00GT said::shrug: Don't the Machs and new GTs both have 3.55 gears? The new GTs have a taller tire than the Machs effectively cutting their gear ratio to about 3.31. The new GTs and the Machs both dyno very similarly. The GT weighs about 150 more lbs. though and has taller effective gearing.
your right.. i meant to say they have taller gears than the old GT's. i don't know what got me thinking of the mach except that it has relatively equal horsepower.
