if you tuned it, it would be making 7523 ft-lbs and be posted upside down.
wasn't there another issue with an STP dyno posted here? Oh yeah, it was another TDR car when he posted here and we didnt give a ****.

You KNOW it.

By the way I asked for some measured data on VVT over there.
Is VVT usually capable of being tuned as opposed to just switched on and off at different RPM? I was under the impression that all VVT ran from oil pressure on a solenoid, or is that Oldschool now?
What components allows the VVT angle to be changed as opposed to open and closed?

I understand that fully, its usually powered by oil pressure and that pressure is controlled with a solenoid, I just cannot think of how the 'new modern' way of doing it that allows it to be stepped in angle, as opposed to naturally sit in one setting on a stop, and then have oil pressure push it to the stop a few degrees around.

sounds similar to honda's i-vtec
I'm trying to find the video I saw once that uses pneumatic valves which allows all valves in the head to be independently controlled from each other unlike a camshaft. It's a true Variable Valve Timing system. Pretty neat stuff. Just can't remember what the video was titled
EDIT: Found it
