Hi Paul, Please can I have the whitebait and then the pie, and Sally would like the whitebait and then the scampi, we will decide on pudding on the night if that is OK, thanks, Robert ,

Hi Paul, Thanks for organising this, Sally and I are still coming, I will send our choices soon, Robert

2 places for us please Oli, Thanks Robert

Simon, no ECU that I could find, Robert

I have the spares box, do you need something from it sent? Robert

We waved you waved back

Hi, Please can I also ask to borrow a couple of passes for my parents for Sunday (once they are in I will return the passes to you), thanks, Robert

Yes please Chris

If racing about every 2 seasons, doing speed events much less often (5+ years) at a guess, and it is a full head rebuild.

The refresh alone is £500 and does not involve any modifications.

The estimate is £1500 to refresh and bring an ex-academy k-series engine to super-grads spec, and apparently it will improve a k-series by up to 10 bhp, depending on cleanliness of the current head.

One obvious issue is that 'super-grad' spec engines are not standard engines, and the cost to do this is not insignificant, but similar mods to non k 's are prohibited. So do we ban super-grad spec cars?

Steff, I agree, so why not make it simply 125bhp with an allowance for rolling road measurement error (say 4 or 5%)? As this includes all the standard cars described and allows some currently excluded, and hence is more inclusive. This would not detract at all from achievement of getting close to times set by Class 2. Rob, I agree it should be 125 + Delta not 125+/-Delta. Robert P.s. to clarify the owners of the two tracksport sigma’s who would have competed in 2013 had they been allowed, sold their cars before the regs were changed...

The aims must surely to be inclusive, forward looking and fair. The most inclusive is a simple power restriction. I agree ideally that should be 125bhp as this is what Caterham advertise their cheapest sigma as having. However that would exclude most of the current class 1 competitors, if last year’s rolling road figures are precise (I will come back to that), in addition it would mean that several Class records have been set in non-compliant cars. Clearly this is not inclusive and not reasonable. To be forward looking we must encourage those with newer cars to compete, hence the sigmas. I know of only a few sigma owning class 1 competitors since I have been competing, and two have stopped, one certainly as he felt the car was uncompetitive. This was partially due to the lack of LSD and partially due to the lower speed trap times for all sigmas meant he felt even with an LSD he would not be competitive. We must not make it seem like a k series only class. So as Gary has suggested would it not be fair to enable an owner to fettle the power up to closer to the most powerful cars in the class, after all this can be confirmed by speed trap data (currently at Curborough the sigma cars are 2mph (over 2%) down on the k’s.) I agree with him that measuring engine power is prone to many inaccuracies and so can only be used as a comparison (the data from last year gave sigmas (121.5 and 119) and k’s (130.1, 123.7, 128.2 and 127). So it would be fairest to say, as Clive suggests, 125 +/-4% to allow for errors in rolling roads, methods of measurement, atmospheric conditions etc. Robert

I have just sent a request, as a back up, Robert

Sally and I will be there, thanks for sorting this Oli. *wavey*

Yes please

Unfortunately it has chewed up the end of the drive shaft and the cup that sits on it...

Thanks to all who helped try to find the cause of the transmission noise coming from the rear of my car at Blyton. When we got back (after a slight in-car shower) it was a lot quieter but still audible. Gary, your diagnosis was perfect, the spring at the diff end of the drive shaft has broken in the middle. Thanks again, Robert Edited by - robj on 25 Apr 2014 12:26:46

Yes it had already had the tracksport kit fitted

Sorry but my car will still be in bits (after a diff and gearbox rebuild)... Fortunately Northampton MotorSport did a power and torque run before it was disassembled. I will be there, Robert

2 places please, thanks, Robert

1st dibs please

Hi Steff, I have driven on serveral tracks in the wet on both 539s and CR500s, and for fun I would go for the cr500s, more grip and more predictable even when low on tread. If you want to practice then go for the 539s. If it is as wet as predicted mind the kerbs, especially out of Seamans, Robert
