Gearing
 
Forgive me if already addressed but is it just me that gets the feeling like my M6 car could use a little taller gearing?? It just feels like 1st gear is more like a granny gear, makes me almost want to take off in 2nd but its too tall. 6th at highway speeds could use a couple hundred drop in rpms also. If I feel like this now I wonder how I'll feel after doing some major mods and gaining a lot of HP. (ADM) Anyone know of anybody who has addressed this or am I just nuts??

you could drop in the auto rear end... that would make the gears a lot taller! and would probably give you top speed in fifth. Not sure what the acceleration would do...
(also not sure if this is possible/feasible)

Stock manual at 6200rpm
1st 52.8
2nd 78.9
3rd 108.1
4th 140.5
5th 175.6
6th 223.0
reverse 48.4
(final drive ratio is 3.73)

with auto rear end:
1st 61.0
2nd 91.1
3rd 124.8
4th 162.2
5th 202.8
6th 257.5
reverse 55.9
(final drive ratio is 3.23)

That's what I was wondering. If there are any halfway options out there. A friend of mine who runs Prostock mentioned he once geared his a little taller when he discovered that his car actually run a couple of tenths faster when he took off in 2nd. After he re-geared it (4speed) he would drag as a 3 speed and use 4th as highway gear. I just figured it wouldn't hurt to ask around I'm just thinking out loud with my fingers today.
I may not be smart but I'm always thinking.

3.42 or 3.55s?

Could take 3.45s from a V6

Different ring and pinion gear size? Not sure of availablity of different gears for the ZL1 rear.

I put the zl1 rear in my SS about 2 months ago. As of then there were no gear options. Just stock 3.73, and 3.23.

That figures have to let the aftermarket guys catch up.

I'm in the same boat (zl1 m6). looking for a way to make 1st a little more useful with 700hp to the wheels and make 6th a little better on mileage for long distance cruising.

The best option would be to re-gear the transmission. Check with RPM Transmissions or Tick Performance to see if they have that option. They both specialize in building hi-perf manual transmissions. At 700 rwhp I hope you're not running regular street tires; but running a taller rear tire could help as well. You would be need to recalibrate the speedo which is not that hard with tuning software.

i think the auto rear end would be a neat option. What do y'all think would happen to the 0-60 and 1/4 times??

This was a pretty good thread explaining the different ratios, pros and cons etc.
