Took the LTZ in today for some warranty work. The dealer finally cut loose with a loaner.

They gave me an '06 LaCrosse with the 3800 Series III engine.

Pretty weak engine I must say compared to the 3900.

 

My Mother has a 2006 Allure (Canadian name for the LaCrosse) and it has the 3800 in it. Feels very similar to my old 2001 MC with the 3800. Both are rated at 200hp. I often wondered how the 3.9 compared. Now I know.
Thanks Grampa Dave.

 

My 03 had a 3.8L in it....
The 3.9L will blow it away......

The 3.9L has no problems keeping up with some of the smaller V-8's

We have an 07 Mustang with a 4.0L in it and the Monte walks away from it with no problems what so ever
4.0L is rated at 211 hp at the rear wheels.

 

i'm very curious to see how my car keeps up with the 3.9's and the 5.3's

because i have no problems with the 4.6l mustangs...i really want to find someone around here with an ss that will actually give me a go..most of them dont do anything..lol

 

Wiz, there are a few of us 3.9'ers here that are just as curious as you.[sm=gears.gif][sm=gears.gif]

 

You are most awesomely welcome.[sm=shades.gif]

 

Include me in this.

 

I guess IMHO it's common sense that the 3.9 would be faster....242 compared to 200.

 

Heck yeah, anyone got a stock dyno map for the s/c 3.8?

 

yah, i think the 3.8 supercharged though is 240?? so its right close to the 3.9 l hp wise...and then the mods are so easy to do to the 3.8 superchaged engine.. so it should be pretty easy to get it over 300 hp
