Biggest Cam & Still pass e-test?
 

Would anyone know what is the biggest cam I could run, and still pass an e-test in Ontario? Besides an FMS E303. Thanks.

Welcome aboard and one of the experts will be along momentarily. Good luck with your project!

1LOW03GT ...... over to you.

E303 or B303. If you look at the Ford racing catalogue I believe those are the only two emission certified cams.

small choice for sure. Move out here no e-tests lol

^^^^ Gods country!

Mine has a b303, passed fine at 40 roll, at idle wasn't even close, way too much fuel. car has heads/cam(obv)/intake, no pollution pump and mac shorties. Possible to pass at idle with tuning? Sorry to high-jack thread but this may help you too.

retry your test, but pull the spout connector just before it goes in, and add 3 liters of methyl hydrate. garauntee you will pass the next test that way.:shakeit:

Spout connector? Sorry Im abit of a newbie. Yes have heard about methyl hydrate though. Thanks for your time. Hope this is helping original poster too.

yes it is that little dead end plug that is attached to your distributor:

Attachment 15020

See the plug in the blue square? unplug that little gray thing in the end of it. what that does is prevent the computer from advancing the timing, which will lower you emmisions by a ton.

^^^very helpful to the guys and thanks. Are there not parts of Ont were e-tests are not required????

E-tests are required everywhere in ontario as far as I know. Which for a vehicle insured as a classic and driven less then 5k a year I believe is ridiculous. Theres always the "know a mechanic" etest though, or for foxbodies the fact that cars 87 and older dont need to have etests, last time i looked 87-93s look pretty similar....
I didnt know of this plug, although my timing was initialy advanced and we set it back to stock. So will removing this plug create better results then stock timing with plug not removed? Thanks.

yes because with the connector still plugged in, your computer will add timming as the e test is done. especially during the cruising part.

etests are not required in all of ontario... in northern ontario, towns are small and far apart so basically anything north of barrie doesnt require an etest, its a glitch in the system but understandable considering people who live up north would have to travel hours to get to a drive clean facility. so if you love modern muscle cars, move up north, cause you can tinker with your cars without having to worry about your emissions system.

I live in Barrie. Looks like I should have moved a mere 10 km North. The 10 km would have been worth no more e-tests.
