    What can they handle?

    I think the 4r70w can handle somewhere around 700 lbtq.

    Im talking stock internals.

    Keep in mind the marauder is a lot heavier than a mustang, so what the trans or rear end can handle in a fox isn't true in a 4000+lbs car. I've seen people with a 5spd manual behind a mostly stock 2v in a crown vic / grand marq blow the 8.8 to pieces doing dumb shit.

    Engine is good for about 450 wheel, some people go past that with meth but I would never. I'm at 440 with the manual on a very safe tune and only 8psi boost.

    I would absolutely suggest a trans cooler and a j mod for the trans (maybe not pulling out the spring) to help prolong the life.

    Yes, I'm 100% sure. I speak from experience. I blew my stock trans soon after installing my Trilogy SC (13.5psi) and I was no where near 700TQ. I now make about 640HP on a built 4R70E transmission with hardened everything. I'll see how long this one lasts.

    The 4r70w was built to handle 700 lbs ft tq.

    In 04, they upped it to 750 by putting in the 4r75w.

    Actually the 700 is divided by 2 which makes it handle 350lbft not 700
    Do some research and apologize later.
