If you want to just have a shot at going fast in a straight line, with no fear about speed cameras, head down to Santa Pod or Shakespeare County Raceway dragstrips, for a RWYB - Run What You Brung.
It's a good, cheap day out for racing (usually 30 quid for entrance including signing on, for as many runs as you can line up for) and you get to peruse/watch some very special machinery.
I guess it might get boring quickly in the 1850 but it is quite useful for working out how to get the fastest speed in the least amount of time out of your car
It can also help identify (or exacerbate
) any weight transfer, traction or powerplant/box issues!
