GM Vortec Pull Hard

[FIC]

Its not how much power you can pull but how much can your brakes stop, tow ratings are based on stopping capacity.

I have a 2001 Yukon with a 5.3 and I am experiencing the same towing probs considering just upgrading to the XL and finding one with 8.1 but waht is the mileage like in one?

About 10 around town and 12-13 on the highway. It sucks, no question. My Sierra gets about 14-15 around town, at like 17 on the highway.

But I will tell you, I had the previous gen 5.7 and the previous 7.4, and that 8.1 is amazing. It tows my 30ft travel trailer with ease also. And I live in the mountains, nothing but hills.

If you have to commute in the yukon, I would try the 6.0, and maybe do some bolt ons. We don't drive much. We run the kids around in town, less than most. And do grocery shopping in Chico, about 25 mins away, once a week. So usually 2 trips to chico a week. Other than that, we work at home, the lake is 9 miles away. All our camping spots are close. We basically moved to where we recreate. So the mileage doesn't hurt us as much.

my 98' z 71 with 150,000 miles with a 5.7 in it will yank my 22v with no problem. it wont pull like my cummins but i havent had any problems.

I had a 97 yukon with updated intake, exhaust and chip. It pulled my 22 foot boat fine, similar to how my 2002 sierra pulled the same 22. But the 24Ve puts it over the edge unless flat.

Thanks for the info Hopefully the bolt ons will be enough

It def made a big difference. Even my wife noticed it. And for under a grand, 700 without the Big G, how can you go wrong? Smog legal no less.

There is one thing bad about having a brand new truck, they arent making stuff for the 2008s yet

Can't wait to see how my Hemi Grand Cherokee will pull the new 24Ve. After researching the Jeep boards, I am confident it will pull it fairly easily. Stopping it on the other hand.......

Also, just to clarify that true dual exhaust will NEVER hurt performance on a large displacement motor from a HP standpoint if tuned correctly. Especially with the upgraded air intake (more air in, more air out). It is true that you may lose some peak TQ however, which in this case is crucial.

[ragboy]

Right, I said degrade in performance I believe, not HP.

it always makes me laugh at everyone with 4x4's complaining about not having enough pulling power, we use a volvo V70R not the best at towing but it does the job, and we have to start from a standstill on steep hills. this volvo is like a tank haha

um... theres a BIIIG difference in weight between a 20i and a 24v: 3268 vs. 4320lbs, difference of 1052lbs. When you factor in fuel capacity, increased trailer weight, and extra equipment, you're approaching a 2000-lb difference. Thats an approximate weight increase of 61%.

For reference, the 2007 Volvo V70r has a towing capacity of 3300lbs.

That said, by simply adding your trailers weight, you're already well over the tow limit. Lets not forget to mention fuel and everything else that you'll carry in the boat or in the car.

So yeah, it might PULL the trailer but did you ever wonder why both the 5-cylinder and 6-cylinder have the same TOW rating? This is because its rated on stopping power too.

You're playing a very dangerous game.
