yeah that sounds wierd. It just must be the drivers driving style....my stepmom gets about 13-14 with her 6.2 denali and my mom get 14-15 with her 6.0. But when I drive it I can get 17-18 out of it...

For example my cousin has a 5.3 tahoe with LT's, Magnaflow catback and AEM Intake, my tuning and gets a solid 16-17 mpg but now his fiance drives it I think she goes for a best 60' time on every stop LOL(I rode with them today) and he said shes gettin 12-13 with it...

I dont see how the 6.0 tows better than a Dmax......

8.1s do guzzle gas pretty bad!!!
my old boss use to have one... i had the rev limiter set to 6000 or something... manual shift it at 5500 and it would guzzle gas and get up and go.... cant compare it to a Dmax though..

So you have a 6.0 truck, a 6.2 Denali, an Armada, a Supra, a Vette, a g-wagon and now you want a suburban of all things for a DD....

sounds like your drive way is a high class indian reservation JFWY

obviously mpg doesnt really matter here and you want something that you can still have fun with but can DD. I'd go get a new D-Max CCSB and put chip/intake/exhaust on it...

IDK either but it was just one persons opinion. I would take a d-max over a 6.0 any day.

The armada is the wifes,
the 6.0 truck is our company back up vehicle.
the Two denali's are my mom and dads, one a short one a XL,
The G500 is getting replaced by a suburban,
Then supra is not very daily drivable with out going to jail.
The corvette is a once every few moths toy. I ve had it 18 years and it was my was my old mans... Its now almost 14:1 compression after i had a few issues with a crank So it runs straight 110 octain and at $5:95 a gallon it hurts the pockets! it also has 4:56 gears soooo...


I think the MPG thing depends on how big your city is and where you live. If its flat you should get grate mpg. Where i live we have mountains.. The elevation in my driveway alone changes 1900 feet.


a Few years ago, TByrne had a whippled 8100 burban and i think with the whipple alone it went 13.3's. Whipples web pays says a intercooled 8.1 will make 800lbtq those are crank numbers... then Tierod on here had the 8100 truck with heads and cam.. i think he said it dynoed 390whp and 440wtq...

The only problem with D max is the local dealers void the warranty if you do anything to them. That and a few friends have them.. The D max isnt all they brag about.. at least the ones ive rod and drove.. Also if you dont do awd full boost launches in the diesels they are no quicker or faster than a gas truck... they just seem like it because they shift at 3K rpms. Sorta like a honda civic... you can row the gears in those little cars but your still not going anywhere..

I see, that makes sense now! At any rate if you really want an 8.1, your should try to find one of the quadrasteer 'burbs like this:



I personally like the styling inside and out on the 07-08's and if you get a 6.0, its a lot easier to make power. A nice set of heads, blower cam(gt2-3 or hot cam), and a maggie would probably be a solid 500+ Hp and 550 or so TQ set-up.


This is sick though, def. my style!

Kerr

That quad steering is nice but i we paid a claim on one of those in the denali truck It was $6500. guy ran off the road rear axle tube cought a huge rock at about 45 mph... it made hell of mess.. total bill was $8K so the truck its self was not hurt to bad.

Are you planning on doing that?

This will solve all your problems.

Or you could wait until they get the 4.5L Duramax in the suburbans.

However if you are choosing between a 6.0 and an 8.1, I would definately go with the 8.1 if I was going to be leaving the truck stock. Old rule of no replacement for displacement applies here. In stock form the 8.1 just tows better than the 6.0. However if you are planning to change the camshaft and do full bolt on with a tune, then I would go with the 6.0 as it has better aftermarket support than the 8.1. At the same time, if your willing to go the supercharger route on the 8.1 with a tune and full bolt-on's then you may be accomplishing the same thing.

Also, the 6.0L has the "potential" to get decent highway mileage maybe 16-17. The 8.1 gets about 9mpg in the city unloaded and 12-13 on the highway. It just drinks a lot more gas, and it may burn a little more oil due to the larger diplacement.

Personally, I'd go with the new 6.0L with 353 hp and 373 tq with the 6L90E tranny. You wont have any trouble getting heavy loads moving with the 4.03 1st gear vs. the 4L80's 2.48. Cam and bolt-on's will give you plenty of power.

I spoke with him about doing a swap a last year. He only does 00-06 body styles and the conversion is about $30K... He has one on ebay right now.. $79K.

I would wait on Gm to bring a diesel but they have been saying that sence 99. I had a 92, 94, 96 6.5 turbo in a tahoe and suburban... they arent much...

With that much of a gear ratio a change id say the 6.0 actully does as good as the 8100 then..
