Fuel and fuel additives octane and pressure boost valves.
fuel-full

Choice of fuel becomes more critical in a high compression or turbo engine. "One of my Pet(rol) hates!" Fuel: this is regulated by a pressurise valve at the engine end – generally more fuel means more power but you also need more air as well – certainly an induction kit on larger engines and preferably a […]

Low ratio sport gearbox setup and selection.
race-gearbox

Gearbox – Lower ratios give better acceleration times and lower fuel economy. Six or seven speed boxes are better matched to modern engines.

Most street applications are closer 1st and 2nd gear ratios for that off the line 0-60 boost or for the fast exec a lower 2nd and 3rd ratio give improved overtaking flexibility and 30 – 70 mph acceleration with a high 4th and 5th gear to give motorway fuel economy.

Flywheel lightening & performance gains from lighter flywheels
flywheels

Lightening the flywheel – the flywheel works in a similar way to the wheel in the toy cars you used to rev up and release and let it zoom off. The heavy wheel located between the engine and the gearbox builds up rotational force with speed and momentum.

Effectively storing the energy and helping the car resist changes in engine speed – good for cruising at a steady speed but bad when you need a fast engine response.

Clutch tuning: performance clutch modifications and triple plate clutches setup
clutch

The clutch takes the engine power, and puts this down through the drive shaft, to the driven wheels on the road but allows you to disengage the engine whilst performing a gear change.

Contact like this requires a lot of grip and a fast response. The more power you have the harder it is for the clutch to operate.

How to lower the engines compression ratio
con-rods

Reducing the compression ratio is required if you want to run a high boost supercharged engine. High compression NASP engines are quite efficient but when adding forced induction you want to lower the compression ratio.

The compression ratio has a dramatic effect on an engines performance and the problem of knock, (where the air fuel mix prematurely ignites) is controlled to a large degree by the compression ratio.
