Choosing The Right Timing Set For Your Engine
Why is a camshaft like the heater in your house?
Created: February 25, 2014
Camshaft selection can be as complicated as you like, but for the ultimate performance, even if that means best gas mileage requires that you consider the entire envelope that the camshaft will work within. Non-technical issues such as intended application (street, race, milage or??), budget, expected RPM range, etc must be considered along with technical things like compression ratio, Cylinder head and valve sizes, exhaust system, carburetion, etc.
Who is Kent Camshafts
Created: January 27, 2006
Established in the late 1970’s, Kent Performance Cams has grown from a fledgling idea nurtured by two engineers - Bob Munt and Bob Fry - into a world renowned specialist camshaft manufacturing team, a camshaft manufacturing house that was capable of producing competition engine components within strict quality control criteria whilst still remaining cost effective, a policy we still pursue to this day.Bob Fry - who took full control of the company in 1989 - has since taken a back seat in the running of the company leaving the existing management team - Tony Woodward, Andy Burns, Malcolm Hawkins and Graham Watts - as the primary Directors responsible for further growth of the company. Other key employees include Sales Manager Del Johnson, whose automotive experience spans thirty years.
Kent Camshaft Timing
Created: January 27, 2006
Kent Camshaft Timing methods. For many years the most commonly used method has involved establishing top dead center (TDC) as a datum (zero degrees) and positioning your camshaft with its inlet valve at maximum lift at a given position relative to this datum.
Duplex timing chain kit, C-AJJ3323
Created: January 30, 2000
The front plate will have to be countersunk as shown ‘X’ to take the screws CMZ407MS, which replace the existing hexagon-headed screws, which would foul on the timing chain. Check for clearance on chain all round and align gears as per Workshop Manual. When using ‘A’ plus timing covers there is a small round pressing at the bottom which needs making flat to allow timing chain clearance.

Adjustable belt drive timing kit, C-AJJ3328
Created: January 30, 2000
The ubiquitous toothed belt cam drive system, originally developed for use on high performance race engines, is now generally accepted as the norm on all state of the art, modern engines. The application of this drive system gives very accurate ignition tming and quiet running, advantages that do not diminsh with time.

This disk has a solid center with no springs or any other method of absorbing shock, thus it should not be slipped any more than absolutely necessary to get the car rolling (this is the reason you see film of race cars being pushed to get started)!!
Oil Coolers
Created: February 03, 2011
In the past, fitting an oil cooler was mandatory once an engine had been even slightly uprated. The main cause for this was the quality of Motor Oils available at that time. If the oil temperatures exceeded a specific point, then engine failure was almost guaranteed.

Modified to give maximum performance gain for cost. Combustion chambers, inlet and exhaust ports extensively re-worked. Stone-ground finish in ports promotes ultimate fuel atomisation. Three-angle valve seats in head. Cooper S size valves with current maximum flow profiles and Tuftrided for durability/longevity when used with unleaded fuel (hence 'black' finish).
Rocker Gear
Created: January 30, 2000
The new generation of short period, high lift cams have been developed to give the best results in large bore engines when used in conjunction with 1.5 ratio, hi-lift rockers. For the small bore range, the stock 1.3 ratio is optimum. In certain instances ratios of 1.7 to 1 are of benefit - but is really only applicable to fully developed race engines.
Cylinder Heads
Created: January 30, 2000
Everybody has their own opinion on this subject. The most experienced people will tell you that the best way to maintain your engine performance is to accept the fact that valve jobs need to be done 2 or 3 times more often than rings and bearings! And this data base was concluded when leaded gas was the norm! Now that unleaded is all you can get, valve jobs are needed even more often! The purpose of a valve job is two fold; first the valve seats. The impurities in the air and gas often get trapped between the valve and the seat in the head; under worst conditions stopping the valve from closing, but more commonly being smashed enough to allow just a little seepage of hot gases.
Competition Cylinder Heads
Created: January 30, 2000
A selected range of modified cylinder heads are available to suit a wide variety of applications. All port and chamber modifications are carried out by experts to current state of the art specifications. Therefore, actual specifications may alter slightly as gas flow and port velocity efficiency improvements are developed. Where large bore heads are used on small bore engines (i.e. 12G940 casting on 948/1098cc block), it is necessary to check full lift of exhaust valve, and pocket the block as necessary.
Competition head stud and nut kit
Created: January 30, 2000
This kit has been produced by Mini Spares to reduce head gasket problems on performance orientated engines, especially those utilising large over bore sizes. Standard type head studs and nuts are mass produced which unfortunately compromises the specification of the end product. Worst affected are the threaded portions which create problems during torque-down; thread deformation, stud distortion and possible stretch, off-square seating of the nut to head and so on.
High lift rocker assembly, C-AHT436
Created: January 30, 2000
Ensure that posts, spacers and rockers are evenly distributed along the length of the shaft to allow smooth pivoting. On no account must the valve springs be allowed to become coil-bound as this will place undue stress on the rocker and could lead to failure.
Offset rocker bushes, C-AEG644
Created: January 29, 2000
Using these bushes it is possible to achieve an increase in valve lift of upto 0.030". They must be pressed into the rocker with the thick section pointing forwards, ie. toward the rocker pad. It is advisable to use bearing-fit compound (Loctite) to ensure the bush does not rotate in use, taking up ‘wear’ in old rockers. Once fitted, they need to be reamed out to 9/16", for best easy slide fit on the intended shaft.

To maximize power and economy potential from any engine, burning the compressed fuel/air mixture at precisely the right point throughout the engines entire rpm range is essential. This ‘point’ is generally somewhere before the piston reaches TDC on its power stroke described in degrees - i.e. 10 degrees BTDC.
Changing from Dynamo to Alternator
Created: September 01, 2000
Completing this change successfully, easily and neatly is pretty straight forward on a Mini. The alternator contains the regulator and cut out functions within it’s casing, so makes the regulator box used with a dynamo redundant. However, it is useful to retain the box itself and it’s connectors.

About a year ago I read about the reduction of zinc dialkyl dithiophosphate (ZDDP) in the oils supplied with API approval that could affect sliding and high pressure (EP) friction in our cars. The reduction of these chemicals in supplied oils was based on the fact that phosphates reduce the effectiveness and eventually damage catalytic converters and introduce minute amounts of pollutants into our atmosphere.

Last time we started building a small-bore engine for maximum power. But there is no point having a good engine and putting the wrong head on it. I'm going to use the 12G202 head, as these are the best to modify for our purposes. They are a bit smaller than the 12G295 or 12G206 heads, which gives you a bit more metal to play with when grinding. As far as a standard head goes, you can't go past the 12G295 or 12G206.

This strap is used to give support and strengthen the centre main bearing cap on small-bore engines (850/998/1098cc). It helps counter the problems caused at higher rpm where crankshaft flex (‘whip’) causes the standard cap to move (‘shuffle’) leading to bearing failure and possible breakage of the main bearing caps. In particular, where higher rpm than standard will be the norm – i.e. in excess of 6,000rpm. Especially where this is for extended periods.

If done properly, converting your Mini to EFI can have many benefits. The EFI Engine Control Unit (ECU) can control all aspects of the combustion of the air/fuel ratio under all conditions. For each and every load point throughout the rev range that the engine may experience, the EFI ECU can calculate the optimum timing and delivery of fuel as well as precisely when ignition will take place by supplying spark at exactly the right time in order to maximise power and torque.

The HIF-series carburetor differs from the HF-series primarily in: 1) The design and location of the float chamber, which has been incorporated in the body of the carburetor, and 2) The introduction of temperature-sensitive mixture control (a bi-metallic strip fitted to the jet adjusting screw mechanism) to compensate for varying fuel densities resulting from changes in fuel temperature.
Synchronization of Twin SU HS-type Carburetors
Created: January 29, 2000
Before proceeding to synchronize your carburetors and for best results, some preparation is in order. Your carburetors should be in peak condition with no play in the throttle shaft bushings. If these bushings are worn, synchronization is difficult or impossible to achieve since there will be a vacuum leak past the bushings. Additionally, the jet needles should be identical and correct for the application; adjusted to equal and correct seating in the piston and centered in their jet bores (if not centered, you will feel a bind when moving the piston up and down).

Dog engagement is typically limited to racing applications where fast, precise shifting is needed. Dog gear engagement works by having numerous large teeth or ‘dogs’ that mate into matching openings machined into the opposite surface of the drive gear.

When most folk talk about limited slip differentials for cars with a BMC rear end, the minds immediately turn to the "Salisbury". Indeed many think that word covers any LSD for a BMC. This of course is not so. The Salisbury diff was designed in the 50's at a time when race cars were not sophisticated, tires were usually crossply with limited grip due to port compounds, and tracks were more than a little bumpy. Agriculturally built cars needed diffs built along similar lines. High static loads were more than common to help compensate for shortfalls in chassis and tire design -
