What you need to ask yourself is what are you doing this for? Do you want to be faster in the quarter mile? Then go for a super charger. You can tune all you want, and add all the mods you want to increase the amount of air in the motor, but you'll never increase how much suction the motor is doing naturally. Doesn't matter how much tuning you do. That's why forced induction is so amazing, it's not just giving more air, it's forcing more air into the motor. At 14.7 pounds of boost from a super charger you've doubled atmospheric pressure in the motor so thats 470 hp x 2. The only reason we typically build up the internals of a motor is to keep the motor from falling apart when the parts designed for 470 hp meet that 940 hp, there's only so far the manufacturers designed this motor stock to go in the aspect of power generation. One reason tuning is so important is to bypass the fact that you'd have to design your power increase in so many different aspects so as not to have the computer counter your power adder just to save the motor. It's like keeping the computer on the same page as the parts that make up the motor. With more air from a supercharger or turbo comes more heat in the cylinders which leads to detonation, you can either raise the octane to avoid detonation or wait for the knock censors to say back down timing(good bye to your power) to save the motor. Anyways back to the quarter mile deal, if you want to be faster you need faster power, a supercharger is big on the power because it's almost instant power because it's forcing more air in, without it, your induction is regular and you're only increasing the air volume in the motor by maybe 10% or 20% your best bet on gains is about 100 hp. That's assuming you buy mods that were designed to work with one another. Lots of people follow a popular misconception that adding mods and calculating the increased horsepower is just a matter of adding the gains of each mod together for example intake(8hp) and exhaust(20hp) oh I must have 28 horsepower in gains! EGGHHHH wrong. That's assuming each mod was designed to work with the other, which is more than likely not the case half the time. Sometimes though it's not just about over all gains, more often than not it's about that power curve. Some modding will increase the point at which the power curve begins. Tune and bolt ons you could be under the 12 mark for sure, but with tuning, mods, and a supercharger you could be in the 10's lol. Hell for quarter mile you're better off just doing a wet shot of nitrous on a separate fuel system.
