First of all, the kit is available from various sources. I've seen it in Summit, Internet Racer's Supply (my personal favorite), or direct from Powerdyne. Because part numbers vary depending on your dealer, it's the 93-97 Camaro Z28/Trans Am 4.5 PSI Satin kit, runs about $2400 + tax. Comes with brackets, ducting, blower, and FMU.

The Powerdyne is the best option for fabbing on for a few reasons. It's low boost. 4.5 PSI on a 350 translates to 5-7 PSI on a 2.8 I've been told. I haven't run the math myself, so someone might want to correct me on that. Because the smaller displacement will essentially increase boost, you don't want to start with a 9 lb Procharger system and finish with a mushroom cloud. Also, Powerdyne doesn't need/use an intercooler, or oil lines.

The first thing you'll need to do is ditch your A/C. We in the V6 world are used to making sacrifices for speed, so this shouldn't be a problem. Keep the brackets though. Next, by either installing a flange of some sort on the blower itself (cut some thick gauge sheet metal, possibly even a few layers, and make a 1 inch bolt-on flange for the blower), or by using flat stock steel to make adapters for the A/C brackets (1" x however long you need, drilling a hole in each end, attach one end to the bracket, the other to the blower. May have to countersink into the flatstock for clearence issues), install the blower onto the A/C brackets. You may even have to cut up the brackets that came with the kit for spacers.

I don't know which method will work best, because I've never had the unit in my hand to check.

Now the FMU. In theory, the FMU will compensate for the blower in the fuel system, but I'd still consider getting a custom chip if I were you, and possibly a V8 fuel pump (is there a difference? Never gotten a straight answer...). You may have to use a variety of adapters, but the FMU should be, as intended, a plug-and-play deal.

The crank pulley just might be able to fit on without any adaptation, but I doubt we'll be that lucky. May have to drill the pulley, may have to fab adapters for your crank. Either way, the belt probably will not fit, so count on finding a place to get an odd-ball sized one.

Finally, the ducting. IF you have a MAF sensor, you may have to get creative. If you're running on MAP, you can be dull. Either way, this part is not rocket science. The air goes from the blower, through your MAF (if you have one), into your throttle body. Got it? Good...

Once you have all this done, start the car, do all the checking that is necessary, take it for a ride (easy killer, you'll bald your one-legger tire real quick if you're not careful), and then come home and get a good night's sleep. The next morning, go on a road trip to St. Charles, IL, whipping V8 cars all the way, to show GMI Fast that it can be done for little over the price of the blower itself. Counting chip, about $200-300 extra.


I plan on knowing if all this works in the next 2 years (I know, I know, but I'm in college for another year, and I'll have a few too many bills to be playing with the 'bird when I first get out).

I might be forgetting something, as I'm under the heavy influence of NyQuil right now, so if there's any obvious flaws, let me know.

Thanks for the info.!

 

sounds good except the bracket part i think i would have something nice i dought i would just cut out sheet metal for brackets but otherwise sounds like a plan id prob ,only do a turbo charger with a rebuild.like i said sounds good.

 

"The next morning, go on a road trip to St. Charles, IL, whipping V8 cars all the way, to show GMI Fast that it can be done for little over the price of the blower itself."

No kidding. ANYTHING can be done if you are willing to fabricate needed parts. We have a 10-second Neon, for God's sake. As far as pricing goes, extra money required to bolt on a supercharger is a LOT less than money needed to fabricate a custom turbosystem. Good luck with whatever you decide.

Oh, and just hope that one of those V8 cars you come across on your road trip to St.Charles isn't mine...

Reno, are you sure you really want to run 7-8 psi, I would keep it 4-4.5 psi, but thats just me.

And yes, hooking the blower up and fabbing parts isnt going to take a genius, but you will need the tools, piping and metal to hook everything up.

The tricky part would be getting the motor running correctly with the blower installed, but I;ve been told by several people as long as the boost isnt real high, the stock ecm should work fine.

 

In response to GMI;s offer to watch him at gateway, nah, watching spew cars oil down the track gets old.

Reno, how much does the powerdyne unit weigh?

Will you two hose eachother down elsewhere? this is not intended to start a flamewar. As for boost pressure, the smallest one I can find is 4.5, and it would go higher on a smaller displacement block, but I'm also considering a blowoff valve to keep it low at first.

Good point Reno..

Lets cut the flameing already.. I know how it is, I have gotten into flame wars myself before.

If some of you guys want to battle it out, feel free to go to www.tealnet.com and register, then log in, and the "flame board" will show up in the message board listings only after you log in. It is a great place to tear each other up. Lets try and keep it off of here.

Thanks

 

Reno, why not just change pullies?

Like I said, I'm pretty sure 4.5 is the lowest it can go. I personally am not doing this until I get my 3.4 in a settled. Ed Wright doesn't think he's up to the custom chip I'll need though. Any other suggestions from anyone?

Learn how to burn your own eprom

MAF does present some difficulties when going over 255 gm/sec; but I think there may be a solution to that soon.

I am currently into the SD system and looking at ways of incorporating a 2 Bar MAP for that system.

Of course, you can always look at using the SyTy 749 ecm.

 

Was that a MAF engine? If it was, it might be just a swap in then...

Thanks for the lead!
