Other Notes : This vehicle has been built up over the last few years by the owner for its intended track work. Starting with a RPW Stage 1 performance package with the normal bolt on packages. The factory ECU was remapped producing significant gains over stock. Like all customers though, the urge for more horsepower came after being beaten at the track against similiar vehicles.

Other mods performed over time included upgrading the drive train for future horsepower improvements as the clutch began to fail as we advised the customer after the stage 1 package. A Quaife ATB unit with the clutch and light weight flywheel upgrade was fitted up to ensure traction could be found with no further clutch slippage.

Next improvements included the front mount intercooler kit, fuel injectors, turbcharger upgrade with the intake wheel 15T upgrade only. Once done, a forge wastegate actuator was fitted to produce more stable boost control and then run up on the dyno again. Whilst this was being done launch control was activated.

Due to the vehicle being dedicated to track work, and with the known weaknesses of the conrods, horsepower and boost was limited, horsepower to 215hp at the hubs and boost to 15 psi. The vehicle was capable of going has high as 230hp on this turbo upgrade but history has shown significantly reduced reliability over 220hp at the hubs.

The vehicle has been fitted with coil over suspension, sway bars and other handling modifications, along with some improved aerodynamics which the rear wing and front spoiler shows to great effect. The interior was gutted to reduce weight and the gearshifter lifted for easier shifting when strapped in to the race seats and harnesses.

Overall the vehicle as expected drives amazingly well on the road and handles around corners like a go Kart.

Future upgrades will require forged engine internals and a Haltech ECU to be fitted as it is currently at the stock limit of the factory ECU at this point in time, although that may change in the future as we continue to delve into the Colt ECU and unlock more secrets.
