well taking a look on the pumabuild website, instead of just wondering lol, probably something along the lines of this:
Stage 6 Big Turbo 360bhp/400lbft
A very powerful power upgrade for the Focus ST once again we are leading the way with the Focus ST. We have fitted a larger GT28 Turbo and still retained the strong low down power and torque. The GT28 turbo starts to produce boost as low as 1,500rpm, at 2,500rpm there is 1bar of boost and at a little over 3,000rpm there is 1.2 bar of boost. The standard turbo runs out of breath at 4750rpm and above the small stock turbo simply cannot supply enough air to the large 2.5 litre engine. The GT28 is a flexible turbo and can supply enough air to the engine even at high engine speeds so peak power is an easy 350bhp. The GT28 Turbo on this engine could produce 475bhp but we have limited it to 350bhp. So this is a turbo working to 70% of its capability so it will remain reliable. The drive of the car remains the same you will sill be able to go to the shops and pick the kids up from school but with the added bonus of having 360bhp to play with. Figures are all dyno proven on independent rolling road!
