As David has mentioned it's that time of year again, finally Marmelade came out of the garage and we headed off on a short trip across Suffolk to RAF Honington to join the Borough 19 guys for thier second sprint of the season.
The day started with relaxed trundling up and down the service roads learning how to use the new gearbox and after a stroll round the course and a bacon roll to recover it was time to go out and play. One we had learnt to use the gearbox it was FANTASTIC, even better than the first run out on the Avon ACB 10's which is saying something!
so anyway you dont want to read about it you want to watch it so here is David taking you mostly round RAF Honington

unfortunately the gearbox was made of chocolate and it was a warm day
oh dear.

Don't know what your normal DB's come out at but Goodwood's static is 105 db's on sprint events and testing. What do you pack your silencer with 
I used E Glass for years , re-packing almost for each event but then in 2006 I discovered BASALT at £35 a bag . It takes half a bag to fill my 22 inch x 6 inch can which has a 2.75inch through pipe . I very rarely get measured at any more than 102db's now depending on who does it plus the weather influence but at the last Goodwood test it came out at 99db's 
It's a 2lt zetec on TB's giving 231bhp 
-- hopefully see you at Abingdon.
