Hello again Carl,
based on what I have read, with stock set up on an 07, regardless of
heading up a slight grade or down, the consensus of those who have
had the opportunity, 114 mph is all you can expect. This is with a steady
speedo, not fluttering 3 mph up from & down from middle of flutter. Top
speed is believed to be controlled by the stock ECM.
I have also read that some are fortunate to be able to shift into 5th at
90 mph, with little modifications, from a flat out start. But let me say
this, if one is to hold 4th, somewhere between 80-85 mph would be all
that could be expected, it is the acceleration that carries some to that
90 mph level, so I've heard....Jack
Jack,
Does your '07 have a 110 with a heavy breather and 6 speed transmission?
The reason I ask is that my '08 does and my numbers are rather different from yours!
I took the opportunity for a little test today and came up with these results.
At 5400 rpm in THIRD gear steady for about twenty seconds 85mph.
At 5000 rpm in FOURTH gear I clocked a steady 102 mph.
Just curious.
