It would also be worth reading our 911 tuning articles to get a full grasp of the pros and cons of each type of modification. Please join us in our forumto discuss the 911 options in more detail with our 911 owners. For this reason we would advise sticking to a maximum wheel size of 18 inches, although we know some of our members have gone larger than this with no problems. The downside to large alloy wheels on your 911 is that you alter your effective final drive ratio and this will have a detrimental effect on performance.
The benefits of alloy wheels include a lower unsprung weight and more efficient brake cooling. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation. It is easier to map a supercharger because the boost is proportional to engine speed on a linear curve. It is harder to map a turbo as the boost comes on exponentially with engine speed. It is easier to bolt on a supercharger than it is to get a turbo working. Turbo engines are just begging to be custom remapped.You will see big power gains on most turbo engined cars including diesels making a remap one of the most cost effective modifications.Adding forced induction will see big power gains but this is usually too expensive to be cost effective. When you start tuning your 911 you will find that the standard clutch starts to complain so get an uprated clutch. Do not go with the biggest exhaust you can find - the best for power gains are usually between 1.5 to 2.5 inches. On larger engines and turbo vehicles an induction kit will help increase power. For small 911 engine sizes go with a washable panel air filter. The next area for modification is the intake and exhaust. When increasing your fuelling you will also need to get a bigger fuel pump to supply it. Uprated injectors will enable you to supply sufficient fuel to the engine. Improve your cars response to the throttle with a Fuel pressure boost valve. Don't forget to uprate the fuelling when you are increasing the power - it makes the car more thirsty. Typical stage 3 mods: Engine balancing, adding or upgrading forced induction (turbo/supercharger), Internal engine upgrades (pistons/head/valves), competition cam, sports gearbox.įast road cams offer one of the biggest performance gains as far as a bolt on part goes.

Typical stage 2 mods often include: Ported and polished head, Fast road cam, fuel injector & fuel pump upgrades,power clutch Typical stage 1 mods often include: Exhaust, Panel air filter, Remap, lighter flywheel
It is one of the most costly upgrades but provides the best gains. Upgrades to turbochargers and superchargers - forced induction is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power.
