Drax240z Posted April 19, 2001 Share Posted April 19, 2001 I'm going to be running a 77 trans, with 3.36:1 R180 until I grenade it. An R200 3.54:1 is sitting here waiting for me to get to it, which I figure will make for a nice highway cruiser.

Kevin Shasteen Posted April 19, 2001 Share Posted April 19, 2001 Randy, There's more to rear gears than simply "Rear Gears". What engine/trans combo are you currently running & will your eng/trans combo change in the future? Cruising speeds and 1/4 mile times are usually good "Rules of Thumbs" to go by when picking your trans/diff.gears & tire diameter! Oh, yea: dont forget tire diameter! What would you like your rpm's to be at cruising speeds? Usually cruising speed is 60mph; but if your reguarly cruising at 80mph(?)-time for a 6spd(?)! If you go to the first page of HybridZ click on the "Contents" page; then scroll downward almost to the bottom of the page where you'll find the heading "Info" and click on that. Then you should see three more headings-you want to click on "Trans/Rear End Design Studio. This forum allows you to inpt your "trans/diff.gears/tires" or choice and then indicates your rpm'mph. This room allows you to alter your input which changes your rpm's/mph till you find the setup you like!

randy 77zt Posted April 19, 2001 Author Share Posted April 19, 2001 to kevin & drax-i run a 82 trans with 3.54 but last saturday i changed to a 88 3.7 lsd.one of the reasons for my post is that i suspect the east coast members dont drive as fast as west coast people do.at 80 with 3.54/82 trans with 205/60 15 tires it is running 3000 rpm.drives ok but i have subconsciously reached for another gear a few times after settling in at cruise speed.to drax-when you can ditch the 77 trans for 82/83.77 trans has big ratio gap between 2nd & 3rd and 5th is to close.at sears point between turns 2,3,4 that trans has wound in 2nd or dogging 3rd.i will be running 3.70lsd and 225/50 15 kumho slicks to motorsport show.hope it doesnt rain.
