All Show and No Tow

  

JakesSUT -> All Show and No Tow (7/11/2007 1:57:14 PM)

Hello Everyone!

I have a stock black and chrome 2005 H2 SUT.  I had a custom black and chrome 24 ft. enclosed trailer (5,000 lbs.) made to match the H2.  I use the H2 and trailer for my business.  However, the H2 does not tow the trailer very well.  With even the slightest incline or small hill, the H2 "kicks down" and revs the rpms fast and hard.  I am concerned about blowing up the drivetrain! 

I can not afford $4,000 - $7,000 for a new supercharger kit right now.  Does anyone know of any towing techniques or used supercharger kits???????

How much wieght is the trailor filled with what you are towing? Have you ever put it on a scale to see if that is the actual trailor wieght? If you are pulling a large load up an incline, it's normal for the transmission to downshift, but if it's a small hill, it seems to me you might be towing more wieght then you thought.

Thanks for your input.  I have tried a chip in my Ford F150.  No real power gains, so I went to a  Magnacharger supercharger kit.  As to weight of the trailer, I am only going by what the trailer shop said.  I have an all aluminum frame, therefore it is suppose to be as light as possible.  I have not tried to pull it loaded yet.  Thanks for your comments.

What modifications do you have done to your hummer? Do you have alot of extra weight(sound system and more chrome)? Supposedably a hummer can trailer a lot of weight.

the H2 is only rated to tow around 7500 lbs, and that's most likely based on a flat surface.  i tow a 26' camper, and if i'm ever in overdrive, i must be going down hill.  are you utilizing the tow/haul mode, or just towing in standard mode?  either way, you've got a dinky 6.0 liter engine hauling a 6500 lb brick, with a 5000 lb brick connected to the back of it.  it's not going to break any speed records.  i prefer the downshift going up hills, it keeps the rpms up and allows the coolant to circulate a bit faster, since the H2 stock cooling system is such a POS.  you could look into re-gearing it if you're going to be towing consistently, and that's your primary use for the H2.  but, if you want something that will tow without knowing it's got a brick behind it, you'd be better off with a diesel, either a ford excursion (may lightning strike me dead for recommending a ford) or a dodge pick-em-up truck.  the H2 may be many things, but a tow-beast it is not.

Nutin wrong with recomending a Ford[:)]

shortbus -> RE: All Show and No Tow (7/30/2007 7:50:18 PM)

i actually owned one, a retired CHP mustang.  it was a lot of fun, but it still feels wrong to go that route. . . .[>:]

Before I ordered the custom cargo trailer (built on a Continental cargo auto hauler aluminum frame) I asked what kind of tow vehicle to get.  All the trailer shops recommended a Dodge turbo diesel as the best tow vehicle.  However, industry experts (casino gaming) all recommended a "show and go" vehicle, with the top choice being the H2.  The H2 and matching trailer is impressive.  However, after its loaded,  I am going to have a very hard time driving up hill. 

Now, I am looking for a Magnuson supercharger Radix kit.  I was the high bid on a never installed kit, on ebaymotors recently, but someone with "bidders software" outbid me with only 6 seconds remaining in the auction.  If I can not find a used kit soon, I will just have to buy a new kit from the forum sponsor, G-Style Hummer Accessories.  They appear to have the lowest price.  Thanks for everyones comments.

Jake, did you get the kit yet?

JakesSUT -> RE: All Show and No Tow (8/15/2007 1:00:37 AM)

Yes!  I just won the exact kit I needed on Ebay Motors.  The same auto dealer that had the auction for the kit that I lost, had another auction for another kit the following week.  It is the Magnacharger Radix Eaton M112 Intercooled kit.  It is suppose to be  new, and never installed.  Its missing the ECU programmer and the intercooler reservoir.  I called Magnacharger and they will sell me both items for a very inexpensive price. 

This will be my second Magnacharger kit and my third Eaton blower.  In my experience, they are the best for towing and the Eaton blowers are very reliable.  I will install the kit myself.  I will provide updates after I install it.  Wish me luck....I will need it![8D]

Good luck with the install of the magnacharger.

JakesSUT -> RE: All Show and No Tow (8/31/2007 4:40:14 PM)

Remaining parts arrived and I installed the kit several days ago. I still need to try it with the trailer.  I will update when I do.  Without the trailer, the H2 would kick down on hills.  Now it does not kick down at all.  Much more power.  The Hummer feels "nimble" and more responsive.  Its amazing how much more faster off the line that it is.  Note the following:

Removing hood and lowering front tire pressure provided better engine bay access.  Removing 6.0 vortech plastic intake manifold is suprisingly easy.  Even though gas tank is plastic, its heavy and cumbersome even though fuel light was on-better to have 2 people remove it.  Should use 2 people to lower supercharger/intake assembly on heads.  For H2, kit manual nor online instructions did not apply when downloading supercharger program from Superchips Micro Tuner to H2.  Magnacharger actually told me to use a PAPERCLIP to "jump" terminal b to d in a specific plug-in under the driver side dash....yeah, a paperclip! haha!  However, it worked and downloaded the program immediately and I did not need to remove fuses as manual stated.  You will need a  METAl holesaw drill bit to cut through the grill bracket to mount the heat exchanger and I had to drill it at an angle and it still worked.  Read instructions carefully as there are different proceedures for 2003 and 2004-2007 models.   Found it odd that my 2005 H2 Sut does not have an inline fuel filter (its in the gas tank).  In comparison to my F150 supercharger install, the H2 was easier.  Very well made kit.
