triumph 1300 4wd

[feddes]

So about two years ago i saw something online about the rally works triumph 1300. This is a triumph 1300fwd converted to 4wd using the pony gearbox. And i thought well this is something I would want to build so this summer I impulsively bought a pony gearbox. Now I'm wondering if anyone has more information on this special car...

I've read some about it in The Works Triumphs book by Graham Robson. All I remember was that it had a Le Mans spec engine and 2000 derived rear suspension.
I will have a look through the book shelf to see if I can find out any more.
I got hold of some really interesting pictures of the Le Mans Spitfires from Gaydon Motor Museum but things have change there since and I don't know if they still have the archive there.
Canley Classics had some gearboxes and there was some info on their website.

Thanks I've indeed bought the gearbox from Canley classics. They've tried to build one as well but it couldn't go over 35 mph i believe. But i'm also still looking for a 1300 or 1500 fwd to convert but they are very rare in the Netherlands or cost a fortune.

I wonder if the Pony spec box had different gearing ?
I had a quick read and it sounds like it was quite good but only did a few events before the rear suspension broke. The accident wrote it off.

If i remember correctly the final drive of the pony box is 3.9 or 4.2 and the tr4 had a final drive of 4.1 so on lose ground that difference wasn't to bad. but once you shift in to 4wd mode the gearbox goes into low gearing and that needs to be disabled

I found a picture of what is said to be the car in another book baring the reg number LVC 151F.

that's a cross section that could be very use full hopefully i can figure out how to remove the low gearing part of it.

If you are FB friendly then look up the Triumph 1300 group a chap named Nathan Biling will tell you all you need to know, in short the AWD used Triumph 2000 rear set up but because the front to rear ratio is not the same and it is a fixed drive you wouldn't be able to use it on the road as the front wheels turn quicker than the rear and that's why they were selling the boxes cheaply.
As for Canley Classics actually building a pony boxed 1300 has ever seen any pics of it.

You may be able to offset the drive ratio difference front\rear with some slight manipulation of the tyre diameter\profile, you're only looking at about 5% so if you get the shorter ratio drive on the back going 10mm wider on the rear at the same profile as front may correct it.

I will try to contact Nathan and the bigger rear wheels could indeed be a solution. Will look into that as well.
Ps if anybody knows some one in the south east of England or preferably the main land with a 1300 for cheap I might be interested.

And the it's luckly not a fixed 4wd box there's a selector on it so you could drive it on the normal road in "fwd mode"

[steveg]

I was wondering about an overdrive unit but that would gear things the wrong way I think. You couldn't run a normal Triumph one backwards but could you create an underdrive with a mechanically selectable overdrive like those used on Land Rovers.
My 4x4 Transit had mis-matched axle ratios. You could only use it off road to avoid the transfer box getting wound up. I never really thought about it but in use it would mean that one of the axles would have been doing more work so as long as things worked the right way it would probably be a good thing. Modern 4x4 set up have a front to rear bias so perhaps that is what made it so good.
I would be tempted to use a car with a RWD shell and keep the solid axle and then fit the FWD subframe, it wouldn't be a very good replica then though.

Finally i can post an update, it looks like I've found a suitable triumph 1300fwd to finally be able to realise this project! The pony gearbox has been collecting dust for the past 4 years so that has a use aswel now haha
