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 turbo or supercharger.
If the mixture is too rich a catalyst would be destroyed as unburned fuel enters the catalyst and burns inside it melting the catalytic structure so there is a delicate balance to maintain. … Read More...
Big valve kits – larger intake valves.
The heads primary job is the mixing of fuel and air and delivering this to the combustion chamber.
Any turbulence or drag can restrict the air flow into the engine starving you of power. So this TorqueCars article will focus on the intake valves and how they can be improved.
The aim of head tuning is both to maximise the amount of air and fuel that gets into the engine, and to improve the mixture. Read More...
Building a 10 second car
We look at what it takes to build a 10 second car and examine the power and weight requirements to reach the sub 11 second goal on the drag strip.
Follow our tips and you can make a 10 second car quite cheaply and within your budget with some power mods and serious weight reduction. Read More...
High performance valve springs
The valves are like the doorways into the engine and control the flow of the intake air and fuel and then after combustion they control the exit of the exhaust gases.
As you can guess the valve springs work incredibly hard, and as you increase the power of your engine the valve choice is vital.
TorqueCars will now take a look at the many considerations taken into account when selecting valve springs. Read More...
