Following the first snapped one your dealer should have checked the run of the cable, for two to go so qucikly suggests that the cable is being over streached or is seriously snagging something on full throttle. This was a common issue on the S but I'd have thought TVR would have got it right by now! Rich...

Snap! Pardon the pun... it's great when it happens at speed on a dual-carriageway! It appears to be a problem the way the cable is put under pressure at a stupid angle near the pedal. Thanks to the bloke from Dowleys Recovery of Carterton who made a nice job of temp. fixing, thumbs down to Henley Heritage who wasted most of my day by not having the cable in stock when I turned up having said they had! markgj

My Tuscan RR is cool too. 8500 miles. No problems. That goes for the 400SE and the 500 Griff I had before also!

Can I recommend that you check that the cable inner is not fouled by a slighty overlength bolt that is part of the accelerator linkage in the pedal box. It is only able to catch the cable near 3/4 or full travel.

If this bolt is catching the cable it will explain why you have had it go so often. This may not necassarily be the cause but something is fouling it by the sounds of things.

I had my cable go in France 400 miles from Calais...! At 11,000 miles.
Apparently the cable need to sit properly so that it doesn't get overstretched. Outrageous to have 4 cable go!
I got the Frog AA man to do a temp fix...worked ok whilst limping back to ole blighty..
A real pain though. I was videoing the Tus going down a French Country road, popping and banging with it's new sleeved exhaust..when all of a sudden...snap!!!

I picked up my 96 Griff500 3 months ago.
Nice hot sunny day pootled away from vendors house straight onto dual carriageway, doing about 50 mph, an Audi S2 coupe alongside, thought I'd show off a bit (never gone full throttle in the car before), dropped into 3rd, buried the throttle, ROARRR..SNAP - throttle cable broke and sheepishly crawled along the hard shoulder on tick over with S2 disappearing into distance vigorously shaking semi-clenched right hand over his shoulder...
Had to laugh...

Just had throttle cable go on me. Is it a DIY fit, more to the point do you need to get underneath to feed it through? What happened to the fly by wire technology it had, am I correct in thinking this was removed on one of its 'visits' to blackpool,. I ask all this as I'm in Germany and the part is being sent over, therefore I will be fitting it on my drive.
Any advice gratefully received, constructive advice even better.

The cable is reasonably easy to fit and can be done on drive. Remove pedal box cover (allen screws) and you will see the linkage to the accelerator. Follow the existing cable run when you put the new one in.

As a tempary fix you can reline the existing cable with a thinner cable fix kit which will get you on the road.

Only thing to consider is that the cable isn't trapped when you put the pedal box cover back on. Wrapping the cable in some foam where it catches the pedal box cover will also reduce the ticking noise that can sometimes happen.

How does the throttle cable snap? Is it a cause of agressive acceleration? Or a known fault in the design?

It is down to poor alignement and tensioning which causes the cable to bend and so break eventually - TVR sent a note to all dealers a while back (months ago) about it and they should check the cable during the servicing to make sure it is set up correctly and so avoid it snapping
