Re: Thunderbolt !
I was going to say if you're a BDC member you can NOT NOT be aware of Thunderbolt or Graham Moss and his record braking attempts.
There's also David Llewellyn's Napier Bentley which has it's own wiki page http://en.wikipedia.org/wiki/Napier-Bentley
Chris Williams another BDC member also built the 1,500 bhp Packard Bentley
And of course the famous Napier Railton at Brooklands....
