C4 Cactus Tuning

Citroen wanted to make a small SUV car aimed at millenials and came up with the Cactus.

One of few cars to have soft air bump panels on the site it clearly stands out, and some may dislike the styling but it does find many fans among the target market.

It came with 2 peppy engine choices, the 1.3 3 cylinder petrol and the 1.6 HDI 4 cylinder diesel. Both have been tuned for economy and comfort and have the potential to make more power with the right modifications.

It won a few awards along the way, Hatchback of the year (Top Gear), Production car of the year (Geneva motor show) and the Small SUV of the year from Auto Express.

The only thing holding you back in your C4 Cactus project is time, money and your imagination If you do your homework then you can create an awesome C4 Cactus but don’t be fooled there are lots of uprated parts out there that will simply not suit it read our unbiased guides first.

Do not slap on a massive exhaust and induction kit expecting anything other than more noise! Owners have reported disappointing results with those mods on the 1.2 and 1.6.

Many C4 Cactus owners uprate the handling of their cars with sports suspension upgrades as a priority, this will certainly increase your enjoyment of the car. Don’t go too low or too hard, a set of adjustable shocks will give a good range to work in and allow you to find the peak setup.

A little negative camber and toe in on the front suspension greatly sharpens up the handling.

We suggest that you fit modified suspension and lower the car by 30-35mm. Larger drops require arch work – especially on models already equipped with uprated suspension.

Our aim in C4 Cactus engine tuning should be to increase peak power and Torque at the top end.

C4 Cactus make good sleepers and fun weekend cars if you modify them and fit the most powerful engine upgrades and handling mods you can source!

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size.

Engine tuning mods.

The following performance modifications are usually installed by our members, decide how far you want to go before you get going.

Getting the right tuning upgrade kits for your planned usage of the car is vital. Stage 3 (competition) mods just don’t work well on the road hard to control in slow traffic.

Stage 1 mods: Panel air filter, Suspension upgrade (drop 30-40mm), Remap, Sports exhaust, Alloy wheels, Lighter flywheel.

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

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

You should keep as much low end power as you can and aim to get a long power band across the rev range rather than a narrow top end power spike.

The whole point of our pointers is to give a starting base of customizing upgrades and point you in the right direction, our forum is the place to go for detailed advice and tips on your tuning project, the best sport modifications and all aspects of modding cars.A fast road cam will be one of the best NASP power modifications you can do from a single upgrade to your engine.

The intake and exhaust 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 hard to drive in traffic. You’d need to follow a camshaft upgrade with other mods and finish with a reflashed ECU for the best performance gains.When pushing up the power you will need to uprate to the fuelling. More power needs more fuel.

Using high octane petrol is another option if you find you are suffering from pinking or premature ignition on your Citroen project after fitting other motorsport mods. Uprated 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.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become a restriction.

For most C4 Cactus engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of needing cold air.

Sports exhausts can usually air flow through the engine but do not go too wide or you may end up will reduce the flow rate. Stick to 1.5 inches for best results.

Getting the head flowed (ported and polished) will further help more air into each cylinder.

This is definitely a job for a professional with a flow bench. In nearly all cases of C4 Cactus tuning your clutch will start to complain and this needs to be uprated – read our article on clutches for more information. Turbo engines are just crying out to be Upgraded. You will see large power gains on most modern turbochaged cars including diesels making a remap one of the most cost effective and large modifications for your money.

We’ve also come across some owners playing with supercharger kits, and even going to twincharging applications and making some very high power gains.

Despite the large cost involved adding forced induction to a NASP engine will give large power gains. Turbos are often harder to add than a supercharger. Turbos increase power in increasing proportion to rising engine speed and this can make mapping difficult.

Superchargers, however will give a boost which is directly proportional to engine speed so is easier to map. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.

Alloy wheel upgrades.

The benefits of alloys include a lower unsprung weight and more efficient brake cooling. We should point out that although they can look cool on the C4 Cactus big alloy wheels will actually decrease your performance. The larger you go the lower your acceleration will be – this to the change in your effective final drive ratio.

For this reason we would advise sticking to a maximum wheel size of 17 inches, although we know some of our members have installed larger rims with no problems.

Tesla Gigafactory 3’s substation rises ahead of target Model 3 production

With Gigafactory 3’s Phase 1 buildout completed, Tesla’s electric car production facility continues to evolve.  Recent drone flyovers of the expansive Shanghai site have even revealed that a substation is currently being built. Sightings of workers with ABB Robotics uniforms in the area also hint at sections of Gigafactory 3 being prepared for the installation of manufacturing robots.

Wuwa Vision (烏瓦), who has been following the progress of Gigafactory 3 since it was just an open, muddy field, was able to acquire some details about the substation being built southwest of the general assembly building. The power station reportedly costs $12 million to build, and it will be tasked to supply power to the site. Reports from the area hint at the substation being completed by September, just as the main facility becomes ready for Gigafactory 3’s initial Model 3 production.

Similar to the rapid buildout of Gigafactory 3’s general assembly building, the construction of the substation is also moving at a rapid pace. The building only started construction recently, but some parts of the substation are already taking form. Considering the speed that has been exhibited by China’s workforce so far, there seems to be little doubt that Gigafactory 3’s power station will be online sometime in September.

Interestingly, the rise of Gigafactory 3 in Shanghai’s Lingang Industrial Zone has sparked the emergence of a small community of entrepreneurs nearby. Every day, food vendors, clothing shops, and other small businesses set up shop to cater to the needs of Gigafactory 3’s workers. Jason Yang, another drone operator who has been following the buildout of the electric car factory, recently took some footage of this bustling community. Just as luck would have it, the Tesla enthusiast ended up recording footage of something interesting.

Among the workers of Gigafactory 3 that were taking a break from the day’s work, Yang was able to get a video of a worker wearing a safety vest featuring the unmistakable logo of ABB Robotics, a company that specializes in manufacturing robots. While Tesla nor its construction partner is yet to release any updates relating to ABB or its machines, the presence of an ABB worker on the site suggests that the main Gigafactory 3 facility is already getting prepared for the installation of automated manufacturing equipment.

Gigafactory 3’s rapid buildout is on track to potentially set records among China’s fastest industrial-scale construction projects. Following the completion of the Phase 1 buildout in May, the facility is expected to undergo ground hardening in June. This would be followed by pipeline communication, equipment stationing, equipment commissioning, and finally, trial electric car production runs in September.
