4.57 at 80mph
Just wondering, what kind of RPMs are you at with 4.57 gears on an AP1 or an AP2 at 65mph or 80mph? I know the rule of thumb is about 500rpms over stock but I do not have an s2k and i dont even know what a stock cruising rpm should be at 80mph.

AP1:
65 mph = 3900rpm
80 mph = 4900rpm
AP2:
65 mph = 3800rpm
80 mph = 4800rpm
As you can see, there is little difference in rpm between the 2 cars. Honda designed the AP2 tranny so that the highway cruising rpm didn't change much.
Stock AP1 is 3500 rpm and 4300 rpm respectively. Stock AP2 is within about 50 to 100 rpm of this.
