Racing Gen I & II was more a matter of heat management that who could drive the fastest around the track.
Running full throttle over 4,500 RPM put more heat into the engine than the radiator could remove. You needed to go up a gear on the straight aways to alow the engine to cool down enough to allow you to reserve enought cooling to go full throttle out of the tighter corners.
In a similar manner the brakes tended to overheat the brake lines, and cause the fluid to boil. We put in metal lines, porsche air deflectors, changed out to higher boiling point Castrol fluids. The brakes also tended to flat spot the right front tire.
Pulling into the pits after a hard run required drivers to raise their hoods to cool the engine enough to go out again for the next stint.
Putting on a supercharger just caused all these issues to get worse.
Gen III cured most of the cooling issues, and the brakes had far less tendency to fade.
