Smog delete June 24, 2014, 02:54:19 PM Hi all,I assume someone has done a smog delete on an EFI 5.0 here. I have a dummy pulley to put in place of the thermactor (air pump). But what else can I take off?Thanks,Kyle Quote Selected
Smog delete Reply #1 – June 24, 2014, 06:00:20 PM You don't even need a delete kit.there is a smog on the back of each head. all the 5/8" ish rubber tubes, and the metal tube that connects to the cats. Quote Selected
Smog delete Reply #2 – June 24, 2014, 10:13:25 PM I haven't done this yet but can't you just leave the smog pump in place and short belt it? Quote Selected

Smog delete Reply #4 – June 25, 2014, 08:53:50 AM okay, so pretty much everything connected to the smog pump can be removed? Theres also a small black box on the passenger side in the engine bay. I think its a carbon canister of a sort. Do I need that? And as it is, my EGR valve has its vacuum plugged. So my EGR is "off" for lack of a better word. Quote Selected
Smog delete Reply #5 – June 25, 2014, 01:52:54 PM Leave that black box. it keeps gas fumes from smelling up the car and making it seem like you have a gas leak.egr, id just leave there unless your going to remove the spacer, but if you do, you'll need a new way to mount your throttle cable.

Smog delete Reply #7 – June 27, 2014, 02:00:29 AM There's no point to deleteing it anyways. it gets shut off at wot and is nothing more then a free spinning pulley anyways. I've bypassed mine when i had it lock up on me and a belt was easier to get then a smog pump at 2am. Quote Selected

I've bypassed mine when i had it lock up on me and a belt was easier to get then a smog pump at 2am.Sorry, I'm not sure what "wot" means. I still have my pump on and it's working. Short belting the pump to pick up a little HP is something I had planned on at some point. Is there a way to make the pump just a free spinning pully while the belt is on it? Quote Selected
Smog delete Reply #9 – June 27, 2014, 09:53:00 AM WOT is "wideopen throttle".... not to be confused with "bwahhhh!" which is the sound your car makes at wide openAnd yeah, I was looking to save a few horses, shed weight, eliminate a load on the engine blah blah blah. But also, If i go to aftermarket headers/midpipe they prob wouldnt have "ports" for the smog pump to blow air into, right? Quote Selected
Smog delete Reply #10 – June 27, 2014, 11:14:11 AM You can fabricate or buy EGR blockoff plates. Here's one: http://www.ebay.com/itm/like/151307667010?lpid=82 I bought a smog pump delete kit for like $20 online somewhere...had a brand new serpentine belt so I figured that was about as cheap as buying a new belt. In the end it really doesn't gain much as far as HP goes. Quote Selected
