Post subject:  2CV in Production Car Trials?
Has anyone ever used a 2CV or any of the variants for Production Car Trials (PCT)? Having driven 2CV's in the past and recently started to participate in PCT's the standard car would seem to be eminently suitable for this with the combination of light weight, long suspension travel and good low down torque/low gearing. Comments and ideas appreciated.

No, but ... you were asking about this on the phone the other day. I still think it'd be a great car for autotesting, but you'd need a rear wheel handbrake. Fortunately, Russ was looking into this not too long ago ... viewtopic.php?f=7&t=4696&hilit=rear+wheel+handbrake

Looks quite easy, especially with the Demon Tweeks hydraulic handbrake in the link below:-

I'll probably be looking for a road legal or easily restorable 2CV or Dyane over the winter once I have room in the garage. It would not matter if it was a bit scruffy. Anyone want a very nice 1931 Morris Minor open tourer........? See pic attached (sorry its not a 2CV)

A Mehari would probably be good for PCT's!

The hydraulic hand brake would need seals suitable for LMH brake fluid as they would be affected by it's use. I would guess using a 2cv master cylinder and a hand brake made up to operate it would work fine. :idea:

Can't even use a handbraked rear caliper off any other LHM Cit, since all LHM cars used front handbrakes. Hmmm...

Could use a 2cv or G front caliper, either with a serious pressure reducer in the line or just additional to the actual footbrake caliper?

The 4x4s use BX-etc rear calipers on machined down discs, mounted inboard.

I think a 2cv or Mehari (even worse) is not suitable, when braking 1 rear wheel of a 2cv/Mehari nothing happens at all. Your just sliding 1 wheel over the tarmac and thats it. It doesn't turn any smaller with this device.....

Only on speed making a handbreak turn would help, but I guess in a cartrail (as I understand it) you can't make enough speed in a 2cv.......


Ps. the weight on a rearwheel in a lightend 2cv/Mehari (get the rearbench out and spearwheel thats about it) will be around 80kg so this is 2 times nothing....

The rear handbrake would not be necessary for most Production Car Trials which are held on grass or other off road surfaces. The PCT's are all about maintaining grip and momentum and getting as far as possible up a steep slippery slope within the limits dictated by the section marker posts.

It would be useful for Autotests which are timed and feature sections with very tight turns and sections where the car has to be reversed. These are often held on grass surfaces nowadays as tarmac venues are more difficult to find. It would be necessary for any modification to ensure that both rear wheels are braked, one wheel braking would be pretty much useless. The rear brake would be used for flicking the car quickly through 180 deg or for tightening a turn round a single cone. Any autotest held on a grass surface does not need huge power, just great maneuverability and good traction.

Sounds like reversing a Mehari at speed would be like trying to throw a hammer, shaft first......!

I think your far better of with a quaife limited difflock from Mister Barbour then.... if it is allowed...????

http://www.barbour4x4.com/limitedslipdiff.html

but the "handbrake" on both rearwheels will be needed also I guess....

and you need an extra lowered 1. 2. and 3. gear too..... or simply an 2cv4 gearbox....


If I would do it it would be like this....

an old pre '70 2cv or better an pre '60.....

710cc engine (www.VGS2cv.be)
2cv4 gearbox with disks
Quaife limited diff
roof down to bumper ( no bootlid to heavy) with big rear window for view.
al (rear) windows out of aqryl
as said befor, rearbench out spare wheel out.
Only 1 seat infront.
Small motorcycle battery......
drill a lot of holes to lighten everything.......

and have fun...
