I made it to CA last night (late)without any trouble. I even saw the temp gauge read 185 (I think, the second mark on the gauge, 160=cold at start then the next mark=185 followed by 210)210 is still where it trucks temp stays most of the time but at least on the down hill parts of the trip between Vegas and Ca the gauge went to 185
I'm still concerned about the temp being 210 most of the way home and even more so now with the 160 thermostat installed.
I am almost 100% certain that the cooling issue for me isn't my radiator or the trucks stock cooling components.
The problem is with Mangnacharger's inner cooler. It's not big enough or efficient enough.
How do I know this? Simple while going down a couple of the long hills with the temp resting at 185 I accelerated until the supercharger came on and the temp rose very quickly back to 210...
So I'm going to look into getting a more efficient or larger intercooler and see if I can't keep the trucks operating temp down around 185.
I know a change of 25 degrees isn't that big of a temp jump especially under acceleration. The trouble is that the supercharger comes on or kicks in at 2000rpm's which is anywhere between 60mph and 80mph depending on the terrain. This is a problem since most of the country's max allowed speed is 65mph or better. (And I can’t drive 65!) A bigger concern right now for me is what happens when summer hits in Vegas? Do I leave the truck in the garage for 16 weeks? I don't think so...

I got my truck back once again from the dealership (only 3 weeks away this time)
Taz,
I am going to assume that I am still going to have problems based on what you've said in this second paragraph.
The fans are running or operating in the correct direction, i.e. blowing air towards the block.
With the truck idling in the driveway the fans came on at just about 200-210 they ran for a bit then shut off. I let if idle a little bit longer and they repeated this function.
Unless I'm not understanding you correctly my normal operating temp now that the 160 t-stat is installed should be somewhere between 160 and 180, correct? And if that true then I still have a problem because normal seams to be just under 210 by the width of the needle.
I leave for Ca in a couple of hours so hopefully it will be an uneventful trip.
I want to tank everyone for there support and advice.
Fubar

Congrats Fubar
As best i can tell from Pics it looks like they did a good job and did it correctly. My eyes are not great but, if You would like to send Me some more detailed pics blown up more in size I will be glad to look the install over real close for you. You know how to get into touch.
Did they get the T-stat wire hooked into the harness at the H2 computer and set Your turn on and off temp?
Well i really feel Your trouble will be over now.
With My setup I have to make 6 WOT runs during tuning without rest in between, to get the rad temp to go to 200 degrees. I'm taking hard runs with no metanol or CO2 spray.
Let Me know if I can help with checking the Pics closer.
Fubar You are right on Allen. Is He not the most accomedating guy You have dealt with. He is just a great guy and I would encourage anyone to ask for help from Him. He is a small shop but, You would not know it by the amount of work He turns out. He does most everything Himself so He makes sure it is done right. He has onw helper and His wife cracks the whip I think.
Well again congrats Fubar!!!!!!!!!!! </div></BLOCKQUOTE> </div></BLOCKQUOTE>
