Supercharging my Classic Mini

Over double the original out put just simply wasn't enough, so it's time to bolt a whopping Eaton supercharger and Weber carb, although in theory everything sounds simple, lost of little bits will take time.

The Supercharger kit is supplied by Stuart Gurr, of Vmax-Scart, the same person who's been making kits for over a decade and notably supplied the supercharger kit for the Mighty Car Mods car.

This kit, is slightly different, it utilises a weber 40, as opposed to the SU carb that Mini's originally had.

Now my car made on Peter Baldwin's Dyno (Notoriously inaccurate), 102bhp. To give you a scale, my boss's 1380cc engine with twin HS4s, made 114bhp on the same dyno, and a colleagues 1380cc engine with Twins and a standard cylinder head made 94bhp.

I will say, 87cc down on those two means this thing is much more a rev happy engine than a larger bore. Peak power was at 5800rpm, Stuart estimates 130bhp, but we will see what his dyno says later on!


For those of you who haven't already seen my car, here's a winter wash post a I did a few weeks back; http://www.detailingworld.co.uk/foru...d.php?t=385863.

Read that? Good, we'll continue.

Right, the strip down, to fit the supercharger, obviously you need to drive it with a belt, problem being is, the breather on the timing cover rather gets in the way of that, stuart supplies a snazzy plug, but I had access to an early non breather timing cover to get past that.

Either way, the timing cover needs to come off, so first things first. Rad out.

Sounds easy, but with the cowling, and not wanting to scratch my paint, I took my time, of course. All the coolant went everywhere. Expect the drain pan. Standard.


The rad is held in with two fixings at the top, and one through the cowling at the bottom, if you're good you can get the rad and cowling out in one piece. I am that good, but once it was out, undid the cowling as it needs re-painting.

Once the rad was out, I took the opportunity to remove the alternator, another fine art, to not scratch the paint! You could do it without removing the alternator, but it gives better access to the front bolts of the timing cover.

Next up in the remove it list, is the inlet manifold and carb assembly. Another, easy job if you've done this before, 1/4" ratchet on a short extension, with a 1/2" socket, I still need to whip the exhaust manifold off to change the gasket but, no hurry.

And today's final job was to remove the starter, 9/16 spanner for the top bolt and a socket on an extension for the bottom, which reveals my lovely lightened flywheel.

As you can see, the dirt on the subframe cleans of lovely, so next week's job is clean the engine bay, and then get the engine mount of and change the timing cover, I've got the well seal at the ready!

Amongst other jobs, I want to find a new plan for these headlamp connectors as they're ****.

And I want to re-do my dash cards, thanks for reading.

Cheers bud. I did watch it, they went all out running it on ethanol and injection. This is just a good old fashioned 40DCOE. :-)

Supercharger arrives on Wednesday, I'm working Saturday so Sunday I can crack on, want to get the crank pulley off. Sounds easy, but I sense it's not going to come off happy. Never know, it may just pop off! (Probably not!)

WellSeal is at the ready for the timing cover and a genuine Rover Klinger gasket, its that rubberised gasket material. For those who haven't used or don't know what well seal is, its an old school gasket jointing material. It's the sort of thing your grandad would have in his shed. The warning label on the back states 'Known to cause cancer', bugger it. At least the timing cover won't leak!

That's a lovely wee classic mini. I'd love to get a run in it after the charger is fitted. That'll be wicked.

Wow this looks good, can't wait to see how you get on. Miss my Mini, wish I'd never sold it, so much fun!

What 'box are you running to cope with the extra poke?

Love the wheels btw absolutely best wheels for a Mini.
