Ken I want your advice so I'm going to make sure I understand.
Your saying do not waste money on MAF,Throttle body spacer,and 160 degree stat. Did I understand correctly?
Thank You So Much for Your Input!!
Please write back if You have any other ideas and to confirm my understanding.
If you would like PM me on this.

Hi before stepping way out try these mods. Not like SC but if You are like me I needed a little more power and low end aceleration and got it. Plus about 1.5 MPG.
1)Cold air intake
2)Helix power tower throttle body spacer
3)ProFlash programer - it offers perf. mode, rv/tow mode., stock, and economy mode. I've tried all except economy which i will do soon, the programmer said it is not worth using that mode unless you are taking a long trip and then it will be a big help. I'm running perf. mode and it runs quicker. All these except stock do away with torque management control problem. I do not have all those weird done shifts and up shifts.
4)True duel exhaust. cut pipe at cats eliminating the x pipe and go with ?
(my choice was 2-40 series flowmasters with 3" all the way out from cats, except when I got to axle I had to drop to 2 1/2" to get over axle with 2 pipes. Which made Flowmaster tech happy.
5)I have ordered headers that will be jet hot covered to hold done engine compartment heat.
6)I'm checking into Granetelli MAF.
7)Bypass coolant to throttle body. Any good suggestions on doing this without buying all the kits You see?
8)Checking into 160 degree thermostat. Does H2 need this. It helped my truck but 2 totally different rigs. Need advice as to who i should get this from?
9)If Your a drive it a little guy like I do as I have a different every day driver and building it to compete in shows as I am (I know BO BO) If I want to go offroad I have good friends to let Me ride with them and I'm speaking of the people on this forum I'm sure would let me tag along on an outing. What every melts a guys butter it is your hard earned money. I'm looking at electric cooling fans. Do not use if offroading as I have been warned already on this site. Also let Me know what brand and model # I should use. I have used flex-a-lite in the past. I think KenP may answer this one.
You will be absolutely surprised how the beast will run!!!
Do the first 4 items first as they are the quickest to do.
I'm acually having problems with getting MAF as 05 models software is all new and they do not have a MAF to work yet. If you know different let me know. This was the same problem with programer. It just came out this month. I do not think Hypertech even has a programer ready yet for 05 H2.
All this is stuff that I did to My 99 Silverado with 5.3L If I took all the crap out of the bed and tool box no telling what it would do. It is a 2 wheel drive and I have the biggest tires I can get for it and i can smoke the tires for as far as I feel like it. It has HP's.
Hey if anyone sees anything I may want to try different please let Me know. I have a plan but it is flexible. Please You veteran's and guru's step up and fine tune my plan before I get our new member off in the wroung direction if you feel there is something new I do not know about, if you feel that may be happening
PLEASE HELP!!!! make sure We go in the right direction.
Thanks Very Much

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> GM has been using this method of reducing drive train and transmission problems for several years now on their vehicles. Most other vehicles it happens right at the shift point but on the H2 it also occurs right when you need the torque the most.

I am a new searcher to buy a supercharger, do you mean here that we need to eliminate the T/M ?? or no ?

H2 Bill,

I live outside US and my dealer told me i will be the first one who will install a supercharger. Wow, means he doesn't have experience!!

He has a Whipple SC in the stock and he can order a Magna SC if i want.

first i still confused which one i want, Whipple or Magna. I prefer the one with less problems and less visiting to the dealer everytime as he doesn't have experience with SC.

Maybe i will chose the magna as a it is a full kit like i saw in this forum...! your advise will be very appreciated.

Second: As i will be the first one who will install, so i will be the tester person for the dealer, i am afraid if he knows all the tips and tricks that needs with the SC, would you please tell me what i have to tell him and what i need to do or to buy additionally to the SC?
do we need to Better replace or rebuild everything else w/ heavy duty parts. Especially the trans. as KenP said?

Where i live, we have a lot of mountains and high speed road too and i do off-road.
I heard about the torque converter, do we need it also?


Thanks for your help

Regards
Elie

It is way cheaper and not really complicated. Intake took 30 min., throttle body at same time took 15 min., programer took 10 min., and exhaust took 1.5 hours. Header pro tells me about 2 to 3 hours. It is all he does is specialize in header application and install. Alot of the other I'll do myself. If You put it all together I guess a good 8 hours on it all. You let the pro do the work just tell him what you want. It will take a couple of months maybe not (could be by end of Dec.) to finish and then I'll get it dinoed. Nothing is as good as SC but I'm estimating less than 2 grand and pro's here are estimatimg going from 325 HP to 425 or 450 HP and they are leaning heavily towards the 450hp and a vast torque improvement, no up and down shifting anymore. These are estimates based on manufacturer HP gain and we shaved it down by rounding down numbers from factory. I feel confident I will get it in around 2 grand. Dino only rely knows hp and torque. In the first 4 items I have spent $960 and it made it feel like I was driving a different H2. Friends who had been in it before could not believe how it put them back in the seat. Out of the remaining the real help will come from the headers.

I really would like some input on the MAF, coolant throttle body bypass, and the 160 degree thermo.

I know electric fans will help as I noticed a big difference on My silverado when I put it on this past summer.

Guys jump in here and help me with the questions I have on MAF, Throttle body bypass and 160 stat. I know someone has had experience with those things.
Thanks
Rick

Rick,

Wow, it seems a rich solution but i think what you are doing is more complicated and less cheaper than a supercharger?

My target is: I want more speed and more torque power, because i like speed and also i like to by-pass the X5 and the Cayenne.

[H2 Bill]

H2 Passion, yes you want to eliminate it, and this is done through re-programming the PCM. If you don't and you install a supercharger it will not perform well at all. Most of the manufacturers include this reprogramming in their package, some at extra cost.

[MAC]

Do they offer supercharged Hummer for test drive? $5K is a lot of money. If we can test drive a supercharged Hummer, I think we can pretty sure to tell if it is a fraud or for real or just maybe. I climb steep hill everyday and my Hummer is full of power, if I can test drive a supercharged Hummer, it won't go any faster (twisty roads) but maybe I can feel the surge of power that pin me to the seat, that would be good enough. I wonder if any Hummer dealer has one for testing?

[TheGoodHummerMan]

Patriot,

Thanks... I've researched superchargers a little and read about theory and how they work, different "types" etc. It sounds like the roots type (Eaton) is a good choice because it is effective at lower rpm ranges than some other types. I now understand what an intercooler (or aftercooler) does... but one thing I'm not sure about is what "more power under the curve" actually means.

Anyone have any ideas?

Also, if a supercharger requires using premium fuel instead of regular that's about a 13% increase just in fuel costs (or roughly about $200 more per year).

Rambling on like a mad man...

I figured you didn't really mean it like that Ed, Just pickin on ya I love muscle cars, and would love to own one, but I like new cars as well, so the Z gives me the best of both worlds!! But I would still love to own a red Judge, Orange Charger R/T, or a 70 black Chevelle with two white stripes, 454, and my own personal 1 million gallon gas supply

Bill,

Perfect! That was what I needed, a simplified explanation!!!

It sounds to me like the H2 can really benefit from re-programming the computer AND having the added horsepower and torque to "play" with?

I don't care at all about making my H2 quicker in the quarter-mile, but having the added power for towing or even for normal driving in hilly/mountainous areas sounds more and more tempting.

Thanks a lot for the info!

[whipplecharged]

Ed,

When you take off from a dead stop and the vehicle doesn't take off right away that is the T/M and when it shifts and the vehicle does the same thing that is also T/M. The stock programming takes out 15-22 deg og timing neg. That GM's way of trying to save drivetrains. Instead it is a pain.

On superchargers, most have been set up for stock motors. Like the Whipple they run about 5 1/2lbs of boost to bring the HP from 316 stock toto about 435. You do have to run prem fuel but it does burn better and keeps eveything cleaner. This making the vehicle perform better and helping with increasing your fuel milage, even if not supercharged. When you use a twin screw supercharger like the Whipple you are going to get the power down low and you will use less throttle to do the same job you are doing now. This helping you increase your fuel milage and also getting the T/M out will help you to.

[H2 Bill]

Actually torque management is fairly simple. It is part of the computer program that "reads" how much torque your engine is producing and once it gets to the programs' max torque setting it backs off or retards your ignition thereby reducing the strain on your drive train. GM has been using this method of reducing drive train and transmission problems for several years now on their vehicles. Most other vehicles it happens right at the shift point but on the H2 it also occurs right when you need the torque the most. When you install the supercharger and don't eliminate the T/M it actually "magnifies" the problem.
This is certainly a simplified explanation but I hope that it helps you get the idea!

What does "below the curve" mean, anyways?[/quote]

Horsepower and torque are usually draw in a curve configuration relative to RPM's.

Power "under the curve" as I understand it means that the curve is drawn higher up on the chart therefore said engine has more power "below" that curve line. If the line was drawn lower along the coordinate axis, there would be "less power under that curve".

Someone jump in here if they can make it simplier.

As for the SC question of too much strain on a stock 6.0? The stock engine isn't "engineered" for a SC. Therefore, with hard driving the system will fail sooner than without a SC. However, 5-6 psi of boost with the Magnacharger, Whipple or the Kenne Bell (which by the way looks like the best set up in some respects) is not much as my stock Volvo 740 Turbo ran 14 psi with a little tinkering (it was only 5 psi from the factory).

You probably can blow darn near 5 psi from your mouth into a stout ballon before it begins to expand. No need for extra valve springs unless you like to see 6000 rpms alot.

Just my two cents.

[whipplecharged]

The radix supercharger by Magnacharger is a good kit and is intercooled.I have had customers run it on the dyno and have made good hp and they also run the Whipple on the dyno and made 36 more hp than the Magnacharger.

Overall the Mgnacharger is a good kit and everyone That I have talked to with one is happy with it.

But if your after an intercooler supercharger it is a good way to go. Whipple is also making an intercooler upgrade that you will be able to add to existing kit. It's supposed to be ready sometime this summer.

[h2fan]

would that extra hp from the whipple come from some one who knew how to programe that unit better then the magnacharger i wanted the whipple but my tuner said he would rather go with the eaton/magnacharger with the intercooler so kinda of shopping for price seen them for around 5k

[h2fan]

got a price installed for 6800.00 with there own programing. for the polished unit with new valve springs and 3/36 warrenty i know the installers will do it right. they have one of the best programers in the country. i have a z06 that they worked on

[h2fan]

4900.00 for the mag
