SUNNY Z Posted April 4, 2014 Share Posted April 4, 2014 Using the weight, the length, and the fulcrum point, you can pretty solidly make a calculation. Its just a lever. a Third order lever in this case. Quote Link to comment Share on other sites More sharing options...
SUNNY Z Posted April 4, 2014 Share Posted April 4, 2014 Fe = Shock weight needed (total for both) Fl= Hood weight (42#) Dl= Length of the hood De= Distance from fulcrum (hinge) to point of load Fe=(42#)(4')(.5') ....... Roughly So Fe= 84# , making each shock a 40#. I might be way off base, but thats what physics says! Quote Link to comment Share on other sites More sharing options...

SUNNY Z Posted April 9, 2014 Share Posted April 9, 2014 Josey, I had no idea a kit like this existed. I made my own that is shockingly similar, simply because I had the shocks left over from my G35. They are lightweight because I have a fiberglass hood but I could at least give you the compressed and extended lengths and you could experiment with load rating. To make these I pilfered four connection balls from VWs, cut two flush and welded them to the hinge and made L-brackets for the other two. I had to play around a lot with mounting location to get the distances correct for full compression and full extension. Works extrememly well with my hood. Model I used: Suspa C16-13313 Extended length: 13" Compressed length: 9" Those show 30# /ea ... http://www.ebay.com/itm/SUSPA-C16-13313-12-30LB-GAS-PROP-STRUT-SHOCK-/230380316352 I hope to play with this some tonight.

socorob Posted April 10, 2014 Share Posted April 10, 2014 If it works out, please post some of the mounting distances from common points on the car. Quote Link to comment Share on other sites More sharing options...

socorob Posted April 10, 2014 Share Posted April 10, 2014 Litmans hood looks to be fiberglass in his pictures. Thats probably why 30 pounders worked for him. Quote Link to comment Share on other sites More sharing options...
Litman Posted April 10, 2014 Share Posted April 10, 2014 Litmans hood looks to be fiberglass in his pictures. Thats probably why 30 pounders worked for him. You are correct (see my initial post). They were originally used on my G35C carbon fiber hood. I got lucky that they worked equally well on the fiberglass Z hood given the difference in mounting geometry.

SUNNY Z Posted June 16, 2014 Share Posted June 16, 2014 Any updates guys? I've focused my time on getting my car running. It will be a side project once its on the road. Til then..... a stick will suffice. Quote Link to comment Share on other sites More sharing options...

thezguy Posted August 27, 2014 Share Posted August 27, 2014 Well based on sunnyz's bass ackward calculations and litmans measurements I ended up ordering a set of 40lbers with 14/8.5" lengths. I'm going to see what happens shortly. For $40 shipped its worth a shot. Quote Link to comment Share on other sites More sharing options...
