Formula 3 Team Choose JC Weldfab

Silverstone based Formula 3 team Performace Racing are the latest professional race team to choose JC Weldfab for their fabrication and welding work.

Performace Racing will be running 3 cars in this years German Formula 3 Championship and asked the guys at JC Weldfab to undertake some work to help them get prepared for another successful year.

The jobs included re-working the exhaust tailpipes as they were originally slightly too close to the bodywork, repairing an upright and re-working the water radiators to twin pass.

The main job was to make a new tyre trolley to accomadate the 3rd car, this was made similar to their original trolleys but with a few extras including a mounting point to house the nitrogen bottle, an aluminium tray to lay some plastic boxes for other spare parts and and aluminium panel which slots onto the top tube to allow the engineers to put there laptops. The trolley was beautifully made from stainless steel and was mirror polished to finish.

Michael was very happy with the end product, commenting “We believe there is a healthy market for manufacturing pit equipment for professional race teams so it was great to be approached by Performance Racing and we are confident it will work great whiltst also showcasing the quality and diversity of our work. JC Weldfab wish Performace Racing all the best for the 2012 season”.

Time Attack Evo 8

Marc Kemp will be racing in the Time Attack Series in 2012 aboard a Mitsubishi Evo 8 in the Club 4WD class and is looking forward to a successful year.

Having already come to JC Weldfab for a T45 roll cage in 2011, Marc returned to us for a custom made intercooler, boost pipes and exhaust system. Jon, Michael and apprentice Sam all visited Tractive Solutions in Leicester, where the Evo is being prepared, to measure up for all the work to be undertaken at our Wellingborough based workshop.

First up was the intercooler, the core being manufactured to fit perfectly in the space available in the bumper whilst also ensuring it was big enough to handle the volume of air it will be exposed to. The end tanks were expertly fabricated to optimise air flow and were fully TIG welded.

Aluminium boost pipes were next up and attention to detail was critical to optimise air flow and make sure there was plenty of clearance. Marc experienced problems in 2011 with boost pipes popping off so we reccommeded using Wiggins clamps instead of silicon hose and jubilee clips, as the Wiggins clamps would prove ultra reliable as proven by such teams racing in World Rally and Formula 1.

Finally the exhaust had to be made from the manifold back as a tubular manifold had already been fitted. The downpipe had to be fabricated, and as space was at a premium it had be carefully made to ensure there wouldn’t be any clearance issues. A flexi joint was then welded to the downpipe to allow for any movement , then the system followed down the centre into a custom made silencer box, packed with a specific sound deadening material that would handle the heat it will be exposed to. It was then finished very neatly with a side exit tailpipe. As with all the JC Weldfab made exhaust systems this was fully TIG welded and “back purged” to optimise strength and also a smooth inner weld for perfect gas flow.

The first round of Time Attack is this weekend (5th May) at Cadwell Park in Lincolnshire.

Michael, Jon and Sam wish Marc the best of luck in 2012 and beyond!

BMW HP2 Sport Exhaust System

Since the birth of JC Weldfab 18 months ago we have begun to establish ourselves in the motorsport world, however the majority of our work is race/fast road car orientated. Another particular passion of ours is bikes, so this next job was certainly an interesting challenge, which was undertaken by Jon who has many years of previous experience in modifying and tuning bikes for the serious enthusiast.

We took delivery of a BMW HP2 Sport from Sandbar Composites and set about making the rear section, however unlike the standard system we split into a twin pipe prior to entering the silencer box that in turn was also bespoke made by hand. This meant making full use of the perforated tube inside the box which was wrapped in stainless wire wool to protect the sound deadening filler. The whole system was fully TIG welded and back purged maximizing strength and performance. We also made additional bungs which bolt into the back of the silencer box to reduce the sound by a further 3 decibels to comply with any strict track day regulations.

This was an interesting challenge in that the silencer box was a unique shape, however as always we rose to the challenge and the finished product looked and sounded fantastic.

Jon commented, “Being a keen bike enthusiast myself I really enjoyed making this system and it certainly tested my patience on occasions! I’m chuffed to bits with the final outcome and there has been a lot of positive feedback since so that’s always a good sign.”
