drive shaft length
If in doubt throw a driveshaft hoop in it for peace of mind.
So you all know the drivesahft loop is only designed to keep the front of the shaft up in the event the joint breaks. That is all that is designed for, to keep the shaft up off the floor in the event it breaks to really get the car pushed out of the way, not to prevent the myth of pole-vaulting.
If you break a shaft from rpm related issues using a factory shaft that wasn't designed for those rpms when it winds up exceeding that you'll be sitting next to a built in shredder.
Neither loop will help you there, and loops have been cleared from cars when shafts break from rpm related issues along with floors, body parts and anything else in its way.
It's why the nhra made certain classes go to
scatter tubes like we have been using in boats.
After a driveshaft made incorrectly for the rpm it was seeing came apart and cut the car apart and the cage and pulverized the drivers entire right side, broken calf, leg, hip, ribs, shoulder, arm, head and helmet, she survived luckily.
