To touch on Mines13's good point---my Goal is 15psi or simply one atmosphere of pressure. With 7.5psi, you are adding 1/2 the displacement worth of air (The "box 6 feeling" that has been associated with the Sprintex.) With 14psi, you are doubling the airflow of the existing engine. That would feel like a "Boxer 8", basically. 21psi would be a "Boxer 10". 29psi would be a "Boxer 12".
Goals are important. The versatility among the boosted options are a healthy thing. These are like different masks or characters for the same car  .
A "hit" of power or "yank" (torque)---Roots, twin screw, n/a--good for autocross or tight road course, drift (IMO...).
A "rush" of power, or "horsepower"---Turbo, centrifugal, nitrous---good for drag, standing mile, fast road course.
14psi making 400hp or thereabouts would tickle my fancy. I don't know if the valve springs could do it, though. These are supposedly weaker than the WRX. Anyone know for sure? |
Well worded, the 940cc is pretty much as small as you can go on this engine as far as charger displacement is concerned, this is excellent if your primary goal is response in torque delivery, that "3L, 6 cylinder" feeling we love to talk about. 400hp would require a larger displacement unit for certain. Honestly, we are not seeing close to that and it feels pretty nasty as is. I am more of a track/back road kind of guy however... More then enough to get the car to rotate at will on throttle in most instances; as the product will ship.
It was critical for us that this system only enhance the car, fill in the holes, improve driveablity and add to what is a brilliant enthusiast driver's platform. Not so much as to upset the original vision for the car... I strongly feel that you will agree that we have met that goal.
