3.73 limited slip, will it slow me down?
Do you think the 3.73 LSD will slow me down in the quarter mile? Does it feel much more faster than my stock 3.23 on a 2000 M roadster. I know going 80 MPH, you will be going roughly around 4000 RPM, but how about, lets say 65 MPH?
I might be getting one installed on the 15th. I dont do that much high way driving, but if its going to kill my performance, I dont think I will wan tit.

Your 1/4-mile times will be noticeably quicker. You will be amazed!
Go to 368s.com and use their RPM tool to see what your rpms at any speed will be.

Unless you get a 6 speed a 3.73 IMO is a bit too much for a S52. You just do not have enough rpms to take advantage of it.

My opinion would be about the same as Florian's. An extra shift in there could negate any gain. I would not want to live with the higher RPMs on the highway, but I'm an old guy.
I am sure somebody has done this on an S52 if you do a search.
If you wanted to be quick only an S54 should easily take that gear. I used to run 4.11s on my 57 Chevy but I was 16 then.

I doubt that you would pick more that a tenth or two in the quarter. That little bit of acceleration improvement would be offset by: 1) higher highway RPMs, 2) lower fuel economy, 3) increased engine wear, 4) a 1st gear that is now very short, and 5) greater stress on the weak differential mount.

Hmm, so those drag racers running 5.60 rears have NO idea what they are doing?
Maximum acceleration is when you use all 5 gears and hit redline just past the timing lights. Check out how Pro Stock gears (they use 5 speed trannies).
As for the downsides, yes, higher PM at cruising speed, possibly a lower top speed (but may not depending on teh limiting factor), as for fuel econoy, the biggest hit will be you enjoying the fun feeling of nailing the throttle.
