Cali emissions numbers?
Anyone know what the pass numbers are for the CA tailpipe sniffer test?
I'm currently living in NYC, but I'm originally from the UK and maybe returning there at some point. If I buy a C5 here (probably modded), it'll need to pass UK emissions in order to get the car registered there.
The UK regs are:
CO 0.3% @ 2,000rpm
CO 0.5% @ Idle
HC 200ppm @ 2,000rpm
Can anyone give me equivalent numbers for CA? Having that would make it much easier for me to determine if a car would pass UK emissions regs because I could simply ask the owner or the tuner if the car would pass CA emissions.
Cheers,
Ian.

This is from a couple of years ago, but I think it's still current:
- HC: Max 128 PPM @ 15 MPH; Max 103 PPM @ 25 MPH
- CO: Max .80% @ 15 MPH; Max .60% @ 25 MPH
- NO: Max 1106 PPM @ 15 MPH; Max 936 PPM @ 25 MPH
So - it looks like the UK is a little more stringent on CO than California, and allows slightly higher levels of HC. Just FYI, I had a pretty highly-modded '85 up until last year, and it easily passed the sniffer test with 41/29 PPM on HC, .13%/.11% on CO, and 339/332 PPM on the NO. C5 should be much better than that.
