Supercharging a carburettor engine

[daveEST]

Hello!

I have a question about supercharging carburettor engine. I would like to try something funny this summer with my old, 1.2l engine car.
Now i have decided i will try to install centrifugal compressor (belt-driven supercharger). I hope I can buy used one for not too much money.
It shouldn't be too complicated to make the charger run with the belt on crankshaft.
But - ´where should the boost be directed to ?
a) to intake manifold ?
b) into the carburettor ?

Thnx!

Sounds like a question for 4Hammer.

From what I have read (no real experience) you need the carb to feed the blower, some carbs are finickey at the best of times, if you start pressurising them you are asking for trouble.
Most carb/blower setups you see have the carb feeding the blower eg -

Ok, thank You. This photo was very explaining. Now I go to look for tha blower. Damn, it's exciting :)

Hey stinky is that a grey motor?  If looks sweet, got any more photos or info on what the supercharger is?

That's the photo of the Rod Shop (www.rodshop.com.au) site for their jap blower kit for the Holden Red motor. I have seen one of these on a local LJ Torana and they look the goods, apparently the cooling system needs to be up to scratch or upgraded though.

Hi Guys.
He sounds as if it is a little 4 pot motor, @ 1.2l. I don't know much about them. Get a Holden motor Dave, the only way to go.

Mike Perth. Here is a shot of a Norman Supercharger on a Grey motor. The first one is an early cast iron one. It is in a beautiful EJ Premier. Goes very hard with a 5 speed Toyota box.

This is another Grey motor, with a later "Type 65" water cooled Alloy Norman. A nice little package.

Here is a shot of my "Type 70" water cooled Norman. It is on a dummy block. With all of these, the blower is after the carb. Best way, otherwise the carb gets pressurised.
Ask Tony C for his advise, he knows more than me.

Thank You all for so many answers.

Now I understand that are two possible choices:
1. Carburettor feeding the blower
OR
2. Blower pressurising the carburettor

Now I have to think whisch would be the easiest way to get the thing working. The 2nd version probably needs some funky carburettor which is not cheap.
So i think I will try carburettor => blower => intake

4hammer : There no chance i can buy engine You said(money!! :)) If the installation should be successful and the the blower will give only a very little affect to the engine, then i am happy already.

EDIT:
About small engines. 2 years ago we had a guest from Finland with fiat or something like that. That car had 1.1l engine , but it beated our nr1 1/4 mile car, Camaro 7.4l .
There was a topic about extremely high turbo pressure of that little car, but I don't know exact numbers.

Try http://www.hi-flow.com/ for superchargers for little motors, they specialise in mini's and sprites/midgets.
