1700 hp through a 6l90 trans

Thought to share this with the members. Always heard these trans were pretty reliable.

1700 hp though a 6l90

So as many know I have been pushing the 6l90 to see what it will hold and how fast it will go, as well as pulling it to inspect and measure for any wear. Well so far we secured the record at 8.4@153 with car shutting down a pinch short of 900 ft due to a fueling issue. 26 passes on this unit...

Yes they are!
My friend's Chevy SS is running 151mph+ trap speeds on a stock bottom end LS3, and Stock 6L90 trans.
Not saying its happy with the stock trans....but it's holding! The diff is a different story, after 2 passes it grenaded. Car is currently running 9..4 and he feels with some better traction and more tuning the car should break into the 8's. He's running a 2.7 litre Harrop blower, frankestien heads, 2" primary headers, and a donkey dick cam grind of secret spec.

do you know which heads he is running from Frankenstein???? I really like to 710 heads.... 10 degree, perfect for turbo or supercharged.

Haven't been able to play with a 90. Are they like an 80?
I've done a few of them, they cross parts with 400's, so they are pretty stout. My stuff tends to be donor pickup cannibalization...nothing cool yet.
