Driveshaft loop approval

[boostin]

Hi there Justin,

Thanks for the approval.

Was wondering if you could OK this, or perhaps give me tips as to how I could improve this.

Is this up to LVVTA standards? As I own a S14 that's due for a cert; the first portion of the driveshaft is short as hell and my cat is kinda in the way, so I have to do some kinky bends to clear it (goodbye heat shield?!)



Please let me know what you think as I need to get certed ASAP for the removal of my greeny.

Cheers

Hi boostin - you've nearly got it sussed!

Just make sure that the 5mm thick pipe and flat sections each measure 50mm across.

Also, your doubler plate sizes are a bit small. A typical size plate meeting the requirement
of 3000 square mm would be a 50 mm x 60 mm plate, or larger.

Cheers, Justin

yes this makes sense, good effort with the sketch
I am waiting for my hobby car manual to arrive
for your information Schedule 40 seamless pipe is over 5mm wall thickness, I think its about 5.9mm. I am using 100 dia pipe as the universal joint will pass through it and leave enough of a gap for vertical movement, obviously the closer to the universal joint the less this becomes an issue.
so I cut a piece of pipe 50mm long and will use 50x5mm flat bar and high tensile bolts
