    With the 4R70W gears in the AOD, it's even more pronounced. 1st gear is a good deal lower than the AOD. I would like to have a 4r70W put in my 93... but I have no real desire to any more.

      Oh, you can do that? Neat. Is the 4R70W's OD ratio steeper than an AOD's?

        slightly shallower actually, 0.67 for the AOD vs 0.70 for the 4R70w.

          yeah. 3 and 4 are basically the same. it's 1 and 2 that are a good deal lower than the older ones.

            EGR delete and no cats, air pump dual exhaust all help. Non ethanol gas helps. Replace the OE nylon over aluminium eingle row timing set with double row set

              Keep the catalytic converters. The rest of us will thank you. Nothing like getting stuck behind a mechanical asshole and then stinking as a consequence. Not all of us have the luxury of cabin filters.

                honestly the EGR doesn't cause problems if its working as designed either.

                the air pump in theory shouldn't hurt, but in reality it doesn't do much of use either, it makes stupid noises when working and really stupid ones when it fails.

                  smog pump that was on the 88 MGM I had sounded like a turbo when it was failing before it seized up. Was kinda neat for those two weeks.

                    one of mine sounded like a drunk with a maraca, the other sounded like a flying saucer in a cheesy sci-fi movie from the 50s.

                      I never noticed any sound from the smog pump on my ‘88 Grand Marquis. The one on the Mark VI sounds like a coffee can full of rocks on startup, it goes away as the engine warms up. Eventually it’ll probably seize up, at that point I’ll remove the entire ordeal. Until then I’ll likely be too lazy. I’ve had the belt off and it turns freely and there doesn’t seem to be excessive endplay in the thing so I don’t know what it’s issue is.

                        Smog pump has never been an issue on my friend's car so as long as that is true, it stays because "why poke the bear".

                          That's the general idea for me and engine stuff for the most part. I do monkey with the intake and cooling though.

                            good ones aren't terribly noisy but they do tend to make a bit of a buzz/fart kind of noise, especially when its in bypass mode and just dumping to atmosphere.

                                When the bearings went out on mine, it started to make the worst ear-splitting whine-squeal I've ever witnessed to come from an automobile.
                                If it hadn't done that (and thrown the belt), I would've left it be.

                                I'd bet the biggest performance gain from emissions equipment deletes is the weight reduction...
                                Except in my case, the EGR went apeshit and made the car run like crap.
                                And I'm defo keeping my cats, because I don't like to SMELL BAD.
