TJR: I talked a great length with Ford SVT Techs. My Cobra must remain streetable, dependable, fairly fuel efficient, and remain fun to drive. In talking with the SVT reps, they tell me that the best comprimise is the 3:73 gears. As per their statements, quarter mile times should drop by .5 seconds, 0-60 mph times should drop by .2-.3 seconds, top-end speed should rise by 10 mph due to the lower gearing allowing the use of 5th gear as the fastest gear instead of fourth. Highway mileage should drop by 1 mpg. I currently get 25 mpg at 80 mph on cruise, 18 mpg in town driving. I race SCCA road courses and require the punch and top end speed I can gain with a 3:73.
We discussed the 3:55's, 3:73's, 4:10's and all others. They claimed that the best gearing I could use was the 3:73.
Thanks
