What would be a rough DIY build cost ?
What power gains can be achieved ?
Anyother useful info / opinions ?

You will need:
Ebay special supercharger from a jag for £200 - £750
Extra injectors and seperate controller box like the turboed 2.9 cars have
Solid brackets to mount the supercharger
Pulley £200 - £300
Pipework £100 - £200
After that you might want to look at intercooler and even more pipes, different breathing system and then a after market ECU to control it. Power wise its very hard to say and its torque you want from such an engine and you will gets lots of that and at a very low RPM. Mine for example produces 300lb/ft of torque at 1800RPM (Standard 2.9 gives 172 max torque) then rises to 350lb/ft of torque at 3000RPM. Fitting a supercharger can cost a bit but the car is so smooth and will pull very hard at very low RPM in high gears so its great when driving down motorways etc.
