In the UK, the C900 Turbo is an 8V - the 16V'ers are usually called 900 Turbo 16V. I'm not *that* fussed about a performance increase. I'm very happy with the boost curve and the delivered power. I have actually had the boost turned down due to an over-boost problem. I presume that with a more more responsive dump valve the boost can be upped again? The noise factor is kewl - I can pfwooosh like the Escort RS Turbo nuttaz :) Nah, not that bothered - I'm more keen on prolonging the life of the turbocharger and the car generally. The 155HP is good enough for me - it makes a nice motorway cruiser, which is why I bought it. Out of interest, what can be done to increase performance? Thanks, Paul
