Original GT40 at Festival Of Speed

Fantastic visit to the Festival Of Speed last week. Picture shows an original GT40 #1084 as it screams up the hillclimb.

If you want something doing!

On finishing my CAV GT40 I’ve always had a problem with the A/C System.  I would switch the A/C on and you would hear the compressor clutch click and cold air would come out of the ducts.  A few seconds later the compressor clicked off.  This continued, compressor clicked on and then off again.  I didn’t do the initial installation of the A/C system, I got on independent company to do the pipe fittings, wiring and pressurising of the system.

Anyway last weekend I’d had enough of “melting” in the car so I decided to fix this problem once and for all.  My first thought was that the problem was low pressure so I called in at the local Halfords for and A/C “top-up” kit and tested the pressure with the gauge on the kit.  To my amazement the pressure in the system was very high, great I’ve found the problem.  So I proceeded to remove some of the pressure from the system. After retesting the pressure a test of the A/c was in order.

Unfortunately, the same problem occurred, but I noticed that the fan didn’t come on when the compressor clutch engaged.  On closer investigation I found a bad earth on the fan wiring. Another test of the A/C system was done and this seemed to resolve the problem, however the air did not seem to be very cold.  Anyway I had another look round the A/c System and noticed that the switch that shut of the heat to the heater unit was working the wrong way round.  A/C On, hot water was supplied to the heater. A/C Off, hot water was shut off to the heat. 

After sorting this problem I again tested the system and it worked perfectly.

The moral of the story is “If you want something doing right do it yourself”.

Couple of GT40 Pictures from Le Mans

GT40's For Sale

Your chance to own the very last Abbey Panels-chassised GT40 sold by JWAE. Yes, it’s the beautiful 1086, about as close to 1075 as you’re likely to get, and still wearing the Gulf livery JWAE gave it when new.
Not to your liking then have a look at J.S.Allen's web site for other cars for sale. John has written a number of books on the GT40 and his site is full of information and images.

My Car

Finally got round to taking a photograph of my car. For the GT40 guy's out there sorry its in gulf livery and not a unique colour, but hopefully the detailing is somewhere near the original.

The engine is a Ford 396 stroker engine direct from Ford Motorsports in the USA. If you believe the spec from Ford the engines good for 420bhp. Fitted with Holley carb and mated to a new Audi Gearbox shipped in from CAV in South Africa.

If your going to the Festival Of Speed -Goodwood next week you might see it on the motorway travelling down from Leeds on Thursday and back on Monday. Hopefully should have some photos from FOS when I get back.

Holley Accelerator Cam Kit

Ive been having trouble with bad hesitation during initial acceleration. After doing some reading of my Holley manual it appeared that the problem could be due to the profile of the accelerator cam that was fitted to the carb. I decided to purchase a cam kit and started to experiment with the different profiles. After a few blasts up and down the local carriage way to warm the engine up, I pulled into a layby and changed the orange cam to the blue one. Very simply job to do at the side of the road, one screw, remove cam and fit the new one.
Jumped back in the car and went for a test drive. Well the difference was amazing, the hesitation had gone completely.
