Yes ! A 928 ran in the « 24h du Mans ». And even if it seems a strange idea, it did well. It finished the race both times it took part. Let’s take a look at the real car before talking about the 1/43 scale model.

1983
Everything started in the autumn of 1982. A mechanic from Limeil-Brevannes, Raymond Boutinaud bought a slightly damaged 928. He wanted to repair it for everyday use, but he had also been thinking of taking part in the 24 hours race for a long time. He didn’t want to prepare a 930, so with a few friends, he decided to prepare the 928 : operation 928 L.M. had begun...

The preparation of the car was very short because a sponsor backed out at the end of the winter. The main idea was to lighten the car (to 1235 kg which is the minimum weight for group B) and to boost the engine a bit (350 h.p.). The assistants were putting the finishing touches to the electric wiring during the "weighing in" for the event.
During testing, the car stood out  … by clocking the slowest times. The best lap was made in 4’35’’94, which is 177,769 km/h average (110,336 mph). The car was recorded at 267 km/h (166 mph) on the straight line of the Hunaudières. This is a huge difference with Jacky Yckx’s 956 which obtained the pole position in 3’16’’56 (an average of 246,560 km/h (153,20 mph)). The fastest speed was signed by another 956 (Newman N° 12) with 371km/h (230 mph). This is a difference of more than 100 km/h (62 mph) between the slowest and the fastest !

essais The car during testing

The pilots were Raymond Boutinaud, Alain Lepage and Patrick Gonin.
The race started well : at 19h00 the 928 was 29th on 49 cars, but the front left hub broke and it took 3 hours and 20 minutes to make and fit a new piece. The car then drove well to the end.

Here are the race events :

La course the car during the race
Bilan :
After 24 hours, the Porsche is 21st but non classified  because the distance driven was too short : 3193,599km  (1984,4 miles) at an average of 133,066km/h (82,68 mph).
1984
Raymond Boutinaud, encouraged by the previous year’s race, decides to have another go. After reinforcing the hubs (911 parts modified), and boosting the engine, he takes the car to Le Mans.

Le pesage "le pesage"

It is still last in testing, but laps in 4’28’’74 (182,531 km/h (113,41 mph) average). The improvement is very noticable even if the car is way behind Bob Wollek (3’17’’11 with his Lancia LC3)
This time, the car is driven by Raymond Boutinaud, Philippe Renault and G.Guinand.
There isn’t much to say about the race, the car runs well until 10 o’clock the next morning. This time, it’s the left cylinder head gasket which is tiring. The team has to slow down till the finish.

Bilan :
This time the car is classified. It is 22nd (out of 22...) in general and  3rd in B group  with 3475,991 km (2159,88 miles) at an average of 144,832 km/h (89,995 mph). The best lap was timed at 4’27’’7 (better than in testing). The car used 35,67 litres average per 100 km (7,92 mpg).

Conclusion :
The 928 L.M. adventure stops there. Raymond Boutinaud decided not to try again. He still owns the car, even if, when I saw it in 1995, it looked more like a 5000 piece puzzle. His still has the intention to race it in GT class.

he car has of course been made into kits. Provence Moulage offered two versions (1983 & 1984) in the eighties. They are correct apart from a slight mistake in the colour for the 1983 version. In that year, the car was very well painted. The background colour was white, but you can only see it at the back and on the roof. For the rest, there is a superb arlequin motif on the bonnet, and the sides are a beautiful metalic green. The problem is that the background of the transfers for the sides of the car are a pretty blue colour (instead of green !)

For those who are interested in the details, the exhaust was on the side that year, it was just in front of the rear right hand side wheel. There was a small aluminium protection just above. Raymond Boutinaud says the car sounded american like that, and he didn’t like it. The inside was very bare, painted a black matt colour, apart from the security frame which was an aluminium colour. The car had its original steering wheel.
The 84' model is faithful. You can recognize it by its scorpion on the bonnet. R. Boutinaud is Scorpio. Did he imitate Carlo Abarth ?

There is also a transkit from which you can make the 1983 tries model. A transkit is a set of pieces which allows you to make a particular model from a standard kit bought elsewhere. This technique was used in the 80’s.
The testing version is different from its race counterpart by the rims which are a different model (RONAL) and because it had less stickers because the sponsors arrived too late. Unfortunately  you still have to use the transfers with a colour problem.

Whatever the version you want to build, you will have to be very patient. All these models are of course out of production, you will have to look for second-hand models.
