I park in the oversized parking at my office. A truck in front of me started up the other day. It sounded like a jet plane. I have never heard a diesel sound like that.

I have a stock 2008 6.7l, but I was wondering if the jet engine sound was the intake. Does anyone have any idea?

Thanks,
Jay

I have a buddy with a straight piped D-Max and it sounds like a jet, just a whooosh sound at idle, I believe its the variable vane turbo on them cause the older D-Maxs didn't have that sound.

it most likely was a 5.9 with CAI, straight piped with no silencer ring.
thats how my truck sounds like.

It was more than likely a ford. From what I understand the sound comes from the vgt turbo and the flap that closes ( technical name is not coming to me) during warm-up. It is more noticeable when they are straight piped. I think it sounds preety cool.

You right pods. I bet it was a FORD. On that Garrett turbo if you have a straight exhaust and put a different compressor wheel it literally sounds like an A-10 warthog. Even with stock turbo and a straight exhaust it hisses.

My buddy has a 04 Dura crap that sounds exactly like that.

A 6.7 screams like a jet plane when you start it up with the engine brake on and a DPF delete when the motors cold. My truck screams and I get tons of head turns at the traffic lights when my trucks not up to operating temp yet. The jet plane noise stops when the trucks warmed up. There are a couple videos on the 6.7L Performance Parts Discussion of the 6.7 warming up with the engine brake on.

Heres a video I found on you tube. He turns the engine brake on 40 seconds into the video. Its even louder if you have a 5" TBE straight piped.

The 6.0 fords compressor turbines are pretty agressive. Here is an example. The 6.7 doesnt even compare. Oh, Cold weather warmups dont count!

Ummmmm if you read the order of the post he never said what kind of diesel truck he heard till AFTER my post. I was just making a simple post and suggestion. He posted after mine what truck it was. Sorry I am not physic. You don't have keep doing your ego trip in every post you make.

A truck? You couldn't tell if it was ford, chevy, or dodge? you can tell between any of them from any angle... maybe a bit more details?
