FAQ - Frequently Asked Questions

Whats an Ideal engine spec for these kits?

998 plus 20 thou Power max type high quality pistons, 12g295 ported head with 33x29 valves (or 12g940 head used with the decompression plate- this gives the necessary valve clearance over the block) , balance rotating assembly, our billet supercharger cam, 2.9:1 final drive for 90 bhp/6000 rpm 90ftlbs /4000 rpm  

1293/1312cc Omega 18cc dish forged pistons (0.020 thou or 0.040) these are the heart of the engine so get the best ! Good modified cylinder head with 35.7x31mm race valves, our billet supercharger cam,  basic balanced rotating assembly and conrods, uprated clutch -turbo verto or grey cover pre verto road weight flywheel, taller final drive 2.7:1 in the gearbox, helical cut gears. this should give 145 bhp/6000 rpm /150 ftlbs -4000 rpm 

Can any  mini be supercharged ?

As long as its in good condition : has good oil pressure, does not use any oil, and  no crank case breathing, then yes ! You can supercharge your existing engine or build an engine to suit. Different kits are listed here for MPI/SPI or carb models, SPI's can be run on a carb supercharger kit with a distributor and using a fuel regulator (see parts) to keep the current fuel system if emission limit are less important. You will need an electric fuel pump and a larger alloy radiator to keep temps down with the extra power demands.

Why isn't the carburetor rubber mounted?

The carburetors are modified to run a solid mounting in this application.

What kind of superchargers do we use?

We use Eaton M65 and M45 superchargers, they are pre-owned, rebuilt and modified to suit application.

How long has VMAX been making Superchargers?

The First Eaton supercharger kit using the M45 from a BMW mini cooper S was made by me early 2004, previously I had been Turbocharging Minis, from 1989.

What engines do these work on?

The kits can be configured to work on anything from a standard 850 to a race tuned 1400. Wilder cams are calmed to become more track-able and mid-range torque increases make cars fast even if you are not using high revs.

Can I buy a kit without the supercharger?

Not at the moment , there will be  DIY kits available soon. 

Can I use my own carburetor?

If you send your carburetor to me I can modify it to work in this kit, but usually this works out a more expensive route as the carburetor supplied comes pre-jetted and correctly set up  for use with a supercharger.
