I have mounted a G-ladder supercharger up to my slightly modified 2.8L(pully, K&N cone, chip, No AC or CAT, 12" glass pack, MSD coil). I started it up with the hose blowing in the air(not installed to the intake...test run). That sucker blew nicely and seems like it will add some nice boost though (too much boost?)I have never done this before and don't know what to compare it to. I need to run an oil line to the charger and back into the motor. That's the only thing holding me back. As far as PHYSICS go..... screw it! I want to install it and see if it makes me faster or blows gaskets. I'm just gonna go for it and see what happens (in a cautious manner). so where are the oil lines on my motor to send to the charger and to dump oil back into the motor????? Any ideas? I'm pretty excited about this and am getting a little ticked at this 1 delima. Give me some input! Thanks -FROG-

Put a T-fitting on the oil pressure sending unit and run it to the supercharger. Then just need a tube from the charger back to the pain. Drill a hole, weld in a fittin, and ur set.
NOTE: I've never done this myself, but a quick brainstorm seems it should be suitable.

I've seen adapters that allow you to mount your oil filter remotely. Basically there's a cylindrical metal block that replaces your oil filter and it has a supply line and a return line that run out to the new oil filter location. You could install one of those and put in a t-tap on each line, oil supply and oil return. It's a bolt-on solution with no drilling whatsoever so it can be easily undone if your experiment doesn't pan out (sorry for the pun).

The G60 supercharger is build for a 1.8L engine, with that displacement and in good condition witht the original pulley it will produce 0.6-0.8 bar / 8.7-11.6psi max.
When you put it on a 2.8L engine the pressure will drop, I dunno the calculation for that.
One thing: Running the G-charger without an oilline is _not_ good.. the charger is a fragile piece of equipment that needs a $1500 refurbishment every 60-75K miles.
If you it's in good state you could buy a smaller pulley to get more psi ppl overhere are swapping the g-charger for a roots-type charger to get more psi and reliability.
I've had a G60 Corrado a few years ago... nice piece of car
No pics... So I was thinking I would possibly not get the boost I want as well... due to engine size, but I don't see how since that sucker was blowing incredibly strong! My belt may be turning faster than a corrado belt causing the charger to move faster in perportion to the motor??? Is this a possibility? I am not looking for mega boost or anything, just a few extra horses for a little more fun. Ths guy is selling the charger to me for $400 bucks so I figure, that's not much to lose on a potiential small power gain. I will experiment a little more I gues. I only ran the charger for a sec and it had some oil in the charger. It should be o.k.
Hey Morninlight..... My buddy that owned the Corrado before it broke was bragging to me that he had the car up to 208 MPH!!!!!!! and it was super fast in the 1/4. Tell me your thoughts on this. Oh yea...it was STOCK!

oh.. I forgot that the cranckpulley of the Fiero could be bigger or smaller than the corrado's.. If the drivepulley is bigger the charger will turn faster. If your going experiment I suggest you find out what the pulleysizes are and calculate the max rpm of the charger.
The corrado redlines at 6500rpm, the v6 redlines at 6K so you have a little headroom but not much of the pulley sizews are a lot different.
I've had a Vw Golf Mark II 1.9 16v and that car uses the same gearbox as the Corrado, I could redline that engine in the 5th gear speed-o-meter showed 245kph@7200rpm so 208mph with a stock g60 is nonsense.. 208Kph is a better figure, the max speed according to VW is 230Kph~144Mph.
Nope... he was all stock told me he ran the car up to 208 and let out and went out for the rest of the night running the car at 205 MPH a few times... (Must be a nuclear powered 1.8L SC Corrado?) He also has a STOCK 1992 cobra motor in his stang running 11:70's, lol, STOCK (NO POWER ADDER)!!! oh yea, he did this on street tires too. He "Dialed in" at a test & tune meet. You don't "Dial in" on a test & Tune run. Friggin nonesence. I want to say he told me his STOCK Corrado ran 12's at the track too. Would you happen to have a shovel by chance? It's getting deep...

Either way, if it moves enough air for 10 psi boost (25 psi absolute) on a 1.8 litre, then it might only make a couple of psi of boost on a 2.8 litre at the same % overdrive
Math: 10 psi boost + 15 psi atmospheric = 25 psi absolute 1.8/2.8 = 0.64 This is a rough guess of the ratio of airflow required by these two engines. This number should probably be fudged upward a little to make up for the 2.8's miserable volumetric efficiency.
25 * 0.64 = 16 psi absolute, or about 1 psi of boost. That's run at stock % overdrive, so if you spin it faster, you'll get more boost.

Hello all. My 90 Corrado will run 137mph all day long, regardless of outside temp. Very solid feeling at that speed. In the process of engine transplant - 1.8 SC with way over 174k OUT, 20v turbo new turbo, custom intercooler, TT exhuast IN. I'll get a A1 Rabbit and install the 1.8 and charger. Should be fun.

In addition to the T junction your return line must be 2x the diamater as the feed line since it will be gravity returning the oil. I'll try to post some pics of a simple turbo install when I get home.

it's an interesting piece of equipment that must be cared for, when you treat it nice it will produce a pretty nice boost and a very distinctive sound!

That friggin thing looks retarded. Well funny is more ike it when you look at the video of it working. my roomate says that it takes alot of maintanence to keep it in tip top shape because the walls of the vains actually touch.

It's not retarded
I just needs refurbishment every 60-75K Miles
