haha, what are you saying about my driving Bill I positioned the tank with the outlet at the rear, thiinking that under acceleration, all the fluid will be forced to the back when it's most needed, then under braking when WMI won't be running it'll be forward. I'm now wondering having seen the tank in the flesh if it's just too big in general! I did give it a lot of thought, but if I was in the wrong ball park to start with I didn't stand a chance..... How much mix would you typically use in a Saloon race at Combe? they're about 45 mins long arn't they? Do you just have a 1 gallon tank in the ibiza or is it a mega super dooper custom jobby as I'd expect?
