"Just thought I'd share a few picks of our latest job, this VF Maloo had just clicked over 750km when it's owner dropped it in to us for fitment and installation of a Magnuson Heartbeat Supercharger with a VCM5SC camshaft kit and a full Xforce stainless steel system consisting of 1 7/8" headers with 100 cell hi flow cats and a dual 3" cat-back with varex mufflers, we haven't pushed it to hard yet being brand new but it made an easy 381kw's at the rears with gobs of torque at 7psi, just goes to show how good these new Magnuson's are."
Taking it at face value, that's a nice effortless 500hp.
Probably close to £15k here, in parts and labour though.

I was thinking more about the fact that 1/2 bar isn't too much for the engine to cope with, either. 
8psi and something very close to 500 WHP on mine (just got it back with ARBs done). Need to get headers on and then a cam and I recon it will break past 550 with some careful tuning and 9psi. Sir Monkfish says stay at the pressure level and it will be fine so I am listening this time.

Always tempting to over-spin, and there are plenty of sad tales from those that could not resist.
