Supercharger Question.

[P.B.I.]

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.

the jackson racing bbk is about 8psi and you can gain a few more psi with an 5.7" od pulley, this will just about max out the blower. as there is no intercooler you will definately need wmi to coll down iats. the focus boys seem to think 200 whp is about the limit from this kit on the zetec.
the jrsc uses its own intake manifold to which the compressor sits on top.

see pics.







if you take a look on focaljet there are some zetec foci using centrifugal blowers and there is a wealth of information too.

do u think the SC was worth the cost? and how hard was it to install. also, this may sound dumb, but from what u were saying, what does wmi and iats stand for?

WMI=water/methanol injection (IIRC)
IATs=Intake air temp's

and yes FI on a zetec makes a HUGE difference.

Yes it was worth it EVEN with the ATX.

is it possible to do on a 95 car, cuz they are all OBD-1 computer hookups...

as said above its worth doing. it was pretty straight forward to install on my 2000 (blacktop) mondeo. i had to get a focus alternator because the mondeo one was a bit bigger and the bracket fouled the inlet manifold. i also had to change the idle control valve to a focus one as the electric plug on the mondeo one came out at 90 degrees and fouled the bypass valve on the sc. a focus one is straight.
i had to modify a bracket that fits beneath the inlet manifold and supports the whole thing.

i also fitted a focus central 65mm throttle body and needed to fit a focus throttle cable bracket.

then i had an after market chip fitted and a custom tune as the jackson racing reflash of the stock ecu wasnt any good to me in the uk.


a buddy of mine has a pre 98 mondeo (mk1) with the silvertop motor and has a jackson racing sc on his but it needed some more modding to fit. i believe he had a spacer fabbed to fit between the sc and the inlet manifold and an alteration to the alternator bracketry.

he to has an aftermarket chip and a custom tune.

I'd really love to see pics of your buddy's pre-98 setup. Maybe something that I haven't thought of. The biggest roadblock to putting a JRSC on a pre-98 is the idler pulley and alternator mounting.

WOW I'm getting forgetful. That's right, Percy did have a Pre-98. But I thing he was using a small honda alternator or something.
