So My STI is 2.4% higher ratio than my WRX was if I have the right ratios and did the math right, so I was high in my estimate.  Still, That should be 72RPM at 3000RPM and basically 100 at 4000. Doesn't seem like much but I sure noticed the drop when I changed cars. The WRX just sounded like it was whining down the road at 70+.
What is interesting is how 5MT 4th is almost identical to 6MT 3rd. |
Huh?
Since when is 0.972:1 "almost identical" to 1.761:1?
Did you mean the 5MT's 4th compared to the 6MT's 5th? 'Cause that's the whole point of the 6MT... is was *never* related to fuel savings while cruising... the top 2 gears in both boxes are
supposed to be nearly the same.
The 6MT adds an extra gear down low to allow you to stay in the boost better when rallying under 100mph. The point of the 6MT is to add acceleration on the low end, not fuel savings on the top end.
