    to work around this problem, you could change the management of the turbo, maybe by changing the same to increase the flow rate of the air, touching the map that manages the variable geometry ? can enhance or reduce the decline after 3000 rpm?
    no, you can? solve, but what? doing we should decrease the life of the turbine, in order to have a shot at 4000rpm (good) you have to mount the turbine on the pi? big (especially on the discharge side) and have a system of injection is effective, of which this car? ? gi? with the series...

    I have a friend who reviews the change and creates from the full-turbochargers and parts attached to them, there are certain parameters to be respected in order not to have problems, for a hypothetical change of the turbine to the original, he performs processing of the 2 nuts, intake and exhaust, replacing the original post with a titanium treated specially and sotituisce all components such as bearings and bushings, "cos? they are called" with other over-sized, in addition, the transfer of the oil that lubricates the spindle, is completely revised and optimized, in this way, for example on the drive in question you can? safely hold a pressure of 2.5 bar constant with a peak of up to 2.8, not bad I would say, logically, the system intake and exhaust system needs to be revised and optimized to the best to be able to exploit the full potential of the turbo

    I have changed the map how would I do soft for the type of mod to be times that you want to do, see how I did it, let's say that ? generic more or less

    that the basis used to arrive at (2.5 bar) constant? and before you ruin?
    I are generally pessimistic about the processing of the turbines, are an organ pi? complex than it seems, it is not enough to widen a bit the pipes, put a impeller pi? big then maybe you get to the chock of the speaker...

    has a its internet web site and is preparations also very high, the balancing ? made from a base of 300,000 rpm to 400,000 for those pi? pushed to the opposite of many is made 2 times, only the first post and then the entire core axes, I'll just tell him that he has a dobl? with 2.5 bar constants and 300,000 miles, never a problem ;-)

    very hamper also cash advances, then you work those if you look at the map that you have after 5000 rpm, the torque required ?0
    with the criterion laid down that the original value of advances limits the power? for me ? a consideration not credible... the designer has imposed those values to inject at least 75 mm^3 in the useful range of combustion that can afford to turn on the flow injected without fumosit? without the production of unburned and according to a suitable motor? the noise... the accounts will not come back, and you seem to have a greater? high why? anyone who tells you that are not in p? high to continue to inject some degree after the tdc?.... now if we increase the flow rate within a determiato range is not c'? need to adapt them otherwise ? must ... play turbo pressure must also be good for? not always ? enough depends on what you want to get... the advance ? an ugly beast, if out of control you trvi von cylinder pressures and exhaust temperatures that long can cause damage... especially to the exhaust manifolds ... all accompanied by a nice foot f? a nice salad..

    it also builds the impellers suction in a variety of materials including ergal, obtained from the full ;-) ask tidus, he saw some of his work, are works of art

    and true, they work fine, also, change the oil pipes to adapt lubrication and cooling to the new effort, which turns the turbine, has a shop very well stocked and serious.
