How would you like an actual Cosworth Formula 1 connecting rod to display in your home or office? We have for sale one of the actual connecting rods that was fitted to the Cosworth CA2010 engines, raced between 2010 and 2013.
Cosworth CA Engine
The final Formula 1 engine from Cosworth, codenamed the CA, took all of the knowledge gained from decades of competition in F1 and turned this know-how into probably one of the best Cosworth engines ever. The CA was introduced in 2006 with Williams, and saw Cosworth return to the production of V8 normally aspirated engines that began with the DFV back in 1967. Capable of 20,000 rpm, the CA became the new benchmark for F1 powerplants.
After a brief sabbatical, Cosworth returned to the grid in 2010 with an updated version of the CA. By now the rules had dropped the maximum speed to 18,000 rpm. Nevertheless, the CA2010 engine was still able to produce in excess of 775 bhp. Consequently, the CA2010 was the ideal choice for both Williams and for the three new teams in F1 (Virgin Racing, Lotus Racing and Hispania Racing).
The CA2010 engine was raced for four seasons, bowing out at the end of 2013.
You can watch a short video we put together of a Cosworth CA2010 engine being pushed through its paces on Cosworth’s transient dyno at speeds of up to 18,500 rpm – just click here.
Cosworth Formula 1 Connecting Rod
The connecting rod provides the link between the piston and the crankshaft. In the Cosworth CA2010 engine, that meant that one end of the rod was rotating at speeds of up to 18,000 rpm, whilst the other end was moving up and down the bore at up to 300 times per second. The connecting rod was either being stretched to the limit, trying to stop the piston from escaping through the top of the engine, or it was being subjected to immense compressive loads from the piston which it had to impart into the crankshaft.
Hence the connecting rod is the perfect example of a component that has to withstand rapidly-cycling tensile and compressive loads. However, the weight of the connecting rod can have a significant influence in these loads, so the Cosworth CA2010 connecting rod also had to be as light as possible. The resulting design is a work of engineering art, with numerous features to remove mass or increase strength.
This connecting rod is supplied with two big end bolts, which are themselves an impressive feat of engineering. The bolt has to withstand a force that is the equivalent of 3,000 kg every crank rotation.
