Guest scca Posted September 13, 2000 Share Posted September 13, 2000 every where has different rules but in SCCA/roadracing there is supposed to be at least a 1/8"(mine is 3/16) plate bolted to the shifter tunnel inline with the clutch /flywheel assy so it cant take your foot off if it explodes. i dont know NHRA rules that well but i believe they require a shield or a blanket over the tranny. i saw one car lately that had a tunnel made of 1" billet plate alum. nice and lite and as strong as 1/4" steel. that will be what i do in the next car i build. also everyone should consider a driveshaft loop front and rear to prevent it from escaping they are easy to make and more likely to break than the clutch assy. and does a hell of a lot of damage when it thumps around in the tunnel without any guides to control it ------------------ Mike http://www.fonebooth.com raceparts and brakeupgrades Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 13, 2000 Share Posted September 13, 2000 I have pics of my driveshaft loop, out of the car at: http://members.home.net/pparaska/drivelinemods.htm Simple to make and install. I have it about 4 inches from the U-joint in front. One for the rear would be similar and a good idea! Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted September 13, 2000 Share Posted September 13, 2000 Pete, what would it take to have a copy of your loop made? Either the specs or have your machine shop make another. ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 13, 2000 Share Posted September 13, 2000 Scottie, time is really precious, so I'll decline on making one. It should be made with the car available anyway, as it's a tight fit. I was underneath the car probably two dozen times as I made it up. But with a template of mine it should be easy to fit to any Z. The layout of the trans, etc. is critical for getting it right. I'd suggest making the loop part first and measuring for the mountinf arms after that. I can scan in a dimensioned template and put it on my web site. I'll post to this forum when it's up. Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 16, 2000 Share Posted September 16, 2000 I have a full scale sketch of my drveshaft loop with some dimensions on my website at: http://members.home.net/pparaska/image/drivelinemods/loopsketch96.gif Scottie, I hope that helps. I wish I could make one for you, but I'm afraid it'd be wrong without having your car where I am making it. My shared welder is about to return to the other half owner for a while as well (sniff).

Scottie-GNZ Posted September 22, 2000 Share Posted September 22, 2000 Pete, here is a delayed thanks for the driveshaft loop diagram. I finally moved into my new house this past weekend and I am halfway towards getting things back in order. ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 23, 2000 Share Posted September 23, 2000 Glad I could be of some kind of help anyway. Have fun with the new place! Hope you moved "uptown" as far as garage space goes! Quote Link to comment Share on other sites More sharing options...
