Racers,
Im putting an 8-point cage in my 914 and I have a few questions about roll cage gussets: - Are there rules about what the gussets should be made from? Must be DOM? Pipe ok? - Id like to triangulate my joints with smaller diameter 1" OD pipe than what the cage is made of. - Are there regulations on where the gussets can and cannot be located? Im thinking of adding to the halo area above the driver, and the connection point of the halo to the main hoop. Id hate to add a bunch of gussets only to have it flagged for removal by SCCA or another racing org. Something like these: (IMG:http://www.914world.com/bbs2/uploads_offsite/image.fourwheeler.com-6222-1455665527.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/image.mustangandfords.com-6222-1455665527.2.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/www.miatacage.com-6222-1455665528.3.jpeg) |

whatever you choose to do..take heart - most 914's (historic 4's & 6's) can barely muster enough speed to cause major damage. (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/rolleyes.gif)

(IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/rolleyes.gif) maybe so, but having a faster car come up from behind in traffic on a fast straight away and have no where to go except to push you head on into a wall can make a well designed roll cage all the better..... |

Bill - True. For some reason...that phenomenon isn't an issue I'm generally dealing with - good thinking. In all seriousness, I get it...you're an engineer. This means a basis of an opinion usually accompanies a brief on one's career. Sometimes I just need to walk away... (IMG:style_emoticons/default/shades.gif)
Back on track: ONE of my greatest concerns on track is another driver losing brakes or having a major medical into a high-speed braking zone (anywhere in my vicinity). Based largely on that potential event - I have chosen to build and retain a full (intrusive) cage. Is it convenient for an aging driver? Not really. Is it safe-r (and help the flimsy chassis? Yep.

I guess my greatest nightmare is not what I do to my self in a race car at speed but what someone else does to me even when I am just stalled on the track standing still on the backside of a blind turn...Event though a 914 may not be the fastest on the track, they usually lump us in with a lot faster cars...so the reason why track days can be equally dangerous when I am out in my Miata at Willow Springs practicing with the big bore Porsches that have 40mph over me through turn 8.....for example watch this video. I have driven Road Atlanta in a Formula Ford and know turn 12 all too well.....The guy had no place to go. https://www.youtube.com/watch?v=RIdGGjMhL4M |
