who's running a supercharger?

[2slo4now]

Hello to all

New to the forum. Coming out of a whipple supercharged Chevy crew cab with gibson headers and exhaust, airaid intake, hypertech supercharger programmer and a 125 hp single fogger NOS system and getting into a H2 is a humbling experience. My new h2 is weak as a popcorn fart. "no offense intended to the folks that think that the h2 has plenty of power."

I would greatly appreciate some feed back about the magna charger and the whipple. Specifically, accurate highway/city MPG and the average hwy speed you drive. "set the cruise at". Boost pressures at full throttle. whether or not you have a programmer flash program installed. Shifting issues? I know that this is a lot to ask but 0-60 mph times would be really cool.

Installation time and cost is of no issue to me.

Also, from all specs I read it seems that the Banks 4 inch mandrel bent exhaust system would be the only way to go with the extra air pumping through the charger.

Thanks in advance for ya'lls help.

Hi,

i want more acceleration, increase the torque and HP power. Many times, i am the target of many X5 BMW and Cayenne, so i want to bypass them in acceleration and high way speed.
No speed limit where i live and we have a lot of mountains. (outside US).

i can see 3 main types: Vortec, Whipple and Magma.

Vortec: Increase your horsepower from 316 to 436 and torque from 360 lb./ft. to 465 lb./ft
Vortec

Magna: 63-125% more horsepower (from 2,000 rpm to 6,000 rpm) what about the torque?
Magma


and the Whipple: Up to 50% horsepower increase
Up to 50% torque increase throughout entire RPM range. Whipple SC Whipple

Which one do you advise me to buy and why??
i want it for outside US.

Regards
Elie

We got our Whipples from ExtremeFlow and I believe their price is a little under what they quote at superchargersonline.com That MAY be because we ordered "kits" in varying "stages" for 3 H2 units (we're leaving 1 of our 4 stock as a "baseline".)

We'll be installing the intake/exhaust and doing the flash programming sometime this week or next, and then installing the SC units in about 3 weeks (?), when I return from a trip. We'll be attempting to keep detailed records and photos of our installs and will post the photos/data either here or just post a link to our own servers.

Hope this helps!

I am not after enemies either. I have a long and extensive background and knowledge with the Whipple Superchargers and have done a lot research on the other types out there.

Also one thing to remember Whipple will be coming out with their intercooler for these kits....

What is the name of your shop? Just curious.

I installed the Magnacharger on my H2. Both systems are good, but what tipped my final decision was the Magnacharger upgrades the fuel system. The kit includes larger injectors and fuel pump. I felt increasing the HP as much as these systems deliver, it was a better choice.

Not to argue with you whipplecharged but

after you made your post that the magna makes 8 lbs of boost and still makes less power than the whipple I made some calls. Straight from the mouth of the tech department of whipple the h2 system makes 5 maybe in a rare instance 5.5 lbs of boost. Straight from the mouth of magna came 5 lbs of boost and if you pull a long long grade at max power it might, just might see 6 lbs. I TOTALLY agree that the Avation screw type supercharger (whipple) makes less heat and requires less hp to spin. No question. But if the PCM has to retard timing because of detonation because of to hot an air charge then you are making less power. No one will ever know the after charger temp or the after intercooler temp but I'll bet the magna is cooler.

One last thing. Who did the dyno testing that you mentioned. I nor anyone I know has ever seen a 4 wheel drive dyno. That includes whipple and Magna

Tell you what. We can settle this once and for all. Let me get my supercharger on, swap out the exhaust and I'll take it down the drag strip. I'll post the 1/8 and 1/4 mile times and we'll go from there

My H2 is speeding up some. Installed the Magna system. It took 9 hours or so using all hand tools. "except a cordless drill" I found the instructions exceptional. The kit went on with ease and I only had to tie into 1 factory fuel pump feed wire.

The H2 has alot more power than my vortec 350 whipplecharged truck. It has no, I mean NO detonation. Shifting is perfect. I am not well impressed very easily, but I am with this Magna system.

Test and Tune is happening at our local dragstrip this Friday. I'll keep ya'll posted.

I agree, I too am still debating between the two. However I've recently been thinking of going with the Whipple because it'll be easier to get to the high HP like I wanted. If I remember correctly the Magna is actually limited to about 550-600 HP. Can anyone tell me if I'm right or not? Don't know if this matters at all 2slo4now. Anyways...

Dan from Alabama,

What part of Alabama. I live in Jackson, MS and have had experience with the local shops and am not very impressed.

What a great employer, he not only buys 3 H2's for his employees, but he also supercharges them. Apex IV, your company's fringe benefits are outstanding.

Hey whipplecharged...I was only getting 5lbs. max when I first installed my Whipple last November. I thought that my bypass was opening to soon so I called Steve and he suggested that I purchase the smaller pulley to see if that is still the max boost I could get or if it was the bypass valve. It now goes to 5 1/2 to 6lbs. max. As you can see I have headers and exhaust. It sounds like that is something that is taken in to consideration now when you purchase one for the H2. As I mentioned in a previous post overheating has never been an issue even in my extremely hot climate!

Apex IV,

The intercooler for the Whipplecharger will be out in a few months. They still need to do a ew more modes for correct fitment and calibreation of the Whipple cpu.
Also they are testing on the 2004 motors.

Here's the proof.

[whipplecharged]

OK I can answer this.

I will work on the 0-60 times for you,

Fuel milage will be about the same depending on how you drive but you could increase fuel milage under a towing condition.

The big thng between the Whipple and the Radix kit is the intercooleer.

I had a customer install a Whipple on one H2 and a Magnacharger Radix kit on another H2. The Whipple made 36 more hp with 5.5 lbs of boost than the Radix at 8 lbs of boost. Boyh were running an Xtremeflow exhaust and cold air intake.

The Whipple will need the flash programming to take ot the torque management.

The Radix kit has its own programmer for the vehicle that comes with the kit but it doesn't take out the torque management all the way.

Both kits work great. The biggest thing about the Radix is that it is noisey. It is a roots supercharger so it does make more noise a more heat than a Whipple twin screw supercharger.

Anything else let me know...
