who's running a supercharger?

[BADRAP]

I have considered for sometime about buying a supercharger and I think that this will help my decision. I know that Whipple is suppose to be awesome but after reading this I will have to do more research on this.. I like them both that is the Whipple and the Magnacharger.. They both sound tempting.. I want improved fuel mpg and better HP and it seems as if they will both do that.. So were I go from here is still in the air....

I have the Whipple on my H2 and it works great. I live in the Caif. desert where the temps are now 110+ and I have never had an overheating problem. Yes you do need to have the PCM programmed and you need to have all of the torque management programmed out or you will never be happy with the way it runs. I used Ed Wright for the programming and it turned out great. I also had him firm up the shifts, change the shift points, etc. My mpg has picked up a little possibly 1 mpg. The boost will go to 6 lbs. with the optional pulley. This mod has greatly increased the performance and gives it the power that it should have had in the first place!

No argument here. I have a faxed copy of the dyno runs. I didn't say I did the test. Ican fax them to you.

This is the Magna Charger Radix Kit? Only 5 psi. Thats what the old side mount kit made that SMA uses. Not the intercooled kit. I have spoken to a few others that have installed the Magna kit and they have told me 8 lbs also.

Did you speak to Steve? Did you tell him that the vehicle had modified exhaust. When you open up the exhaust to a free flowing one, back pressure is less and boost drop depending on the exhaust. The H2 had a smaller pulley on it then what comes on a stock Whipple kit for a unmodified vehicle. It also used the programmer to take out the torque management.

With the Magna kit it is still there.......

Fuel economy has gone down about 1 mpg. It went up about 1 with the supercharger and down about 2 with the tires and lift.

I'm going to get an exhaust on it and run it with stock tires just for better comparison.

Please don't bash my numbers with numbers from someone elses website. Please do bash my numbers if you have accurate runs that you have done in your H2.

Someone needs to answer this. I need the info also. I'll bump it to the top. Suprised Whipplecharger hasen"t jumped on this one.

Thanks NJ

I can now say they exist and I have seen one. Do you think that a H2 would fit on it?

nice! I think the closest installer for me is in South Florida... I'm up in jacksonville. Hey!!! We play you guys on Sunday.... one of our teams is walking out with a freakin win! anyway, I've been waiting for someone to get the kenne bell installed. I didn't have the balls to be first. I'm glad you like it, I'll be getting one real soon. I can't wait to compare notes. Did you notice a good improvement with around town driving? Did it make your H2 feel lighter on its feet? I sold my Ford Lightning, but I loved the supercharger! I can't wait for my kenne bell. Go JAGS!!!

I agree with the boost pressures on the whipple. My Chevy truck never gets over 6 either. I know that 8 lbs of boost is a ton, I mean a ton of boost on a stock pistoned stroker motor running 93 octane. When i install my magna i will get accurate boost numbers and post them. I'll even do it with a stock exhaust and a aftermarket exhaust. I don't want to make enemys over 2 lbs.

Thanks for the input.

Hey whipplecharged.

To answer your question about my shop name.

My "shop" is called Performance Truck Centers. My main location is 12,500 sq feet and my second location is 2,500 sq feet. We are a Whipple installing dealer as well as a Magna installing dealer. I don't have a lot of experience with whipple. I've only been an installing dealer since 1997 and have installed only around 30 kits. This Magna will be our first intercooler kit.

We also have an e-commerce web site but forum rules keep me from listing it.

Some people were asking about Kenne Bell. I have one on my H2. It's nice. I read their stuff and liked what they had to say. It's clean and tidy and does a good job. I run mostly off road, a lot in the Southern California deserts and in Mexico. Lot's of sand dunes. I go on 7 or 10 day trips and don't want to break down, especially in Mexico.

Well anyway, the supercharger and some 37" Goodyear MTR are the only mods on my H2 so far. I haven't done exhaust, headers, etc. I doubt I will. I put on the supercharger because it actually gives more power, more usable power than all the other upgrades. With everything else stock I have enough power to break the car offroad and I don't know how I would put more power to use.

So, I can't answer horsepower questions or all that, but their system makes mechanical sense and I chose it because nobody else bothered to tell me why their system was good, they just said "here's what it costs." Plus, I hate the idea of piggy-backes ECMs and 9th injectors into the manifold.

That's my story. I love the Kenne Bell.

Where is the best source for buying the Whipple? I live in Chattanooga, Tn and will probably have my dealer install the unit.

KENNE BELL COMING SOON, VERY VERY SOON!!!!!

I'm sorry but I'm completely stupid about superchargers. I just know they add a truck load of power, and might add one to my rig one day (hopefully). But i just wanted to know what "5 pounds of boost" meant.

thanks,

H2 Daddy: Thanks for the kind words! Like I've said in other posts, though, the guys who I bought H2's for earned them... :-)

OK, question for all you Whipple owners out there. Upon reviewing the instructions for "installing" the ExtremeFlow mods for the air intake, it appears that we've got to butch up some of the existing intake tubes, box and trim the inner well some. Not too hairy, but I'd planned on trading in my H2 when my SUT comes in, so I'm looking for a better intake solution. Who makes air intake systems suitable for the Whipplecharged H2? Please, no bashing each other, just info needed on a first rate system. I'm less interested in price that quality & performance.

Also, Whipplecharged: Where can one obtain info on the intercooler. It is applicable for "retrofitting" existing Whipple installations? From my previous experience with intercooled turbo-diesels (F-250 and 2 H1's), the flash programming & exhaust stuff added some HP, but the "seat of the pants" torque and gas mileage came after intercooling. Adding an intercooler to my stroked H1 with "Heavy Hummer turbos" (yes, two), I picked up almost 5 MPG!! I had always noticed in my non-intercooled travels that I got MUCH better MPG while motoring through the mountain passes in CO than I did in the (relatively) flat lands of the Texas Hill Country... Of course, diesels are much less sensitive to weight/load... :-) Wish there was a diesel option for the H2... :-\

2slo4now: Can you email me your ecommerce link. My email address is in my profile. Thanks.

Thanks for your input guys! BTW, my initial findings on my individual H2 is that the ExtremeFlow muffler ALONE is resulting a barely perceptible HP increase and about 1/2 MPG increase with everything else stock. I'll burn 3 or 4 more tanks of gas in a short trip over the next few days, so I'll have a more accurate measure by this weekend, when I plan to do the flash programming. If I can find someone to sell me a QUALITY air intake and get it FedEx-ed, I'll put in in on Saturday before leaving for a 2,000 mile trip through CO on Sunday.

Thanks for sharing

I too have been doing some research out of this forum for the last few days. The results are below but first I must confess a few things. I own several truck accessory stores in Alabama. We are a whipple installing dealer. As of today we are also a Magnacharger installing dealer. I wanted some real people feedback prior to making a decision on picking up Magnacharger. Thanks for the input.

I talked to a "friend" that is an installing dealer for both in another state. He told me he likes the Magna much better (on the H2). He has installed plenty of each. I mean plenty...

Here is what I found:

Magna uses the factory computer to control 8 new 8.1 liter injectors.
Whipple uses the factory computer to control 8 stock injectors and a seperate black box to control 2 additional injectors.

Magna adds a 175 liter fuel pump to the system to assure that there is not a lean out condition
Whipple does not

Magna uses a intercooler
Whipple does not

Magna is going to be a lot harder to install. For me that does not matter. For the power hungry when your spending 5 large what's a couple hundred more in labor.

I love Whipple chargers and the company. There are many application where they are still my charger of choice. But on my H2, I am going with Magna. I will have it on in a couple of weeks and welcome other H2 owners to come and drive it. This is not a plug

Here is a simple justification of the price difference between both systems. I seems that selling prices are about $1000 apart

6 additional injectors in the Magna $750
Flash programmer included in the Magna $425
Intercooler.......priceless

I'd love the kenne bell, I just don't want to be the guinnea pig! Does anyone know of anyone else that has installed it on thier H2? I know thier twin screw for the Ford lighting is awesome, I'd just rather wait for someone else to take the $4,000-$5,000 gamble first. then tell us about it. Does that make me a bad person????
