Towing with a supercharger

[donut slayer]

Anybody have any experience towing with a supercharger? I have a 04 Tahoe Z71 5.3 flex. I tow a travel trailer that loaded will be about 7k or less. It pulls good now, but I'm looking for more low end grunt and dont have the $$$$ for a diesel at this time. Will it have cooling issues with the SC? Can the stock 4L60E and 10 bolt handle the added stress?

We towed/tow with a supercharged vehicle all the time, no issues, so long as you know when to get in it, and when to take it easy.

I had a 2004 Z71 Tahoe, with a Radix/LTs/cam. I did upgrade the transmission cooler to a B&M, but ran the stock Magnusen intercooler. Never an issue, and towed like a champ.

Are you on stock tires? Rear gears?

you should actually have yer vehicle dynod because yer probably pushing the liimits of your stock 4l60E because i think there good up to about 350 hp and a 5.3 stock is about 320 then throw in a supercharger yer well over 400hp i think you at least need to convert it to a 4l65E
for wieght as long as you dont go much above 7000 lbs you should be fine there is notthing wrong with towing with forced induction diesels are towing machines and they are all turbocharged

My transmission held up just fine. My only upgrade, was a Vette servo.

Will help towing and great power! Just know when to mash it by rolling into the throttle while in a gear then letting up while shifting to reduce line pressure

yes im sure his would hold up just fine as well but then throwing 7000lbs of weight into the mix wich is pushing mighty close to max towing capacity
im not so sure

Towing would be the least of my worries. Throwing 12lbs of boost, would cause much more strain on the transmission. The towing rating is not just for the transmission, it is for all other components as well (ie. Brakes, steering, etc)

okay lets clear up one thing horsepower is horsepower to a transmission the tranny dosent care how the horsepower is created

Truck is stock except for a BB tune on EFI live. 4x4, 3.73 gears. I do have 35x12.5x17's on it.

You should be fine, provided your transmission is in good shape to begin with. A TransGo HDII shift kit wouldn't be a bad idea.

Keep in mind, the vehicle will still need the same amount of HP to tow the trailer, with or without boost. So essentially you will be towing in a higher gear, than you would otherwise.

We do drop all major brand superchargers, happy to get you info on any.

I've got a Whipple and will be towing a 7k lb boat around....once I fix my melted transmission. The 6L80 didn't like the extra power.

 

[JennaBear]

How much boost were you running?

If you are running Whipple's standard tune, that would make sense. They remove all TM from the transmission, which is not safe with that much power.

A supercharger is going to wear everything out years before they would otherwise, that's just the cost of it.

It wasn't the supercharger that took out the tranny, it just exposed the flaring really fast. Had full TM on doing my first WOT run and I flared. Trans was shot before I put on the Whipple.

Yikes!

I had a blower on my 04 Z71 Tahoe. It also had LTs and a cam. Great setup, never an issue!

I installed a Whipple on my 02 Denali a few weeks ago. Install was rough due to their crappy instructions but now it's on it's a blast. Next up is a cam and longtubes. Yee-haw.
