place your bets on my trackday mpg!

as you know, us ecomodders revel in good mpg!

however, i'm missing the thrill of a right good thrash
To this end i've booked a trackday at Official Knockhill driving experiences, Motorsport gift ideas and driving experience courses in Scotland
It's a 1.2 mile track with little elevation, 4hr session with 3 drivers
a) myself, a reformed leadfoot
b) my brother, a confirmed leadfoot.
c) the burd, capable of 57mpg uk in her petrol car.

The day will be run as follows I'll drive to the circuit in my normal 40mpg uk fashion

At the circuit, tyres will be dropped to 32 psi from 36 we'll each take turns to do 10 laps, consisting of 1 warmup, 8 'fast', and 1 cooldown lap.

At the end of each 10 laps, the car will be allowed to idle for 1minute to cool the turbo before being switched off for a 5 minute minimum cooling period.

Ideally i expect the car to complete 6 of these sessions in the 4hr period.so thats 60 laps at 1.2 miles= 72 miles.

I'll then drive back home in an ecomodding fashion with the tyres at 32psi


Total 'normal' mileage= 100
total track mileage= 72
total mileage= 172
at my current 40.5mpg uk, that'd eat 4.25uk gallons

I reckon my mpg overall will half- 20.25mpg uk (8.5uk gal) What do you think? Vote in the poll

Cheers! neil
