SKN Tuning - Another Supercharger kit

Hi All,
Been doing more trawling through the web and have found SKN Tuning which appear to be a German company. They have Stage 1, 2 and 3 Supercharger kits available but looks like you would have to sell an arm and a leg to get one so really makes the Carlicious kits look good value for money.

Figures are based on the 20 valve 170bhp model and do show better performance gains than the Carlicious kits.
Standard figures for this model are 170bhp and 220Nm Torque;

Stage 1 = 246bhp (+76bhp) and 295Nm Torque (+75Nm) £4,610.13
Stage 2 = 276bhp (+106bhp) and 327Nm Torque (+107Nm) £6,002.13
Stage 3 = 300bhp (+130bhp) and 363Nm Torque (+143Nm) £7,133.13

Anyone got a spare £7,000 to lend me???

That is a lot of money

that is quite a bit more money, im sure at a small extra cost, Carlicious parts would put a smaller pulley on the charger, increasing the rpm of the charger and therefore the boost aswell.

im sure they would...because i've asked them before.   
so i know i can up the boost later on if i want to.
