If it was either Ashley or Fern driving it, they're both extremely quick in karts. Unlike me.....[

I was very impressed with the way the bullet cam dealt with that (assuming it wasn't just moving about on its mounting). Does it have some form of image stabilisation system.
I enjoyed the video more when I turned the sound down and made heel'n'toe vrooming noises [

Yes, I will be there. I hope to have my car back on the road by then - hopefully with an engine that is in tolerence and working fine and well.
However, I am concerned at the cost of a day at Castle Coombe, how much will it cost you? I am super interested to know.
Also, given that Castle Coombe is some 100 miles from MK, you might need at least 8 gallons (36 litres) over what you use on the track. You won't run out on the way then.
Also, will you be using a set of slicks, as I believe you did at the weekend at Bedford, I might do the same but need to know what it is going to cost? Do you know?
It is so expensive this motor racing lark. Isn't it? One wonders how it doesn't bankrupt.

This is a good point! Has anyone worked out a cost for trackdays in a 944? Inclusive of the fees, fuel and oil, tyres etc.? It's something I get asked occasionally but as I've not done it I can't really answer.
I've always assumed that it was an expensive hobby - and as I don't have the £3k or so in the bank to replace the car I've not risked VJ on a track so far! Racing someone else's karts seems a more risk-free way of getting the thrills.
As a ballpark (because you need to know variables like the cost of the day, distance to travel and the type of tyres and brake pads etc. in use) you're looking at roughly £500 per day provided nothing goes wrong to include tyre wear, brake wear, fuel, entry fee and additional servicing.

Ouch - I only pay about £60 for an evening's karting.....
Well, they do say you need deep pockets to be involved in motorsport.....

I am sooo impressed with the Vitesse Piggyback system [8D]
This afternoon I spent less than an hour tuning LIL myself and in just this short a space in time I've managed to dial in the following WOT fuel ratio:
I sent a copy of the Wideband plot and also the piggyback logfile to John at Vitesse and within an hour he has already sent me back two alternative maps that he believes will get me even closer to a flat 11.8:1 fuel ratio. To be honest I am gobsmacked that 'so far' it has been this easy [&:]
Even the rough fueling that I dialled in myself has noticeably increased the power and I am still running at the 13psi left over from Bedford. Once the curve is perfect I'll be turning it up []

Wow, £500. Mind you, given that these are expensive toys that need expensive facilities to play with them, it doesn't seem alot... unless of course you can't afford it, or worse, owe seven times that amout to someone else.
Anyway, thanks for the valuable information which is duly filed in my little red folder!

For the Bedford day for example I'd say:
Cost of entry £140
1/3 wear on a set of tyres at £500: £166
1/3 wear on a set of disks/pads at £360: £120
Fuel for session plus travel: £100
General wear and tear on car (oil etc.): £50
That's about £575
Being caught out spending that sort of money on playing when you claim you don't have any: priceless []

I don't think you're far out Fen, but I'd hope to get lots more wear out of tyres & pads - maybe twice your suggestion, and disks especially!
I hope my new P zero C's last longer than 3 track days anyway - I'm using them partly because I reckoned they would last longer than the T1-R's.
I can easily go through a tank & a half on a full day though - and that's without travel to & from the circuit.
To my mind, after fuel, general wear & tear is probably the biggest cost - and the hidden one. Cars take a lot of hammer on track days.

That's fuel!
You might be right Ed. It surprised me how quickly it mounted up and I was possibly a bit light on fuel. I know I did more than £100 worth last time plus travel. I might also have been pessimistic on tyres and discs, but I really don't think by as much as 50%. That's swayed hugely by the circuit and driving style though so you may get 6 days on a given circuit and I may only get 3 on another from the same components.

I can't say I'm the most sympathetic on tyres & brakes - but I reckon at Donington for example (which is pretty hard on brakes) I'd double your figures for tyres & hope to get 10 trackdays on a set of front discs. I don't like to run pads too low - the pedal feels much better in a 944 with plenty of meat left on the pads. Rears should last 6 or more though.
I'm there on Sunday (Crashzone [] ) with Ross in Ben's old turbo - If it's dry I'll give the P Zeros a try
we've bit OT now - sorry Paul

No worries, it's an interesting side issue. Personally my rear track tyres have now lasted at least 20 trackdays and I have found that the fronts used to last me 6 days and only needed changing due to wear on the outside edge due to my road settings. A more extreme camber should make them last a bit longer. I had new Michelin PSC's on Saturday and they seem to be down from 4mm to 3mm after one day so I think they must be softer than the old Pirelli Hard compound Slicks I used to use.
I always use OEM pads and the fronts last 4 days, the disks about 8 days. The rears last so long its difficult to gauge. As for fuel I used a full 16 gallon tank on Saturday to cover 140 track miles, which is about par for the course.
It's certainly an expensive hobby [8|]
