I have a pre '98 AWD Ford Mondeo Estate which i'm in the process of modifying. I'm looking at modifying the engine and want to go for a supercharger however I don't like to go on the normal route. Bit of an awkward sod me!!
The T'box in the AWD I have been informed can take anywhere between 250-300bhp so I want to squeeze as much torque as i can out of the little 4pot. Ideally i'd like to get a stroker kit if such a thing is made or possible. Also I know I could buy a Jackson Racing kit but that's limited to at best 8psi and if i'm correct uses the stock Inlet Manifold. The stock manifold is a very limiting factor as can be seen when you add throttle bodies which, even on a naturally aspirated engine can unleash over 20bhp. I was looking at using a Centrifugal Supercharger such as one supplied by Vortech, throttle bodies + all the necessary electrical kit that goes with it and fitting an Intercooler, the likes of a Saab 9000 as with minimal mods it'll fit comfortably.
Tell me though, can anyone tell me what are the pro's + cons of using centrifugal blowers over roots and other types of blowers? With a centrifugal type I can run higher boost and get bigger torque but has anyone any idea what psi roughly i'd have to run to get up to 300bhp. She will obviously get headwork + cams, custom induction kit etc to up the power naturally first. I'm looking for as instant power as I can get to get the big Estate moving quick, especially with AWD?
All answers welcomed.
