6spd tranny?

[mpeters6@rochester.rr.com (Marc Peterson)]

Yeah, the overall levels are higher, but the 8v's seem to be in their torque
band for 3500 rpm, were as the 16's seem to be in their torque band for only
2500 rpm.  The locations of the torque bands are different, and the values
are different, but the width of the band is larger for the 8V's, that's all
I'm saying.  Which means that the 6sp might be more suited for the 16v's by
being able to keep the rpms in that band due to the extra intermediate
ratio.
