The Audi RSQ3 is Audi’s effort to put a wolf in a sheep’s clothing. On the outside it looks like a pumped up Q3 but on the inside it houses a 2.5 liter TFSI RS3 engine, all wheel drive, big brakes and a seven speed DSG transmission. It is most definitely not a soccer mom car. Even less so when upgraded with a big Xona turbocharger, included in the RPCMotorsport Stage3 turbo kit. The kit itself is designed to max out performance at 780hp on a built RS3 engine. To keep the engine stock, we limited boost to under 23psi and added AEM’s water-methanol kit to improve fuel quality and anti-knock at high boost.
Maximum performance was 435whp at 23psi, leaving lots of space for more power to come when the engine is upgraded with pistons and connecting rods.
