RebekahsZ Posted January 23, 2011 Share Posted January 23, 2011 I searched for a thread on this and can't seem to find one. This is for drag racers or folks who just like to burn tires. Here are some pictures of my line-lock roll-control system on my 72 240z. I use it primarily to control movement of the car in the burn-out pit. Car has manual trans. I got the Hurst system from Jegs on-line. The system is actuated by pushing hard on the brakes, then pushing a momentary switch on my shifter handle; this locks fluid pressure in front brake lines. I can then release the brake pedal and do my burn-out. Release the button and the brakes again work normally. Little light on dash tells me system is engaged. Pics attached. Open to questions. Looking for in-put on how to install a 2-step rev limiter for LS2/T56. Quote Link to comment Share on other sites More sharing options...

LanceVance Posted January 23, 2011 Share Posted January 23, 2011 Sounds like a fun little accessory... have any closeups of the button on the shifter? How does it attach? Sounds like a poor mans launch control... How much did that set up cost you? Quote Link to comment Share on other sites More sharing options...
mr jdm Posted January 23, 2011 Share Posted January 23, 2011 on a manual trans car its not a "launch control" its just to make it easier to do a burn out. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 16, 2011 Author Share Posted May 16, 2011 I have relocated solenoid onto firewall while I was doing my LS2 conversion. Turns out I had incorrect nuts on the end of my brake lines. The Hurst solenoid body uses 1/8" NPT, while the SAE nut (red in my pics) is a SAE 3/16 line nut (I think the SAE thread pitch is 3/8X24); the metric line nut is 10mmX1.0 thread pitch. I did not have any leakage in 1 year of use, but I contacted the Hurst website. Proper plumbing is with an adapter 1/8" NPT male to female SAE line nut. I have tried both the SAE line nut and the metric nut: they fit the same with smooth thread engagement and an equal amount of play as you screw them in, so I used the NPT to SAE adapter with metric nuts and 3/16" line with double female flare.
