Traffic Light King - GMC Syclone

Max Grabowsky established the Rapid Motor Vehicle Company on the 22nd December 1901 which built a truck powered by a single cylinder motor. In 1909 the company was taken over by General Motors to form the General Motors Truck Company from which the GMC Truck brand was born. In 1916 a GMC Truck was driven from Seattle to New York City in just 30 days, ten years later a 2 ton GMC Truck took five days and 30 mins to travel from New York to San Francisco.



In 1990 GMC identified a niche market for a 'performance' truck based on the GMC Sonoma complete with lowered suspension, four wheel drive, fog lights and under the bumper corner spoilers.



The Syclone model was powered by a 280 hp 4.3 litre / 262 cui turbocharged V6 motor that was coupled with a 4 speed automatic transmission. ABS brakes, to keep all those horses under control, were used for the first time on an all wheel drive truck application.



Volkswagen Golf / Rabbit GTi inspired, to European eyes, red detailing inside and out was rounded off with 16 inch alloy wheels carrying comparatively low profile tyres.



Car & Driver famously pitted the $26,000 Syclone against a $122,000 296 hp Ferrari 348ts and in all the acceleration tests up to and including the 1/4 mile drag the Syclone came out best only loosing out with a top speed of 126 mph against the Ferrari's 166 mph !



Built in Troy MI by Production Automotive Services, unlike the regular Sonoma which was built in Shreveport LA, the only downside of the Syclone was that it's lowered suspension limited the carrying capacity to just 500 lbs, still considerably more than a Ferrari, but considerably less than that 1700 lbs plus of a regular GMC Sonoma.



It is thought just 2998 Syclones were built between 1991 and '92, with just 3 made in 1992 ! 113 are thought to have been exported, with 31 returned, making today's vehicle seen in Bristol one of just 82 Syclones thought to be outside the USA.

Patrick Bedard of Car & Driver summed up the Syclone as the pick up that would 'do a Ferrari blur on the local scenery' and 'makes this capability seem like a perfectly wonderful idea.' Sounds good to me, a very good idea indeed.

Big Block Pagoda - Iso Grifo Super 7 Litri Series I

Iso Rivolta was the brainchild of Italian Engineer Renzo Rivolta who had been responsible for Isothermos refrigeration units prior to World War 2.



Wishing to move into motorised transport markets Rivolta developed a range of expensive but well built durable motorcycles from 1948 to 1961.



In 1950's Renzo developed his best known vehicle the Isetta Bubble Car that was manufactured by Iso in Italy and under licence by Velam in France, Romi in Brazil and most successfully by BMW in Germany.



After leaving Ferrari in 1961, where he had been responsible for the fabled Ferrari 250 GTO, Giotto Bizzarrini set up his own design studio and in 1963 designed the mechanical architecture of the Iso Griffo A3/L. The Grifo,launched in 1963, featured a blueprinted, a process of disassembling a motor then rebuilding it with all the engine parts matching the exact original engine blueprint design specifications for optimal performance, 400 horsepower small block Chevrolet motor.



In 1968 the Grifo was made available with a 435 hp Chevrolet 427 big block motor, requiring the pagoda like air scoop on the bonnet to accommodate the extra height of the larger engine,



along with extra ventilation in the front wings to keep the motor cool, seen on this vehicle which was built in 1969.



The Grifo 7 Litri was said to be capable of 186 mph.



It would appear that just 67 of the 7 Litri Series I vehicles were produced from 1968 to 1970 when the rarer Series II Grifo's with pop up head light covers were introduced.



The combination of rarity, Bertone styled beauty and mechanical simplicity, a result of using many proprietary parts including the engine and gearbox, makes the Grifo a relatively easy to maintain collectible car.

Sprinzel Lawrence Racing - Morgan And Triumph SLR

Towards the end of 1963 former British Rally Champion and Racing Driver John Sprinzel joined forces with noted engineer and Morgan racer Chris Lawrence, under the Sprintzel Lawrence Racing (SLR) banner, to design and build a sports car based on a Triumph TR4 powered ladder frame Morgan +4, with a similar chassis to the one that Chris had co driven with Richard Shepherd - Barron to a class victory at Le Mans in 1962.

From what I can gather Triumph racer John Hurrell managed to secure some funding for the SLR team and after seeing Chris Spenders drawings for the proposed Williams and Pritchard built bodywork for the Morgan & Triumph SLR car John asked if a similar SLR body could be fitted to his Triumph TR4 that he had been racing since 1960.

As things worked out the Triumph with a slightly shorter chassis was the first to be taken to Williams and Pritchard to have an aluminium SLR body built around it. Neil Dangerfield is known to have been winning races in this car as late as 1967 and the Triumph SLR went down in the record books as being the last to leave the start line at Goodwood as the scratch entry in the last, handicap, race held at the Circuit before it closed in 1966.

Neil drove the Triumph SLR 31 years later at the request of Lord March on a 3 lap demonstration when the Goodwood circuit was reopened in 2006.

Note the registration SAH 137 was originally issued to a Triumph TR3A owned by Jim Hurrell who transferred the number to the Triumph TR4 that was fitted with the SLR body and later sold it to Neil.

The first of the Morgan SLR's powered by a Triumph TR4 engine and featuring beefed up hubs along with the benefits of other lessons learned from Chris Lawrence's Le Mans experience appears to have been built around a 1961 chassis for Gordon Spice a well known figure in British racing circles who eventually built and ran his own Spice Group C cars in the late 1980's.

After just 3 laps of Goodwood Gordon crashed his new car in 1964, necessitating a complete rebuild making this red car both the first and last of the Morgan chassied SLR's built. In 1975 then owner Sir Aubery Brocklebank suffered burns after a fuel leak in this car caught fire at Silverstone. The car was subsequently painted fire engine red.



(Morgan & Triumph SLR II)

The second Morgan and Triumph SLR was built for Pip Arnold, legend has it that this car was never painted because soon after delivery it was due to be raced at Spa and so the aluminium bodywork was merely polished. In the early seventies this car was caught in a severe garage fire and rebuilt by well known fabricator of racing cars Maurice Gnomm.

The third car was built for Chris Lawrence himself and set an all time class lap record at the very last race meeting held at Goodwood in 1966. Chris Lawrences old car also won a race during the Goodwood Revival in 2006.

All three of the Morgan And Triumph SLR's were united possibly for the first time ever at the 2010 Silverstone Classic. As John Sprinzel rhetorically asked after seeing these photo's "They were good looking cars weren't they?"

From The Nostalgia Forum I'd like to thank David Lawson and Bob 'Bauble' Bull for the use of their photographs, Pete Stowe, Kurt O and Sharman for responding to my TNF Triumph SLR thread garyfrogeye for contacting John Sprinzel and Tim of the Willliams and Pritchard website for their kind replies.
Thanks also to Andy Downes and in particular Neil Dangerfield of the tr- register forum for his post on the order in which the cars were built to Richard 'redmorgan' Gilbert for the use of his photo, John "sprinty" and Steve N22MOG L and everyone at Talk Morgan who responded to my post.

Thanks for joining me on this SLR edition of 'Gettin' a lil' psycho on tyres' I hope you will join me again tomorrow for a look at an exotic Italian that needs a cool pagoda airbox to cover a big block V8. Don't forget to come back now !

Ferrari Turned Ugly - Ferrari 312 P #0876 ?

Some months ago I said that after Niki Lauda tested the proposed Ferrari 312 P sports prototype for 1974 he advised Enzo Ferrari that if he wanted to win the World Formula One Championship that he ought to drop the Sports Prototype Programme.



(Ferrari 312 P 1974 Spec, Copyright holder unknown image will be correctly credited or removed upon request.)

The photo above shows Niki Lauda testing the 1974 312 P that is thought to be the work of Mauro 'Fury' Forghieri who simultaneously was working on turning the Formula One Ferrari 312 B3 into a competitive proposition.

It has emerged that it was more likely that Niki and Luca de Montemezolo between them successfully convinced Mr Ferrari that continuing the sports prototype programme was not a good idea.



(Ferrari 312 P 1974 Spec, Copyright holder unknown image will be correctly credited or removed upon request.)

As can be seen above even after the alleged advice and Lauda's test drive, the car, seen here with Niki's team mate Clay Regazzoni at the wheel, was developed further with the wide front wing being added before the car was dropped and plans to enter the World Sportscar Championship were abandoned.

It would appear 1974 spec 312 P was based on a short wheel base 1971 312 P chassis, probably #0876, this car, with it's even more distinctive driver side cooler arrangement, than we saw in last weeks 1973 312 P blog, was never raced and has not ever been seen in public.

It is thought likely the car got destroyed on the orders of Enzo Ferrari early in 1974 before the Italian Tax Authorities were due to pay Mr Ferrari a visit.

My thanks to everyone on the 1974 Ferrari 312PB 'evo' thread at The Nostalgia Forum who contributed to this blog.

Giant Killing Potential ? - Jedi Mk4

Today we are looking at a Jedi Mk4 run by 2 time 1000 cc Monoposto Champion Arty Cameron that appeared at Castle Combe for the Free Single Seater Series the week before last.



Arty is from a big racing family who's father Tim started racing in 1958, 3 of Arty's 7 siblings also compete.



The Jedi Mk4 was designed by racer John Corbyn and built in Wellingborough to accommodate a variety of motorcycle engines, Arty uses a 1000 cc / 61 cui Yamaha R1 motor which produces 183 hp



that is transmitted to the rear wheels by chain drive.



Thanks to a high power to weight ratio, car and driver 400 kgs a potential acceleration time of 0 - 60 in under 3 seconds is possible,



Arty beautifully translated this potential into this memorable start at Castle Combe two weeks ago in which starting from 5th he led the opening lap



against faster Formula 3 cars with larger tyres and more powerful motors with ease during an all comers race.



The Jedi flew around the corners, Arty displaying masterful car control as it did so.



Unfortunately the giant killing act was judged to have been the result of a jump start and Arty's 10 second penalty became irrelevant after his engine grenaded, possibly the result of an oil leak during qualifying.

I look forward to seeing what Arty can do next time out which I hope will be next weekend at Castle Combe for the August Cup.

If you have an open wheel vehicle that can meet the 108db limit, and I have seen some 7 litre V8's and an 8.3 litre V10 meet that requirement recently, why not come along to Castle Combe and join in the fun. Should you looking be looking for a driver, you could do worse than give double Monoposto Champion Arty a call, he is certain not to disappoint.

My thanks to Geoff E, Simon Lewis and JMH of The Nostalgia Forum for coming up with additional details for today's post.

Hope you have enjoyed today's Monoposto edition of 'Gettin' a lil' psycho on tyres' and that you will join me again tomorrow. May the force be with you and don't forget to come back now !

Bi- Parting Tailgate - Volvo Amazon Estate / Station Wagon

Last week I looked at the Volvo Amazon, no sooner had I written the blog than I came across this Estate / Station Wagon version with Dutch plates.



Unlike most modern vehicles of this type the Amazon had a two piece tailgate, the bottom half opens down to form a loading platform while the top half opens up a feature common to many US Estate Station wagons. Like the Mini introduced in 1959 the rear licence plate is conveniently hinged at the top so that one can carry longer loads with the tailgate down without attracting the ire of traffic law enforcement agencies.



The Amazon Estate / Station wagon was launched in 1962 seven years after the original Amazon Saloon / Sedan, and shared with it's 3 box sibling body work made of phosphate treated steel to improve paint adhesion and heavy use of undercoat and anti corrosive oil treatment.



Between 1962 and 1969 Volvo manufactured 73,000 Amazon Estate / Station wagons.

Awaiting TLC #2 - Rover 75 P4

The Rover P4 range of vehicles was introduced in 1949 to replace the interim out dated P3 vehicles which had been rushed into production in 1948 as the Rover company sort to rebuild itself as a vehicle manufacturer having spent the years during World War 2 manufacturing aircraft.



Drawing inspiration from the 3rd generation Raymond Loewy designed Studebaker Champion launched in 1946, at the request of the Wilkes brothers who owned Rover, Gordon Bashford was responsible for what was known in the factory as the P4. The original P4's came fitted with a central spot lamp mounted in the grill, but this feature was dropped early in production which eased the difficulties keeping the engine cool.



The P4 was continually being upgraded and from 1954 a distinct MkII version was available that was then restyled again into the form shown in these photo's in 1957, a Mk 2.2 if you will.



Because of material shortages immediately after WW2 these vehicles incorporated a high percentage of aluminium content and were to be seen in competitions of the day including the 1955 Mille Miglia in which Lando Barsotti brought his #347 Rover 75 P4 in 271st. The 75 seen here was powered by a 2.2 litre /136 cui 6 cylinder motor featuring the same overhead inlet valves and side exhaust valve design as had been a feature of the earlier P3.



The final MK II P4's were produced in 1959 with 9,974 Mk II's produced over it's five year production run.

I spotted this particular vehicle at the back of the Atwell - Wilson Motor Museum. I am not sure what they planned to do with it, good working examples of the type tend not to fetch more than £ 2000 so the cost of restoration would appear to be a little prohibitive.
