Performance Transmission modifications

Low ratio gearboxes,slip differentials and performance gearboxes

Getting the power from the engine to the wheels is the job of the transmission and this is an area where a lot of cars can lose power.

We look at the best Transmission mods from low ratio gearboxes, quick shift kits and slip differentials.

Converting a FWD to a RWD

We look at converting a front wheel drive car to rear wheel drive. Problems and shortcuts and suggestions for a FWD to RWD conversion project guide. For this reason, most high power cars and motorsport cars have a rear wheel drive setup. Even front engined street cars are converted with a mid mounted engine and rear wheel drive.

Cars are more fun to drive when the power is to the back wheels. It makes for lots of oversteer rather than the safer and more predictable understeer manufacturers build into FWD cars.

DMF vs solid flywheel conversions

We look at the benefits and disadvantages of solid flywheel conversions from a DMF and help you decide which is right for you.

It is our considered opinion that unless a car is used extensively for competition or off road you should stick with a DMF. The additional torque caused by tuning an engine or heavy competition use can quickly destroy a DMF. The solution would be to fit a stronger, higher performance DMF but the aftermarket industry seems geared up to offer solid ones as the upgrade option.

Flywheel lightening & performance gains from lighter 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

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.

Principles of porting an engine and big valve conversions

The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.

This allows for scope in the manufacturing process to allow for mismatched alignment.

Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
