    Thought you may be interested in seeing a recent twin turbo conversion by from the land downunder on an F355.

    The engine is internally stock and at a very early stage of development (just completed - running out of injector - 7psi boost max) it's making a genuine 450 rear wheel horsepower.

    I've attached a couple images for a look see.

    Nice work. What kind of turbo's? Any dyno sheet to post, I would like to see curves, especially torque curve. Great idea, must be a blast to drive. Is it hard to get or maintain traction? Please keep the progress posted. John

    Please refer to my other thread containing the same plus extra images.

    We have literally only just got the car up and running today and the owner is absolutely rapt.

    Actually, he can't seem to stop himself from smoking the P Zeros all the way through first and 2nd gears. So yes, traction is a problem is you want it to be!

    Turbos are Garrett and once I have a print out for you, I will load them up.

    For your interest, the turbos are coming in at 2400rpm and the swell is enormous - and flat!
