tir33d Posted October 18, 2020 Share Posted October 18, 2020 (edited) I just raced at Bathurst in Australia with my highly modified 280zx. Mixed weekend with a 5 sec PB for qualifying. Racing was a bit too serious for my liking over the hill in race 1. Race 2 managed to snap another drive shaft. Race 3 from rear of grid was awesome. New PB 3 seconds better again. 2m18.7 man I’m happy! video is TV coverage of practice IMG_4126.mov Edited October 18, 2020 by tir33d Link Quote Link to comment Share on other sites More sharing options...

tir33d Posted October 25, 2020 Author Share Posted October 25, 2020 Wish I could put up a in car lap. Powers that be reckon they own my footage from my camera. Quote Link to comment Share on other sites More sharing options...
tir33d Posted October 29, 2020 Author Share Posted October 29, 2020 So, purely for diagnostic purposes, I have a video. Ummm just trying to work out a noise....... Quote Link to comment Share on other sites More sharing options...
260DET Posted October 30, 2020 Share Posted October 30, 2020 Put your footage up, stuff em, what are they going to do? Sounds like bull**** to me. Noise? Drivetrain eh. Nice speed through the Kink, fags backing off there need some brave pills. Quote Link to comment Share on other sites More sharing options...
tir33d Posted October 30, 2020 Author Share Posted October 30, 2020 Lost a tooth on each of the 3rd gears. new one on the way. power out on start was isolator flicking off on change to 3rd gear. Had me stumped for a sec. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted October 30, 2020 Share Posted October 30, 2020 That noise was entirely 3rd gear related? Seemed to be happening regardless of gear. I had a similar one on my car, could only hear on decel. Turned out my driveshaft AND CV bolts had loosened. I safety wired the CVs and double nutted the driveshaft and haven't heard it since, but I'm just autocrossing, so not nearly as much chance to hear things like that. Can you add more hood vents? Under hood air looks like a problem for you. 167 mph on Conrod. Very impressive, and agree with Richard, nice job resisting the lift at the kink! In the sim-racing world, it's a toss up for me between Nordschleife and Bathurst for me. My two favorites. Hope to some day get there and drive something, probably a rental Kia around it. Inspiring stuff, thanks for sharing. Quote Link to comment Share on other sites More sharing options...
tir33d Posted October 30, 2020 Author Share Posted October 30, 2020 My 3.25 ratio is rarely used, I am actually gonna re-lash the gears this time as I forget tooeach time I use it. I have been waiting for some new vents from the USA for 3 months now. They should arrive soon I hope. bathurst is a hard track to build confidence at, zero room for error for over half of the track. pretty proud of not lifting for the kink too! 1 Quote Link to comment Share on other sites More sharing options...
tir33d Posted October 30, 2020 Author Share Posted October 30, 2020 Not my first rodeo on driveshafts either. Quote Link to comment Share on other sites More sharing options...
tir33d Posted October 31, 2020 Author Share Posted October 31, 2020 Yes all 3rd gear too. Quote Link to comment Share on other sites More sharing options...
260DET Posted October 31, 2020 Share Posted October 31, 2020 If I was doing a LS swap again a dual clutch transmission would be on the list for sure. Kits are becoming available for the LS too, faster easier shifting and less stress on the drive train. Quote Link to comment Share on other sites More sharing options...

I weighed the costs of it against a T56 and the heavy duty 5 speeds transmissions and it was comparable. With the right ECU you can automate downshifts with throttle blip and all. Amazing what parts are becoming available for our cars. Really cool to see a Z banging around Bathurst with GT3 and V8 Supercars in the mix. Go team Z!

JMortensen Posted October 31, 2020 Share Posted October 31, 2020 Richard's offhand mention got my wheels turning too. DCT looks doable for about $5K all in... Quote Link to comment Share on other sites More sharing options...
260DET Posted November 6, 2020 Share Posted November 6, 2020 (edited) Unfortunately in my part of the world Jon this DCT gear costs twice as much, of course I could get a certain make of car that has DCT stock, that's a thought?????? Cary, that 280ZX has a massive roll cage particularly around the A pillars, I don't know all the detail but I'm suggesting that it's rigidity trades weight for grip and comes out in front lap time wise. At Bathurst lap times are made or lost along the top of the mountain where large gonads + a tight predictable chassis count.
