  2. Hi guys if anyone can shed some light it will be greatly appreciated.

    Firstly the car is a r33 gtst rb25det

    Mods

    Hypergear highflow (r34 op6)

    660cc injectors

    040 pump

    Power fc

    3 inch from turbo back

    Return flow cooler

    Splitfires

    The problem:

    Basically the car has been in and out of unigroup engineering when it was first put together it made 247kw at 15psi

    Had a small manifold leak so they could not push it more since fixing that and going to push more boost through it, it now only makes 220kw at 20psi but the power drops off early around 5000 rpm they suspected a restriction in exhaust or a boost leak as they retard timing to compensate for more boost but the car wont react as in the timing is not changing.

    Car is hitting the dyno again tomorrow with another cas just to rule that out but cant seem to pin point the problem.

    Sorry again for the essay :P

    Thanks michael
