A 200 bhp R300

This car has been upgraded by DPR Motorsport to 200 bhp (175bhp standard) using the Caterham Stage One roller barrel upgrade accompanied by a new Caterham developed ecu map. Tony Bennett ran in class B and came third in class with a lap time of 52.423 seconds - the class winner had a lap time of 51.585 but was driving a highly tuned 1,800 cc K series. Second in class was a Hyabusa engined 1600.

Jonathan Packer driving a standard R300 came 5th in class with a fastest lap of 52.631 and both drivers beat a number of the on-paper more powerful Caterham 1,800 K series engined R400 (14 cars ran in class B) demonstrating the much enhanced on-track performance delivered by the R300 in standard form and also what can be achieved with a relatively modest power increase combined with the new Avon ZZR tyre.

Impressive on-track performance

DPR team principal David Rowe said “We are extremely impressed by the Caterham Stage One upgrade for the R300. Using the standard cams this upgrade provides a good increase in peak power. Through the race driving range, the increase in torque and bhp both have a higher gain than the peak bhp increase of 14%. When combined with the increased grip of the new Avon ZZR tyres the result is a very drivable race car.”
