How would you like an actual Cosworth Formula 1 piston to display in your home or office? We have for sale one of the actual pistons that was fitted to one of the Cosworth CA2010 engines from the 2013 Formula 1 season.
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 season, bowing out at the end of 2013 after powering the rebranded Marussia team.
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 Piston
The piston was perhaps the most highly-stressed component in the engine. It had to withstand huge forces over a sustained period of time. At speeds of 20,000 rpm the piston moved up and down over 300 times per second. That’s more than 30 times in the blink of an eye! Despite the incredible forces that it had to endure, it also had to be as light as possible.
The CA piston was the culmination for Cosworth of decades of experience in piston design. As such, this piston contained several important design features. For example, a single compression ring replaced the traditional top and second compression rings. The undercrown received additional machining to remove excess material, with buttresses whittled away to the bare minimum. The skirts were DLC-coated to give additional wear resistance, creating a gloss black appearance.
- Diameter = 98 mm
- Height = 40 mm
- Weight = 227 g
- Material = High strength aluminium alloy
(Please note that these pistons have been run and hence will have some carbon deposits on the crown along with discolouration on the undercrown. The carbon deposits are easy to remove if you want to restore the crown to its original polished finish like the piston pictured here.)
