Fuel Pump Diagnostics using an Oscilloscope

Whilst trying to track down a fuel pressure issue on my 1.8K Series VVC, I came across some interesting techniques you can use to diagnose the health of a fuel injection pump in situ with an oscilloscope.

Gearbox oil filler / dipstick modification

This a DIY version of the Quaife Type 9 top cover that I first saw on Guy Lowe's gearbox.  It makes it much easier to check and top up the gearbox oil level.

Detailed information on K-series EU2 Engine Loom

A little while ago I redrafted the Caterham K Series EU3 Wiring Diagram. Recently I have been involved with helping a number of people with EU2 engine wiring issues and have discovered several problems with the published K Series EU2 Wiring Diagram, some of which were common to the work I did on the EU3 loom.

If you are considering using a Head And Neck Support head restraint when racing next year, there are a few things to watch out for. Below is some help from Andrew Smith, and a press release from Caterham Cars.

Safety Notice - R-clips

From SimonLambert? at Caterham Cars on 24th December 2002:

Hardware

A broad summary of all the available chassis/body types and various options that could be selected.

Coventry Climax Engine

Climax, an engine to be proud of

Electrics

GENERAL PROBLEMS

The answer to most electrical problems is to start by checking the earths in the car. The battery is usually connected to the engine by an earthing strap and the engine is separately connected to the car chassis by a further strap.

Cosworth Engines

In the begining the world was created and God saw that it was good. Then he invented motorsports and it was OK.

Reducing weight on a Seven

What is the significance of reducing rotating mass versus stationary mass, when lightening your Se7en?

 

Newton's Second Law of Motion states: "Acceleration is proportional to force and inversely proportional to mass."

 

Aluminium Chassis

The subject of Aluminium and its Alloys is quite complex and a correctly designed chassis with the correct alloy selection and proven welds may well be feasible but I am convinced that this concept would be beyond the scope of the average amateur in a "shed " environment.

Powerflex Bushes

Bushes are an interesting subject.

In the first place all bushes must introduce compliance into the suspension and this is likely to introduce certain non-linearities which could cause problems or could be used to remove design w
