i was wondering what the lowest final drive gear ratio is available if one is looking for top speed. Of course someone would have to have a considerable amount of HP to utilize the gear to its fullest potential but I am trying to see whats available.

If anybody has any info on this and to what top speed it is good for, please chime in.

 

Mazda has a 3.636 that'll fit, from what I understand.

 

Feel like going 200+?

I think that would be right, not sure. Someone back me up with the aspects of top speed on those gears.

 

188.6 mph.

It's not like the stock car can even go the 167 mph that it's geared for, so why get all worked up about gearing it any faster? The amount of power needed to go that fast on level ground wouldn't get past the stock clutch anyway.

 

This whole thread is under the assumption that whoever buys the gear I am talking about (not me obviously) has a high hp motor with all the necessary upgrades. I am talking upwards of 400 hp. So the highest anyone can go on the currently available gearsets is 188.6 mph?

 

This is assuming that the Mazda gear will actually fit and that there is no other gear numerically less than this. A car with the aerodynamics of an S2000 may need well in excess of 500 bhp to achieve this sort of top speed, but I doubt the soft top will stay on. A Z06 might do it but it has much better drag coefficient than an S.

 

I considered putting that 3.636 final drive into my AP2 until I sold the car. It would have put the shift points for the lower gears very, very close to AP1 speeds (when taking the reduced redline into account.) (I preferred the taller gearing in the AP1.)

 

whoever does this i hope he or she runs their car on either a closed track or a closed air field. there is no point on going faster than 120 anywhere unless you're one of those "bigger is better"

 

It will also help imporve gas mileage if you care.

 

jesus I would never want to go 188mph in an S2k.. thats asking for a broken neck.
