oooooooooooooooooooh, just seen your mobile, veeeeeerrrrrrrrry cool
the only important technique to drag racing (in my opinion) is not to break anything otherwise your RWYB becomes a LWH (long walk home...)
The start line area is so well rubbered there is perhaps too much grip for transmissions which have not been prepared specifically for drag racing, ie
I can imagine that if one were to dial in 5K and dump the clutch bigtime the gearbox (if a vitesse/gt6 one) or the rotoflex joints if roto could give
up.
Not the fastest way, but perhaps the most preserving way is to treat the clutch to some abuse and use it as a torque convertor, keeping the revs up and
progressively feeding the clutch in until the road speed matches the engine speed at say 4000rpm then running the last thousand or two before FIRMLY
going for second and then third ( a missed gear will loose far more than a deliberate but succesful change).
unless you have a gt6 box on a 327 diff, perhaps shortshift into 2nd and drive it through on 2nd and 3rd - I have a big saloon gerabox with a low 1st
gear and lowish 2nd so there's no point in hanging on in 1st gear as it's over very quickly anyway.
I did 17.something seconds with a terminal of 85mph or so which is nothing very spectacular, although the weight of my green car is 950kg without me in
it (ie about the same weight as a standard GT6) The rollcage was not built for lightness.
The search for acceleration is very seductive, and i can see that it can get very expensive, very quickly with bits breaking and needing uprated
replacements especially in the transmission and backaxle area
enjoy the day, but preserve the transmission... and give Vicky a good spanking from me as well!

Cheers Jonathan,
I was figuring that I should ride the clutch on take-off at around 4Kas you suggest and short shift into second (always a bugger) then just floor
it. I intend on using a rev limit of 7K (she does more) and o/d 3rd instead of top (3.89 diff. I'm a 2 liter, so if i'm in the 17's I guess I'm OK.
Should sound OK though 'cos the 2" exhaust I made sounds awesome and I'll have the filters off the Webers with the 2" rams open and when she comes
on cam it howls!
Thanks for the advice, I'll let you know how I get on, see you at Stafford?
Anyone else at the Retro Car show please come over and give some support or alternatively take the p*ss!

Thanks Jonathan,
I too would have been at the "other Gig" if it wasn't for redundancy! Still there is always 2008, which is my ultimate objective (in
between I hope to do the TR Register Hillclimb championship) including doing the laps. That would at least give me the opportunity to spend
my dotage in the pub claiming to have pulled 7K revs in o/d top on the Mulsanne whatever really happened!

hmmmmm
let me know of your progress with hillclimbing, ie prep and licence and stuff. I still haven't been able to afford to race the green
car and don't expect to be able to do so, but if you are going to hillclimb next year I might be able to pursuade the important
people...

Consider it done. The great thing about hillclimb is it is relatively cheap motorsport. About £70 entry for a round.
The licence requirement is National B Non race (about £30). I hope to get one or two in this year if I can get a job.
I promised NiG on this forum, that I would write up my exploits (not a bad idea 'cos it doesn't get much coverage even though a GT6
won the Revington TR series last year) so I best get on with it! Though it might turn into a "how to go motor racing with no money
and a hole in the arse of your trousers" or "honey I sold the kids but I got a race car"! My mentor is Perry McCarthy and his book
"Flat Out, Flat Broke". Read it.

I agree Perry Mcarthy's book is a good entertaining read. I won a signed copy in a raffle earlier in the year and it graced our
smallest room downstairs as my reading matter for quite some time, made a change from the latest version of the Courier which
is what I normally read when I'm in the think tank.......
