March 11, 2007looking for a way to elinate the smog pump on my 5.o with out adding the elinator pully
March 11, 2007Use a shorter belt. Part #6pk1805 or 710k6 These are for non a/c 5.0's
Anything to do with Mustangs ANYTHING!
March 12, 2007Mine just has the hoses to the smog pump removed and the smog pulley by-passed. I wouldn't do it, mine wouldn't be done if it already hadn't been. If I'm not mistaken, 5.0's are carbon machines, they produce a lot of it, and without the smog, this gets shuffled through the exhaust. Gives a funny oder. I don't mind it, but my wife hates it. Of course my car has dumps and that make it 10x worse. I'll prolly leave mine off, due to the pump is more than likely seized, and just run the exhaust the rest of the way out the back. I can't wait until I can afford it. I have the cobra bumper, and with LX stainless steel exhaust pipes..... I'm off topic again.
March 12, 2007A shorter belt will do it but don't expect to put the longer belt back on for smog checks. When the pump is not being driven it tends to get moisture in it and freezes up. In addition it only takes about 2 HP to drive it so don't expect any big gains from its removal.
The best reason for its removal in a state where smog is not checked is to clean up the engine bay over there on the right side and make the spark plugs *much* easier to get to. The tube down to just after the cats needs to be cut and plugged somehow in addition to plugging the ports on the back of the head. If I remember correctly You can pull the pipe off the back of the head, turn it around and put it back on which effectively seals the port in the head.
March 12, 2007When you bypass the pump without disconnecting the lines from the heads, the hot air and carbon eventually cause the pump to seize due to soot buildup. If it doesn't seize it might just squeak in an amazingly loud and annoying way.
Like BB said - 5.0's ARE carbon machines. The reason for this is is mainly due to the way they were tuned, stock - the late '80's ones are SO rich from the factory that there's power left on the table due to running too rich at WOT, and you get all kinds of soot buildup that can even clog/kill the cats.
I wonder if your strange odor is rotten egg-like? If so, it means your cat's are working, and there's a lot of sulpher (sp?) in your fuel. Annoying but harmless. If it smells like an OLD car (various gasoline like smells) then I'd guess that your cats are not working, either due to being depleted from age, or else dead from the car running too rich too long, and heat causing the internals to melt into a lump. If that's the case you'd get more power if you replaced them, since they're blocking your exhaust partially right now.
March 13, 2007So-Cal,
You old car. Smells like my brother's old 65 he used to have. I guess that could be due to NO CATS and NO SMOG. It's only magnified by the dumps. I'm hoping to get the exhaust ran out the back to minimize some of the odor.
So-Cal, you have mail.
