Looking for performance alternatives to these can often free up some of this lost power but most drivers will need to keep their car street legal.ĥ) Porting, polishing and valve seat angles. Large capacity engines and turbo engines will respond well to induction kits, performance air filters and performance sports exhausts but there are many pitfalls and things to note with this mod.Įxhausts are fitted with catalysts or particulate filters which usually degrade performance. The larger the engine and the higher it's RPM range the more dramatic the power increase will be. Improving the airflow through the engine will usually result in a power gain. Setting this up with a vernier pulley gets the maximum power from it and puts the power where you need it.Ĥ) Intake and Exhaust upgrades.
#BEST CAR TUNING COMPANIES MOD#
There are some catches though, as this mod will typically push the power up into the top end of the RPM band.Ĭhoosing the right cam is an art and should ideally take into account any other mods you have performed. A new camshaft will dramatically alter the intake and exhaust durations and can also make a large difference to your engine power. Read our guides to chip tuning, tuning boxes and remapsģ) Fast road cams. NASP engines do not respond as well to new engine maps and will usually only gain around 10% more power. On turbo engines in particular you can see power gains of around 30-40% without compromising reliability. Changing the timing parameters of the engine and altering the fuelling and boost bring large power gains. For larger gains you could go with a big turbo conversion but this will require a lot of work.Ģ) Remaps and Chip tuning. Upgrading an existing turbo is relatively easy and there are bolt on direct replacements around. Twincharging is also becoming popular (the addition of supercharger and turbo).
Read our guide for more information on this. But without a doubt is one of the best ways to get a significant power gain. Adding a larger capacity turbo or adding forced induction to a NASP engine provide the largest power gains.Īdding a turbo to a NASP engine is a major engineering feat and will cost a small fortune. Feel free to join our forum to discuss tuning mods in more detail.ġ) Turbo upgrades. Please browse our many articles for our unbiased opinions and tips on all aspects of car tuning and car modification. Just because a modification is popular it does not necessarily mean they're effective, or that they are truly a performance modification, so we're sticking to the tried and tested power gain methods. Each tuner has their own preferred mods and on different engines you'll need to employ a slightly different approach but this is general common sense guide. Here are our top 10 performance modifications and links to articles that cover them in more detail. Read our Top Ten car performance modifications and explore our tips and 'how to' articles.
