Careful selection of your internal engine tuning modifications can lift your engine from a purring kitten into a roaring lion!
While it is tempting to throw in every modification you can, it’s worth noting that not all mods work well together. This is something we cover in our articles as we steer you to the right decision on mods for your car.
Remaps for diesel engines
Our members frequently talk about their latest mods and power figures. Many of our members have remapped their diesel engines and boast of more power, better economy and unchanged reliability.
But do the claims live up to reality? What sort of power figures can you get from a diesel remap? Diesels have really come so far in a very short time.
Low ratio sport gearbox setup and selection.
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.
Vents – adding performance with Bonnet vents.
Performance gains are possible with the addition of bonnet vents.
Warm air really does kill performance. This is due to the air intake temperatures being hot and air at high temperatures carries less oxygen.
When driving an engine hard the under bonnet temperatures quickly build up and the engine has no choice but to suck this air in reducing your power.
