 The Keith Edwards Motors car is running a 2.2L 5 cylinder 20v engine from an S2 that produces 750HP at the flywheel at 1.9 BAR of boost (560 kW and 27 PSI for those of you pulling out your calculators) from the GT3582R Garett turbo. The engine supports this power with the aid of Wossner pistons and forged conrods, Fardon crankshaft, Supertech valves, ported and polished heads and solid lifters to match the larger, more aggressive cam profile. All of this is controlled by a MoTeC M800 ECU and C125 dash display/logger with a Drag Power Systems 6 speed sequential helping put the power to the ground via the Audis 50/50 split open diff 4wd system.

On face value it looks like this is just a shortened Quattro, however interestingly it takes 2 donor cars to create a replica like this with an Audi 80 making the front end due to a more preferred windscreen angle, and a Quattro tail end. The rear venting system needed some slight adjustments with part of it being blocked off to force more air over the rear mounted radiator to help keep things cool in the less dense air of Pikes Peak.
