HTP for 1965 TVR Grantura MK111 1800S

[ixxifan]

Hello all
I'm hoping you knowledgeable people can help. I've arranged to look at a 'barn find' 1965 TVR Grantura mk111 1800S. I'd like to buy it to rebuild as a race car and wondered it it's eligible for HTP papers? It has a chassis number starting with 65/5/****. I've had some conflicting views about gaining an HTP for it and wanted to know before I make the seller an offer. Any/all advice much appreciated.
Thanks
Steve

Papers should not pose any problem at all,as long as it is 65 and no later.Is this the Yellow one thats been on the market for quite some time?
Be very carefull with these car's,if the body is still bonded to the chassis,you could well be faced with a new chassis project,the chassis are easily available from David Gerrald.Bodys[new ]are also available.Both body and chassis are not badly priced ,I would be budgeting 30/35k for a competitive car,time the mechanicals are brought up to spec,good luck with it,they are a lot of fun to drive with 180BHP on tap from an ally headed engine.

Thanks for the advice Terence. Its not the yellow one. The one I'm going to look at is a C reg red car apparently the original owner couldn't pay a bill to a mechanic who'd done some work it so he left it. The mechanic has had it in a barn for 25 years. It seems complete but of course it'll need a full restoration. I'm going to look at it on Wednesday next week.

The good news is that you have a precedent in that Mark Ashworth races an 1800S in FIA events, although to my knowledge this model was never raced in international events in period; there was some disquiet when Mark got papers for his. I'd speak to an FIA scrutineer like Jim Lowry or John Hopwood just to make sure, before committing myself.

I agree with Terry about cost; should you have the money I see Roy Stephenson's ex works car which is quite competitive is Racecarsdirect.com for £40k

Good luck

See-ing as Mark now has his HTPs,there should be no reason for them not to be granted,so go ahead with you're project and good luck.

Make sure it has a round tube frame and triumph front suspension (spitfire/herald uprights like a formula ford)

[Jeremy Hall]

All this plus homologation on number 160 at ....wait for it ....600 kgs.I can here Terry weeping from here

[terence]

Why?.it's only 15 lighter than the "B".

[ixxifan]

Thanks for the tip Esper, I'll make sure it has. I've only seen poor quality external photographs so far so I'm looking forward to viewing it for real.

Is it really possible to get it down to 600kgs?

Awr YES!. No helium or Marcos type builds either.

[zefarelly]

new single layer shells and T45 chassis I presume ?

my old Vixen was about 750 with a half cage in it, it had genuine TVR doors and bonnet though

[Jeremy Hall]

Appendix J had a schedule posted in it which dictated the minimum weight for GTS cars. THe schedule was based on the engine size-bigger engines equalled greater weight. So if you were a smart manufacturer you went to the schedule checked the minimum wieght for the engine size and bingo homologated weight.
Thus 1800 cc equals 600 Kgs. TVR and Marcos both have 1800 cc engines.
Simple if you know (knew) how

[jonners]

I know this is off topic but.....

...be careful when raising eyebrows about Marcos weights

My Dad bought a wooden one new in the sixties and sprinted it for years. With a pre crossflow Ford engine he weighed it at less than 450 kgs on a properly clibrated weighbridge

When he sold it back to Jem Marsh (who raced it for several years) Jem said it was considerably overweight...

People seem to find it hard to believe...

I used to sit in it making brum brum noises when I was ittle - knowing what I know now I wouldn't even sit in it....

So BMC really cocked up with the "B" then, ---t!!

The chassis is cds tubing,the body is three layer glass,dont forget that more is known about resins etc these days.Plus of course the Vixen has a bit more length=weight

[zefarelly]

the vixen was actually reasonably solid!

I know what your saying Johnners, the same can be said about my Rochdale, it'll probably be 700 kg with a cage and some reinforcements, as well as its original 'heavy duty' build spec, apparently the 'lightweight' was 450kg or thereabouts, obviously it was lethally thin

I do remember Yves Courage having his carbon fiber sheets in a secure locker in the eighties. lucky you , its cheap these days as any punter uses it in a dragged Astra. 500kgs piece of cake!!!!!!!!! (means a cheap budget on brake pads)

Dont you start as well Esper. Besides,you have one of thier engines in the Grantura.

Slightly off at a tangent - how do you find if it is possible to obtain HTP papers for a car, for example early Lotus Sevens - and how do you find which events you can then enter? P.M.'s if you feel it is off topic. Thanks.
