It is with great pleasure that we introduce our latest project. Bradan has been commissioned to build a twin turbo conversion for a 2006 Lamborghini Gallardo SE. The goal of this project is to reliably increase the engines power output to 750-800 all wheel horsepower using 93 octane fuel. The engine will be rebuilt and reinforced internally to handle the increased boost pressure. A turbo system will be designed and engineered to build power in a similar fashion to the OEM power curve. The full process will be documented step by step to show what is involved in such a project and show our capabilities. We hope you enjoy watching the process during this winter.

This is one of the many items that we are redesigning and manufacturing to reinforce the internals of the engine. With a full aluminum block construction, we were concerned about the extra stress forced induction would create. We designed cast iron cylinder sleeves to reinforce the cylinder walls. The block is going to be machined to remove material which will allow these sleeves to be pressed inside.

Connecting rods

Although our power goals are relatively conservative, we decided to reengineer all engine internals for increased strength for long term durability. The connecting rod beam was changed to a forged 4330 H-beam design. Two holes were machined in the rod end for pin oiling. Hardware was upgraded to a 285,000 ksi rated fastener.

Pistons

We had forged pistons made to lower the compression ratio to 9:1.
