Variable Inlet Cam Phasing - Nissan Skyline GT R33

This 1996 Skyline GT R33 is a two wheel drive forth generation Skyline. The front bumper and spoiler on this one appears to be an after market item.



Power was delivered by an RB25DET 250 hp twin turbo 2490cc / 151 cui straight 6 engine which featured variable inlet cam phasing ( NVCS ). Many of these vehicles have been sent to engine specialists for radical tuning, racing versions of these engines have shown over 500 hp.



It is thought that 217,133 R33 Skylines were produced from 1993 - 1998 and sold in Japan, Hong Kong, Australia and the UK, although officially imported many more are thought to have arrived in the UK as personal 'grey' imports.

Hope you have enjoyed today's NVCS edition of 'Getting a little Psycho on Tyres' and that you'll join me again tomorrow. Don't forget to come back now !

Nailhead Power - Kurtis Buick 500X #3

Today's photograph by Carlyle Blackwell was purchased by Ed Arnaudin back in the 1950's.



Photo Carlyle Blackwell, Publised Courtesy Blackwell Archive, for sales enquiry's please e-mail infoATpsychoontyres.co.uk and your contact details will be forwarded to the Blackwell Archive.

Bill Murphy's #96 Kurtis Buick 500X seen in this photo, probably at San Diego in July 1956 where Bill won two races, is thought to be the 3rd of 12 500X chassis designed by Kurtis - Kraft who were well known for building successful open wheelers for the Indianapolis 500.

With a 96" wheelbase the 4120 chrome moly tube chassis of this model featured 4 bar torsion suspension and was a variation of the KK500C Indianapolis car covered in a hand formed aluminium body secured with Dzus fasteners.

The Kurtis was powered by a 5276 cc / 322 cui nailhead Buick V8 which is said to have produced between 300 (Bill Murphy) and 400 hp (Carol Shelby), this engine featured Hilbron fuel injection and was connected to a Jaguar 4 speed gearbox with the aid of Zidar adaptors.

The car was raced successfully by Bill Murphy from August 1955 to September 1957 during which time he scored 9 overall wins and 18 class wins. Murphy's employee from his Buick Dealership the Indy Car driver Sam Hanks was asked to shake the car down before races and then acted as engineer and crew chief for Bill during the races.

This car is said to have sat on Bill Murphy's lot until 1979 and resumed it's winning ways in 1980, since then this vehicle has appeared at Pebble Beach, Murphy never took risks on the track and the car is thought to have survived to the present day in original condition with no more than a fresh lick of paint.

Bill Murphy born in Alaska, was a successful UCLA dropout who built a huge car dealership empire which included Desoto-Plymouth and what from 1962 - 1965 was known as the worlds largest Buick dealership in Culver City.

Bill who was over 40 years old when he raced the Kurtis, which thought was capable of over reaching speeds 180 mph, business partner Shelby reckoned that Bills Kurtis was more powerful than any contemporary Ferrari or Maserati.

My thanks to Ed and Steve Arnaudin for forwarding Carlyle Blackwells photograph and to R Shelby and Coneptcarz for details about Bill and the 500X.

Ferrari by David Bailey - Ferrari 550 Maranello GTS

Some of you who read my Rowdy blogs may remember a blog about the 2002 celebrity Prodrive Ferrari 550 Marranello GTS (03).



That chassis took part in at least 42 Races in the GT/GTS class for at least four different teams from 2002 to 2006 and had a host of celebrity drivers including,



Colin McRae World Rally Champion, British Touring Car Champions Rickard Rydell & Alain Menu, British, Luc Alphand former World Cup Skiing Champion and Dakar winner, David Brabham Japanese GT Champion and Le Mans winner 2009, Jan Magnussen Danish Touring Car Champion, Danica Patrick queen of IRL, Darren Manning IRL driver, Christophe Bouchut 1993 Le Mans Winner, and one of my former racing instructors Tim Sugden former British and Asia Pacific GT Champion.



Prodrive prepared a batch of 20 550 Maranello GTS's for racing in Europe and the States where they were regular winners in the GT/GTS class in 2001.



In 2003 today's #88 550 Maranello GTS Chassis ZFFZR49B000108462, the 6th of the 20 Prodrive built, was driven by Thomas Enge, Jamie Davies and Peter Kox,



with around 750hp coming from it's V12 engine,



beat the Corvettes by 10 laps at the Le Mans 24 hour race winning the GTS class coming home 10th overall.



This vehicle entered exclusively by the Prodrive team is known to have run in at least 9 races in 2003 in all bar one carrying the #88, this chassis carried the #08 in it's last known final at Petite Le Mans.



When the effervescent Jackie Irwin, who has petrol running through her veins, told us on my recent visit to the Prodrive factory we were allowed to sit in some of the vehicles parked in the display area like a 12 year old I headed straight for the 550 Maranello,



the experience of sitting in this fabulous car was an odd mixture of agony and ecstasy, the seat was made for someone with hips the size of a 12 year old, yet at the same time the purposefulness of every last detail inside the vehicle sent my mind straight to Le Mans, by some strange fate I also found my self posing for this photograph taken by David Bailey , I am sure Twiggy would have felt far more comfortable in the seat, but then I doubt she would ever find herself posing for David Bailey of the Bristol Pegasus Motor Club.

My thanks to David Bailey, everyone at the Bristol Pegasus MC and Prodrive who made my visit such an interesting day out.

Hope you have enjoyed today's David Bailey edition of 'Gettin' a lil' psycho on tyres' and that you will join me again tomorrow. Don't forget to come back now !

Heavyweight - Jaguar E- Type 3.8 Coupe

Call me a hopeless romantic but there is something I find irresistible about the notion of walking into a showroom purchasing the fastest vehicle they have in stock, adding a couple towing eyes, a fire extinguisher roll cage and 5 point harness and ignition cut out switch and heading down to the nearest race track.



This kind of racing used to be called stock car racing in the US and Production racing in the UK.



Today's stunning 1961 E-type 3.8 litre Coupe has been kept in more or less original trim since new.



It still has an all steel shell and opening panels.



Until recently the current owner; ex power boat racer, Michael O'Shea has been racing a 1958 XK150S, he has a decades experience racing Jaguars and a couple of years racing a Cooper - Maserati.



Michael first started racing karts at 12 but did not start racing cars for another 34 years.



Racing has been in Michael's blood all his life his Dad was the mastermind behind the O'Shea Racing Organisation which ran a car for a then unknown, future world champion, Jack Brabham.



Michael will be racing his car in the new HSCC Jaguar E-Type Challenge a series created to cater just for E-types on their 50th Anniversary.

My thanks to Jaguar World and Classic & Performance Car for additional information.

Hope you enjoyed todays Heavyweight edition of 'Gettin' a lil' psycho on tyres' and that you will join me again tomorrow for Ferrari Friday. Don't forget to come back now !

Sick Bag Not Included - Prodrive P2

In 2006 David Richards tasked every department in the Prodrive Group with developing the Prodrive P2 into a fully functional concept car in order to demonstrate " the perfect manifestation of what happens when our inspirational ideas combine with our innovative approach.”



Development from designs by Peter Stevens, whose portfolio includes the Jaguar XJR 15 and McLaren F1, to fully functioning vehicle took just 9 (nine) months.



Prodrive started by using a much modified All Wheel Drive Subaru R1 platform around which to build the P2.



Under the hood lurks a 345 hp turbocharged Subaru flat four taken from the Subaru World Rally Championship (WRC) programme complete with Prodrives Anti Lag System (ALS) tuned for the road that minimises turbo lag by burning fuel in the exhaust system at low rpm which keeps the turbo turbine spinning at high speed. Such systems which increase the throttle response of turbocharged vehicles were banned from Formula One in 1981.



The P2 also uses a modified version of the Subaru (WRC) drive train which features Prodrives ATD™ system which compares what the driver is expecting with what the vehicle is providing. The system modulates torque to individual wheels using a differential control system.

In a four wheel drive application such as the P2, if the car is understeering / pushing, then the system will deliver more torque to the back wheels, making it behave more like a rear wheel drive car; if the car is oversteering / loose then more torque will be delivered to the front wheels. ATD™ enables the car to be driven through corners at much higher speeds.



When a well known large presenter of a well known motoring programme tried the P2 with the ATD™ switched on he apparently drove the P2 in such a tight circle at such high speeds he made himself ill and had to stop the car and open the door to spill his diced carrots and peas on the tarmac.



With a power to weight ratio of 350 hp per tonne the P2 can reach 62 mph in 4 seconds and a top speed of 174 mph.

Prodrive estimated that it would have been able to retail the P2 for around £40,000 / $ 65,000 in 2006, but declined to manufacture the vehicle themselves.

Hope you have enjoyed the ride in today's ATD™ edition of 'Gettin' a lil' psycho on tyres' and that you'll join me again tomorrow. Don't forget to come back now !

Coming up Short - Triumph TR8 Twin Turbo

All of motor sport is littered with heroic failure and there is possibly none less understandable than the Janspeed Engineering Triumph TR8 twin turbo, when one considers John Buffum's success with the TR8 on the US Rally Stages in North America and Bob Tuliis equally outstanding success with his TR8 on the race tracks, so much in fact Bob was forced into a successful switch from SCCA to IMSA series.



Like the Buffum and Tullis programmes Janspeed's Le Mans programme had absolutely zero factory backing but unlike Buffum and Tullis, Janspeed did not even have a budget to run the car let alone test it.



Legend has it that this vehicle started life as a left hand drive test hack used by Janspeed on behalf of British Leyand, when the tests had been completed Jan Odour acquired the vehicle with the intention of preparing it for a British modified series, however a change of rules in that series, around 1977, led Jan Odour to attempt something far more ambitious namely to take on the onslaught of Group 5 Porsche 935's in the World Sports Car series.



The Janspeed TR8 ran with a dry sumped twin turbo version of the all alloy Olds/Buick V8 design purchased by Rover and was said to produce over 500 hp, but it failed to set a qualifying time on it's debut at Silverstone in 1980, where the car was loaned out to ADA Engineering in a vane effort to get the car onto the track.

Later at Le Mans despite being recorded travelling in excess of 200 mph on the Mulsanne the car failed to qualify.



I remember looking forward to seeing what the TR8 could do when I returned to Silverstone in 1981, despite arriving in time to catch qualifying I was already too late, the car had been crashed and withdrawn from the race much to my disappointment.

Later in 1981 the car ran again at Brands Hatch where it qualified but failed to finish after a spin and a stall, unfortunately I was in Germany at the time so I never did get to see possibly my all time favourite Triumph run.

Hope you have enjoyed today's twin turbo edition of 'Gettin' a lil' psycho on tyres', and that you'll join me again tomorrow for a look at a truly unique vehicle that was perhaps just an on board sick bag short of reaching production. Don't forget to come back now !

Inspiration and Innovation - Prodrive Factory Visit

I was privileged to join fellow members of the Bristol Pegasus Motor Club and Barrie 'Whizzo' Williams on a factory tour of the Prodrive Factory over the weekend.



David Richards a qualified chartered accountant and 1981 World Championship Winning Rally co-driver who started his business as a motor sport consultant in the middle east, says of his company that it's purpose is to 'inject excitement'.



That injection of excitement is backed with 25 years of Championship winning motor sports success that includes rallying



and racing ...



to the very highest levels including two spells in which David Richards ran teams in Formula One.



In 2006 Prodrive built a fully working concept car, but declined to put it into production,



After numerous successes running Aston Martin racing teams ...



David Richards led a consortium of investors in a $925 million take over of Aston Martin in 2007,



a company of which he is now the Chairman.

It was uplifting to see British engineering is alive and well in Banbury, Oxfordshire with a fascinating range of activity including the assembly of a range of competition vehicles, computer operated machining of a huge variety of items from solid blocks of material, and truly mind boggling assembly of competition spec wiring looms, if your into engineering and or motor sport the Prodrive tour run by the effervescent Jackie Irwin, who has petrol running through her veins, is an absolute must.

My thanks to everyone at the Bristol Pegasus Motor Club who organised the tour including Andy who kindly did the driving honours.
