That's a pile easier than stuffing in a 1500 sp for the test.....Nice job!
-
right on jim. :rockon: i cant wait to see that car tear up the 1/4.
this is one case where it is ok to be below average. ;)

Hope to see the Wok on the AC top 20... Maybe you passed cuz you had that little green man in the rear

Ummmmm well never mind that one's just way to easy..... :P

Holy Jim !!!! .... wasn't it just like ..........yesterday you had your motor
all a part?? What lifter/ cam combo did you have before?
What did you go with now?

Welcome to the \"passing aircare with big engines\" club Jim. Your results would have even passed the specs for my year (75)
Go to this link to see my results:

and enter my VIN, 1152021716

You might wanna take tha last secure spot on the Dyno...

Good job Jim!! So what cam is in there?? the 48Dells are great carbs for tuning.
Many years ago I went through with a 2110 with W125 cam with 44 idfs. Back then I had a tough time getting the 48 Dells to pass. That was back when CIP was on McPherson. From that time and now I've learned a whole lot more \"making\" things pass.
I've had 1600's that looked perfect on a calibrated 4 gas analyser fail at aircare. Flat4's seems to be more unstable from the time at the shop and when on the dyno. I've had POS cars with tired V8 motors look great on the 4gas and retain its same level of emissions at aircare. I think its probably due to watercooled being more stable in operating temps.
I had an 1500 single port look phenominal in one car and then when installed in another car over a period of time the emission levels changed from a beautiful pass to a horrible rich pig that woulda failed 100% This is with just sitting and the carbs mixture screws untouched.
So what a/f ratio did you get on the LM1 to achieve that CO% ?? 13.xx:1???
Good job man!!
-
these results are from my 2275/94 pump gas/10.1 comp/86c@1.4 rockers.
engine as tested is 100% as it will run on the street .there is no 'tricks' or 'gimicks' to make it pass.just a good state of tune coupled with a mechanically sound motor.
now i can't give away all my tuning secrets,i guys's got to have something under his belt . Alan , lambda is your friend :D
next time we bump into each other we can chew the aircare fat.
whats also funny is that the guys at the kent aircare station seamed to be trying everthing in order to make it fail or give a reason not to test it but,thats a whole story in itself.
the best was whan i was sitting at the end waiting for my test data sheet and the guy had the what to do if you fail info booklet in his hand,he had to do a double take at the data sheet when it printed
-
Good Job Jim, Nice to see you passed with the 86c :rockon:
-
Excellent job Jim! Those LM1s are awesome!
Gary.

what`s an lm1 :blink: i need some serious aircare help!
-
what`s an lm1
Hi leadfoot,
LM1 is an air-fuel ratio meter. Read more about it HERE. (http://www.innovatemotorsports.com/products/lm1.php)
Air Speed Parts sells them.

kinda been pushing my luck with having my beetle regi`d on the island. i take it u gotta drill a hole in yer exhaust, weld in an o2 bung? then come up with $400.... check out my previous attempts at aircare vin# 117689413. yeah, these are the ones that i had to pay for... everytime i look at this i get angry :angry: :angry: :angry: :angry: :angry:

If a gas-hogging Lincoln Navigator can pass aircare and a bug can't, no matter what size engine, there's something wrong. Not to mention the fact that more pollution was created in the manufacture of one of these big new gas hogs than one of our little cars has put out in all the years since it was new!

My ghia has a 1600 motor. It's pretty much original I think. What are the chances I will pass aircare? The car has lots of miles on it, but a mechanic said the motor was in good condition? Can anyone tell me, or point me to a resource that tells what tuning needs to be done to pass this aircare? Would it help to use a engine additive like stp? What about using Mohawk gas? Does the aircare for these old motors require very strict standards? I thought they were nicer to old cars.... Also, I don't understand, am I supposed to use 92 gas not 87 regular in this old VW motor? The old paperwork seemed to require 92 octane? Is that because it was designed for leaded gas originally? Would that make the emissions lower? Oh, and my car has the original carberator. My dad says it looks \"primitive\". It's a \"solex\" I think. I mean, it works. How hard it it to \"rebuild\" one of these things? How can you tell I don't work in the industry. Thanks, Steve. (xcasper) PS, I love my ghia.
-
Steve, are you gonna drive that thing?
If the engine is all stock, and in good condition, and adjusted properly, it will breeze through aircare. You don't need to resort to any funny business to get it to pass.
Use only 87 octane. The way gas is measured today is different than 30 years ago. Today's 87 octane is more than sufficient for your engine.
Steve, you should take the stock carb apart and rebuild it. That's one of the rites of initiation into the VW world. Just make sure you have the orange Bentley manual in front of you. Airspeed sells them.
-

Steve! I'm curious, too!
Is this the same Ghia that Bruce, Silas, and I looked at?
Or another one?
-
Hey, be nice guys. I don't make fun of your buggies. Yup, my roadkill. I am talking the long term. Car is parked right now... \"Some\" of it will make it on the road. Thanks for the gas info Bruce! -X- :wacko:

O.k. I got one for you guys I took a t-3 through air care to day . I leaned it out the best I could reset the timing to where it should be .they said they couldnt get a reading at all on the Idle .No pass no fail :huh: . And they said I had a major exaust leak :wacko: . Which it doesn't any thought's on this . Thanks in advance
It's a 1600 with tiny dual carbs
-
Rusty , I had this happen with our old 72 bus with stock carbs 1700cc. It seems I adjusted the mixture screws a little to much (in or lean). They told me all the same things , can't get a reading .... must have an exhuast leak BLA BLA bla....... I went right back around and got back in the line up , backed out the mixture screws maybe 1/8th of a turn......BINGO , passed with ease.
Anyone else have some ideas?
-
What is usually happening is that since our tail pipes are very short, their probes don't fit very far up the tail pipe. Due to the natural pulses of the engine, air will be drawn in from the end of the pipe. Their sensors pick this up as a dilution error. Too much dilution and they can't get accurate readings so they kick you out.
If you know you don't have an exhaust leak, tell them to better seal the probe to the tail pipe. They can add a rubber extension hose to your tail pipe after they stick the probe in.

Those guys at the Kent station were acting as if I had brought in a foreign flying space ship. They needed help to find the id#; they asked me over and over if it was automatic. The guy stated the test on reverse and I stopped him.
I was expecting a certain level of expertise.
But it is great to hear that big engines can pass it too.

I watch for that too. But since my car \"fast passes\", they already know it passed before it's off the dyno.
