Getting rid of the smog pump. EBL Flash doesn't support the A.I.R. system, so since it isn't being used, I'm getting rid of all that piping too. I can use the diverter valve solenoid connectors to turn cooling fan on/off with a little reprogramming of the code words.

Do some research. IIRC you don't need a pulley for that. You need a shorter belt and to route it differently. You need an A/C delete pulley if you ditch the a/c.

Thanks Paul, I actually thought about that after making the post.

6 rib, ~96.6" belt?

I am pretty sure you need a longer best because of how its re-routed. The number Ian mentioned sounds familiar.

I'll also add....if you wanted to keep it, you should be able to make sure that it always flows to the Cat instead of the air tubes, then it should have no effect on o2 readings, but will help keep combustion temp of the cat up. If you run a cat, it might not be a bad idea, in theory the extra air should help the cat stay clean and not get clogged up nearly as fast.

I don't see why not.

Because the smog pump is only on when it's cold/warm up. I remember somewhere in my training you don't want/need full time air to the cat.

I thought the diverted pumped air into the exhaust manifolds during warm-up, then diverted the air to the cat after it warmed up.

It's been a LONG time since I've played with one that had it's emissions garb on it. I thought I remembered the large lines were connected, pumped air into both?

Lots of cats are run without an air injection. I'd ditch the pump etc all together, and use that circuit for your fans :O)
