Bill moffat started this topic some 10 years ago and I've just stumbled accross it!!
It is true that F100 in its original form must have been terrible to watch-too underpowered and with road tyres!! I did have a programme that a child had written in to the same effect.
Once the sponsorship from Firestone and Tarmac finished, the cars slowly disappeared. Having seen Mark Coles articles in 'Hot Car' in period I was asstounded to find that in 1988 I had purchased the very car featured, albit in a thousand pieces! It was one of the 3 Sturdgess's produced for the original Championship. These cars were built by Elden.
The HSCC were running 'The 2 Litre Sports Car Championship' at that time, mainly for Chevron B8's, but with classes for 1600cc and 1300cc engined cars. Due to the fact that F100's ran at 3 International metting, the HSCC agreed to allow them into the Championsip. In 1990 I had rebuilt the car and at the time other F100 cars were running on a regular basis.
My first race I encountered another Sturdgess, a Landar, an Aldon and at least one Royal, there were two Nerus's about too. Another Royal joined the races at a later race which had been converterd from a road car-chassis no.11 with a number plate 'MAD'!!
We were allowed to use tuned 1300 engines with racing tries. These modifications transformed the cars and they became very competitive. This should have been standard in 1970!!
I know were some of the cars are now, but very few are racing as there is no class for them.
I had 19 fantasic years of ownership, masses of fun and made loads of friends.
If anyone wants anymore info, I will be happy to provide. Unfortunately all my records of the original F100 races were passed on to the new owner of my car--may have some still stacked away somewhere!
Cheers
