Oh dear, Graham... it seems you've fitted wonderful new wheels, a fuel tank up front, spax suspension, carbon fibre panels, carbon fibre roof!!, roll cage... What's happening with the engine??

I've got chills...  Tongue

Hi Anders,

Err the engine...now thats a very good question???

As you can see from the picture there is a very large space in the back now for pretty much anything I like really.
I am not sure which way to go at the moment as I have a good Murena 2.2 engine complete more or less ready to drop in. It would then be eligible for Prescott Hillclimb and similar events, or to move into the dumping ground of specialized class where anything goes and also have myself a very interesting trackday car. Having seen the Honda Civic conversion in the UK, I must admit that this is probably the way I am leaning towards at the moment. It will not though ever be road legal and will have to be trailered to events.

There is still lots of work to do as it more of a running mock up at present. The previous owner in Germany basically had to give up on it, as it was draining his time and resources whilst still trying to run a business.

First thing though is to sort out the rear trailing arms, as I was rather hoping I can convince someone ( i.e. my new best mate) to put me first on his list for a pair of fully adjustable for camber and toe in trailing arms, he has a design for in his mind.

Cheers,

Graham

P.S. There is also a little bit more carbon fibre on the car, look at the dash! Shocked

Now, so this is not the eBay advertised Merana... I begin to understand Wink
I love it Graham. I really love it! Smiley

That space in the back is very roomy indeed Cheesy

I love the big Murena 2.2 lump, the sound, the way it looks, the noise it makes, vibrations... everything! At it does have a race heritage, it was even used in Le Mans in the 60's (not in a Matra though).

But it's just not suitable for racing any more unless you have a load of money to spend keeping it running. Spares are too rare and expensive Sad A Gordini engine is cheaper to work on! And if you race - you RACE. You don't want to be careful with the car.

So I understand your focus on alternatives. I think i'll approve it, even if you fit the Honda engine, though a Peugeot would make a lot more sense IMO.

About trailing arms - BMW used to have that on their race and rally cars. It's feasible! But if I was you, I'd begin with considering adjustable anti roll bars. The roll bars are THE balance tuning item on any car.

Someone recently crashed and burned a Ferrari 430 in Denmark, with a potential buyer at the wheel. Sadly both owner and buyer got killed.  Sad

Wonder if the V12 engine survived and could be bought from the insurance company. Looks like it would fit. Grin

The space at the back is almost all behind the rear wheel line a consequently most center engines will not fit into the space (defenitly not a v12 Ferrari). However a Renault Alpine V6 is hanging out at the back. 185 -200 HP seams to standard output. But with 2.5 L displacement and turbo more power will be available at wish.

I do not think that anything hanging out to the rear of the back wheel centreline would be a great idea, unless you want to find out the extremes of understeer and oversteer that is!

505kg. at present.

Componets required:
Battery which is mounted under the right scuttle where the fan used to be.
4 x brake calipers
Engine
Gearbox assembly/ controls.
Front nose cone
Rear wings
Rear bumber assembly

Any ideas of the weight of that lot. 250kg. perhaps depending on power unit??

Currently weight % distribution is:
55% Front / 44.4% Rear
Right side 48.87% / Left side 51%

See attached images for clarity

NB: Not on a particulary level surface and with flatish tyres, but looking pretty good anyway as a starting point. There are coil overs dampers with adjustable spring platforms for all corners, so corner weight jacking will be achievable.

So the million dollar question (and probably cost!) still is which way to go with the power plant?Huh?

Cheers,

GP

I just saw, and heard, njesper's Murena with the AlfaRomeo V6. Man, does it sound sweet. The best part is that he has got the Danish paperwork through, so it is fully legal in Denmark. That should clear the way for others who want the appx. 184 HP this puts out. Grin

with 345 HP you will need to reinforce the frame of the Murena.

I think that the best will be the 0,8 CDi engine from Smart  Grin

Still considering all the options? Whatever is fitted though has to have a certain "ring" to it and look good on the badging on the rear!

Matra - Honda
Matra - Peugeot
Matra - Renault
Matra - Alfa
Matra - Smart
Matra - Ford Cosworth .............Ooh now that sounds familiar?

Which brings me to a Ford Cosworth YB 2.0 16v Turbo. I would not go down the turbo route, as I would want to keep things as simple as possible. A popular conversion is to fit twin 45/48 DCOE Webbers, lower the compression ratio and 225bhp is easily obtained.

There is a wealth of knowledge, specialists and suppliers locally to me, in particular Burton Power Products, who can provide all the parts for turning the engine around for a rear wheel drive/kit car type installation.

http://www.burtonpower.com

As an aside their Tech Tip section is very good.

I think I will make a few enquiries.  Undecided
