Why stupid? Its about a level playing field and about trying to minimise the amount of expensive parts involved.

Err, yes - they'll strip the head if need be.

Lol, yes. They would check.
Regs are there to be observed not blatantly ignored.
Who would want to win knowing they had done it illegally?
The essence of the Locost series is that it is pretty much down to driver skill, and certainly not budget, and people operating outside the regs soon
find the paddock a rather lonely place to be.

Im not saying cheat, what im saying is that its supid that you can use off-set dowels as apposed to varniers.

Hi
There is only 2 real choices with the valve timing. Your either going for bottom/mid range grunt or a higher revving top end setup. Use a decent
manifold to suit the chosen setup and your sorted once you have the correct jetting to suit. The only thing to note is that due to Kent cams having a
"tolerance" in their machining you cant take it for granted that there recommended figures are correct. Take multiple readings on all 4
cylinders.
As mentioned the Locost championship is one off the closest matched formulas in the UK. And as proved again this year those who take the wee with the
regulations are caught. And again for 2012 the regulations are being further tightened to ensure equal performance.
Cheers Matt

Seems daft, as the rolling road time is the largest expense, so if I was of a mind, Id be fitting a vernier, running it on the rollers to find the
ideal timing, then getting the correct offset dowel to replicate that timing without the vernier. Thus the allowance of timing adjustment means Ive
either purchased two parts, or wasted rolling road time swapping dowels in and out.
I'm all for the championship but that one doesnt make sense to me!

Well yes that's obviously what people do  A lot of the rules were devised with 'low cost' in mind - most of the really silly ones
(like not being allowed to use a 2000E gearbox BUT you could spend 4 times the price of a 2000E box getting a Type 9 with the same 'standard
Ford' ratios built up) have gone but there's still a couple that don't appear to make much sense. Rules is rules though and over the
years there have been numerous........ how shall we put it.......... cheating b*stards.......... so they are there and enforced for very good reasons

I take it that a knock sensor in the electronic ignition box is a no no.

No, as I recall several people used to hide that sort of thing in their 'datalogging' boxes instead........

On the subject of being acceptable, to digress a little, I had an interesting conversation with Keith Messer regarding alternative front lower ball
joints. Procomp Matt was stood by as well, listening intently.
Keith's reply to what I was proposing, was that 'it should be able to be made by a carpenter on his keitchen table, with normal workshop
tools.' He implied I was a professional, which I am, but i don't earn my living just building cars. So I'm not a professional car
builder.
Depending on how good a carpenter a man is, and what you define as 'normal workshop tools', the options would seem, for a man like me, to
be fairly wide spread.
Cheers,
Nev.
