Come on, you guys got to hear it too. Why the hell does my CTT sound like a diesel truck when you take off? Not the clanging sound of a diesel but that high volume surge type sound when you really hit the gas kind of "grrrrrrrrr" sound instead of the roar type sound you get with other V8's.

First V8 I've ever had that sounded like this and hope I'm not crazy or something is wrong with my CTT. Always remember the first time I started one up and thought "WTF is wrong with this thing????"

You sure you got a turbo under the hood???

Mine sounds like an extremely high-performance twin turbo V8. It sure as hell doesn't sound like a diesel truck. You should get yours looked at and make sure that there is nothing amiss.

My diesel does not even sound like a diesel.

Agree with other posts, something is amiss in your car... exhaust pipe leak, maybe exhaust manifold leak at cylinder head, possible turbo failure (does the boost gauge work normally?), maybe even some kind of vacuum leak, something wrong with catalyst or muffler (baffle(s) loose inside causing unusual and possibly partially blocked "flow" through), a previous owner installed a K&N or other "performance" air filter that produces more/different intake noise... quite a few possibilities. A good start would be to determine if sound is odd from underhood or from tail pipes or both.

Everyone can take video on their phones these days. Take one and post it, we can tell you if it is typical or not.

My wife called me the other day and said it sounded like my car was having problems as it didn't sound right.

I told her to stab the gas and it all goes away. There's a lot going on under the hood. It's not going to sound like a NA V8. Not at all. Turbo's turning and you may hear a little bearing sound. If you have PDCC, then add another sound to the mix. When you hit the gas, the whoosh sounds is the air pushing through the turbos. It's a muffled sound and it's normal.

If you ever think your car is sounding abnormal get it checked out rather than wondering wtf.

I'll post a video when I'm done traveling but I'm really surprised people have never noticed. Every one I've been in are incredibly loud with fans and not a sexy sound when inside the car.

Mine sounds like a great running twin turbo v8.

Are you talking about the whine of the air pumps on cold start or the spool of the turbos under boost?

It is entirely possible you have an issue like a whining power steering pump or something of that nature. Record the sound with your phone and we can tell you if it sounds good or not.

I agree, it's not a sexy sounding car until you stab the gas. However, my other car is a V8 audi and a flat 6, so this is the least sexy sounding car I have.

An aftermarket exhaust can change that. On my CTT I have a Fabspeed exhaust the barks when you start it up and sounds so nice when mashing on the throttle. My CTT sounds as mean and angry as it's performance figures state it is - love it!

Been giving that some thought.


Here is mine from the engine bay but inside the car all you here is that loud fan at startup and a car that sounds like a large hoover more than a 500hp beast.

Sounds like injector noise and the PDCC pump. It's not a sexy noise for sure, but once you step on it the sound gets going.

I have to say.. When my 928 turns on and is even just idling - it gives me a great tingly feeling.

When the CTTS turns on, it sounds very similar to uphoto's video. I've parked it next to a Kia Sorento of the same year, and that upstaged it with a more impressive engine/exhaust note. Driving it around the city.. Most of the time, I'll turn up the music to drown out the drone... Even when the engine is revving it doesn't really have any excitement to it. There's no theatrical 'woosh' from the turbos or crackles or burbles from the exhaust... Its just the annoying clattering from the engine and droning from the exhaust.
