...well it was a lovely day today. Apologies to anyone on here who I might have inconwenienced with a couple of stops today!
Anyway in short, it was a great day. Chugga-chugga is a thing of the past thanks to Lanan. Today was the day of the failing fuel pump. We had two give up the ghost today. However despite this I got in some good laps in the morning to get settled and we tuned a few geo settings.
After lunch I got about 10 or so quicker laps strung together before pump failure #2 set in. End result was a 1:15.4 which I am quite pleased about. Also it was just awesome fun. The clubsport is such a great car, goes like a very fast thing and holds on in the corners like crazy.
So sorry to all you experienced racer-types for the newbie-like excitement, but after a couple of dismal test days, today was great despite missing one session completely and having to be recovered in each of the other three!

PS just realised I haven't got much time to learn Oulton...never driven there before!

Do you run a twin pump setup? This may alleviate your problems if you are finding the pumps are problematical. You could either run both together and have permanent
redundancy built into the fuel delivery system, or run a dash switched system, or to be very trick, get your ECU to switch from pump 1 to pump 2 when the fuel pressure drops below a preset level?
1.15.... With slicks and downforce surely you can get more out of it than that. I can do a high 1.12s on my bike!
Great to hear (other than the pump/s).
IMHO that's a very respectable time indeed for someone in a Clubbie getting their eye (and that leg) back in.
Comparison with bike times is at best misleading, totally depends on the track. Snett's two long straights and relatively few number of corners really favour a bike's way way faster pick-up between 100 and 150mph and beyond, that even a Radical's enormously quicker pace through Riches etc cannot make good. As I say, depends on the track: Recollect one of Jon W's qualifying times (pole) at Dony in the tuned PR6 was quicker than Rossi's Moto GP equivalent a couple of weeks prior or after. As far as two wheels are concerned, they don't come any consumately quicker than Vale on his Yam.

We were discussing a twin pump setup to give redundancy yesterday, so may go that route. Having said that, the prev pump was fine for the last few years. The "spare" was unfortunately of unknown lineage. So I do have hopes of a new pump doing the job ok.Do you run a twin pump setup?

I don't think you have grasped the simplicity of the Clubby Fergus- it's pretty basic. It doesn't really have an ECU, just an ign module. So there's not going to be any fuel pressure monitoring going on!

Good question. Again the Clubsport is not exactly highly sophisticated in the downforce dept. The aero consists of a splitter at the front and gurney flap at the back.The quali times (according to TSL) for last year's snett race make interesting reading.
GK with 1:05.546 in a PR6 to the slowest Clubsport at 1:18.24! It was similar weather on sept 26th.
The fastest Clubsport time was Mark Boot at 1:14.863. The fastest race times were similar to qualifying (although the slower Clubbies got a bit quicker).

There was a really warm test session at Snett circa July 2007 just before the Bikesports meeting that year (for which it then rained in qualifying) where there was a huge amount of rubber down on track and I distinctly recall the CS times dropping to 1m13/1m12 which was loony. So much so I used as 17t front sprocket in that meeting as an experiment. Everyone was putting in berserk times but it was generally accepted this was a 'one-off' and it stood in my mind for that reason.

Sounds like you were "on it" to an extent then! Don't under estimate the aero affects of a guerney flap. Their circa 15mm contribute a lot!
So although I can't possibly agree with Fergus as a matter of principle, looks like he was right that the Clubsports could go a bit quicker than I did.Bert
Looks like the fastest lap in the last race was quite a bit quicker Bert.

I'm chasing your garage profile! I'm aiming for a 996 RS / 997 GT3.1 or an SR3 RS next year!!!
