Same amount of fuel, same air/fuel ratio, simple as that.
Are you sure Stav.....? We see time and time again Norris Designs dyno plots on two types of fuel (road & race).....with the octaine numbers only 6 or 8 RON different BUT an extra 150 - 200 BHP on the race fuel graph. I thought this was purely down to the more potent nature of the race fuel.
