Mythbuster: continuing project thread of my 1303 '75

[-Alex-]

I didnt see any support on torsiontubes on your car and Humble's car, i have only seen support on mendeola oval chassis and remmele chassis.

Looks like they dont need as much support as the shock towers and framehorns.

First i wanted to have tubes from rollcage mainloop to torsiontubes, but it might be not needed from what i have heard:

For most tracks, these trans straps are gonna be mandatory. We just made one from 6mm steel, 4 inches wide...

Alex, you are on the right track, the factory got lazy with the later production runs, many cars came off the line without even the two t/tube too body bolts under the back seat, if these are omitted, then yes, the t/tube needs tying in somehow, fitting the bolts and re enforcing the body at the bolt head is a good start, any extra bracing into the cage is better but it may fall foul of racing regulations/scruteneering at race events, check the local ASR's.

Thats what i thought, finnish vw fellow with 300hp on a splitwindow also thought that torsionbars need support more than just body bolted to it

I am thinking either cage tied to torsionbars or remmele style bars:

Very nice Alex, tho I think the Remmele solution is OTT and getting heavy for anything without a 800 hp Turbo Porsche motor, I like simple and subtle solutions that are hard to spot, then you can cheat a bit lol
Walter, is your's a clutch scatter shield?

[-Alex-]

Yeah, i think bars from mainloop to the torsionbar tubes will do the trick on most beetles.

Maybe, but I think what I felt could have been a change in toe on one side at the rear suspension, so the diagonal bar 'on the floor' (end of torsion tube to the mid of the main tunnel, as with the Remmele example, but less extreme, just one bar) would be most beneficial.

Spanner: yeah, scatter shield for clutch or flywheel retention is the correct term

Fitted and all



Today I was at a shop that coincidentally had an engine with one of the very early Engoine Plus heads on the bench.
So I compared a little
