Superchargers - Are they really a good investment?

Can i just ask something while your all around. I got the car cleaned yesterday and got talking to a chap that recons he knows a lot about our cars!!! He said you cant put a K and N filter on a monaro because the engine would suck it in. Is this true? He also said the filter i should be asking Monkfish to fit is a something VIPER filter. Is this also true?
Please help I'm blond and very dumb
I suspect the only thing sucked into his engine has been his brain Please help I'm blond and very dumb
Right then, just to basically sum up and get back on topic:
Superchargers are worth it then and having one will give me a real bang for my buck.
Just one observation, or question, I read somewhere that the 112 s/c's were originally designed for engines under 5 litres? Not that I'm going for that just thought it was curious that 112's are still being fitted to our 5.7's.

112 is slightly smaller in volume than the 122, if you dont want 500 - 600bhp then a 112 will be fine, the 122 will be able to pump more air per revolution and as such more power. If you can afford it go for the 122 though as once you have the bug you will want more. Oh and go intercooled as you will end up doing that anyhow!
Well it looks as though I'll be going the 122 route anyway. Been presented with two options at the moment. The first option (and probably most cost effective one at the moment) is the Magnuson kit.
Granted, it doesn't look as 'factory' as the Harrop, but the Maggie does come in a fair bit cheaper as the Harrop needs some work to accommodate the elctronic throttle assembly which bumps the cost up a bit more (I'd rather spend the difference on a Quick Rack).
As I say when I started the thread, not faulting either set-up they both have good reviews and no real bad points and at least no one has said one is better than the other! Just trying to justify (or make my self feel better) about quite a large financial outlay.
Thank for the sensible debate on this and the help that you've all been.

And to the 6L. VXRDAZ has a 112 on his vxr and has done a 13.2 quarter mile. Its on you tube. I was just watching it actually. I was also reading the thread with the red hot exhausts(i think it was the Magnacharger clip and was wondering, our exhausts don't get that hot do they. I suppose with the airflow or a moving car they wouldn't get a chance. Is that also the purpose of a inter-cooler or is that to cool the air going in or out of the supercharger(i hope you can make sense of that. I know what i mean i think)

So i'm guessing the next time i see you in Llandudno you'll be sounding a bit different. I also hope i dont pull up at a red light next to you:
:
Go for it mate. If i was you i would be so excited. You'll have to come down to a drag day to give it a go.
Bloody hell i'm excited for you

The 112 has a displacement of 1.8L and a red line at 12,000 rpm, so the maximum it can flow is the equivalent of about a 7.3L engine with 100% efficiency or about a 9L engine with a more realistic 80% efficiency. Assuming the same rev limit for the 122 that works out to about 8L and 10L respectively. That seems to be a useful increase over a 5.7L NA engine.Edited by GreenV8S on Sunday 5th October 20:49

Actually the LSx series runs very close to 100% VE (and in fact up to 103%) over quite a bit of the range. A benefit of good heads and intake tuning. Maybe the crusty old SBC only gets 80% but engines have moved on.So if it flows the same as a 7L engine, a 7L engine would be a better bet as it would not have any additional mechanical power loss. I understand this can be a 100bhp loss easy. Plus the load on the smaller engine would be a lot harder on it than the rwhp would suggest due to the additional load lost driving the SC. Talking the 112 here anyway.

Yep - intercooler just cools the air charge before combustion
Pendant mode on
Technically what is referred to as an intercooler is actually an aftercooler as it is located after the forced induction unit. Intercoolers are mounted between two forced induction units mounted in series (say twin turbo). You can have a beforecooler but the are more often used in static generators.
Pendant mode off

Intercooler, between compression stages.
As the boosted (compressed gas-mixture)leaving the blower is being cooled prior to compression in the cylinder, it is an intercooler.
Pedantic mode off.

When the incoming air get compressed rapidly (by a super or turbo charger) the temperature rises* (adiabatic IIRC) hot air is not what you want if you want to get more out of the engine. So, you will want to cool the charge of air going into the cyclinders - hence the intercooler.
Hope this helps

* think about what happens to a bicycle tyre pump when used - the end gets hot.

DevilYellowCV8,
Just to cloud your decision even more, Harrop have recently announced their new Eaton TVS package called the HTV2300. It’s the latest and greatest Eaton four lobe rotor that is much more efficient and pumps more air too; 2300cc/rev. It also has a new wider 8PK pulley and belt system with their own new tensioner. I’m sure Roger will be supplying it soon......

It's a while off from what I gather. I assume that the new Harrop will fit the LS1?Just to cloud your decision even more, Harrop have recently announced their new Eaton TVS package called the HTV2300.
