I guess it’s time I started a thread on my mini. Mine for 20+ years. After being my wedding transport back in 2011 it came time for a bit of a weldathon....

What's a strapped crank?

The first dry build used a stock 998 cast manifold shaved down. This has now been replaced with a pair of custom maniflow manifolds - an LCB and a short HS2 manifold.  |

It has a 3 bearing crank, so when you back off at full noise it can whip. The strap reinforces the bottom of the block to stop is shuffling and breaking up. |

So today’s mission has been to retap the front plate on the motor to support the charger. This meant pulling the radiator fan, timing gears, engine mounts... Hopefully I’ll get it buttoned up with a new water pump once that arrives in day or two.  |

So the new water pump is in. Manifolds buttoned down, belts on. Was going well until I set fire to it.
Turns out I left the battery hot lead on. The new oil line fell onto the solenoid and glowed red just before the oil caught fire.
I grabbed it off and put it out with a handy tea towel.
I didn’t take any photos at this point. More will follow but once the fuel, boost gauge and oil lines are on, it’s bolt down the head and start refitting the cooling system.
There’s a new old stock dowty Autofan waiting, that should be worth 4bhp...

Guessing that might be a shorrocks supercharger - which I actually know nothing about apart from the name?! Looks like a period kit of some sort, what's the story behind it?

Hi, spot on it’s a 60’s shorrock and a kit for a mini. From what I can see they were made throughout the 60’s for a range of motors.
My kit was incomplete, I bought it of a guy who had it as a spare for his supercharger meth running speedway bike.
I’ve spent a couple of years finding this missing parts and working out how it actually fits in as shorrock did make a manifold (of unknown dimensions). In the end I got maniflow in Salisbury to make me a custom LCB exhaust and steel inlet so it all fits in! Just!
The charger it’s self is a fuel through, vane charger. Total loss lubrication and should hopefully get about 7psi of boost on a 998 motor

Looks like a very neat installation, certainly less intrusive than letting a box into the firewall for a 45 for example, but I'm guessing equally as 'musical'...

I'll be watching this with interest, ive read a bit about the shorrock superchargers but never had the chance to see one up close. Its a real period part!

Following with interest as I’m still gutted I missed a Shorrock a few years back. Got a tip off about a chap who had a load of Mini bits including a supercharger he was thinking of getting rid of. Like yours it was incomplete and possibly from an MGB or similar as it looked a bit big for a Mini. Sadly, after much procrastination he decided an incomplete 998 engine and a box of odds and sods was worth hundreds and the two bits I wanted ( the ‘charger and a S distributor) he’d hang on to ‘just in case!’ 😩
