Basically started off with a random breath test on doncaster road near westfield. Blew clear, then like 20m down the road another lot were set up - the EPA for random emissions testing.

My mate got defected in his brother's 300ZX TT tonight - too low, bald rears and no number plate lights. What interested me more was that he passed the EPA random test. I will check with him tomorrow, but i'm pretty sure that this car has gutted cats... What worries me now is that if i get random EPA tested, will my car pass the emissions test...? It has a 'race cat' but i suppose the question really is - can the car still pass emssions without the cat?

Has anyone ever been random checked by the EPA?

OK, by what i know, they do the whole noise test and emissions test on the spot, i guess they'd do a look over of your engine bay too.

But still, CAN the car pass the emissions test without / with a gutted cat? Does anyone know?

Faulty or no CAT will definitely show up on EGA as they will get a high hydrocarbon reading. I haven't seen the equipmeny they are using at the moment but I'm reasonably sure they haven't changed the way they check. As for the $10,000 fine, I've never heard of this being issued against any individual.....has anyone else?

Hey Inasnt

I went for my EPA test at Macloud today... (I was suppose to go last week, but I had put it off till this week)

I passed the noise test right on the nose at 90db !!!

talk about close....

As for Emissions test - didn't even test it.. he said skylines run very clean - so he didn't bother to test it... The fact the my Low Fuel Warning Light was glaring him in the eyes while he did the noise test may have atributed to his desission not to do the emissions test.. :P

But the big thing is that the Sound test was done at 5100 rpm

(not the usual 3200 rpm that the exhaust shops test at)

He said that a Twin Turbo 2.6 L has to be tested at 5100...

At the EPA they work off a more detailed Vehicle Reference Book then the epa approved exhaust shop test centers have...

And as the test centers don't have the detailed book - they test at the default for a NA 6 cyl. which is 3200rpm....

They also also asked me if I had changed my exhaust since my last EPA test in november 2002 when it tested at 85db at an exhaust shop test center... I said "Yes, I changed it when I got this latest epa notice... if I am going to get epa notices while running with a 85 db muffler then I might as well run one that is 90db"

He said "fair enough" and passed me :P

sideways

they tested my car at 5100rpm 2. I was gonna ask them wtf they were doing but since it only read 83db with thew stock exhaust i used for that day i didnt say anything.

My car was actually running rich as they told me coz i put back on all the stock stuff which changed all the flows. Did a tall guy with glasses and grey beard test your car?

i think theyre supposed to test at around 3/4 of the redline

for engineers certificate for my rb25 silvia, it test was carried out at 5625 (3/4 of 7500) and did 89.5 dBa on (what i think is) a 2.5" full exhaust with canon (exhaust pics here)...this is nsw though, not sure on differences with vic
