Title: Supercharge your Matra-Simca
Post by: andyowl on July 23, 2009, 08:48:13 am
We are just starting a new subject in the Bagheera section on "Supercharging your Matra-Simca". This is specifically about the Series 2 1442cc Bagheera but may also be of interest to owners of Series 1 Bagheeras, the Murena 1.6 and Ranchos.

Please join us there!

Hi Andy.

It looks nice and an interesting idea for the Murena. I am not sure it will fit. On the Murena the water pump and alternator are on the right, very close to the chassis. If it has to be driven by a belt, you would probably have to place it in the boot and cut holes into the engine compartment. Perhaps an electric powered compressor could work.

Thats the performance gain?

Only time will tell! 50% gain is the figure usually quoted.

I plan to do some "before and after" rolling road tests not least to set up the mixture at full throttle.

Weak mixture and/or pre-ignition = holes in the pistons

If anyone knows of a SE England rolling road company who is not married to Weber (and understands SU carbs) I'd be very pleased to hear from you!

I have only the smallest familiarity with the Murena having once helped an owner tune the single carb but I had assumed that the engine configuration was very similar to the Bagheera version. I do not know at this stage whether the arrangement I am proposing can be fitted in the Murena. I will take pictures as we go along. Watch this space.

If anyone is in my area (UK, M25 Junction 9) with a 1.6 Murena I would be glad to offer up the blower and see whether it can be fitted.
