When they are fitted to an n/a engie would you have to do similar stuff to fitting a turbo e.g. bigger injectors, low compression pistons e.t.c...
Do you just change the gearing to up the boost? Also, I guess they have maximum bhp ratings like turbos?
They need intercoolers and dump valves right?

There is a lexmaul kit for the XE Ed. Its WELL expensive, £3k IIRC. Only gains 50bhp, but should be very useable power low down the revs!
Im not sure to the answers to your questions tho

you dont have to run an intercooler to run a super charger but better performance if you do 
Look at the rotex site or Jacksons site

Lexmaul ones don't fit RHD cars... Was looking at the Enem kit and it's the same as the Lexmaul one only a grand cheaper, though it still doesn't fit a RHD car

Er, i'm talking about the car... All the kits available fit to the throttle body, so your drive belt and 'charger hit the brake master cylinder...

I remember seeing a kit for the Xe but it was really expensive. They sound feckin amazing imo--- I would happily drive supercharged cars for the rest of my life. The power is so useable.

Supercharger works on the same principal as a turbo charger in that it basically forces air into the engine.
More air + more fuel = More power!
The difference between a turbo charger and a supercharger is that a turbo is spun off exhaust gases wheras a supercharger is spun via a belt connected to the crank.
Main problem of a turbo charged engine is lag. As the engine is a lower compression than a naturally aspirated engine off boost they are very sluggish. Exhaust gases dont really get flowing until around 3000rpm - No exhaust gases means the turbo doesnt spin up and air isnt forced into your engine - Lag!
You dont get this with a supercharged enigine as the belt is always spinning so the supercharger is. Superchargers are nowhere near as effecient as a turbo tho as to start with the engine is under load to spin the supercharger.
Loads of advantages and disadvantages of each tho!

Lancia Delta (that the one?) had that in Group A/B Rally - now that was rapid  
But yea i had that idea this morning after someone i was talking to was thinking about fitting a blower to an XE, but take it a step further and fit a blower to a LET - although im guessing its not as easy as it sounds

Ed, there is a guy on migweb who did his own supercharger conversion on a 20XE
Im sure if you buy a LHD kit, you could fabricate a few bits and peices to make it RHD...
give me a few mins I will see if I can find a link...

also theres that supercharged mk3 astra in holland that uses a twin screw blower - i remember reading the site and he had a few problems to say the least
but it sounded nice

Yea, if I were to do it I think I would need to fit the charger where the PAS pump would normally be, not to the TB....

Skyline engine plumbed up with twin turbos feeding super:
Just means the supercharger intake is already compressed, then gets compressed more by the time it reaches cylinders and silly power happens

Yeah, the Group B Lancia Delta Integrale had twin turbos and twin Superchargers! Think it ran a lag free 500bhp didnt it?
Its called compound charging when you use both!

you don;t need to do the same things because they don;t produces as much thermal load. an oil cooler is advised as is mapping but you can basically stick on on a standard engine, add extra injector and a UNICHIP and run 6-7psi no problem.
you can intercool, fit low comp pistons etc if you run lots of boost. S/C also spool slowly so you get a smooth progression from no boost to full boost.

Was just chatting about this to someone, cheers for that picture ash as i was sure you can do both, and yes i heard of compound charging before as well.
Turbo you get the almighty boost in one go, supercharger is a gradual increase in boost through the range.

aye, ran 470 i believe and was rear engined (well behind the front seats) - but from reading it was suppose to be abit of a handful but if you ever see videos you will see the power this thing produced - plus the noise
ash - the idea of feeding the air from the turbo's to the chargers is pretty good, seems to be a better idea that running seperate intakes like the Delta did (from my understanding etc)
