Brakes - Rear brake bias adjustment

When altering the front brake set-up away from the standard installation, it invariably alters the amount of rear brake bias needed to re-balance the cars brake balance.

The problems start occurring when folk graft alternative brake set-ups onto the front of their Minis. Be this 7.5" discs onto a previously drum-braked model, or going from current standard disc set-ups to one of the 4-pot varieties. The question then is 'what bore size rear wheel-cylinders do I need?' Unfortunately this isn't straightforward. Actually, that's not strictly true - more on this later. The pressure developed in the lines determines brake effectiveness - aside from disc size, pad type, co-efficient of friction, etc. that is. Understanding this may assist in choosing which way you should go for your particular set-up.

The basic facts you need to remember when dealing with brake pressures is how they are affected by the components you use.

Engine - 998 Tuning, Bolt-ons

The 998cc engine is a very robust and tunable unit. It is also the most common engine found in standard Minis. See bottom for useful part numbers Terminology: MSC/MM - Mini Spares Centre/Mini Mania ID - Inside Diameter OD - Outside Diameter BBU - Big Bore Unit (refers to all 1275cc-based units) SBU - Small Bore Unit (refers to all sub-1275cc units, here the 998) BHP - Brake Horse Power LCB - Long Centre Branch Despite the lure of the much-advertised 1380cc alternatives, many simply want to get a little more from what they have at reasonable outlay. The single biggest restriction on any standard Mini is the 'breathing apparatus' - anything that is connected to the induction and exhaust systems. The standard exhaust being the biggest culprit - it is desperately restrictive in the name of noise suppression and cheapness of manufacture. Oddly enough it also increases fuel consumption when tested over a better designed, fre

Air filtration - K&N Air cleaner test.

In the forefront of Mini tuning, improving the over-all breathing capability of the very asthmatic A-series the air filter set-up is one that sees priority attention. All the widely available (and widely varying) stage one tuning kits include at the very least a replacement - and hopefully - high-flow air filter element to fit into the standard plastic case,

In the past few years (well, must be nearly 6 years by now!) since I got involved with writing for the specialist Mini Magazines I have been continually fighting with the problem of limited space. This has limited what I have been able to cover, both in subjects and in details. Up until recently (say the past year or so) I have been covering fairly broad topics in a fairly broad terms and detail. Basically trying to cover perhaps the most popular areas dabbled in by the Mini owning masses.

Engine - 998 tuning, bolt-ons (stage one)

The 998cc engine is a very robust and tunable unit. It is also the most common engine found in standard Minis. Despite the lure of the much-advertised 1380cc alternatives, many simply want to get a little more from what they have at reasonable outlay.

Terminology:
MSC/MM - Mini Spares Centre/Mini Mania
BBU - Big Bore Unit (refers to all 1275cc-based units)
SBU - Small Bore Unit (refers to all sub-1275cc units, here the 998)
BHP - Brake Horse Power
CR - Compression Ratio

To improve engine out-put, you need to increase the engine's 'breathing' ability. The stage one kit deals with all the easily bolted-on external parts, and represents the best increase for investment. From here on in the power increases will cost commensurately more money.

C-AJJ4008 ADJUSTABLE REAR ANTI-ROLL BAR FITTING INSTRUCTIONS

Jack rear of car up, and place securely on axle stands, positioned to allow maximum access to rear subframe/rear radius arms area. Remove rear exhaust hanger to exhaust clamp or un-hook rubber loop on late type cars. Using suitable saw, cut off centralising tab from bottom center of subframe rear cross member. Remove rear wheels and brake drums. Remove upper most and rear most brake back plate to radius arm nuts and bolts.

C-AJJ3313 PROGRESIVE REAR BUMP STOPS

This kit is intended for all hydrolastic minis, although it has been fitted on to dry suspension cars to give improved handling characteristics during motor sport events. Check all clearances of brake pipes and hoses and relocate if necessary. On dry suspension radius arms there is no hole for the bump stop bracket.

The come down after the Spa weekend was abrupt and for a week I felt little enthusiasm to even determine what had to be done, let alone start doing it! Fortunately my mood lightened, and with a week to go before the Silverstone Championship round I got down to it. Well, to be honest I took the car down to Altered Images on the Sunday afternoon, and Peter Vickers cast his diagnostic eye over the car. The front...

Once again I found myself swamped with work causing the now familiar last minute rush to check the race car over before departing to Donnington. This race weekend was going to be a very different affair than what has become the norm. Karin was having to work the weekend, my 'opposition' in my class and in another Clubby - Steve (Young) - has resigned himself to doing the last race of the year at Oulton park due to work pressures, and stats man and hospitality provider Keith (Manning – now Otto v

Mini Production dates

We have tried to get together as complete list as possible to show all the models made from 1985 onwards, hopefully this will help identify those cars that have been modified over the years. If you have any information that you know is correct or anything that you think is not right please let us know.

Historical Article - March 1992 - Wild Thing!

In 1988, a humble 1973 Mini 1000 was minding its own business somewhere in London, when along came a young Mini freak called Jason King, who wanted to change it for ever, and make it famous.

Jason persuaded the owner to take £450 for the car, and then proceeded to throw £12,000 worth of presents at it for the next 3 years. Every minute of Jason’s spare time was spent working on his new car and every minute of his working time was spent looking for spares.

Having built one Cooper ‘S’ for Timo Makinen to use in Historic Rallying, in which he won two International Rallies, I decided to build another one with more power and less weight than the previous one.

One lesson I learnt the hard way building the first car, was that a reliable source of new parts with in-built quality, especially where obsolete parts were being remanufactured, was essential. Mini Spares of London...

Historical Article - Nov 1992 - Good Vibrations

This year saw the re-introduction of the damper ring originally fitted to the Cooper ‘S’ engines and used extensively by a multitude of racers – until its demise instigated by the cessation of production by BL some 10 or so years ago.  Very unfortunate as this was broadly recognised as being THE crank damper to use on any performance of rally/race engine to deal with odd-ball harmonics produced by the 3 main bearing ‘A’ series engine.  Midget and Sprite racers mourned the loss more than Mini owners, as the current “thick” damper causes clearance problems – the damper hits the cross member under hard braking/severe engine braking.

Historical Article - May 1993 - Cable Network

Myk Cable might well have been accused of insider trading when the new 1994 Mini Miglia regs were accepted recently. Not only was he making the best of his position within the ranks of Mini racing by proposing them, he was also calling on fully 2 years worth of advanced testing of his new 1300cc engine spec which, even as we speak, is quietly blowing away Porsches and Lotus Elans for the second year running in the Spanish Historic Touring Car Championships.
