Just thought I would share this thread. It has some very good information but a lot of bs to weed through. I plan to see if it holds true at the dyno day. According to the thread, peak torque tends to be where peak load is logged. And, hp on the wrx is roughly equal to g/s of air flowed as read by the ecu. Again, kinda doubtful, but going to be at the dyno day, so we shall see! http://forums.nasioc.com/forums/showthread.php?t=1099390&page=3&highlight=calculated+load
I like to see if it holds true as well will wait for your dyno vs theroy comparison heres a theory number v21 hp.vs.tq
Well peak torque comes when the motor is operating at its max efficiency and more load means more boost so that makes sense. I'm going to have to read through this later today but I've got class in a bit.
