I forgot to post up anyone with a 32/36 webber on a supercharger what jets do you have in it

Use the same jets for naturally aspirated and for draw-through, except for bigger power jet and larger acclerator pump nozzle. See Weber DGV Tuning.

The important thing -- make absolutely sure the mixture is correct before flogging the engine full throttle.

Pinging can be fuel mix as well. There's a few things you can do. A good start would be to pick up a narrow band oxygen sensor, probably get one or two from the wreckers for not much, they're pretty cheap new as well. Then head to Jaycar and pick up a exhaust oxygen display kit, was around $15- last time I looked. Weld a bung on your exhaust and you've got a cheap way to check the fuel mix. Or you can get a wideband with a guage for around $200-.

You can make a bung out of 3/4" (~16mm ID) water pipe. Cut to length, grind the casting flash off the inside, grind to fit the ex-pipe just after the flange and cut it with an M18 fine thread. Then weld it on.

While you're stuffing around with it setting up water injection is a good way to protect your engine (or leave it on to allow bigger boost). There's a few ways to achieve this, the simplest is a sealed bottle that uses boost pressure to push water into the blower inlet. You want to flow around 70% of fuel flow. Google will come up with plenty of different water injection methods.

1- make sure your fuel's right
2- if it's still pinging even with the timing wound back you'll need less boost, water injection or high octane fuel

Get all that right and it should be a hoot!

Been doing some reasearch how about su carby draw through some place i found in vic called high flow who make su just for superchargers for minis thou i email to see if they be good for a datto a15

That place in Vic one of the workers has a mighty boy with billet supercharger and su no injection and he fits them to minis bmw and sports cars as well and swears by the SU carb for simplicity but also H20 injection for higher comp setups. Some are experimenting with h20 and e85 mixes as well.

Go for an efficient supercharger like the twin screw which are 70% efficient as the roots usually produce too much heat. The twin screw are the standard SC used throughout the world by most manufacturers on higher comp engines than usually boosted applications.

Try a merc or bmw mini Twin screw SC easy to get from ebay, even one almost new one sold on Ozdat for $180 about a year ago. Adjustable ignition like megajolt or a modded distributor by some expert and good tuning is a must.

Venture into mini sites in the UK and see ugly little cast iron under 998cc mini engines making 78hp at the wheels thats better than most fully worked big bore A15 engines. Even some on utoob.

I thought that minis ran the eaton M45? Thats still a roots blower. it just has a helix on the rotors, which reduces pulsing.

They're probably talking about Hans Pedersen who did work in collaboration with link automotive (aka mini link) (both in thornton crescent mitcham) - in particular Brian Pope - who have made supercharger kits (the lysholm type) for early A series minis. I haven't had any contact with link for probably close to 12-15 years now (about the last time I had a road rego'd mini!) so no idea if the kits are still available but I would suspect so.
