Listened to the 03' engine @ Muncie

Well Listened to the 03' engine in the 2nd Gen truck @ Muncie, and gotta say as eloquently as I can... ... . YUCK

Not sure if it was the complete 03' engine or just the head and fuel system. It sounded like a gasser with a sticky lifter.

me too...

Me too... it is way way too quiet !!

I don't know....

There are times when I would like a quieter engine. I am not sure that would be all the time though.

Give it some fuel, turbo and aftermarket exhaust and I'll bet it will make some noise.

Ya, that engine was too quiet.

I spoke to the Cummins rep and this is what he told me they did to reduce the noise.

1) extended the block skiting down and added a bottom plate to keep them from rattlin.

2) The Biggie - They got the injectors to fire off 3 slugs of fuel on every firing. First shot is about 10% of the fuel for a small pre-ignition, second is the big one with about 80% fuel and the last one is about 10% for the after burner to burn off the fuel. That got rid of just about all of the knock.

The noisiest thing on that truck was the air pump which he said is not being installed on production models. Sitting in the cab, it sounded like a low trian rumble that's about a mile away.

BUT, he also said that...

It probably won't take too long for the computer guys to get rid of the pre and post injections and that should bring back the mighty sound the Cummins is known for... .

So there might be life after death after all. Oo. Oo. Oo.

One positive about a quiet cummins is the fact that twins will absolutley sound awesome.

When I went to the truck plant tour in Fenton they had one of the pilot models there and I kinda liked the sound. I would sound pretty good with a 5" straight pipe

i was there too, and WOW the factory exhaust was huge!



that one thing nice (the only thing)

I hope it doesn't sound as quiet as a Duramax. Those things are pathetic!
