Nice job!!!


Mike,

We have just had the noise decibel test passed in NZ, I think we are a bit easier here with 95db at .5 meter (your 2ft) and a V8 @3000rpm, and if you hold a race license add 2dba, and another 2dba for a mechanical engine = 99DBA. The bottom line is I aint revving my 8000rpm engine up to 75% for any **hole, I think in your case over there I would limit the engine to 5000rpm and that would make 3750rpm, stuff plenty of mufflers baffles etc and then take it off after you get the OK.

We dont require this at certification time, but if the Police pull you over and measure it/green sticker the car, you have to go to a Warrant of Fitness depo and get it tested and make it pass the test.

I think its just stupid of your govt to make excessive rules, with the small percentage of retro sports cars etc on the road, most using old engine technology, and you arent allowed to use a Carb, must use EFI! wind the fuel injection up and it will still billow unburnt fuel emissions. Have you still got the silly rule where the Smiths gauges have to be non-glare like no chrome bezels, I suppose you have to blacken out the chrome windscreen as well.

My car has original type door latches (MGTF) and they dont allow them here, so I told the certifier I am using them period, the doors will have the latch handle immovable/doors fixed at the time of certification, he said I dont know about that, the doors will have to be permanently fixed, ........rubbish, I said if the door isnt used to entry/exit the car it doesnt have to open, providing the car has no roof. As you can see I have got a very short fuse for bulls**t regulations!!
