How's the steel bar work attached to the alloy extrusion chassis?

I believe there is some majorly reinforced gussets which bolt to the rails (you can see it in the render below better on the back legs)

Matt Close had to over come this with some careful cage work, and you know how anal he is about doing things right (Audi's are all alloy chassis too).

Heya all

From a rigidity perspective, bonding two dissimilar parent materials would be a great start. Production cars have been doing it for years, so there's some very advanced products out there.

Although I can't see CAMS allowing any non-mechanical (welding/bolting) joining methods anytime soon. The rules don't state you can't do both (bonding for rigidity and bolting to keep CAMS happy)...

Yeah but Close's cage did NOT meet CAMS requirements and as such was never able to be log booked.

Under AASA that didn't matter - not sure what he has planned going forwards though.

Stupid though as Maher sure proved it was up to a serious whack!

Alloy cages for alloy cars, and wooden cages for wooden cars.... problem solved

What are cams going to do if anyone wants to race a new mclaren (road car not gt3)? as the tub/safty cell is probably better than a cage.

When I stayed with him last december he was showing me why it didn't pass (nothing to do with being on an alloy chassis), but im pretty sure its now been resolved.

Nawww you guys.....

Heya 2PEE

That'd be cool to look over an old skool GrpA GTR. Does he regular SAU? Wouldn't mind popping him a PM and see if he's up for a chat.

No need to make rules to suit. I've scrutineered for CAMS long enough to see many different 'rule interpretations'

Pic of the RX7:

Mark!

Yeah, aware of the car....looks better without the bodykit. One of you came up one morning, whilst a minor

dilemma was happening and didn't have much chance for a yarn, never caught up subsequently.

Bloke in question, no, definitely not on SAU, 'bout the closest he'd get to a computer is putting G code in

manually on a keypad - which is close to your heart from memory. Can provide a number, but I'd guess most of the

Sadnut's foibles are pretty well documented now. An acquaintance may have a spare RB26 after putting a proper engine

into his gtr - if the worse should happen.

Precedent was set with the F40 all those years ago...didn't end well.....Octagon rulebook to the rescue??

[sav man]

You referring to Chas Kelly binning his F40 in Targa 92? Cages and helmates weren't compulsary back then

[2pee]

93, 94, 95 - should be somewhere in that timeline, Cams required ROPS

From my recall, there was a response of inserting a large object in a body cavity, when there wasn't going to be an exception for Racing Red.

This crowd does a carbon cage for 911's

thanks woo. spoke to him wednesday. and today. might have a task for you.

oh yes please!

[sav man]

Does anyone know if all of the 2011 compeditors are still getting the southen cross footage? The newsletters leading up to the event said we were going too, havn't havn't heard anything since.

No sweat, keep me in the loop

Heya 2PEE

You know of my previous exploits... I am a CAD/CAM/CNC programmer from waaay back I'm now in management and off the floor, but still have a play on the machines when I want something fancy!

If you think this guy would be up for a chat some time, could you PM me his number? I'm always up for a nerd to nerd car chat, especially if he has an engineering background!

As for the 'spare' RB26, I'm looking for something built for a trackable/reliable 350kw.

BTW, how do you know shit about me?!?! Damn car scene...

Mark

[Darkside]

^^^^^ I dont think reliable and RB26 belong in the same sentence Or maybe thats an oxy moron.

But dont listen to me. I am thinking of going rotary.... Thats a whole new world of unreliability.

But in reality, either engine done right can provide reliable service.

Heya DARSIDE!!

RB26 are indestructible compared to rotors. My first rotor (12a) made it over 250000 kms and was used solely for burnouts before I got it... It split two apex seals on the dyno as we were seeing how far we could go on stock ports. I still drove it everyday for a few months with split seals before replacing her!

If a rotor is built right and is shown some mechanical sympathy, it'll last a very long time. If you want to talk tech about rotors, I'm more than happy to help out, they are what I know well. Take my info, compare it to other workshops and decide what you think is best for your application.

[Darkside]

^^^^ That would be great Mark. After having just spoken to racing beat in the US about building a motor for me I am not so sure I want to sell all my organs plus any furure unborn children to have one of their engines. I am sure they are top notch, but circa 20-25k for a rotor engine build (complete long motor with turbo etc) is a bit beyond my budget.

But at the same time, happy to spend decent money to get something I hope will be reliable. Tassie is just too far to go for me to have a mechanical early on.
