Supercharging a 172?

Just having a browse round on ebay and noticed you can pick up bmw mini superchargers for not as much as you'd think.....Just got me wondering if you could supercharge a 172 with one or infact if anyone had already done it? and what sort of power increase they gained?

Cheers

the eaton bmw chargers are a good choice for a 172.

ben P - what sort of money are you talking to do such a conversion do you think on top of the Supercharger itself? and what sort of power gains? I wouldnt be doing TB's though....

lol no not ktec

but it looks like you have to uprate all your internals, costly job

and the guy that said ITBs and a supercharger.... why??

its one or the other

i'd be doing it on the cheap, just wondering how much more i'd need other than the supercharger unit itself (in terms of plumming ect)

obviously you'd need a certain amount of customisation in terms of mounting it ect.

400 BHP is a waste on a Clio or any front wheel drive cars. For the cash it would cost you could have a decent car - Evo etc

400 Bhp can be put through the Front Wheels quite easily if you know how, My Bro-In-Law is almost running 400Bhp in his Fiat Coupe and he puts it down easily, Those who say they would rather have 220 Bhp instead of 400 Bhp are talking outta there arse, You would kick yourself if you got thrashed by a 400 Bhp car and you'd opted for just 220 Bhp

Just My Opinion

Supercharging my RSi is my main tuning aim, within the next year or 2, unless i chop it in for something else.

That is not actually true, in fact quite the opposite. You can supercharge an engine without any change of internals, then remove it when you want to sell.

Met a couple of guys at Spa that had civic type r engines running over 300bhp with bolt on superchargers and no internal changes at al.

With the Mini superchargers being designed for a smaller capacity engine (ok not by much but still) would they be adequate or would you need something meant for a bigger engine? Or does that not matter with a s charger? :)

Depends how far and how good the engine is the k20 engine is different than a Clio and can take 300hp on stock internals as its a better engine.

Idealy want somehting bigger as you don't want to overspin the charger.

Since my mate has a SLK 2.3 kompressor I thought and have a look at that but it seems they also made a 2.0 kompressor.

http://www.autoweek.nl/carbasedata.php?cache=no&vpos=&id=21115&cache=no

Sorry for the Dutch link. Anyway It's a 2.0L engine and uses a compressor. I haven't looked into howmuch boost the compressor delivers, I understand the stock clio engine can deal with a 0.5bar overboost (as some manufacturers are offering low boost turbo kits (o.5 bar)).

I am not a car mechanic, but the 11:1 compression ratio and the 9.5:1 from the merc seem a bit off. So there might have to be some pressure reducing.

Also the compressor seems to be mechanical, (I guess this means that it isn't belt driven) So then you are looking in modifying the engine heavily and might aswell change internals.

Boost on the compressor engines is very low due to the design of the chargers used.

Idealy you'd want to lower the CR of the engine but depends how cheap you want to go about it depends if you would.

You can make the superchargers work but idealy turbo would be the way I'd go given a choice.

Edde may I ask why you would choose turbo instead of compressor? Maybe you could say something about the pro's and con's of both?

And are there any real electric compressors/ turbo's for cars? (not those ebay things, but that really work) I have seen some hybrid, but that's it.
