Hey guys,
I was feeling nerdy today. So, I did some calculations and created some graphs to compare the stock Mazda 3 5-speed manual transmission versus the Mazdaspeed3 6-speed transmission when used in a regular Mazda 3. The data might be useful for those interested in swapping the MS3 transmission to their Mazda3's.
Variables:
- Overall tire diameter based on stock 2004-2009 Mazda 3 17" wheel/tire package (205/50/17)
- 5-speed transmission ratios taken from 2006 Mazda 3 specifications
- 6-speed transmission ratios taken from 2007 Mazdaspeed3 specifications
- Final drive ratio for 6-speed gears 1 through 4 (3.941:1) used for gears 1 through 6, with the equivalent ratios for gears 5 and 6 calculated (Remember, gears 5 and 6 have a final drive of 3.350:1)
- Maximum engine speed of 6800 RPM
Now for the resultant data (pretty self explanatory):
My conclusion: This upgrade is worth every penny and all the headaches!
As always, thoughts and comments are welcome.
