ok guys... i am working on my truck right now and rebuilding the top end...

and now that i ran into some issues im gonna delete some stuff while i got the time...

what all can i delete as far as the smog stuff go?

do i just disconnect the smog pump and plug the lines? or what?

also, whats yalls thoughts on putting a smaller belt on to also bypass the A/C for the fall, winter, and spring.... and then in the summer time pop the belt back on and have my Air conditioning back....

i need some tips...

 

Removing the smog pump will gain something on the order of 1/2 HP and will cause the cats to fail prematurely. Removing or disabling the EGR system will gain zero HP and will increase fuel consumption. The emissions stuff is pretty well integrated into the EFI and removing it is ill-advised

 

It's also illegal, and discussion of illegal activities is prohibited by the user agreement on this forum (and most others). Read this article.

 

And the A/C cycles when you are not using it to keep the system working.

 

Another thing you might want to know, the A/C dehumidifier is used in the defrost setting. Therefore, bypassing ther A/C compressor may lead to foggy windows for a long time on a cold, humid morning.

And as for the smog pump and EGR valve: Welcome to the second decade of the 21st century, Rip Van Winkle !!! How was that 30 plus year sleep? Cure your insomnia? Yes, in the '70s and '80s smog equipment received a bad rap, but that was before people really understood these systems, and before computer controlled EFI used these systems to operate properly. Honestly, you may lose 5 HP AT MOST in parasitic losses with this system installed, however, you reduce vehicle emission greatly with these pieces installed and operating properly.

The ONLY way I would have a newer vehicle with an A/C bypass is a drag racing only vehicle that never sees the street. And there is no way I would ever remove smog equipment. I believe that is a violation of federal law if you are found to be without factory emission equipment on your vehicle.

 

Actually you sir, are wrong.. There is ABSOLUTELY NOTHING illegal about removing EGR, SMOG, etc etc from a vehicle. Therefor it is not against the rule sets of this, or any other website.

The activity that is illegal is driving on public streets.

 

Wow! Did you manage to pick alot of fly poop out of that pepper? Of course the guy intends to drive it on the street, and even if he didn't it encourages others to try it. Just drop it, if it isn't right-then it isn't right. SHEES!!!!

 

...and it's still illegal to remove it, even if you never drive on another public street.

 

Ain't nuthin illegal till one gets caught

 

That is a REAL mature point of this argument. IMO getting caught has nothing to do with it. Fact is the truck was designed to use a smog pump. The computer was programmed the same way. You can't simply remove one part without affecting others.

 

Wow you should post this in the exhaust forum . Pages and pages or removing all or some Cats.

To the Op dont think it is worth removing all your emissions under the hood for MAYBE 2hp

 

It is not illegal to modify your emissions of a vehicle if its used for off road use only. He hasnt specified whether it is or not for road use. And to tell him that its illegal for on road use is fine.

But to accuse him is another. You have no idea what he is doing with it. Dont assume. Makes an @$$ outta you.

Honestly though, its not worth it as far as removing pullies for hp.

 

"ain't nuthin illegal till one gets caught" is more a statement of fact than an argument.

The intelligence and judgement used in making such a decision is more a topic for discussion. Is there a legitimate reason for removing all of the smog equipment? Probably not, but the question was valid, regardless of intent.

 

boohoo... you dont know if im turning my truck into a drag truck only...



so i could really make you look like an ***...

but anyways. i dont care if it is illegal or not.. theres plent of threads that are talking bout removing catalytic converters... and guess what... thats illegal too...

why dont you move on somewhere else...

 

You're the only *** around here. You asked a question, you got an accurate answer. If you don't like it, you don't need to smart off. You can either take or ignore the advice as you choose but you don't get to run your mouth. As for your comment about moving on somewhere else, look at Steve's post count and look at yours. Who would you say contributes more to this forum?
