After struggling to find much info on this topic, I’ve resorted to ask the question my self. (I’m not old enough to have a Mini yet but have been reading Vizards books a lot) Thanks in advance.

rather old skool and expensive. Put Shorrock into the search and you will find a few topics on them.

You are old enough to have a Mini

 

Maybe not old enough to drive one legally on the public road...

 

If you have somewhere to keep one you can have one...

 

I had several before I was 17 and today you can race Ministox from a young age [need to check regs]

 

Shorrocks blowers are pretty good at low boost

 

But have quite a few moving parts which wear and are difficult to have remade

Cheers for the answers guys. (Side note, my dad already has 3 Minis and their isn’t another garage to support a 4th!) Just another question, how much BHP could be made with the ‘charger?

The more common superchargers and readily available chargers are the Eaton m45 iirc.

Allard's book is good...bit old school now but even has the A series engine in and loads of advice

Almost 60 years ago, I was given a second hand Shorrock by Allard.

 

It fitted above the engine in a Morris Minor and I drove it from a second pulley on the waterpump.

 

Without any other modification, it gave me an average estimated  25% increase in power over most of the rev range.

 

Over the years it got swapped onto at least 20 different A series engines of various sizes and always made the car more fun, and more pleasant to drive.

 

The biggest power increase that was actually tested on a rolling road, was a peak of almost 40% on a 997 cooper

 

Shorrocks wear out, fact of life.  I rebuilt mine many times, incorporating some modifications to wearing parts, and it was a very sad day last year when I reluctantly had to accept the it was finally worn out.

 

An Eaton supercharger from a bini is more efficient and by it's design is far less prone to wear.  I have bought one, but it is still in it's box.  I'll get around to fitting it some time, but for the moment, I'm still pining for my old Shorrock.
