    Trans for turbo's

    Going twin turbo soon, just wondering what transmissions/clutch you guys are running and how you like it. Looking at the 700hp range.

    MMR TKO 900... 4.10s.

    I love it. I have a turbo and 700+ rwhp.
    The TKO is fun though too.

    What are you going to be doing with the car?

    t-56 but I think an auto would be a blast allowing the car to stay in boost the whole run

    If it's mostly a track car, I'd say the TH400. If you drive it on the street (like the 7 hr trips you mentioned) then a 4R70W is the way to go.

    I'm running a 4R70W built by a local shop and it's awesome. With a 28" tire and 3.55 gears, I can cruise at 70MPH on the highway just under 2k RPMs (I was running a 26" tire with 3.31 gear before I made the switch).

    If you decide to go with the 4R70W, check your valve body carefully. I've seen both PA and Lentech valvebodies come bad right out of the box.

    T56 26 spline with Ford Shelby GT500 twin clutch. Love it on the street. Also recommend the 4r70w with the Baumannator.

    If he doesn't plan on making more than 800ish rwhp, then yes, a 4R70W would be a better choice b/c of the O/D.

    Built right, a 4R70W can handle more, but again, it's gotta be built right.

    This shop has several cars running 8's and 9's on full weight turbo cars with a 4R.

    That being said, I would still take a TH400 for an all out drag car......

    Lentech claims to have one good to 1500 HP.

    I've personally don't know anyone making that much that is using one, but I've personally made 780 thru mine, no issues.....

    I agree with you but I've personally seen too many fail when they were "built right". I've never personally built one so I do not have first hand experience with one. I'd rather take my chances on a 110% tried and true TH400 and slap and Gear Vendors O/D on it or do a 4L80E swap. Parts for the TH400 are everywhere and they are cheap. Just my opinion though.

    i've got a 4r75w out of an 05 f150 with a pi triple disc converter and from the research i've seen that trans should hold anything a street car can throw at it, i'm ordering the freddie brown valve body on the fence about a trans brake or not, but i think for an easier install an aod trans with manual vb is the way to go imo.

    I've gone back and forth over this but i think I've im going with the magnum. This is mostly because i just cruise around and don't really go to the strip and i like rowing the gears. Ill probably change my mind a couple more time but what are you going to do.

    On the street the spec 3+ is good, but not at the track. I smoked 2 of them at the track. Put a TH400 in the car now.

    I am in the process of putting in a TH400 with a gear vendors overdrive before I wreck my T56.
