At least Ontario knows who he is "I'm just a dude playing a dude disguised as another dude." lol
Racing oils and coolant additives do work but they arent miracle workers. They dont stop your car from heating up but what you will notice, especially from using both those products combined, is that the car will cool down much quicker, even idling in traffic which is huge. I would see a good 10-15deg f drop fairly quickly back to normal. My B5 S4 had a higher oil operating temp (250 is normal). I sued everything i could to keep that car cool because of that. You may also want to see if they make a finned oil filter sleeve cooler thingy. With coolant additives you want to open the radiator and take out some antifreeze and replace with water. You could technically run straight water, but it can rust and is not recommended for street cars. Water is one of the most efficient conductors of heat(they use it to cool nuclear power plants for a reason), but it is corrosive to the vehicle so they use antifreeze. The additives let you run water without being corrosive. The water meth will drop your intake temps 20deg C, but again your still starting at a higher base line with less dense air and the maf is already compensating to keep your air density constant the best it can. For example the reason why Nitrous oxide (N2O) increases power in vehicles is because it is three times more oxygen dense than normal atmospheric air. Also the reason why it works so well on cars with turbo/superchargers is because the process of the liquid N2O, changing into a gas, also removes a TREMENDOUS amount of heat. Again cooler temps means more power. Bottom line is the colder your ambient temps is, the more power you have.
