the Aluminum Monster. a 318 with a special 24v

well... not the results anyone wants to see. Failed again, and it was actually worse this time. I drove the car hard on the way, but arrived early and decided I would leave the car running while I waited. Idled for probably 15-20 minutes before he finally started the test. I'll let the pics tell the rest.

Waiting


And rolling

Bummer! Hang in there Simon. The cat should make a YUGE difference. You'll get there!

I don't know much about smog testing equipment but it's really strange to me how much the numbers change between 15/25 mph. The mandated amount is basically the same, but what comes out the tailpipe can be 10-20 times different by switching between the two speeds? Worries me cause mine shoot out near nothing like yours did on a few tests, but maybe just a little random thing can shoot it way over the max.

Hope the new cat gets you through!

bummer about the smogging brotha.

On the other hand, your car looks fantastic. That rear valance/muffler you got going on gives me a good amount of chub.

Man that sucks, I almost feel bad complaining about state inspections now.

How are your cats? Sorry if I missed this earlier, but since you're running a mostly-stock motor it should pass, right?

The S50 cats that are on the car now are estimated to be at 150k based off the mileage Ive added to them since i bought them. Im contemplating buying the magnaflow CA legal cats (which Ive read only last until the next time they need to be tested) and buying another set of S50 cats which are estimated to be at 60k. I would think the OEM cats are made to last much longer than an aftermarket cat, so Im leaning that way.

Im more excited about the fact that I will also have the supersprint muffler installed at the same time as the new cats

Bummer. Ryan used Walker cats and passed with flying unicorn farts when he went through BAR. This was after failing with Mangaflow(?) cats.

[2mAn]

Ive been researching and I like the Walker cats better because its two single converters and I remember digger playing with placement of the cats on his car and it looks like offsetting them made the most power, so Im thinking about doing the same. In addition to that, they have a 5 year 50k mile warranty, which should cover me for two more smog checks

Fresh cats will make all the difference you need. Aside from the cost of the cats and installation, passing your next SMOG test should be a cakewalk.

I failed with new Catco cats, installed by Castro's at the time.

Turns out the manufacture recalled all cats and my defective ones were part of the recall. I ended up going with the more expensive Walker cats, but they worked as intended and made everything pretty again.

I even made a thread on it. Here, I dug it up just for you: http://www.r3vlimited.com/board/showthread.php?t=264592

sup Simon. Letting the car idle for 15-20 minutes let the stock cats you have cool way down. If possible for next time you need to make an appointment drive it really hard and drive right on to the rollers and perform the smog test.

Thanks for doing that!

Hey Alex, I knew letting it sit for so long wasnt good. I tried to time it so that the car wouldnt be sitting for so long, but I always seem to have to wait with him. I think Im still going to pick up the lower mileage cat from the forum member and swap that in and see what happens.

If that doesnt work he said I wouldnt have to pay him for it, so I would just be out the cost to install it and though I can do most of it myself at this point I just want it done.

Do they charge you if it doesn't pass? If not, just keep going back until you get in a slot where you don't have to wait/idle.

[2mAn]

They dont charge, but the referee station is only open during the week and each time I go, Im losing at least an hour of work so its hard to keep scheduling appts, though my last appt was at 8am and I thought I got the first slot, but someone else was already there so I need to try and get a 7:30am slot or something.
