911 Tuning
The Real Porsche.
The 911 represents the epitome of everything Porsche.
Together with the right mods you can improve the already impressive 911 and shave precious seconds off your lap times.
One of the most reliable supercars around thanks to the impeccable German engineering it can be loved by prestige fleet hire companies and city brokers alike.
You buy in a lifestyle when you get a 911, and you certainly get one hell of a car.
The 911 has enjoyed a long production run, giving Porsche time for you to perfect the engineering. Brands like RUF have come along and brought the 911 to new levels. The performance is obviously matched through the handling.
As the styling is different little throughout the years you get the identical emotional response from a classic 911 that you will get looking at the latest one in the showroom. A lot of our members used Porsche engines in other projects such as a Morris Minor and numerous Classic VW Beetles.
Tuning tips and articles
The 911 captured the imagination of the city brokers in the 1980 and is probably the most reliable supercars around.
The engines were built for power and the sheer reliability of the engine shows that although powerful, Porsche were playing it safe together with the power figures. So, what should be in your 911 tuning projects parts list?
The following modifications are often performed by our members, select how far you would like to go before starting.
Getting the right mods for your planned utilization of the car is important. Stage 3 (competition) mods just don’t work well on the road.
Stage 1 mods: Exhaust, Panel air filter, Remap, lighter flywheel
Stage 2 mods: Ported and polished head, Fast road cam, fuel injector & fuel pump upgrades,power clutch
Stage 3 mods: Engine balancing, adding or upgrading forced induction (turbo/supercharger), Internal engine upgrades (pistons/head/valves), competition cam, sports gearbox.
Fast road cams offer one of the biggest performance gains as far as a bolt on part goes. Don’t forget to uprate the fueling when you are boosting the power – it makes the vehicle more thirsty. Improve your cars response to the throttle having a Fuel pressure boost valve. Uprated injectors will enable you to deliver sufficient fuel to the engine. When upping your fueling furthermore you will need to get a greater fuel pump to supply it.
Porsche 911 Exhaust and Intake.
The next area for modification is the intake and exhaust. For small 911 engine sizes go with a washable panel air filter. On larger engines and turbo vehicles an induction kit will help increase power. Usually do not go with the biggest exhaust you can find – the most effective for power gains are usually between 1.5 to 2.5 inches.
Once you start tuning your 911 you will recognize that the standard clutch starts to complain so get an uprated clutch. Turbo engines are just begging to be custom remapped.You will see big power gains on most turbo engined cars including diesels setting up a remap one of the most cost effective modifications.Adding forced induction will spot big power gains but this is usually too costly to be affordable. It is much easier to bolt on the supercharger than it is to get a turbo working. It is harder to map a turbo as the boost comes on exponentially with engine speed. It is actually easier to map a supercharger because the boost is proportional to engine speed with a linear curve. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.
Porsche 911 Wheel modifications.
The advantages of alloy wheels include a lower unsprung weight and more efficient brake cooling. You change your effective final drive ratio and this will have a detrimental result on performance. That’s the downside to large alloy wheels in your 911. We understand some of our members have gone larger than this without having problems., though for this reason we may advise sticking to a maximum wheel dimensions of 18 inches
