I was just curious, at what power levels does the tranny need to be upgradeed or totally changed out?

Not really sure. But I do know that the only Hennessey package that requires a transmission upgrade is the 810hp twin turbo package. They offer some 600+hp packages that dont require it.

The trans is the 6r80. Which means it has 6 gears plus reverse and should stand up to 800 hp

I thought the '80 referred to being able to withstand 800lb-ft of torque?

yea they said the same thing with the 4R100... but I have seen them ripped out before with a 7.3L making less than 800 ft/lb of TQ

And Lightnings destroy 4R100s at about 700ft/lb of tq. When they rate a transmissions it based on the max torque multiplication in the trans not at the wheels in direct drive.

yep thats what I thought it was, the rating after the torque multiplication of the converter. So in the case of the lightnings at 400 hp 500 tq they were perfectly fine, but beyond that they were hit and miss since it was pushing the limits.
