Well, I've been reading a couple of posts about people having problems passing emissions in some states. Thought I would have a problem here in NJ with the mods I now have. I didn't find any place to buy methanol so I figured what the hell, let me see what happens.

Right now I have about 1700 miles on the engine since rebuild. I made sure to have it fully warmed up, was driving around for at least a half hour prior to the test and made some full boost runs.

I told the guy at the inspection station to slowly hit the gas to stay off boost when he did the dyno test. Results were:

.............standard.........my reading
NO 1045 ............ 314
HC 136 ............. 36
CO% 0.76 .............0.01

 

Were those cruise readings or idle readings. Those look just like my cruise readings, but my idle readings were through the roof.

 

guess i'm not really sure if those readings are at idle or with the wheels rolling on the dyno, although I would believe it has to pass at both idle and when moving. Now that I checked the printout they gave me it says rpm's are 0.

when i had my Grand Cherokee tested last week, it had the rpm's listed as 2500 on the printout.

All I know is that I was very pleased that it did pass!

 

my FD passed state inspection at a state inspection station. the morons stalled it a bunch of times. With similar mods except 87k mile blown coolant seal engine and smoking. i passed with flying colors 1/4 of the maximums for everything. you just need a cat and air pump! congrats
