Avoid the rush : The worst days to travel by car this christmas

christmas drivingIf you’re planning on (8)driving home for Christmas(8) this year quick tip don’t do it today!

That’s the advice from travel experts anyway, with the RAC and transportation analytics specialists INRIX suggesting Thursday 19 December is set to be the worst day for road traffic. AA predicts both Thursday and Friday will be terrible for drivers, as leisure and everyday commuter traffic combines.

There may be a silver lining, though: Highways England said around 98% of motorways and major A roads will be roadworks-free in time for Christmas. But with train chaos sweeping the nation – including ongoing cancellations, the South Western Railway strike and planned engineering work – there are also going to be more travellers diverted onto the roads.

So when are the worst times to travel this Christmas?

On Friday 20 December, roads are likely to be busy for a greater period of time, between 12pm and 7pm. AA suggests traffic is expected to peak from 4pm on Friday, with delays to journey times on some stretches of motorway including the M25, the M5 between Bristol and Weston-Super-Mare and the M6 around Birmingham. Again, people are advised to travel after 8pm.

Saturday 21 December is predicted to be busy earlier in the day, as people who work during the week set off. Traffic is predicted to worsen from 10am up until around 3pm. To avoid congestion, travel after 4pm, RAC advises. On Sunday 22 December, the picture is pretty much the same, with people advised to travel after 5pm.

Monday 23 December is set to be busy between 10am and 3pm, with drivers advised to set off after 4pm – although at the risk of hitting commuter traffic from 5pm onwards, it might be best to set off later in the evening. On Tuesday 24 December, people are urged to avoid travelling between 2pm and 6pm. If you can, set off well before 10am.

What is Mandrel Bending?

We often talk about our aluminium pipes having mandrel bends, which offer the tightest bend radius on the market, but what does this mean?

What is mandrel bending?

mandrel bent pipeMandrel bending is a method where a steel rod is inserted into the tubing as it is bent. This technique perfects the tube bend without wrinkling or breaking it at the bending point. Mandrel bending is performed by a machine such as a CNC tube bender. This bender is the ideal choice for bending thin tubing without any deformities on a tight radius and why we can offer you top of the range products.

Why is it important?

The best way to look at pipe bending is to compare it to a straight plastic straw. If the straw is completely straight, it’s very easy to blow air through the straw due to there being no restrictions. However, let’s say you decide to bend the straw 90 degrees into an “L” shape. Now, blowing air through the straw will be very difficult, as the opening at the straw’s elbow will have changed from a circle to a very narrow slit. This is exactly how the pipes in your car’s intake and exhaust system work.

Mandrel bending works much like a flexible straw. When the straw is bent, a flexible section of the straw expands to maintain the round opening no matter how much of an angle the straw is bent at. When an exhaust or downpipe is manufactured with mandrel bends, the steel is allowed to stretch on the outside of the bend and compress on the inside of the bend, maintaining the nominal pipe diameter.  Exhaust gas follows fluid dynamics so if you want to eliminate backpressure while maintaining exhaust gas velocity mandrel bending allows the hot exhaust gases to flow with less turbulence.

Our mandrel bend radius

Our mandrel bends have the tightest bend radius on the market; most of the mandrel bends are 1.2D. They have been specifically designed to avoid the issue of wrinkling along the inside of pipes and tubing, during their manufacturing process. The mandrel stays in a fixed position as the outer radius of the tube experiences pressure, causing the pipe to stretch into the desired bend. Overall, maintaining the shape that we have to offer you.

As mandrel bending is one of the most accurate and cost-effective metal forming processes, our pipes are suitable for almost anything. From, joining hoses for Intercoolers, Radiators, Air induction, Superchargers, intercooler systems to making any D.I.Y system.

Our Products

Our team of experts deliver high-quality results to our clients needs with a huge range of aluminium mandrel bends which are polished and ready to go. Whatever you need, we have the pipes for you.

Driving in the EU after Brexit – whats the score

I know no one wants to hear the word Brexit ever again! But if you love driving then you really do need to pay attention to just one little part… driving in the EU.

If there is a no-deal Brexit, you will not be allowed to drive in the EU unless you have all the correct documentation.

  1. Driving Licence and IDPs

The first element is pretty obvious you will need your UK driving licence to drive in an EU or EEA country. This one doesn’t really change, you need to make sure you have a full, valid driving licence before stepping behind the wheel abroad.

The additional element is that you may need one or more international driving permits (IDPs), depending on which country you’re going to or through. To find out what you need you can check the governments own guidance here.

  1. Insurance

You will need to carry a motor insurance green card when driving in the EU and EEA. To get this please contact your vehicle insurance provider 1 month before you travel to get green cards for your vehicle, caravan or trailer.

  1. Registration documents

If you’re taking your vehicle to the EU for less than 12 months, you should carry one of the following documents with you:

  1. GB stickers and number plates

You should display a GB sticker on the rear of your vehicle. You should do so even if you currently have a number plate, which includes the GB identifier. If you do not have this in place you could receive an unwanted on the spot fine whilst driving in the EU.

So there it is. We won’t say the dreaded word again but in the event of a no deal B****t you will know what to do.

Technologies that everyday cars inherited from race cars

Modern cars benefit from technology, which has been honed over decades of competition. Some innovations started with race teams looking for an advantage, others originated outside of racing but proved their effectiveness on track. All these tests and tweaks make cars better.

Here are some race technologies that migrated into our cars:

All-wheel drive

Although a few road vehicles and race cars existed with four wheel drive before it, the Audi Coupe Quattro was the first with an all-wheel drive system. The Quattro was built to dominate the World Rally Championship. Engineers bet the extra traction of all-wheel drive would be advantageous on the many unpaved, and sometimes snow-covered rally stages. The Quattro proved them right, winning the championship in 1983 and 1984.

Meanwhile, the WRC embraced all-wheel drive and never looked back, paving the way for cars like the Subaru Impreza WRX and Mitsubishi Lancer Evolution. The biggest advantage of all-wheel drive systems is their superior traction but sports cars take advantage of the additional traction even on dry surfaces to achieve faster acceleration times.


Turbocharging didn’t start in race cars, but Turbocharged cars didn’t make much of an impact until they went racing. This began in earnest in the 1970s, when Porsche launched its 917/10 and 917/30 Can-Am cars, and Renault brought turbo power to Formula One. It was that era of racing that paved the way for turbochargers to really go mainstream in road cars. Turbos are still used for performance, but automakers increasingly use them to downsize engines in the name of fuel economy. Turbochargers allow smaller engines to produce more power.

Semi-automatic gearboxes

Gearboxes used to be a simple choice between manual or automatic, that was before racing teams found a performance advantage in transmissions drivers which can shift themselves without a clutch pedal. Eliminating the clutch allows transmissions to shift faster, so it was only a matter of time before the technology became commonplace in both race cars and road-going sports cars.

Anti-lock brakes

Anti-lock braking systems (ABS) were used more commonly in aircraft before cars. In 1961, a variation of the system was fitted to the Ferguson P99 Formula One car but this wasn’t very successful in F1. It only won a single race, and driver Stirling Moss didn’t even use the ABS, preferring to modulate the brakes the old-fashioned way.

The Ferguson P99 was ahead of its time. Its ABS was mechanical; it would take electronics to make ABS truly practical. Today, it’s illegal to sell a new car without ABS in the U.S. However, ABS is not allowed in Formula One. It’s one of many driver aids banned in the series.

Our Custom Fabrication made simple

custom silicone hose with toolingWe get lots of messages from our users asking about custom hoses. As much as we appreciate all of the love, we thought we would take a moment to clear the process up.

Many messages we receive include questions like ‘If I send you OEM hose can you make one the same’ or ‘I need a set of hoses for XYZ model of car’. As much as we would love to help all of the people who get in touch it simply isn’t viable to make most of the requests we get.

The main thing to remember with our custom manufacturing is that there is a minimum order of 20 + tooling. This means that if you were looking for your own vehicle you would need to pay for the creation of the tooling plus 20 sets of the same hose when you only need 1. As you can imagine this would make the project financially viable. We are not in the business of ripping people off.
