Got a reply to an email i sent to HP High Performance Products in Victoria regarding the supercharger kit in question. I asked a few questions and this is the email i recieved back, very helpful people it seems.
Hi Rodney. Thank you for your enquiry.
Our supercharger kit is designed to be fitted to a basically stock engine.
Provided the engine is in good condition, and within manufacturers tolerances there is generally no extraordinary mods. required in the milder stages of tune.
Bearing in mind that some of these vehicles are now nearly 40 years old, and more than likely, have been rebuilt or modified from the standard specification, this must be taken into account when designing a successful supercharger system. Many rebuilt engines have a higher than original comp. ratio, and camshaft changes are often made at the time of rebuild.
However, many mod's which work with conventional tuning can also be successfully employed on supercharged applications.
Generally we find that the 96 octane (roughly similar to 91 US) fuel available here is the limiting factor in safe power production.
Therefore we need to ascertain the actual ratio of each individual vehicle to establish just how much boost could safely be used. We tailor each kit to suit chosen engine spec. and available fuel octane.
Excellent results have been possible with 8.0 and 8.5: 1 comp. ratios.
Prior to delivery we will require the following engine details:
Bore size (if altered from stock)
Stroke (if altered from stock)
Compression ratio, (or preferably cc of comb. chamber, cc of piston bowl, deck height)
Fuel (octane rating) available
Desired boost (or power) be realistic now !!!!!
Camshaft timing profile,
Fuel (octane rating) available
Power would start around 30% improvement over standard and could reach 100% given the correct set-up.
In our kit fuel requirements are taken of by the SU HIF 6 carby supplied (the metering needle fitted may require slight changes to suit each individual installation). The distributor advance curve should, ideally, be modified to suit the engine's new requirement, or we can supply a brand new Bosch distributor with a suitable curve.
Our comprehensive kit includes all components (incl. new SU carby and K&N filter) to convert a standard Mini to a supercharged Mini, including detailed fitting notes.
The list price (for current stock) of our Mini kit is $5375.00 AUD plus GST,
Anticipated price for next production batch $5920.00 AUD plus GST.
and freight to Brisbane would be around $50.00 AUD

http://www.hi-flow.com[email protected]hope this helps out a few people considering the kit, me on the other hand, its jus that lil bit too expensive for me, may have to go down the sc12 route but im still not 100% convinced about that supercharger....
. Extra heater and fuel hose length cost me about 50 bucks. It all adds up but still is much cheaper. According to '92' it should run about 6-7psi.
