JBS OEM Upgrades

JBS has spent enormous effort, time and resources developing the OEM upgrade turbo manifolds. The exhaust manifold has been designed in the best CAD packages availiable, for 3-D modeling and CFD analysis. By performing a computational fluid dynamics analysis, we were able to study exhaust flow, pressure drops, and fluid flow through the exhaust manifold. Multiple computer simulations were done to prove the design before we even had a physical manifold in our hand.

Once the manifolds have fully passed the computer simulations we had the cast exhaust manifold CAD model transferred to a SLS rapid prototyping machine. A nylon resin exhaust manifold was cast from the prototyping machine. With this plastic manifold we were able to mock everything up in the test vehicle before proceeding to the next process.

JBS has chosen to cast its manifolds in a very high quality foundry which is used by many OEM turbo suppliers and OEM vehicle manufacturers to ensure the castings are of the highest quality.

Also to reflect the high quality casting, JBS has spent a great deal of time researching the latest high temperature resistant cast stainless steels. These cast steels have a high nickel content, having the following properties makes them ideal for our performance manifolds: resistance to corrosion, resistance to oxidisation and high temperatures (up to 1050 ^oC), resistance to wear and erosion.

• resistance to corrosion,
• resistance to oxidisation
• high temperatures,
• resistance to wear and erosion.

This is to ensure a minimal amount of thermal expansion and an equal rate of thermal expansion to the turbo housing, this again minimises the potential for thermal fatigue (cracking).  The bolts for the fitment of the turbo to the manifold shall be supplied as they are a specific size and material to prevent stretching which leads to blowing gaskets.

The same design process is carried over into all our turbo kit components. With all of JBS' upgrade components, including: turbo out, TIP and boost pipes have all being designed, flow tested and prototype using CAD, to give the best possible performance. Our Boost pipes are available in silicone or stainless steel.
