hey guys ive been reading these forums for a wile and some of you guys seem to know your ****. I own an realy clean 89 iroc 5.7 tpi its got slp cat back with no cat modified mass air flow sensor air foil 8.8mm wires accel ignition hot water throttle body bypass, that it for now but my question is i am considering rremoving my smog pump for more horse and a cleaner engine compartment. I read the article in the tec data page. Is it worth it in terms of horsepower and if so what do you yhink the gains would be any responce would be apreciated.

 

you wont see much hp gain but you clean up your engine bay and shave off like 15 lbs

 

yea thats what i thought.have you actually done this.

 

yes i have it was quite simple

 

how did you remove the pipe behind the block that connects both manifold exhaust pick-ups?

 

That pipe is a bitch and a half to remove. It's inflexible and goes all the way to the cat so you basically have to "permanently" remove it (ie hack off pieces of it to snake it out). You might be able to remove it whole but I'm telling you in advance it'll be a royal pain in the ***. You'll never want to put that AIR back in the car once its out....trust me. Ditch it and be done with it. It GREATLY cleans up the engine bay and takes off a couple pounds (not to mention a belt if you are a V-belter).

 

i took my air stuff off! very easy took me about an hour..

i actually wiggled the top of the air tube off from behind the block..

i actually beat a camaro that usually beats me by about a half a car..

i did a 180 stat, a/c delete, and removed the a.i.r stuff...

 

dude........that was a haiku.....

 

yea all my air pump stuff is off just not those 2 pipes. I have them cut so I can get my valve covers off. Yea once I get running I think I'm going to go up from under the car and hack it out!!
