Vixen- Factory engine/competition options?

[XavierS2]

I am researching the viability of racing a Vixen here in France (non FIA).

Local technical regulations state that period engine modifications and or competition options offered by the manufacturer are permitted.

I was wondering if TVR ever offered any such engine options or upgraded parts and if so does any documented proof exist i.e. sales brochures etc?

None that I know of, but it is a really good subject that brings up lots of wish lists.

The factory produced a couple of Vixens with Lotus Twin-cam engines. Also I believe there is a Vixen in Australia that was dealer fitted from new with a super charger. I think this was a dealer fit option offered by the factory at some stage. I'm sure other more 'knowledgables' will either contradict this or fill in the gaps.

Steve, a while back I bought (and since sold) a Vixen with a twin cam in it and Brian the owner (who was quite friendly with Stan in spares, he was also owner the ex PW turbo and a Grantura 2A at the time, along with being a priest, so I believe him!) even with the help of his his leader (sic) he could not prove that the factory ever put a twin cam in a TVR of that era.

In the November 1970 issue of Customer Car magazine, they test drove a factory owned Vixen with a Twin Cam fitted. They state this was the development car for a planned BDA engined S3. Whether it was ever sold with that engine fitted ..... well that's another question!

[Adrian@]

From memory of speaking to Brian, that was a customer car that the factory got 'attached' to (I let the car go because I could not prove that the car was a production item) and I tried my hardest to align it with the factory, without any luck, other wise I would still be the owner. I know Brian was able buy a replacement exhaust manifold via Stan in spares (as I saw/had the hand written factory invoice), but Stan was always able to supply the part required when it was needed.

That's a shame. It would have been nice to drop a twin cam in and retain a historic originality. Any knowledge of the S/C option? For the OP that would be a more interesting route possibly.

If you read the info on this car then this well may have been originally fitted with a twin cam engine from new. It would be nice to know if the owner actually found this out from the DVLA. It is a very early S2 Vixen.

OMG, a Vixen with a Lotus Twincam or BDA. Now that would be a formidable factory combination.

In fact, think I saw a brown Vixen or M at the last Chatsworth with a Lotus Twincam installed.

BDA=

Barnet cars ?

That is all I could get..nothing that came out as a fact 'made in Blackpool' and 'a may have' was not good enough to keep the car.
There are enough with them in.

They were Speedwell tuning parts and I am fairly sure I have a factory Vixen S2 price list offering them as an option.

[Adrian@]

They were not in "Sprint" or "Super Sprint". They were called Sprint and Supersprint depending on state of tune. Sprint had modded cam , head and few other bits. Super Sprint had the above but with twin 40 DCOEs and some othe minor mods.

Ah said the blind man...
