Boost can make anything put out power. Those numbers sound right to me.

Sounds like he is full of ****. That 5 speed (T-5) would explode under 400whp.


Ask me how I know.

There have been 305's in the 9's, so I wouldn't judge them all based on one video. Numbers he's claiming are believable.

I have had stock T5s dies behind a stock 350 with a 100 shot and live behind a 500+ HP 383. They are hit and miss.
