86 mustan GT with a blower

I'm going to look at a 86 mustang GT with a blower? or mabey a super charger? Ii won't pass colorado emmison test. do I need to reprogram the computer on it or what? I have never played with a blower or super charger what is the differance between the two. He said it runs and drives good.
he said he would take 350.00 for it he was asking way more for it but no bites on it. what do I need to look for.

Most people, don't know/ recognize the difference and use the terms interchangeably. However, to me a "Blower" is reserved for something like a GMC or similar unit that bolts on top of an engine and draws air thru the induction system. A supercharger usually compresses the air, before it the induction system.

Of course, that that most cars are fuel injected, like the latest Ford mustangs and the older V-6 Thunderbirds, most of that difference is no longer important.

Practically, the term I seem to see most ... the centrifugal units (Vortech, Power dyne, Paxton, etc.) are called superchargers; the engine mounted units are usually called blowers, except the factory installed units which are called anything at any time by anybody.

The way things are now, just make up your own definition. No one seems to want rules or hard definitions; just call it a power adder?

your right I think this one is bolted to front of the block. I'm going to see the mustang in the morning
thank you

I got the mustang home today. It has a Vortech V-1 supercharger in the hatch, but all the mounting brackets are on the engine,the fmu is on the the tower hooked up. it looks like they put on a hp kit with the cpu unit to add the mass air sensor to it. but the paper work says the kit is for a 87 mustang with mannual trans. the stang is a auto aod four speed. any help you can give me would be great. can I put the stock cpu back in it? I would like to keep it in street form and run it at the drag now and a gain

I really hate to get into the middle of 1/2 finished projects - you never know why the original guy lost interest. Could have gotten in over his head, broke something, lost something...you never know.

As far as help, I'm not that good with superchargers, the last one I installed and ran was ball-bearing Paxton. Then newer units can pump out some pretty potent numbers. I would suggest putting the unit together as is first, see if all the parts are there - see how it runs, before modifying things.

A stock AOD is not the strongest automatic that ford ever made. I'm thinking if the supercharger is half way right, you'll be upgrading it in short order. The good thing is a properly prepped aod is not that bad, and the Overdrive can save you a lot of gas.

Get your tools out, get the manuals and start wrenching. When you run into problems.... and you will ..... just give a holler, me or somebody else should jump in with the best advice we can come up with.

Do yourself a favor - take pictures and keep notes on everything you do, they will come in handy later on.

With the low power superchargers, under5 -8 lbs, sometimes you can get away with the factory computer, for a while ... but the FMU will be needed to pump in extra fuel when that supercharger start to wind up. You will need extra fuel volume too, did the owner add an aux. fuel pump or drop the tank, install a 255 + unit or both? Once the supercharger gets above approx. 8lbs boost, you risk running out of fuel at the top end.

Like I said, when you take on a 1/2 finished project, there are more unanswered questions than you can believe if you haven't been down that road before.

thank you I will get into it and see what happens. how would C4 work in it
