All I wanna make sure is my no A/C having wanna be car falls in the "mega power" category?
Then I will sleep well at night.

Just by removing your AC automatically results in you having MEGA HP. However, in doing so, people will become very jealous.
This reminds me of Jeeps. All of the over the top stuff that people do to Jeeps that never leave the pavement. Saw a bumper sticker on one that said " It's a Jeep thing, you wouldn't understand" Your right, I don't understand it. Foxbody guys need a similar bumper sticker. "It's a FoxBody thing, you wouldn't understand"
The guy I bought my car from not only removed the A/C (black on black coupe....ughhhh), but went one step more stupid and removed all of the smog equipment as well.
The car is so much nicer to drive now with all of that back in place....and guess what....it didn't make a lick of difference to the performance.....and I can actually drive around without getting a headache from the exhaust fumes now.
...still rides like a lumber wagon though, but I'm blaming more of that on the
ty Northern Ontario roads than anything.

I believe the removal of smog equipment to be more about cleaning up the engine bay than the imaginary HP gains. Or something stops working and they don't want to pay to replace it so they remove it. I'll be removing my smug pump and tab/tad soon and going with an o/r h-pipe. I've never had an exhaust smell inside the car but maybe I'm just lucky and some aren't.
I don't know if it was you or @Noobz347 that made a comment a while back about this kind of stuff but the comment went something like "i've realized that I can have my A/C and still stomp the occasional car at a red light"

Yeah.... the "cleaning up the engine bay" excuse is used a lot. Unfortunately, it really doesn't fly when I see rusted hardware, rotten rubber and the gangly, cracked, dirty wires strewn all over the engine compartment, buried under 20-years of crud/rust and illuminated by light shining through 50-60 factory drilled holes belonging to various fox vehicles that are drilled throughout a set of scratched and rusted strut towers and inner fender skirts.
As far as replacing or repairing....I paid $20 for my smog stuff....most of which you can find for free, because the last dimwit pulled it off thinking he's freeing up all kinds of power.....or that it actually made a difference cleaning up his engine bay.
If it ain't a show car, leave it alone....because to the rest of us, it doesn't' look any cleaner, it stinks and it opens up the door for a host of problems.
A 5.0 without cats may smell just a tad bit worse that one with them but not by much. My old 88' LX didn't stink while driving in the car or stopped in traffic. The only time I smelled it was while standing behind the car while it was idling which is obviously normal.
Also, what host of problems (mechanically) comes from removing cats and the smog pump system?
As someone who just swapped out his O/R X-pipe, for a catted H-pipe, I'll have to whole heartedly disagree with you on that one. The difference in air quality between cats and no cats is VAST!!! To say it isn't, is just down right ignorant and silly. And that's not just at idle either. My car reeked of exhaust fumes at all times with the O/R mid-pipe on and is now barely noticeable....and even then only during cold start.
Removing the smog equipment is going to set off alarm bells with the ECU. At the very least, you'll immediately get a 44/94 code that you can't get rid of unless you pony up several hundred dollars for an ECU tune. You've also now got to deal with items like the EGR, IAC, and, PCV sticking and failing randomly, because of the dirtier environment they're now in. Mileage goes down, emmisions go up, oil gets dirtier, more quickly, carbon deposits in combustion chambers and around valves increase....which causes pre-ignition and detonation issues that in turn increases combustion temps, necessitating the need to reduce ignition timing....harming performance.
And then we've got driveability. Your O2's will get dirtier, sooner, causing them to not only fail sooner, but to in the mean time slow in their reaction and performance, making their operation less consistent. Idle quality can suffer because the other sensors are now not operating at a consistent regularity and the computer starts not knowing which end is up? But don't worry.....this probably won't all happen at once. It'll likely plague with with random issues over time, so you're constantly trying to fix one problem after another with the car. It'll certainly keep you wrenching under the hood, if that's what you like to do.
But hey, at least you got rid of that nasty smog pump located at the very bottom of the engine, that's hidden by the other accessories and intake tubing that you barely see anyway, right.
Do yourself a favour....hide you wires and spiff up the rest of the engine compartment and leave your smog equipment right where it is. You want a little more performance, swap out the stock pullies for a set of underdrives and factory mid-pipe for an after market high flow catted unit and call it a day. You'll get more from that than you will bastardizing the stock smog system.
Why pray tell is that? I've been using them for almost two decades, on various Fox bodies.....no issues, what so ever. Probably the best "bang for the buck" mod out there for a Fox.
Of course, one of the first things I've ever done to all of my Fox bodies, was upgrade to a 3G alternator.....and then I overdrive them on top of that.
I would NOT recommend a person use underdrive pulleys without doing so....but then again, I would NOT recommend someone keep their stock alternator in place either. The stock 75A unit was less than adequate for a bone stock car. Own an A/C car, with full accessories and that little sucker doesn't know what to do with itself. Throw a half decent stereo system into the mix and they're done.
I tried to maintain the most street car aspect I could in mine for these reasons . It's as quiet as it gets for long tubes and a x pipe so I lose there ... But Full stereo . Ac is on its way to being all brand new .

My smog pump, egr, cats, etc are not missed a bit... and my megasquirt doesn't miss them either.

PCV has nothing to do with catalytic converters, it vents crank case pressure back into the TB. Cats only clean up the exhaust fumes from the cats back to the exhaust tips and that's all. The "cleaner" air from the cats do not recirculate back into our engine. The EGR gets it's air from the heads (not the h-pipe) and pumps it back into the engine via EGR spacer, not the throttle body which is where the IAC is located. I've never have had a problem with my O2's crapping out but maybe I didn't keep my car long enough for them to fail as a direct result of no cats.
Thank you for all your doom and gloom over removing a smog pump and cats but I'm not buying it. Yes I agree the air is a little dirtier but BFD. If that's the argument then why should I even own a Mustang as a toy? Shouldn't I sell it and hug a tree and in my spare time slash diesel truck tires and key "gas guzzler" on the side of hummers and excursions?
@Boosted92LX
Your MS and my PiMP don't look for smog equipment so smog related CEL's and codes don't apply to us as you just stated
You answered the question there. And down here, the underdriven waterpump is a poor idea with 100°+ heat indexes.

fwiw,. i've removed the smog equipment on every fox body I've owned. Wonder how we all survived growing up before all this smog stuff was thrown on cars..lol
I'll start worrying about all the terrible exhaust fumes my tuned car emits when Al Gore stops flying private jets.
