The End all to Weight Reduction
Weight - Your basic 5 speed coupe without driver weights 3250lbs. So with an average driver weighing about 180lbs that puts your race weight at 3430lbs. At that weight and a power to weight ratio of .075 you would need 258RWHP to hit 12’s. Power to weight is the power of your car (rear wheel) divided by race weight of the car. Using my car when I broke into the 12’s first time I was making 246RWHP and had a race weight of 3250lb, which worked out to a .075 power to weight ratio or .075RWHP per pound of the car. From what I’ve seen a car can get into the 12s with a .075 to .080 P/W ratio. So if your race weight is 3430lbs then 3430 * .075 = 257.25RWHP. As long as you keep this ratio in the .075 to .080 range you are fine plus keep in mind you can drop weight instead of adding power. An example of this is a car with a 3000lb race weight could break into the 12s with 225RWHP (close to stock power on a GT). –thanks Code3gt
