Im taking delivery of a 2006 GMC Sierra crew on friday w/ 16,000 miles and a 4.8. I cant decide on a supercharger kit. Im trading a '05 sierra sc/sb that had a 5.3 with 70,000 miles and lots of bolt ons, and wanted to make up the gap between the two and then some. Just lookin for some insight from owners of both systems. Plan on towing a rock crawler a few time a year and smokin some hemi's and stangs. Thanks

 

Radix for towing

 

I agree with the roots style blower for towing applications.
Performance/Racing apps i would go with the procharger.

Have you looked into turbo kits, thats the best of both worlds.
Check out Trick Performance . That would be the cheapest and best route IMO.

 

For towing either would work great, but with your cubes so small in such a big truck, I'd go with a Radix. That will allow you to be quick with the stock torque converter. The Radix is also sized well on 4.8L's.

 

Ok, so say i go with the radix, is it worth another grand for the intercooler setup? The procharger comes with it, i can have it to my door complete with intercooler for 4250

 

Well worth the intercooler. Does the Procharger for 4250 come with:

Injectors
Tune
Belt
I/C pump
All needed plumbing
Fuel Pump
E.O.#
Tensioner
Detailed Instructions
3/36 warranty on parts


etc, etc?

 

where can you get a I/C set up for that cheap, or is it used?

 

Stage 6 performance in jacksonville, fl; thats new with the pully setup, supercharger, and they us a secondary fuel pump to bump up the fuel pressure. Is all the extra, ie; injectores and tuner needed?

 

Whats the best going deal on the satin radix intercooled verion, and were at?

 

mine only came w/ one set of injectors
