agreed. :)

[aintME]

so it's an extra $500 for the warranty? is that an extended warranty for the SC or $500 for the full factory warranty? how about the CARB certification for us CA folk?

taken from HPS website
We offer do-it-yourself mechanics a complete supercharger system for $7,500. All parts and instructional manuals provided along with technical support. Parts and supercharger warranty included. (No factory warranty.) Signing a waiver is a requirement for this April special.

Or

Our normal supercharger system with a full factory warranty, which include all components, CARB certification for $8,500. Plus $1,495 for installation by an HPS authorized dealer.

really? so, what's your take on it? i'm more unsure on which package they are offering. i guess what is throwing me off is the no warranty statement which coincides with the DIY package, which doesn't state CARB certification as one of the components. also, what is the extended warranty for? are they offering their full factory warranty at $500? or just an extended warranty on their SC? i'm not trying to clown them or anything. i'm actually considering it...

[Dr. ///AMG]

When I talked to Adam, he told me that the warranty they offer is an extension of your current Mercedes warranty. So your car HAS to be under warranty from mbz, and then they extend it 4 years.

That's what I understand.

the 4 year warranty applies from date of purchase when new. When your "new car" warranty runs out, the aftermarket arm does also.

Run.exe,

We offered a June clearance special to move existing inventory before purchasing larger lots from Magnuson Products and other suppliers. By doing this we obtain a larger discount = lower price to the consumer.

High Performance System LLC is a sub-division of a successful aerospace corporation.

Currently our website is being updated & uploaded to provide current news, specials, and other products available. I do apologies for any confusion our website has given. As you know it’s hard to find good help these days.

HPS offers two warranty policies; One is a 1 year unlimited mileage for the supercharger system and all hardware components. Second is a 4 year 48,000 mile (Which ever comes first.) factory warranty that is underwritten by Deli Financial.

The one year / unlimited mileage is given to every supercharger system sold. The factory warranty is offered for additional $500 dollars.

[HPS II]

Dr. AMG

Yes, if your vehicle is under the original OEM 4 year / 48,000 mile warranty, we can give you additional 4 year / 48,000 mile. (Which ever comes first.) A 2 year / 24,000 mile extension are available for a small fee.

I’m working now to offer a new policy that co-exists once the original warranty expires.

All I can say it that you guys really need to add an intercooler and fab a bracket for the M104 and your business from this site will go through the roof...

I hear you. If this system had an intercooler...I would be so on it!

Kodiak, I said M104 many many times, but they're focusing their work on things like W211 500 and such :(

I know. What I was told was that it was kinda not the smart business move to spend $30k on R&D for an older model. But when you look at it, how many of us with an M104 would love to get another alternative to dual hair dryers?

Hello Turbo,

Why? Because our system doesn’t use an intercooling system. I have a question for you, do you know when and why to use intercooling?

I understand on all three forums our competitors suggest bypassing intercooling will lead to overheating and detonation. Even though they lack any if all real data proving so. If you did your homework you would realize half the tuners in the world don’t use intercooling. For example Jackson Racing, considered the top tuner in the world for Honda and Acura, run a 5PSI or boost system without intercooling and experience no overheating issues. So why would a HPS system running a pound less over heat?

Over $15,000 dollars was spent too instrument both the 430 & 55 models. We use DAK1 an Air/fuel ratio and data acquisition system for measurements. It is a multiplexed data acquisition system. It’s the only system that includes data acquisition with temperature compensated air fuel ratio measurements. This system provides 19 channels of data acquisition, 14 are programmable analog inputs: Voltage, pressure, temperature, TPS, MAF, and etc. Not to mention a temperature compensated lambda probes and displays the air fuel ratio.

We had a performance test on our E430 driving 90mph for over 50 minutes and data being taken at speeds above 135 mph. Data showed an increase of 18-22 degrees. This data is critical to prove INTERCOOLING is not necessary for our system. Not to mention countless of other tests.

I would believe raw data our company supplies than what the competitor suggest.

LOL.. perhaps not relevant, but my Turbo GS-R doesn't use an intercooler... but guess what? It's bogging like a mofo now that's 90+ degree weather everyday + A/C on...

I'm calling my GRreddy guy asap for the front mount. hehe.

What boost was used on your GS-R?

Second there is a big difference between superchargers and turbo. Even though you probably know this, I listed a few basic facts for other members.

Superchargers force more air into the combustion chamber than the engine will draw in its naturally aspirated condition. Whereas turbochargers are driven by exhaust gas flow, superchargers are driven directly off the crankshaft, usually by a belt. There is a common misconception that turbochargers give you "free power" but in reality having a turbo interrupt your exhaust flow is like having a cork in your tailpipe, it takes engine power to force the exhaust out past the turbocharger. Turbo usually run boost in the high 9’s and low teens and generating more heat than a supercharger. That is why intercooling is recommending.

That reminds me... Let me find out some infos.. Will send you an e-mail later..

Personally, for me I want to run a higher PSI than your 4. The only way to accomidate that is to use an intercooler. My car is now equip with the ability to add in additional fuel injectors if needed, and I am also able to program my ECU to retard timing up to 12 degrees if necessary.

I like the system, however I want more than what HPS or Kleemann offers stock.

I have been bombarded with other things, so I haven't been able to really dig in on a custom frabrication.

Hello Turbo,

A lot of aftermarket enthusiasts are falsely led to believe that more boost equals more horsepower. Which is really a misleading statement.

The key to a high efficient reliable supercharger system is airflow. Our engineering staff spent thousands of hours developing this type of system. The HPS supercharger generates up to four pounds of boost, utilizing a highly efficient intake and discharge system that increases airflow. This level of boost allows for lower supercharger discharge air temperatures – cooler air is denser, allowing more fuel to be added to the mixture, thereby increasing boost efficiently. This also eliminates the need for costly intercoolers and increases reliability by not requiring redundant systems, which could fail.

During the R&D stages of this project we toyed with different angles & specs on the casted hardware and discovered anywhere from a 30-75 horsepower difference. See Turbo, to generate boost, all you have to do is reduce the pulley. That's it, very simple. However to generate the proper airflow is the real key. A while back I watched a Holly blower pushing 6.5 PSI on the dyno and the results were only 60 horsepower. And I can go on and on and on.

Regarding Intercooling, I still think your missing the boat on when and why to use it. If you like I can forward this info?

If HPS or Kleemann can’t meet your expectations, I suggest contacting Renntech. For 30k they’re give you a nice system.

I enjoyed meeting you at our open house back in March.

Good luck!

My understanding is that the intercooler is to decrease air temp to allow for more air. Which requires more fuel to maintain 12.5-13 AFR.

As I said before, I had a RX7, as many people have done. Increasing turbo size, and intercooler size requires additional fuel as well as retarding the ignition which in turns increase HP. Of course all these HP ends up being at the high revving range of the engine.

So my basic understand applies. If I want more than 4psi of boost, of course I change the pulley...but with the increasing RPM of the screws, it will create much more heat in the chamber. Which will require some sort of cooling. Because of the increase air, the fuel delivery will need to be increase. The question is what type of temp are we expecting to see the supercharger create @ 6psi+.

Hello Turbo,

There are a number of factors that affect the temperature increase that occurs when the air is compressed. Firstly, the higher the boost pressure, the greater will be the temperature increase. As a rule of thumb, if you are using a boost pressure level of more than about 0.5 Bar (~ 7 psi), an intercooler is generally a worthwhile investment. Of course depending on how the system was designed.

Secondly, the lower the efficiency of the compressor, the higher the outlet air temp. However, it is difficult to accurately estimate the efficiency of the compressor and even if such a figure is available, it doesn't necessarily apply to all the different airflows that the compressor is capable of producing. In other words, there will be some combinations of airflow and boost pressure where the compressor is working at peak efficiency - and other areas where it isn't. While a well-matched compressor should be at peak efficiency most of the time, in some situations it will be working at less than optimum efficiency. This will change the outlet air temperature, usually for the worse. This is why it’s critical to have an efficient supercharger system.

An intercooler will do two things - it will lower the temperature of the intake air and at the same time, cause a slight drop in boost pressure. The latter comes from the restriction to flow caused by the intercooler. Some restriction is unavoidable because the flow through an efficient intercooler core needs to be turbulent if a lot of the air is to come in contact with the heat exchanger surfaces. However, if the pressure drop is too high, power will suffer. A pressure drop of 1-2 psi can be considered acceptable if it is accompanied by good intercooler efficiency. But will it run efficient? If not you can lose more psi. Picture this Turbo, we run intercooling on our 4-psi system, due to backpressure we lose 1 psi. Yes, the temperature might cool 5-10 degrees but you lose anyway from 20-25 horsepower. To solve this problem, you’ll reduce the pulley, generating more boost, to compensate backpressure to 4 psi. So nothing is really accomplished except the compressor is spinning faster and the cost for more hardware.

Even if you run warm at 50-80 degrees as long as your AFR is maintain and fuel management, detonation will not occur. I think in the past many hot rods by-passed fuel management and ultimately burn up a piston or cylinder.

I mention before turbo are driven by exhaust gas, and run high boost in the low teens 10-14 and need intercooling due the extreme temperature.

On many occasions we ran 5-6 PSI by reducing the pulley on my s/c 2000 E430 sport and only saw temperature increase of 35 degrees. Nothing! I mention before, it’s all about airflow.
