Th400 HP/TQ loss???
Th400 HP/TQ loss??? I dynoed my car the other day and was a little dissapointed, put down 384rwhp/356rwt but the TQ seems to drop off a lot on the big end, down to 300??? I know that TQ drops off up top but is that a "normal " loss? Also what's the average HP loss through the th400 compared to an m6 or 4l60?
haven't been yet, I am waiting til I get a rear end. I never took my old set-up to the dyno but it went 11.91 with cam and 4K stall, stock motor and trans. I was just wondering how much HP/TQ people were losing on average through the Th400.
This is something I was wondering for myself as well. But to be honest I am at the point now where I could care less what kind of numbers I make on the dyno, as long as it is tuned properly and puts down the MPH I want (143mph). I will be a happy person.
if the converter is correct youell prolly gain at the track. a th400 will prolly dyno better than an unlocked 4l60. i lost 30rwhp going from a m6 to th400 /stall. 335hp with m6 to 306hp w/th400.also, fwiw, i ran 11.9@113 with that 306rwhp in a 3500+lb car,stock internals.

Confuzed-That's an awesome time for the power and weight, what size stall were you running?
