Has this ever really happened?

i HAVE HEARD IT HAS BUT NEVER SEEN ONE LIVE (THANK GOD) I HAVE SEEN THE FRONT OF A DS BREAK, HIT THE GROUND AND THEN FOLD IN HALF AND TAKE OUT A REAR TIRE

THEY SAY THIS HAPPEN BECAUSE OF THE DS BREAKING AT THE FRONT IDK HARD TO TELL

SOME CARS IN NHRA REQUIRE 2 LOOPS

I wasn't even thinking about those classes. That was me speaking out of ignorance, thanks for pointing that out.:snapout:

Fighting a similar packaging issue, it seems magnaflow likes to put the x-pipe in there exhaust kits right inline where a DS loop would go per NHRA spec

You have to follow the rules. But in reality an X pipe will keep the DS from hitting the ground..How can the DS get passed the X :headscratch:

An X pipe MIGHT keep the drive shaft from hitting the ground or, more likely, the DS would simply rip the exhaust out from under the car. Regardless, the X pipe would do nothing to prevent the shaft from tearing through the floorboard. In any case an X pipe would never be considered an alternative for the DS loop by any santioning body.

I still need to see if I want to connect the loop to my subframe connectors or run it straight back off the transmission mount.

But, if I ran it straight back from the trans mount, would the NHRA view two 1.5"x1/4" pieces of steel running parallel, but not connected to each other as good as one 2"x1/4" piece of steel. The ONLY reason I ask is that I already have some 1.5"x1/4" steel stock lying around. The loop itself would be 2"x1/4", and the plate that bolts to the trans would be something like 4"x3"x1/4"

Forgive my Microsoft Paint sketch. If I run a DS loop off the trans mount, this would be a top view with the transmission on the left of the picture. The DS would pass through the loop and out to the right.

I think Myth Busters did an experiment with trying to launch the car with a broken driveshaft....if I'm remembering correctly, they couldn't get a car to do it....
