[QUOTE="mikeeg02, post: 1399128, member: 24194"] Please don't take this as criticizing, I need to understand something a little better here. And maybe I am misunderstanding how engines work, but isn't torque just a measurement of the horsepower at a certain RPM? I'm having a hard time grasping your concept on how part of the stroke makes horsepower, and part of the stroke makes torque. TORQUE = (HP x 5252) ÷ RPM By going to a larger nozzle, we inject faster, so that we can raise our peak horsepower RPM? And to keep that smooth/linear to your new peak HP rpm, you may "lose" torque at a lower rpm, possibly because your actually injecting a little less fuel at that rpm? (Think CC's of fuel, not injector pulse width) But if you allowed the faster injector to inject even more fuel at a lower rpm, you would in fact make more torque and thus give you more horsepower at that rpm? ( This is assuming your turbo was designed to work at that specific RPM and give you an ample amount of air, or if you didnt care about EGT's) I guess thats all my questions for now. [/QUOTE]
