Hey skssgn,

I'm pretty sure its a standard SU carb with a boost pressurised fuel bowl.
The system also runs a MALPASSI rising rate fuel regulator to increase the fuel pressure at a 1:1 ratio with the boost.
Say the base fuel pressure is normally say 4psi at zero boost.
Then at 10psi boost the regulator would allow 14psi fuel pressure (limited by the fuel pump of course).
The regulator stops the boost pressure pushing the fuel backwards through the jet.

Another note i should make is that the caby must be sealed as it becomes pressurised in the blow through setup.
This means any atmosperic vent must be connected to boost pressure and throtle shafts etc.
must be sealed when running heigher boost to stop the fuel/air mix leaking out.

SU's would be pretty easy as they only have one gasket on the fuel bowl and it would be
easy to use a bit of gasket goo to help seal it.
However is you use say a dellorto you have to make sure the fuel bowl gasket is up to the job. (IMO its to complex to use gasket goo on)
The turbo dellorto's fitted to the turbo lotus had a rubber fuel bowl gasket instead of a paper one.

Hope this helps please correct me if im wrong Pete,
Isaac

Pretty close. . . :)

Carb is just an ordinary old 1&1/2 HS SU, with plenum pressure directed into the fuel bowl. . .
Fuel bowl isn't the issue as far as fuel leaks go - it's mainly from around the throttle shaft and down past the jet. Fuel bowl gasket with no gasket goo has no problem holding positive pressure. Rather than shell out big bucks for a turbo HIF, I've gone the cheap and nasty route and Araldited the jet in ( :shock: ) once I'd set the idle muxture correctly. . .and I sealed the throttle shaft up with a bit of careful dremel work and a couple of o-rings. . .works fine and carb mods cost me a grand total of not very much.
Oh, and you do also need a restrictor in the carb mouth to reinstate the venturi effect that normally draws fuel out of the jet. . .I still don't really understand why the normal bridge in the carb doesn't do this with the S/C fitted but the evidence doesn't lie - without a restrictor, the motor cuts out and does all sorts of horrible things on light throttle cruise, whereas with the restrictor, all is good. . .

Another option with the Weber/Dellorto is to 'box' the entire carb and pressurise the whole thing. . .

Hey Pete?

Do you run a fuel/air ratio guage just curious?
I'm gonna mount one on my setup dont wanna run the thing lean and blow the motor :(
I'm gonna start working on my setup pretty soon (I hate getting paid monthly).


Also does anyone know of a good place to get an AISIN AMR500 Supercharger preferably in Brisbane?

Cheers,
Isaac

Nup, no AFR gauge. . .I figure that if I'm getting 16mpg there's plenty of fuel going in there to keep things cool. . .plus the fact theat the motor doesn't run even remotely hot and there's no detonation happening.
Monitoring AFR's would probably be a good idea if you're going for higher boost levels, though. . .that and keeping an eye on post-intercooler air temps.

I just found a brand new AMR500 on ebay but they want over a grand for it thats a little more than
i wanna spend i would rather put that kind of money towards the Starlet conversion i'm gonna do later on down the track 8)

Just thought i would let everyone know someone on here might be interested in a brand new supercharger.

I just want a good 2nd hand one wanna try and supercharge my mini for about $600ish if it costs
much more than that i wont bother i'll just wait until i can afford my toyota donk. ;)

Yeah i saw that but it looks a bit to big i think. I dont think it will fit mounted above the alternator.
Looks bigger than an SC12 to me any getting parts for it would be a nightmare.

got mail today here is the reply re superchager kit.

Hi . 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 of our Mini kit is $5375.00 AUD plus GST.

that plus a rebuild, and a couple of other mods and its the same amount you would spend on a conversion

Easy to see how good a deal 92's supercharger kit is , from memory about a grand plus the cost of the sc12 , lot better than that one . Admittedly you're using a second hand supercharger rather than a new one as per the other kit but the saving in installation costs will go along way towards the engine mods ....

Thanks for the info shorty,

But for that price i would be dumping a toyota starlet motor in stuff the supercharged a series.
For 6 grand i would rather a turbo 4efte :)

I wanna supercharge my mini for about $600ish anymore and i'm gonna save for the toyota donk instead 8)

i know it's way to dear i know it's a new supercharger but i expected it to be around 2- 2500. which would be ok.you could supercharge a big block chev for less then what they want to do a mini.

i'm looking in to it at the moment and think that using a amr300 with intercooler and a custom throttle body setup with efi i could build it for a round $1000ish but thats just an idea of happy hubby at them moment. he has tons on the go so it will be a while.

don't want to take over this thread and if mods want they can move this post. but hubbys idea is to run a custom injection manifold with 4 injectors and want to know if people think this will work as he has read it won't on n/a as no garentee fuel will go in right hole. hi plans the manifold with injectors point at ports and want to know people otpion iuf they think that the use of the super will help the fuel go where needed.
