safety features to the track the TT Races became part of the TT Formula 1 Championship.

1st - 1991 Northwest 200 250/350cc;
1st - 1991 Temple 100;
Ridden by Robert Dunlop (25 November 1960 – 15 May 2008), a five time IOM TT winner and the first person to be elected into the "Irish Motorcycle Hall of Fame". The younger brother of fellow road racer, the late Joey Dunlop, and like Joey he died after a crash while racing.
Subsequent riders to Robert were;
Gary Stephenson – Newtownards
John Horner – Coleraine
Nigel Watt – Coleraine
Mal McKeown – Portadown
David Mateer - Lisborne
This bike is presented as it was last raced, note the upside down handlebars as the last rider had a broken collarbone and this setup somewhat eased the pain.

Winner 1969 British Touring Car Championship.
In 1969 Alec Poole won the British Saloon car championship with this 8 port fuel injected 970S prepared by Equipe Arden run by Jim Whitehouse.
The Drinkrow brothers of Beachlands acquired the car and that is where it is today. Lynn Rodgers has built a 999cc engine and Peter Levet has built a 4 speed box. Alan Drinkrow has 2 of the 5 speed boxes and has rebuilt them but Levet talked him out of using them (at least in the early stages). Levet went to Arden Engineering to search for parts for the restoration and spoke to Jim Whitehouse on the day 21/3/1981 when Mike Hailwood was so tragically killed just a few miles from Jim's workshop, in fact passing the site of the accident less than an hour before it happened. Levet recovered a lot of TJ injection gear in England and Alan has probably got that together by now. Levet hasn’t seen the car for sometime, but it is probably back in the 1969 colour by now. Levet also recovered 4 of the original Cooper 12" magnesium wheels (as opposed to the Minilites) to go with the re-drilled set that Alan recovered from Jim Maud. When Levet was speaking to John Cooper, he thought that they only cast 7 sets of them so 8 of the original 28 exist in Beachlands!

The "Equipe Arden" car was originally a genuine Austin Cooper 970S and was made into a racer by Jim Whitehouse of Arden Engineering whose business was in Tamworth-in-Arden, about 10 miles south of Birmingham.
Mary and Jim Carney
At the end of the British season in November 1969, the car was immediately bought by NZ-based American Jim Carney for his wife Mary Donald Carney to drive in the New Zealand Championship. At the time, Mary Donald Carney was NZ’s top woman driver racing a Mini Cooper. Jim and Mary Carney took delivery of the car at Silverstone circuit where some small changes were made, i.e. twin-circuit braking for NZ regs, and a changed seating position for Mary.
Mary Carney straps on the helmet for the Silverstone test.
Basically the car was a 1967 body shell with up-rated hydrolastic suspension. Dunlop 3.75/800 x 12 tyres were used on 12 x 6 inch Minilite wheels. The 970cc engine was overbored to 999cc to keep under the 1000cc class restriction. At 8,000rpm the engine developed 105bhp and extrapolating to peak at around 9,500rpm on about 115bhp. The car was a handful with the very peaky ultra short stroke engine (special short stroke Gordon Allen crankshaft with way oversize magnesium pistons in offset bores) and the diabolically difficult to handle Jack Knight 5 speed gearbox. Mary Carney won a national championship race but the engine was unreliable, mainly due to over-revving caused by the vagaries of the gear change. It was very easy to go from 4th to 1st instead of 3rd with the inevitable result to valves and pistons! The aluminium 8 port crossflow head was Whitehouse's creation hence the source of the name -: Arden head. Mark 1 Tecalamit-Jackson (TJ) fuel injection was fitted and this was very temperamental compared to the mark 2 version fitted to other Minis such as Rex Hart's 1275 Cooper. NZ’er Peter Levet rebuilt the engine and gearbox one last time for Jim Carney and tested it at Pukekohe. He lapped right on the lap record with puddles still on the circuit prompting Carney to offer him the car for the rest of the season and after Carney left, Levet went out on a dry circuit only to hook the previously mentioned 1st gear instead of 3rd going into Castrol with the tragic result of a piston getting spat out of one of the intake trumpets. That was once too many for Carney and he promptly sold the car as-is to another NZ driver Barry Phillips.
Barry had good success in the car but now with conventional-stroke engine and various lockouts on the gear change but never completely curing the erratic change. The other gear change problem was being able to go from 1st to 4th which explains why the car would get off the line but apparently bog down on the first up change. Barry raced the car in the Team Rothmans livery.
AUBURN 115 SPEEDSTER
MAKE/MODEL: Auburn 115 Speedster
MAKER: Auburn Automobile Company
ENGINE TYPE: Lycoming Straight 8 Side Valve
CLASS: Boattail Roadster
This 1928 Auburn 115 Speedster is a very rare specimen as only 3 of these cars were ever made as a right hand drive. This particular beauty spent most of her life stored in a shed in Australia. Allan and Bruce Drinkrow purchased the car in the 1980's. In 1992 after a full restoration, Allan and Bruce took the car to America to participate in the Great Race where they travelled accross the States from Charleston to Cost Mesa winning their class. Bruce drove and Allan navigated. They were the first international team home and were named best car in the show.
Q: What is the Great Race?
A: The Great Race is an antique, vintage, and collector car competitive controlled-speed endurance road rally on public highways. It is not a test of top speed. It is a test of a driver/navigator team’s ability to follow precise course instructions and the car’s (and team’s) ability to endure on a cross-country trip. The course instructions require the competing teams to drive at or below the posted speed limits at all times.
Driven by Tony Longhurst and Alan Jones in the 1990 Australian Touring Car Series and Tooheys 1000
During 1990 it was generally acknowledged that the Benson & Hedges Sierra's were the most powerful in the world with a reported 590 bhp (440 kW; 598 PS).
Tony Longhurst and Alan Jones finished 6th and 9th respectively in the Australian Touring Car Championship (ATCC) with Longhurst's 2nd placing in Round 4 at Winton being the best result.
At Bathurst Longhurst set the pace in qualifying for the Tooheys 1000 with a 2:13.84, almost half a second faster than the 2nd fastest car. Both Benson & Hedges Sierra's failed to finish suffering engine failure on laps 53 and 65 respectively.
