Btw the torque curve can never just shift. If it changes, it will still cross over at 5250rpm.

I understand, the whole unit conversion causing the curve to cross that exact point every time. You get what I meant though no? lol Just more torque higher up in the range.

Yes. But Sean needs to be put back in his place.

That is incorrect. A change to a larger cam will shift the torque curve up. Horsepower and torque will still cross at 5250 but the peak torque will be at a higher RPM.

My guess considering what your current set up and readings are is about 7.5% increase at the rear wheels across the board with headers and straight pipe. 420rwhp/396rwtq. Ron how much did you gain with just the x pipe instead of the high flow cats? I know the 1/4 mile time went from 12.1 down to 11.6.

I'm not sure because I never dyno'd it but I picked up 4 MPH in the 1/4.

That is correct. Both numbers will just cross at a higher point in the 5250 rpm range. The curve has still shifted.

I was questioning his "Both numbers will just cross at a higher point in the 5250 rpm range". I'm just not sure how they can cross at a high point in the 5250 range. Maybe he meant at like 5251 or 5252.

By the way Throttle Crazy is my brother so I have to give him a hard time.
