I have the "pleasure" of living in the state of New South Wales (NSW), Australia. We have a State Premier whose name is Carr, but who has never got his driver's licence, and a Transport Minister named Scully (belongs in the X-Files) who thinks that we all should be using public transport !!
You can imagine how sympathetic these guys are towards the "Individually Constructed Vehicle" movement. As far as I can ascertain, any newly registered car must meet the current Australian Design Rules (ADR's), with the only exception being related to crash testing (Thank God for small mercies !). The latest version of the ADR's (ADR 7900) came into force this January, and equate to the Euro-2 rules.
Having finished almost all of the car except final paint & engine, I am now looking down the barrel of these new ADR's and trying to figure out how to meet them.
There appears to be 3 big issues for a GT40 :
- Brakes : there is a strict series of tests which must be undertaken, but this should not be a problem as my GT40 Australia (DRB) has '87-88 Corvette brakes. In the 'Vette, these brakes will eat any testing, so should be a walk-over in a car nearly half the 'Vette's weight.
- Noise : This would be a real problem for a stock crossover / cats / muffler setup on top of the gearbox, so I will have to reserve this top space for cats & loop the system back to run through big & boring mufflers on each side of the gearbox. As a last resort, I could use the "temporary s/steel wool pot scrubber muffler enhancer" made famous by one of our most respected Forum members (name withheld for his own safety !!).
- Emission Control : this will be the killer. The car has to undergo a full test cycle from cold start, through the full range of driving conditions on a dyno, & exhaust gasses are continuously monitored. My guess is that these new ADR/Euro-2 rules are probably something close to the current California rules. I have come across some new "pre-cats" which are ceramic-based & come up to operational temperature much quicker than conventional units. These should help with the cold-start part of the test cycle. If I add standard (big) cats to these, perhaps I can squeeze things through (with the help of an Autronics ECU running lean & a high-temp thermostat).
These are only thoughts at the moment, but I can't help wondering if I am "re-inventing the wheel" - the big question is whether any of you guys have managed to get a 302 pushrod engined '40 through the latest ADR's / Euro-2 / California rules on emissions, & if so, how ?
At the moment, the only "safe bets" I have are the latest quad-cam Ford modular motor (big issue on how to fit it in), the Lexus Quad-cam (sacriledge !), or the GenIII GM 'Vette engine (more sacriledge !).
If anyone out there can provide some "war stories" on how they got their car through these tough new sorts of regs, it would be greatly appreciated.
Kind Regards,
Peter D.
