I now have two supercharger kits available, as per those described in the online shop. One polished and one not. Frankly they both look awesome.
I believe supercharging is the way to go if you're looking for power from your XPAG. A 1350 engine with a standard head can produce serious horse power when blown and saves the expense of a Leystall head and boring the engine. I'd also wager it's less likely to go wrong.
The kits are extremely simple to fit, having been factory designed for XPAG and come with all the relevant belts, fittings and pulley for 6 lbs boost (suited to fast road use). Higher boost set-ups will be available shortly. I will also have full technical specifications and be able to advise re: power-output. All technical data is being collated at the factory and under great scrutiny.
These will be +VAT in the future, imported to meet demand. It's a niche product but offers a straight forward and economical solution to building a race engine or a reliable fast road setup.
