Cheers Graham! I believe 5 or 6 pairs have been made in this batch.

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:

Alex,

Copied from my same answer in Humbles thread:

The fact I didn't weld any supports to the torsion tubes, doesn't neccesarily mean I wouldn't be better of with them...
In fact, thats probably the first other thing I will add to the existing cage as my instablity at Santa Pod in 2012 might be due to missing exactly that!

Cheers,
Walter

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

http://ub-52.blogspot.fi/ (The tubechassis car is a different project, i have designed that rear suspension.)

http://www.youtube.com/watch?feature...&v=QOrhwTLF3hA

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?

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

One way is a short blind tube bolted thro the body to the t/housing end on using the existing fixing point, say about 200mm vertical, then one down from the main hoop welded to the vertical piece, then up from there again to the diagonal, that way you get a good triangulation , plus the cage can come out if required.

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

Cool comparison! The TP Heads have much more cooling fins and it seems longer ports also.The latest generation Engine Plus heads have also much more cooling fins than the previous ones.Thorsten really did a fantastic job on those heads! I´m really looking forward to this project! Hope you´ll be in Spa this year with it!

Not to sound like a schmuck, but I can do the same comparison with a version 9 Engine Plus head as we just removed the heads from Nigel's 2,7ltr to have a look at the abused chines Nickies he runs.
We only had time today for the 3-4 cylinder side and those cylinders looked top!
Think I made a pic if your interested.

I´ve seen the version 9 heads also.They are a big improvement compared to the first generations,mainly the casting and material,so Jan Lackstetter a few years ago.However, they do perform very well. I would like to see the chinese cylinders,thanks!
