I dynoed my car after installing the following:
-Mac mid tube headres
-1.6 RR with lt4 sprigs
-STP underdrive crank pulley
-alluminum drive shaft
I can't post the graphs, but this is what I gained (lost)

RPM torque change
3800 -18
4000 -12
4200 -8
4400 -5
4600 +20
4800 +24
5000 +24
5200 +30
5400 +32
5600 +35

There is a big jump around 4500 RPM.
The car feels much stronger from idle to 5800 RPM (limit)
A/F ratio is 13 all the way.
So my torque peaks now at 306 at 4800 RPM, power at 285 at 5300 RPM.
It was the same dyno.
Can dyno give false redings, because there is no way this car has less
torque at any RPM?
