Nismo280zEd Posted February 10, 2009 Share Posted February 10, 2009 Well I was holding out for a long time trying to find the best way to mount this thing, I finally bit the bullet went to the machine shop and had my guy do the hard work. It came out beautifully, then Derek informed me he had completed is mounting kit with sensor mount and wheels lol. Oh well. This is how tight the tolerances where, he had .040" to play with for alignment of the screws, he also indexed them for me. I know the screws are long in that pic, I have shorter ones just haven't installed them yet. Won't be running the A/C anytime soon. Here it is all painted up and mounted. now to make the sensor mount. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted February 10, 2009 Share Posted February 10, 2009 I did it almost the same way but I wish I had opened up the center so I can check the main pulley bolt without removing the wheel. Did you put some locktite on the bolts? Quote Link to comment Share on other sites More sharing options...

Did you put some locktite on the bolts? Yeah I was actually thinking about that myself. cutting some away to get to the bolt. Locktite has not yet been applied, still mocking everything up. When it's go time I'll put some on. Quote Link to comment Share on other sites More sharing options...
1 fast z Posted February 16, 2009 Share Posted February 16, 2009 Looks like you mounted on the outboard of the rubber. If so (Cant tell much from the pics), then YOu will get slippage and your timing will be off eventually. Quote Link to comment Share on other sites More sharing options...
ZZZeee Posted February 16, 2009 Share Posted February 16, 2009 Where did you get the trigger wheel? What VR sensor are you using? Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted February 19, 2009 Author Share Posted February 19, 2009 wheel from DIYautotune.com VR sensor is from an 89 911 porsche. We are doing megasquirt on my fathers 911 as well and I scored two spare VR sensors form the project. I have not had time to mock up a bracket and test with a scope yet, but I'm sure it will work fine as it used to count many more teeth and more quickly on the 911. As far as slipage, are we talking like 5 degrees or? -Ed Quote Link to comment Share on other sites More sharing options...
olie05 Posted February 19, 2009 Share Posted February 19, 2009 If you mounted the wheel to the outer pulley you should be fine. Its the inner one (the one that drives the alternator) that is isolated by rubber and prone to slippage. How do I know? Mine came apart Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted February 20, 2009 Author Share Posted February 20, 2009 Damn... thanks Olie... It is mounted to the outer that drives the A/C. It's an experiment to see how well it holds up. I really like the setups Derek is selling, in the future I might go that route, or just machine the flywheel and hide all of it. Olie... what have you replaced it with? -Ed Quote Link to comment Share on other sites More sharing options...
olie05 Posted February 26, 2009 Share Posted February 26, 2009 I replaced the broken damper with another stock one. I was looking into the nicer bhj style dampers, but couldn't justify the cost, since my engine rarely sees anything over 6000rpm. The used replacement has held up just fine.

Zed2k Posted February 27, 2009 Share Posted February 27, 2009 I did this Machined down the pulley and bonded and bolted together with loctite. Quote Link to comment Share on other sites More sharing options...

Mine came apart Yes, the rearmost pulley is the only one suspended by rubber to soak up torsional vibration. The front of the pulley should be solid to the crank...at least that's how my double row 280Z pulley is. Quote Link to comment Share on other sites More sharing options...
