Power Mods and tuning cars

So we've been busy updating our site and have the following new articles this month.

Power mods recommended for your car.

These are the mods that are usually performed by our members, decide how far you wish to go in your tuning project before you get going.

Getting the right mods for your planned usage of the car is essential. Stage 3 (competition) mods just don't work well on the road difficult in stop start traffic.

Stage 1 mods: Suspension upgrade (drop 30-40mm),Alloy wheels,Panel air filter,Lighter flywheel,Sports exhaust,Remap.
Stage 2 mods: Power clutch,Fuel injector & fuel pump upgrades,Fast road cam & vernier pulleys,Ported and polished head,.
Stage 3 mods: Internal engine upgrades (pistons/head/valves),Engine balancing,Competition cam,Adding or upgrading forced induction (turbo/supercharger),Sports gearbox.

Your goal when tuning the engine should be a wide torque curve. You don't want all the power to be at the top end of the rev range unless you are creating a competition car.

One of the best mechanical modifications you can do to your NASP engine is to fit a fast road cam .

 The intake and exhaust durations play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car impossible to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a performance chip to fully release the power gain.
You will need to ensure that the engine is not starved of fuel so will need to uprate the fuelling. Frequently power losses, flat spots and erratic idling after modifications are done can usually be traced to fuel delivery or timing issues.Uprated injectors will enable you to supply sufficient fuel to the engine. If you've uprated your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

New articles and models we've covered this month...

You'll also note that the forum has been given a facelift and looks fresher than ever. We boast more and more members now.
