Of course I did. With plenty of other modification. But knowing that, why am I developping 16V heads on Simca engines ?
This is a quiz  1. It failed? 2. It did not produce enough power? 3. You got bored and needed two new projects? 3. You tell me!  I took a look at Cat Cams' catalogue. Intersting stuff. They have a 331 degrees cam for the engine. That sounds like a wonderful starting point for a ridiculous race engine! I don't dare guessing on the max power, but it will probably take very special components to make it run perfectly.
Not that exotic. It seems that until the 1440 cc engine, they are quite bulletproof [/quote] Interesting... were they ever homologated for a race/rally car? /Anders

Hi Philip Congratulation on your Matra. A couple of years ago, your car, and its owner was a member of Matra Club Denmark. Like Hans, I have seen your car many times, but what I remember most is, that the owner who made it look like it does today, spend the most of his time working on the car, and hardly never drove it. He was always afraid it would break down around the next corner!...  .. Like Hans, I remember it to be a pretty decent example of the Serie 2 Bagheeras, whether you like the modifications or not. I hope that you will get a little more fun out of it, even though you´re not satisfied with its engine. I Also hope that we will get the car..and of course you, back in the Matra Club. Lars Tjørnelund

Hi As far as I remember the previous owner of you Bagheera changed the whole driveplant due to problems with the gearbox, but he was also very keen to get some extra horse power. (However he was not satisfiyed with the increase in power). The engine in your Bagheera is the 90 HP version of the Solara engine (there is also a 70 HP version).
Spyros: I was very much in doubt if it was the bore or the stroke that has been increased. From the 1300 cc to the 1442 engine the stroke is increased and from the 1422 to the 1.6 the bore has been increased, or is the other way around. (Siting in Vladikavkaz I had no chanses of checking my documentation)
Getting extra horse power: traditional tuning, turbo, compressor and/or NOx. Depending on your wishes, skills and money available. Please have in mind that adding a turbo or a compressor will be considered at adding more than 20% by the Danish authorities, and you will there fore have some additional trouble and paperwork to do.
To become a member of the Dansih Matra Club you simply send a PM to Bagheera_Lars who has been our chairman for more that 10 years.
Hans

Hi Hans, On this type of engine, 3 strokes have been used : 65, 70, and 78. I list the 65 stroke due to it's usage on small engines but also due to the reving capacity  The 1290 and 1442 shares the same bore (76,7) and differs by the stroke (70 versus 78) The 1442 and 1590 have the same stroke (78) but the 1590 has equidistant bores of 80,6 The 1442 has the cylinder pairs 1-2 and 3-4 more appart. Interestingly, some are telling me that you can just rebore a non equidistant bloc to 80.6 I'm not sure it will allways work since in between the pair 2-3, there is a water conduct. If successfull, starting with a 1442 engine, you'll get the 1590, without the supposed high rev flexing of the crank. But starting with a 1290, you get a more free reving engine (I have a 1290 Bagheera and it's a joy) and a 1430 cc engine (even a ... 1442 with the first repair size)
