The entire bubble of cars, and the auto industry, is fascinating some days, boring others, competitive, ruthless, focused on cost, a ton of technology, and a bunch of old school stuff that we often overlook or conveniently omit.
Today we watch videos of this and that, of cars with incredible performance, and almost ridiculous horsepower ratings. Its all cool...
Internal combustion engines remain heat engines, that generate heat, and need to be cooled to stay in one piece. Although with technology one can build in a bunch of safety measures. The old school way was that you needed a ton of oil on a high performance engine, you needed a bigger than smaller radiator, and you needed an oil cooler.
Yes...you could do a couple of flat out runs before the temperature went up too high, but if you wanted to run that engine at higher revolutions you absolutely needed to keep it cool. Especially if you had 3.73 gears or higher, or you had a lower ratio and wanted to cruise faster.
The same with brakes, hopefully you never had to experience drum brakes on any vehicle. If you did, and if you got creative and swapped engines. You perhaps discovered the inadequacies of drum brakes, and brake pedals slowly hitting the floor while the brakes are fading into oblivion. Or a brake line bursting and literally running out of brakes.
This is old school stuff that most folks have never experience, and no longer exists with modern cars.
But...in our case the old school perspective persists, if there are 400 HP under the hood, there had better be at least 50% more power in the brakes. To this day we have little patience, understanding with brakes that do not perform aggressively to scrub off speed.
Yes...you need gas to make horsepower...today you could probably run an engine on 70 octane and it would be sort of cool. While most engines and some for reasons of being "politically correct" run on regular gas.
Here is the deal...
When an engine has 400 HP and a compression ratio of 10:1 it will run on regular, but will run better with premium. Back in the day one would pick a gas and tune the engine accordingly. Today the engine management system quickly recognises a better grade of gas and tunes the engine accordingly.
Yes...VP Racing Fuels do a ton of business at races selling gas with a higher octane than is available as premium at gas station.
Some things never change...
