Porsche Cayman Tuning

"Thanks for reading this Porsche Cayman tuning tips."

We outline options for your Cayman tuning and report on the ultimate modifications for your car. Porsche Caymans are awesome to work on and with carefully chosen modified tuning mods you can dramatically maximize your driving opportunities.

The Cayman is a good car modification project to execute. We see car enthusiasts wasting money on their Cayman doing the wrong mods and then having to start over. Follow our tips to avoid making the common mistakes

Handling/Suspension upgrades

Improving the handling for car enthusiasts first priority in your Cayman tuning project.

We found that most Cayman factory suspension setups need tweaking, a few degrees of toe out around 1.5, and slight negative camber will substantially enhance your cornering and handling.

We suggest that you fit performance suspension and lower the car by 24mm - 44 mm. Larger drops require arch work - especially on models already equipped with performance suspension.

Turning our attention to the engine we need to get a bit more torque out of the top end.

Spending a little money on the right engine and handling parts could transform your car into a high performance car.

Sadly with smaller engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

Tuning modifications.

Typically these motorsport modifications are usually fitted by our members, decide how far you want to push your car before you get going.

Getting the best sports parts for your planned usage of the car is vital. Stage 3 (competition) mods just won't work well on the road making the car difficult to drive.

Stage 1 mods: Suspension upgrade (drop 24mm - 44 mm.), Panel air filter, Sports exhaust, Lighter flywheel, Remap, Alloy wheels.

Stage 2 mods: fuel pump upgrades, Power/Sport clutch, Ported and polished head, high flow fuel injector, Fast road cam.

Stage 3 mods: Adding or upgrading forced induction (turbo/supercharger), Engine balancing, Sports gearbox, Internal engine upgrades (pistons/head/valves), Competition cam.

Your aims when modding your car should be a flat and wide torque output. You want to avoid sending all the torque to be at the top end unless you are creating a motor sport car.

In this article we shall give a little insight into the world to the best modifications for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance mod.Fast road cams offer one of the biggest power gains for your money as far as a bolt on performance parts goes on a NASP engine.

The exhaust & intake valve durations play a big role in your cars power band, but be careful here, getting this wrong can upset the idle and make the car challenging 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.

Don't forget to ramp up the fuelling when you are increasing the power - it makes the car more thirsty.

Using high octane petrol is another option if you find you are suffering from detonation or premature ignition on your Porsche project after fitting other performance mods. Larger injectors will enable you to supply sufficient fuel to the engine.

A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel.

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car with over 30 percent more power and are finding that the standard air intake has become a limitation.

Derestricting the airflow into the engine is a primary goal of tuning so get a better flowing air filter if you find that the car is running lean only if you find the car is running lean. Induction kits can sound sporty but due to the warm air in the engine bay they will not really increase power and actually rob you of power.

Sports exhausts can usually air flow out of the engine but do not go too large or you may end up will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

Getting a professionally ported and polished head with larger valves can fully maximise your power gains. When you heavily modify your Cayman you will usally see that the standard clutch starts to suffer so get an uprated clutch. The best mods in our experience for your Cayman are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

NASP engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A remapped turbo will give large power gains and take full advantage of the strength of the block. Adding forced induction will see massive power gains but this is usually too expensive to be cost effective. Turbos are usually harder to add than a supercharger. It is more challenging to map a turbo as the boost builds exponentially with engine speed.

It is more straightforward to map a supercharger because the boost is directly proportional to engine speed on a linear curve. Adding forced induction will nearly always require a lower compression ratio or water injection.

Alloy wheel upgrades.

Because alloy wheels are less heavy they improve performance and they help to cool the brake disks. We can't go into too much detail here about tires but they are how the car puts the power down on the road so are a critical choice. directional tread pattern tires work well on Cayman, and make a big difference over budget tires. Large Cayman alloys can decrease performance. If you get big alloys you will be changing your final drive ratio.

Although some people have gone larger than this without issues we would restrict ourselves to a 18 inch rim size as the maximum.
