What are you trying to achieve with this list? Are you trying to turn your Murena into a race car?
Well Jon, personally my needs and wants are not essential for this thread.
Weight reduction has always been an easy source of gaining power, and having an old sportscar, that by, some people is regarded as lacking power (well I think that even Matra mentioned it themselves one time), this thread could end up creating a good overview for enthusiasts, wanting to reduce weight, to gain power, without getting in serious trouble with for instance, legislation.
Whether or not you wanna have a stripped down sportscar, or you wanna loose some pounds, by for instance replacing with lighter parts, that could still make the car look great/original, I found this idea a good one. Loosing weight, does not necessarily mean "race car".
****************
Danish legislation
for example, has some very tight rules, for people wanting to up the bhp of their cars.
Rule of thumb: 20% increase is allowed, but can still create problems, every time going to the mot, you still need papers on the upgrades from the manufacturers, especially if the parts mean changing "the construction" of the driving abilities of the car.
Between 20% and 40%, means going to an approved by the government test laboratory (costly), for getting tests and papers done.
And beyond 40% effect increase, FORGET ABOUT IT!
(if you wanna do it the legal way).
Because then you have to take the 2000km test, meaning the car is driven for 2000km (at a test track i guess, making the risk of having a 25 year old car breaking down at least 10 times during that), then disassembled totally, and each part analyzed for fatique.
Ehhhh... how do you do that with an old sportscar with already worn parts??? you don't I guess... not to mention costs, of both the tests, analysis, documenation, and all the delays, re-testing for everytime your car throws a leak etc.
you do the math..
This test, I guess, is only for the car manufacturers, kleeman tuner companies etc, or veeery wealthy people, who are very bored, combined with a seriously scary patience.
thereby, this thread re-explained - now in details
