Throughout the 2007 HKS Drag series the JPS Motorsport Supra got progressively faster. The car became more powerful and better prepared. An official 8.5 @ 151mph pass and an unofficial 8.2 @ 154mph meant that the original Orange and Carbon Supra was only legally able to achieve an 8.5 with the roll-cage.

This was then a dilemma. The orange supra was running 1200bhp and needed this power to run 8seconds as the weight of the car was 1400kg. So to go faster Leon needed a strengthened cage which would require more weight. This was then thinking time for Leon, “a new car”? Yes a new car, a new build and more power was the outcome. This time it would be built from the outset to allow us at JPS for plenty of improvement. The Orange Supra was then turned into a donor for the new build and another Supra shell was obtained to form the basis of the new car.

The new shell was then delivered to Webster Race Engineering, a team of quality Drag car builders in the UK. In record time, between 6 weeks the Supras body shell transformed into a full strengthened Drag chassis meeting the 25.1 specification, which in layman’s terms equates to the car certified to run 7.49secs or faster.

The shell transformation involved cutting out the floor to receive a fully tubbed rear section and installing a latticework of strong lightweight chromoly tubing. Over the frame work was a carbon bonnet, carbon tailgate, carbon front wings and carbon doors taken from the Orange Supra this was just to restore the original Supra bodylines.

Whilst the chassis was at Webster Race Engineers under construction, back at JPS Leon was building a new engine. After successfully bending two HKS crankshafts in quick succession and running most of the 2007 season with a modified stock crankshaft, Leon has built the new engine with a custom crankshaft machined from high-strength material to ensure the bottom end is virtually bullet proof.

The Supra has a MoTeC M600. The ECU is mapped by Dave Rowe (EPS), who has proved to be an invaluable addition to the project. With the availability to pore over the data and tweak individual parameters to get maximum performance without sacrificing reliability is what Dave does best. It’s a calibration that has served Leon well and will no doubt bring better results in the future.
