An Engine That Sounds Like a Yeti.

I work for a camp with multiple vehicles that take children into the back-country for back-packing trips. Among the vehicles is one lovingly referred to as "Lil' Boy", a 2003 Excursion with the 6.8 V10. It also has upgraded exhaust so it is a bit more meaty sounding than normal.

About 30 miles into the back-country, a moderate size pot-hole (typical for the grooved-out half gravel/half paved road) knocked the vehicle pretty well. All of a sudden, I heard the very loud revving of an engine. I was following a Suburban and it slowed very quickly so I figured it had downshifted and I was close enough to hear it, but I immediately realized it was from my own vehicle.

On the side of the road, I looked underneath Lil' Boy to see a broken welding point after the exhaust manifold. We were about 10 miles still from the trail head, so we marched on, with an un-muffled engine note. It was rather obnoxious, but it certainly fit the personality of the beastly Excursion.

Upon the return trip (13 miles of 7-10% downgrades and switchbacks) I discovered that the scream of a Yeti is actually the exact same noise produced by an un-muffled 6.8 V10.

Jeez, That must be loud.

Our summer camp had a mini-fleet of donated beater cars. Their names, I believe, were Pig, Squirrel, Polar Bear, Groundhog, Turtle and Minnow.

Those V10s make a lot more bark than they do bite. Loud, raspy and really not all that powerful.

Yeah, I was amazed what it takes to get more power out of these engines. Lots of money for little gains. Although the 3V is a whole lot more impressive than the 2V.

from 99-02 truck stock is 275 hp 410 tq 20 valves, from 02-05 its 310 hp 425 tq 20 valves and 05 and up have 357 hp 462 tq 30 valves. Not sure why you think 310 hp isn't that powerful, even though it's really about the torque on the V10. I have an '03 F250 with the V10 and it will smoke the tires and haul 10k lbs all day long without flinching. It's also quiet as a church mouse with stock exhaust.

That is for certain.

That sounds like a great fleet! We've got Chile Pepper, Bourbon, Crystal, the Black Pearl, Lil Boy, Dumpy, and New Truck. Crystal is our boss' Lexus that was stolen by some Meth-heads.
