This is not my Bronco, mine is two behind him. It is a 4BT with compounds and a built 47RE. This was his first trip on the auto & the torque converter was not optimized at this point. I think he was only running 40psi at this time too, now he is around 70psi. :)

@caddycoupe1021 That's what a 4bt sounds like

@madmaro00 got to admit i liked this. i wonder if the guy immediately behid it. , on his knees adjusting something wonder if he knew that soemthign was about to happen?

they probably still have the turbo silencers in

@1thumes actually most twin turbos i've seen are quieter than a single turbo

@seifs4 I know what the 4bt is im putting one in my dakota, it doesnt matter if its a 4 cyl civic motor when something has twin turbo theres usually a serious whistle while actually making the motor quieter, in this video u cant even hear a slight whistle and if he was making 40psi of boost he should be making at least 200 hp and probably twice that in torque

@1thumes well its only a 4BT cummins, which is basically a 4 cyl version of the 5.9 cummins. So they dont exactly have lots of hp but they still have alot of torque.
