Just saying that it appears your gains were more in hp than tq even if you use the factory specs compared to your dyno #'s. That would illustrate that by adding the SC you gained more hp than tq.

well anyone can feel free to correct me if I'm wrong but as I understand it - you need both for a strong AT street motor. and the wider the overall bands, the easier it is to drive, cause you don't have to shift as much to keep the motor in the "power band"... w/an AT car, low end torque is more useful than w/a manual trans, cause when you start in 1st - you can't rev the motor and can only use what it makes from the stall point on the TQ converter and up.

so for example, on my old gal - it's designed to pull like a beast from 2k rpms (w/a 2100rpm stall converter) for maximum off the line yeehaa, but then at 5900/6k or so it totally pukes and dies. but that's ok, cause it auto shifts at about 6k or so anyway, and drops perfectly back into the middle of the power curves. it'd be a waste for a manual trans car to be like that though.

w/a manual trans - you can control the shift points and don't need all the low end grunt - which allows you to tune the motor for even more high rev power. ie since in the NA world high end power and low end power are somewhat mutually exclusive. so one must decide where to put/balance the power (tq vs hp) - and the trans/usage will mostly determine that. then it's just using bigger pipes, ports and cams for high rev power, smallar stuff for low end grunt/within limits, etc.

course w/FI, you can just change pulleys, or turbo sizes to tune power profiles, and most of the typical NA controls (cams/port sizes, etc) can be overcome to some extent. but I suspect if someone punched out the heads/cams/exhaust on a 5 speed 5.0L and huffed the heck out of it like the stang and vette guys do - you'd see more 600rwhp sharks shredding the streets (assuming drivetrains and licenses held up ok)

Though a vast generalization and only an analogy, it takes torque to move weight and horsepower for acceleration. The heavier the car, the more important torque. The lighter the car, the more importance is horsepower. Then again I could be completely wrong.
