Of note, the compression ratio is 10:1 (which is why it tends to knock unless it gets high RON fuel), and there are 4 valves per cylinder. Peak torque is at 4000rpm, and peak horsepower is 32kW at 6800rpm.
Current Mods:
Modifications Include grilled blocking, full Al undertray, left external mirror removal, rear skirts, partial boattail, front and rear deflectors. This adds up to a drag coefficient of 0.245 down from the stock 0.37 (estimated). Tyres inflated to 50psi.
Planned Mods:
Front skirts, that's about it. Maybe larger diameter tyres.
