blueovalz Posted November 15, 2003 Share Posted November 15, 2003 Any targeted torque figure? 400hp at 4000rmp is a different animal than 400hp at 8000. I've got a WC-T5 behind a 289, and it handles an estimated 330lb/ft of torque (380hp) very well, but thats at a higher rpm than most are comfortable with.

blueovalz Posted November 15, 2003 Share Posted November 15, 2003 Thanks, but I'm no pro (if I was, I'd have some shiny paint on this thing by now). Transmission is a personal preference. For me, my car is the embodiment of old school hot rodding brought into the 21st century. Fat tires, manual transmission, rough idle, and the appearance that the only person that can tame this beast is it's creator. Personally, I love the manual, but it is more complicated to install than the auto is. Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted November 15, 2003 Share Posted November 15, 2003 One thing I consider to be of utmost importance is "overdrive". Without overdrive, you will not enjoy driving this thing on the highway. With a T5 in 5th gear (0.68 to 1), 24.7" tires(245/50/15), and a 3.545 rear gear ratio you will be running 2300 rpm at 70 mph, and 4900 rpm at 150 mph. With a C4 (not including slippage) you will be running 3400 rpm at 70 mph, and 6000 rpm at 124 mph. Whether you get a T5, Tremec, or an automatic with overdrive, get a tranny with overdrive!!!!!!

blueovalz Posted November 16, 2003 Share Posted November 16, 2003 There have been a couple of different approaches toward the manual transmission install. I do not know enough about other's approaches to add or comment on them, so I'll instead describe my approach. I am using the road track version of the T-5 which has a .80 overdrive gear. You may want to find one a little taller than this (e.g. .65 or so) because with my 4:11 gearing, 70mph hovers around 3K. Anyway, pressure plate movement is provided by a McLeod hydraulic throwout bearing, which gets rid of all arms and parts that normally take up space outside the bellhousing in the transmission tunnel. The master cylinder for this can be any aftermarket (Tilton, or Girling for example) 3/4" bore type. Most of these aftermarket MCs have the bolt pattern that very closely matches the Z bolt pattern. I have a heavy (high sprung) pressure plate, so I chose a 3/4" MC. For those using a lighter clutch could probably do well with a 7/8" as I think some have done. This will provide quicker action along with additional pedal pressure. Quote Link to comment Share on other sites More sharing options...

gene_w Posted November 19, 2003 Share Posted November 19, 2003 Hey, Terry, you don't have any spare T5 parts laying around, do you? I recently got a hell of a deal on a couple T5s. Unfortunately it turned out to not be quite such a hell of a deal. One of the trannies is pretty much trash, but the other one seemed pretty decent. That is, until you look at it in good light. The roller bearings between the main and input shafts were toast and the heat from those ruined the input shaft, main shaft, 2nd gear, 3rd gear, and cluster gear. Pretty much the whole thing! I've got a good main shaft from the other tranny, but need the rest of the parts. Where can I get ahold of one of those hydraulic throwout bearings? A few people around here say that one doesn't exist for the T5 trannies, but obviously that isn't true! Thanks, Gene Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted November 20, 2003 Share Posted November 20, 2003 I am using the following parts with my T5: Tilton P/N 61-601 Hydraulic throw out bearing Tilton P/N 61-612 Adapter (replaces input bearing support on T5) Tilton P/N 74-875U clutch master cylinder You can get these parts from http://www.colemanracing.com Quote Link to comment Share on other sites More sharing options...
