Aeronautical Heritage – Mackson 500 F3

The Mackson 500 F3 came about through a short lived collaboration that started in 1951 between constructor “Mac” McGee and aeronautical engineer Gordon Bedson who’s curriculum vitae included working for Vickers Armstrong on the ultra modern Valiant jet bomber.

The Mackson was built in Guildford Surrey with a tubular frame, independent front wishbone suspension and swing axle rear and fitted with the latest Dunlop alloy wheels.

A Norton double knocker engine was specified, although an example has also been fitted with a JAP engine in the United States, the Norton gearbox transmitted power to the rear wheels through chain drive and the solid rear axle.

The 18 gauge aluminium body is noticeably lower than it’s contemporaries like the Kieft CK52 and Cooper Mk VI.

Designer Gordon tested the original Mackson, but Arthur Gill ran two cars for himself and Alan Scoble while a third car was bought and raced by Peter Braid, with no wins during the 1952 season Gordon Bedson left the team to become a director at Kieft.

No more Mackson’s were built, but they continued to be raced, one being converted into first the Saxon Formula 3 car which was upgraded to Formula Junior spec, Gordon Russell is seen at the wheel of today’s example at Castle Combe.

Ian’s Great Escape – Oulton Park Gold Cup

At the weekend I took a break from attending the Gold Cup on Monday as in recent years and went on the Sunday, my decision was influenced by slightly larger grids for the races and slightly better weather, I was rewarded with a short lie in and a great day’s racing which kicked off when Tim Murray and I visited the press office where we were greeted with a warm welcome and great cup of coffee by friends made over several years on The Nostalgia Forum.

Morgan, Kivlochan, Ginetta, Ward Booth, Lotus, Barter, Ginetta Boland, Gold Cup, Oulton Park,

After a quick visit of the pit area we made our way to Deer Leap for the 10 lap Oni Plc Historic Road Sports race which was led on the opening lap by front row starter Kevin Kivlochan in the #98 Morgan Plus 8 seen above already in second place on lap two. Pole starter Julian Barter driving the #51 Lotus Elan S4 completed the opening lap in 4th but recovered to relieve the races second leader Roger Waite in another Lotus Elan on lap 5, the red #32 Ginetta G4 driven by Patrick Ward Booth finished 3rd ahead of Kevin’s Morgan and the blue #27 Ginetta G4 driven by Dave Boland.

Lightening Envoyette, Peter Moreton, Lotus 22 Andy Hibberd, Gold Cup, Oulton Park,

We moved to the inside of Lodge for the next couple of races. Above Peter Moreton had an electric opening lap in the first of the two Silverline Historic Formula Junior races leading the field from 4th on the grid in his #75 Lightening Envoyette, front row starter Andrew Hibberd in the #179 Lotus 22 completed the opening lap in third and is seen above lining up to relieve Peter of the lead for good at the end of lap 3, John Fyda driving a Brabham BT6 finished second ahead of Peter with less than 6 seconds covering the top three after 20 mins of close racing.

TVR Griffith, Gardner/Cox, Mike Whitaker, Gold Cup, Oulton Park,

Mike Gardiner and Dave Cox qualified their #77 TVR Griffith on pole for the HSCC Guards Trophy supported by Dunlop Tyres GT Race but there was no stopping Mike Whitaker in the similar #46 TVR seen above about to take the lead at the end of the 2nd lap which he would hold onto until pitting on lap 11 handing over the lead to the similarly Ford 289 powered AC Cobra driven by Robert Bremner. After the pit stops had cycled through Mike Whitaker led until the end of the race ahead of the Gardiner / Cox TVR and Robert in the over steering (loose) AC.

Brabham BT21, March 703 Simon Armer, Gold Cup, Oulton Park,

By the end of the 40 min GT race Tim and I had made our way over to the inside of Old Hall from whence we watched the start of the first of two The Cubicle Centre Historic Formula 3 races. Fourth place starter Steve Seaman in his #26 Brabham BT21 nipped through to lead the opening 4 laps of this race from pole man Simon Armer driving the #22 March 703 who is seen above about to pass Steve to claim the lead which he held onto to take the flag a gnats over 17 seconds ahead of Micheal Scott’s Brabham BT28. Steve came home forth behind clear championship leader Leif Bosson driving another Brabham BT28.

Chevron B37, Neil Glover, March 742, Mark Dwyer, Gold Cup, Oulton Park,

One of the highlights of the weekend was seeing Neil Glover driving the one off 5 litre / 302 cui 1976 Chevron, celebrating it’s fiftieth anniversary this year, B37 F5000 car which he qualified second for the first of the weekends Derek Bell Trophy races behind the 2 litre / 122 cui 1974 March 742 Formula 2 car driven by Mark Dwyer. Neil snatched the lead for the opening 3 laps of the race with Mark snapping at his heals in the nimble March who finally grabbed the lead on the third lap and pulled out a nearly six second advantage when a major incident between Denton’s and Cascades required the red flag to be shown on the 8th lap.

Ian Ashley, Derek Bell Trophy, Gold Cup, Oulton Park,

5th place starter 67 year old former Grand Prix driver Ian Ashley driving the #188 Lola T300 Formula 5000 car came down the chute between Denton’s and Cascades for the 8th time in 4th place behind the Clubmans Mallock driven by Mike Charteris when he came across a hapless lapped Brian Cullen driving a 1970 1600 cc Formula 2 spec #18 Crosslé 19F. Just after the Denton’s right hand kink Ian clipped the left rear wheel of the Crosslé with his right front and went flying down the track until his rear end hit the retaining barriers which sent the car into a barrel roll before landing on it’s right side and then came to rest miraculously the right way up. Fortunately Ian was able to release himself from the remains of his Lola unaided and gave spectators a thumbs up to a good dose of applause, neither driver suffered any injury that I know of.

 Jaguar E-type, Micheal Wilkinson, Gold Cup, Oulton Park,

After the dramatic low’s and high’s of the incident the 40 min Jaguar Heritage race passed by in relative tranquility. The third place starting #50 E-type of Michael Wilkinson and John Bussel took over a commanding lead with 6 laps to go, when Martin O’Connel’s pole winning E-type retired 1 lap after his compulsory pit stop, to finish over a minuet and a half clear of Paul Castaldini who was just third placed pairing of Dave Coyne and Robert Gate who made it an all E-type podium as several of the cars struggled to the end with smoking brakes, exhausts and or transmissions.

Lenham P69 Waggitt/Needham, Gold Cup, Oulton Park

Normal service returned with the Guards Trophy supported by Dunlop Tyres Sports Racing cars race. On the opening lap 5th place starter Jon Waggitt was the man on the move with the #33 Lenham P69 seen here followed by the pole sitting and eventual winning #18 Elva Mk 7, driven by Maxim Bartel and Callum Grant, ready to pounce by the front row starting #6 Chevron B6 driven by Nick Thompson and Sean McClurg. Jon kept the lead for all of two laps before the #18 reasserted qualifying form and went on to win the 40 min race by over 8 seconds from the #33 Lenham that Jon shared with Peter Needham that finished a further 5 seconds ahead of the Chevron B8 driven by Charles Allison. In the back ground seventh place starter Marcus Mussa spins his #88 McLaren Elva M1B going into the Hislops chicane.

70's Road Sports, Gold Cup, Oulton Park

The 20 min 70’s Road Sports Bob Trotter Celebration Race may have been shorter than some, but provided the most closely contested victory as second place starter Jim Dean made the running over the first five laps in his little green #72 Lotus Europa, eventual winner, by just .089 of a second, was Charles Barter whose powerful blue #24 Datsun 240Z started 3rd but had to take to the escape road going into Hislops on the opening lap in order to avoid the spinning 5th place starting Lotus Elan driven by Iain Daniels. Jim finished 2nd just under 5 seconds ahead of the light green #1 TVR Tuscan driven by Peter Shaw.

March 703, Simon Armer, Gold Cup, Oulton Park,

The starting grid for the second Cubicle Centre Historic Formula 3 race was exactly the same as the first, unusually the finishing order of the first race played no part in the starting order for the second, once again it was third place starter Steve Seaman in the Brabham BT21 who went into the lead on the opening lap, but this time he held onto it until lap 6 before a determined Simon Armer found away past for the final two laps of the race which he finished just over half a second ahead of Steve and nearly 8 seconds ahead of Michael Scott.

Historic Formula Junior, Gold Cup, Oulton Park,

The grid for the final race of the day, second Silverline Historic Formula Junior race was determined by the finishing order of Junior race one, but pole sitter Andrew Hibberd finished the opening lap in third as the electric Peter Moreton again led with John Fyda between them. Andrew is seen above having just taken the lead from Peter who was demoted to third as John followed Andrew to take second on lap 3. The order remained the same until the end of the race with the top three again finishing less than six seconds apart with plenty of entertaining battles through the field to keep the results uncertain until the very end of a great day’s racing.

Thanks for joining me on this “Ian’s Great Escape” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again tomorrow when I’ll be visiting the Rolex Monterey Motorsports Reunion. Don’t forget to come back now !

Happy Birthday Cheryl – Marcos Mantis GT2

After the successes of the Rover V8 powered Mantula Rover based Marcos LM400, LM500 and LM600 GT cars which won the 1995, 1996 and 2000 British GT Championships Marcos announced the Dunlop sponsored spec Mantis Challenge in 1998 with spec normally aspirated quad cam Ford V8 motors.

Marcos Mantis GT2, Britcar, Castle Combe

In 2002 racers Warren and Charlotte Gilbert (nee Osborn) established Topcats Racing in Westcott, Buckinghamshire which has become a leading contender on the British Endurance GT seen and a leading independent service center for Caterham, Corvette, Lotus, Marcos and Mosler cars offering everything from a full service to an LS7 engine transplant.

Marcos Mantis GT2, Britcar, Castle Combe

Today’s featured Britcar Class 2 Marcos Mantis is built around a space frame with a fiberglass body and is powered by a standard LS7, 7 litre / 427 cui V8 engine mapped to produce 505hp on 98 octane unleaded fuel which is transmitted to the rear wheels through a 6 speed Holinger sequential gearbox.

Marcos Mantis GT2, Head, Tilley, Britcar, Castle Combe

Additional features include electric power steering, quick fill fuel tanks, quick lift air jacks and spec 18″ Dunlop slick or wet tyres on center lock wheels, four of which can be changed in 22 seconds.

Marcos Mantis GT2, Britcar, Castle Combe

With a weight of 1050 kgs / 2315 lbs the car will reach 60mph in an ear splitting 3.5 seconds and a top speed of 190 mph.

Marcos Mantis GT2, Head, Tilley, Britcar, Castle Combe

Sam Head and Kyle Tilley drove the #26 car entry for most of 2011 and they are seen above at Castle Combe on the 27th of August where they finished a low 20th overall from a more representative 8th on the grid, this a month after Henry Fletcher and Raphael Fiorentino had finished 2nd overall and 1st in Class 2 at Spa.

At the seasons end the Topcats Class 3, 50 hp less, #36 Mantis finished 2nd in the Britcar Championship with Owen O Neill, Henry Fletcher, Jon Harrison and Raphael Fiorentino all taking turns at the wheel during the season and the #36 was classified 3rd with Jeff Wyatt replacing Kyle for one round at Snetterton and Neil Huggins and Jon Harrison being the cars drivers in the championship final at Brands Hatch.

Topcats appear to have retired their LS7 powered Mantis cars from competition at the end of 2012 after their 2 cars both now running in Class 2 finished 3rd and 11th in the Britcar Championship.

Wishing Cheryl a Happy Birthday.

The Ultimate 25 – Lotus 33 #R10

The Coventry Climax V8 powered Lotus 33 was developed from the 1963 Championship winning Lotus 25 for the 1964 Formula One season to take advantage of the latest 13 inch diameter broad tread tyres which had been developed by Dunlop.

Lotus 33, Autosport International, NEC, Birmingham,

Designer Len Terry described the 33 as “stronger, stiffer, lighter, simpler” than the 25 and noted it was “a lot quicker too”.

Lotus 33, Autosport International, NEC, Birmingham,

After problems with hydrogen embritteld chrome plated suspension had been over come Jim Clark used the Lotus 33 to score a season high 5th in his 4 1964 Lotus 33 starts, after winning 3 1964 Championship races in the older Lotus 25, similarly Walt Hangsen finished 5th in the 1964 US Grand Prix at the wheel of a 33.

Lotus 33, Autosport International, NEC, Birmingham,

By 1965 Lotus had got it’s act together again and after Jackie Stewart gave today’s featured chassis R10 it debut in the non championship 1964 Rand Grand Prix, where he retired from heat one for which he qualified on pole and finished 1st in heat two after recording fastest lap, team leader Jim Clark took over the car for the 1965 championship opening South African Grand Prix for which he qualified on pole, set fastest lap during the race and won.

Lotus 33, Autosport International, NEC, Birmingham,

Jim repeated the feat of pole, fastest lap and winning driving R10, seen in these photographs at the Autosport International earlier this year, in the 1st heat of the non champinship Race of Champions at Brands Hatch but understeered, push, off at Bottom Bend while being chased down by Dan Gurney in heat two bringing R10’s in period racing career to a premature end.

Lotus 33, Autosport International, NEC, Birmingham,

Jim Clark missed the 1965 Monaco Grand Prix opting instead to start and win the 1965 Indianapolis 500 with the Len Terry designed Ford Fairlane powered Lotus 38.

Lotus 33, Autosport International, NEC, Birmingham,

On returning to the 1965 Formula One championship trail Jim drove Lotus 33’s to five consecutive victories in Belgium, France, Britain, The Netherlands and Germany which was enough to secure the 1965 World Drivers Championship despite the fact that he posted retirements in the final 3 races of the season !

Jim Clark remains the only man to have won the Indianapolis 500 and the World Drivers Championship in the same season, of the other Indy 500 winners only Graham Hill, Mario Andretti, Emerson Fittipaldi and Jacques Villeneuve have also won World Drivers titles.

Thanks for joining me on this “The Ultimate 25” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again tomorrow when I’ll be taking a break from Maserati Monday’s to bring you an unusual Hot Champ. Don’t forget to come back now !

Four Independently Sprung Tons – Bluebird Proteus CN7

Between 1955 and 1964 Donald Campbell, son of Sir Malcom, set 6 World Water Speed records in the remarkable jet powered hyroplane Bluebird K7.

Equally remarkably during much of this time Donald was also raising the funds for todays featured Bluebird-Proteus CN7 for an attack on the 394 mph land speed record which had been set by John Cobb driving the Railton Mobil Special in September 1947.

After Donald had set a new water speed record of 202 mph with his K7 hydroplane he asked it’s designers Lew and Ken Norris if they would like to design and build today’s featured record breaking car.

Bluebird-Proteus CN7, National Motor Museum, Beaulieu,

The Norris brothers set about devising possibly the worlds most sophisticated motor vehicle with a monocoque chassis housing a modified 4,450hp Bristol-Siddeley Proteus turbo prop motor that delivers power through two gearboxes to the front and rear axles which in turn drive the independently sprung 52 inch Dunlop wheels.

The Norris Brothers and many since anticipated that the Bluebird Proteus CN7 would be capable of 500 mph.

Despite the cars front wheels having only a 4 degree turning angle Donald Campbell gave the CN7 it’s first public outing at Goodwood in 1960 managing a couple of demonstration laps. With the engine running at idling speed it still managed to reach 100 mph on the straight.

Bluebird-Proteus CN7, National Motor Museum, Beaulieu,

Donald’s first attempts to break the World Land Speed record at Bonneville in 1960 ended with an accident in which he suffered a fractured lower skull and a broken ear drum.

While recuperating Donald learned to fly and rebuilt CN7 for a Land Speed Record Attempt in 1963.

Bluebird-Proteus CN7, National Motor Museum, Beaulieu,

Lake Eyre in Australia was chosen not only because more space was available by also because it had not rained there for 20 years… until Donald and CN7 turned up.

In 1964 Donald returned to Lake Eyre and without a properly dried out salt surface managed to raise the World Land Speed Record to a disappointing 403 mph, nearly 100 miles an hour short of his target.

On the 31st of December 1964 Donald became the first man to set World Speed Records on Land and Water in the same year when he set his final new record aboard K7 of 276 mph on Lake Dumbkeyung also in Australia.

Bluebird-Proteus CN7, National Motor Museum, Beaulieu,

The regulations for land speed records were relaxed to allow thrust powered vehicles without driven wheels shortly after Donald set his record in the four wheel drive CN7.

The Norris brothers were envisaging rocket propulsion for a new Bluebird Mach 1.1 vehicle when Donald was killed aboard K7 on Coniston Water in England while he was trying to raise the World Water Speed record on January 4th 1967.

Bluebird Proteus CN7 is seen in these photographs at the National Motor Museum, Beaulieu where it is usually to be found when not out on loan.

Deserts, Malaria And A Leopard – Austin Twenty

In 1919 Herbert Austin launched his Austin Twenty which he hoped would be the back bone of what he hoped would be a single vehicle policy requiring only variants of the Twenty to be manufactured.

Austin Twenty, Heritage Motor Centre,

Novel features for the UK market of the Twenty included a central gear change and coil ignition, both of which were to be found on the Hudson Sir Austin had driven during the 1914-18 war years.

Austin Twenty, Heritage Motor Centre,

Unfortunately the combination of the British governments Horsepower Tax on the 4 cylinder 3621cc / 220cui motor and high production costs meant Austin had to scale down his hopes for the twenty and expand his model range by introducing 12hp and 7hp models.

Austin Twenty, Heritage Motor Centre,

The Twenty was initially advertised for £485 and by 1922 when today’s featured Twenty was built the price had risen to £625.

Austin Twenty, Heritage Motor Centre,

In 1932, when today’s featured car was ten years old, it was purchased for £33.00 by a Mr AE Filby who fitted it with stronger rear springs so that it could carry 12 gallons of water and a total of 50 gallons of fuel.

Austin Twenty, Heritage Motor Centre,

Mr Filby then set off from London on a four year journey across Europe, the Sahara through East Africa all the way down to Cape Town… and back !

Austin Twenty, Heritage Motor Centre,

During his 37,000 mile adventure Mr Filby caught malaria in Kenya and his dog was eaten by a Leopard, but apart from a broken leaf spring, u-bolt and head lamp fittings the 58 mph Austin fared well on a single set of Dunlop tyres.

Austin was so impressed they bought the car from Mr Filby as an excellent example of dependability. In 1938 Mr Filby repeated the journey with an Austin 12 he bought for £20.
