Powertec EnginesGSX-R Series I 4

Suzuki’s acclaimed GSX-R series of engines are the basic building blocks of all Powertec racing engines, incorporating state-of-the-art technology with an unrivalled power-to-engine weight ratio.

The GSX-R1300 (Hayabusa) is widely recognised as the world’s fastest production motorcycle, with a top speed of 194mph (312 km/h.) Distinctive features of the Hayabusa engine are its abundance of low-end torque and strength of the components, making it an ideal powerplant for four-wheel applications.

Powertec have designed, manufactured and developed a wide range of unique engine and gearbox components, which are available to customers to enhance the power and increase the reliability of their race engine:

› Cylinder head race porting and polishing, including oversize valve seats

› Performance camshafts, in a range of reprofiled or billet cams

› High-strength roller ‘race’ cam chains› Race valve gear including titanium retainers,

race valve springs and one-piece stainless steel valves

› Cosworth lightweight, high-performance two and three-ring pistons

› Oversized cylinder barrels with Nikasil plated bores

› Arrow high-strength forged steel connecting rods› Arrow billet long-stroke crankshafts› Lightened, polished and knife-edged crankshafts› High-strength clutch components including billet

clutch baskets/back plates, race springs and steel clutch centres.

› Uprated gearbox components, including heavy-duty steel shafts, stronger gears, close ratio six-speed and three-speed gearbox kits

› Dry sump systems which eliminate oil surge and improve efficiency

› Extra-high-volume oil scavenge pumps› High-strength billet clutch slave cylinder › Life Racing ECU and wiring looms

03. Powertec GSX-R Forced InductionThe GSX-R Hayabusa is the most popular donor bike engine for turbocharging. Powertec have developed a three-stage system designed primarily to work in track applications. A Stage One system can be fitted without any engine work, and will produce 300bhp with around 6 psi of boost. Stage Two upgrades require engine modification, but will produce 350bhp with 12 psi of boost. Power can be increased to 400bhp with the addition of a chargecooler and further modification of the engine.

› Rotary-vane Garrett AIResearch turbo› Blow-off valve› Injectors (including wiring adapters)› Billet fuel rail and fittings› Performance fuel regulator› Twin-stage boost controller› Chargecooler upgrade
