    OP, 1200 at the crank or wheel? I ask because you wrote hp not whp, and most discussions in the supra community reference whp.

    Any dyno graphs of a 7275 making 1200 whp? I don't think it'll do it, but if it will, it would be leaning on it hard and likely running it way off the compressor map. A 7675 is a more appropriate 1200 whp turbo.

    Government cannot give anything to anybody that it doesn't first take from somebody else. Whenever somebody receives something without working for it, somebody else has to work for it without receiving. The worst thing that can happen to a nation is for half of the people to get the idea they don't have to work because somebody else will work for them, and the other half to get the idea that it does no good to work because they don't get to enjoy the fruits of their labor.

    Oh yeah - i keep forgetting about those test results. Have you talked to Mark Conte about that test? We discussed it in another thtead, recently in fact. My commemts above were based on his advice - yes, the 7275 might be able to make that number, but it's definitely not happy doing it. He said he would not recommend it as a "1200 whp" turbo, and that he recommended the 76 instead. See if you can find any others.


    OP, by my calculation 800 kw at the wheel is approximately 1050-1100 whp, so the 7275 will likely do it, it'll just be working hard and service life might reflect that. The 7675 will hit that number without being pushed so hard, and might live longer because of it.

    As i was (again). Facepalm. It was Geo at Real Street, not Mark (but i did reference Mark's comments from another thread). Here's the thread (page 1 and 2, and post #46):

    This is what you need to take into account. Yes the 7275 made 1200whp but they were ringing that turbo out to its max capability. I’d choose the 7675. It’ll make your 1200hp (1050-1100whp) without spinning it to within an inch of its life every time.

    Exactly. And unlike me, Patrick IS a professional.
