Adding Boost is addictive and a rabbit hole, however you will need an engine and brakes that are up to the extra HP. Make sure all is in order before modding your car.
There are a few threads here with tons of great info, either turbo or SC will require assembly & tuning skills.
Whats the condition of your shark and how much HP are you looking to add?
It this a Euro S or a US S car? If you have the 300hp Euro S high compression motor boost is kinda out of the question as more pressure has been noted to be a problem for the pistons.
My 79 4.5L had a supercharger on it, but I overheated it - not the supercharger's fault, but mine when I failed to see a coolant leak and had an inoperable fan.
Now has a 4.7L from an 83 in it and same supercharger. Setup makes 350 HP & 350 Lb.ft. of torque and runs the original 79 K-Jet fueling with AFRs exactly where they should be.
It's an awesome setup. I've driven the car with the supercharger removed and it's not the same car.
Custom cold air intake through the fender, dual-chamber AOS (heads into one and crankcase to the other), intercooler using washer fluid and pump as the cooling medium, Powerdyne supercharger with ceramic bearings, vented case, & vortex impeller.
I also have a 310 HP high compression 84 Euro S that I use as my DD and wouldn't consider supercharging that one because of the compression ratio and it drives great as it is.

Hi Dave,
Thanks for the reply. Sorry for the delay in my response. It seems that the messages went to junk folder. Condition is decent and as much as possible within a reasonable price and technical position. Any thoughts on a kit?

Hi thank for the reply. Sorry it has taken a while to reply the messages went to junk and I haven’t seen them until just now.
I can tell you that it is a 1982 4.7 auto Euro. I don’t know the hp amount on the car. Is there a way you know that I’d be able to confirm this?

Is your car a US model with L-Jet fuel injection or a Euro with CIS?
What kind of power are you hoping to make?
What is your budget?
EDIT - neverminded on #1, didn't see your next post until after.
Boosting a CIS car is tricky, it has been done, I have experience doing a couple of them and I'll never do it again. If you are serious about such an upgrade, figure into your budget switching to a tunable electronic fuel injection system first.

Interesting, thanks for the info. Do you have a link/product number to the supercharger kit you are running?

The Head Gaskets will be the first to go unless they are new or recently (last several years) done.
10 to 12k is a average cost by the time you add up all the extras that go along w/doing it
Have you read any of the Boost threads on here?
like the Twin Screw thread?
I did one on adding N2O, that's works too (although it has its downsides, keeping the tank pressure consistent is one) for your engine you could get away spraying another 50 to 75 HP, main thing is managing Knock (removing timing) if it's under boost or spraying.
As Eric stated the electronic Fuel Injection is a major consideration, although a vacuum controlled Fuel pressure booster can be added, IMO pulling Timing under boost extremely important.
Tuning will require monitoring & logging your AFR so you don't run lean under boost. Knock sensor(s) can be installed along w/ a Vampire unit to control it
Most of your questions have already been answered, in various boost threads.
10-12k will get you most of the way to a motor you -can- boost.
What's that supposed to mean?

No I wouldn't duplicate this system on a CIS Euro without first upgrading the fuel / ignition system.
There are Euros and Euro S cars. Regular Euros have the 4.5L engines, but those with the 4.7L are the hi-compression S versions and shouldn't be boosted.

Jean-Louis race car is an 84 4.7 liter Euro "S" with high compression, we measured it.
His car is run hard at Road America for 30-40 minute track sessions and PCA / Nasa races. He's one hell of a driver, so is his wife who shares the car on track weekends where it's often entered in multiple classes.
