Tuning the Dacia Logan

"Cheers for reading this Dacia Logan tuning guide."

The Logan is a awesome car modification project to have. Plan ahead and research Logan tuning to avoid making the usual disastrous mistakes we regularly .

Our aim here is to detail the best approach to Logan tuning and point out the best upgrades. Dacia Logan offer good returns when tuned and with a few sensible sports mods like a remap, turbo improvements and camshafts you will increase your driving fun.

Handling/Suspension upgrades

Many Logan owners uprate the handling of their cars with sports suspension upgrades as a priority, this will certainly increase your enjoyment of the car.

We found that most Logan factory suspension setups need tweaking, a few degrees of toe out for cornering or toe in for stability, 0.9 to 1.5, and slight negative camber will often benefit your cornering and handling.

Drop the car by as much as 27mm - 43 mm. and fit modified stiffer dampers, bigger drops will need other modifications in most instances.

Our aim in Logan engine tuning should be to increase peak power and Torque at the top end.

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.

Engine Tuning.

These mods motorsport kits are usually fitted by our members, decide how far you want to push your car before you get started.

Getting the right uprated modifications for your planned usage of the car is essential. Stage 3 motor sport parts just don't work well on the road and will make the car undrivable.

Modifying to Stage 1:

 Suspension upgrade (drop 27mm - 43 mm.), Panel air filter, Sports exhaust, Alloy wheels, Lighter flywheel, Remap.

Modifying to Stage 2:

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

Modifying to Stage 3:

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

Peak power is all well and good but for a daily driven car you need a long torque band and perhaps extending the rev range.

The whole point of our articles is to give a starting base of tuning modifications and point you in the right direction, our forum is where you can ask for more detailed advice and tips on your car tuning project, the best sport modifications and all aspects of modding cars.One of the biggest mechanical performance parts you can do to your NASP engine is to fit a fast road cam .

The exhaust and intake durations play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car awkward to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a remap to fully realise your gains.

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

If you find you suffer from flat spots and surges after your uprated upgrades you should check the fuelling and try a higher octane fuel as well. Higher capacity injectors will enable you to supply sufficient fuel to the engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Logan's uprated injectors.

Intake and Exhaust Tuning.

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

Maximum power gains come from a full induction kit with a cold air feed on heavily tuned engines, this can be sited within an air box but a panel filter should suffice for most applications. TorqueCars suggest you use a panel air filter as these are easy to clean and maintain and generally perform better than paper ones.

Do not go with the widest exhaust you can buy this will slow up the exhaust flow rate - the best exhausts for power gains are usually between 1.5 to 2.5 inches. It is the shape and material more than the bore size.

Airflow through the head can be dramatically increased with some professional flowed (porting and polishing). These should match and be setup to take into account any other engine mods. In nearly all cases of Logan tuning your clutch will start to slip and this needs to be uprated - read our overview on clutches for more information. The best mods we recommend for your Logan are fast road camshaft, remap, induction and exhaust, suspension.

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 fully release the potential power of the engine.

We've also come across some owners experimenting with twincharging conversions and making some seriously high power gains.

Adding forced induction will see large power gains but this is usually too expensive to be cost effective. It is usually simpler to add a supercharger than it is to fit a working turbo. It is harder to map a turbo as the boost builds exponentially with engine speed.

The nice proportional boost and rpm characteristics of the supercharger make them easier to map. To cope with forced induction you will usually need to decrease the engines compression ratio .

Alloy wheel upgrades.

The benefits of alloys include lowering your unsprung weight and more efficient brake cooling. Further improvements can be made to your cars handling with the addition of track legal slick tire. The downside to large alloy wheels on your Logan is that you're changing your final drive ratio and this will have a detrimental effect on acceleration and performance.

Due to this fact we would advise sticking to a maximum wheel size of 16 inches, although we know some of our members have gone larger than this with no problems.
