Need Advice on Adding More Power to HPS SC
Is it a worthwhile venture? Would anybody be interested with a product like this?

No.
Why?
You seem to be a good guy, but then we read about your HPS debacle. But you still stuck with them. Why choose an inferior product over something that is proven to work reliably?
This speaks tons about a product you may market in the future; that you'll settle for something inferior and keep working on it, even though in the end, it's still inferior.
BTW - what do you mean "the only ones with the SL65 programs"
1) How many people have SL65's... so this helps us how?
2) What about RENNtech? Or are they selling a bootleg SL65 ECU?
No.

I'm not trying to down on your project, it's just when you say stuff that is questionable which kills your rep.
The Best of Mercedes & AMG
Josh R's and Mario's car runs fine on stock ECU programming. HPS tried to compete with Kleeman by copying their design and failed. I'm sure people would jump at the chance to get a kit from people like Hartmut, who actually know what they're doing since they are car mechanics themselves. People do not pay 2-5 times more for a supercharger kit for the ECU, they pay for a kit that will run reliably without unnecessary software changes. Case in point, look at Catapult's Kleemanized C55; he did not have ECU software installed with his Kleeman supercharger and headers. ECU tuning is a joke if you think it will fix a problem with the supercharger kit. I don't care if you have access to SL65 ECU map data, etc. It is a totally different car and engine.
It got screwed over with lies, cheaters, and ego.

you bought them, then you would want someone to pursue this.

Robert if you do this kit, make sure you start completely over, do not salavge anything from the HPS II kit.
Of course if you, or your customers, don't care about "Check Engine" lights ...
So I have to respectfully disagree with you Pshek and E55cent. Of course you need a decent kit to begin with ... (DUH) Also with the older Mercedes I can see how you would feel ECU tuning isn't a key part.

Even Kleemann advised me to get the ECU version of the kit for my 2006 model. ECU remapping is without a doubt necessary to get any power.
btw..Has Catapult ever posted a pre-ECU dyno with a post-ECU dyno? I'm sure it would make a world of difference. When I first got my car back from HPS without chip tuning, my car felt stronger too and was running smoothly with NO CELS but it only made +20rwhp when I first dyno'd it at HOP.
After Jessie tuned it, I re-dynoed it HOP on April 15th Dyno day and everybody there witnessed a healthy gain from ECU tuning alone of +63rwhp and Jessie did this by just Trial and Error remapping! Chip tunng makes a HUGE difference.

I am not necessarily bound by a Roots-type blower since everywhere I read that the twin-screw is efficient but is more expensive to produce because of the close rotor tolerances which can also make it less reliable.

The fact that you say the stock intake and heads flow well shows you really don’t know much about these motors. The stock head flows very poorly. 3 valves per cylinder is far from ideal and was only used for quick warm up of cats for European emissions laws. MB thought they could not make the M119 style quad cam motor work given the new laws and went with a fairly low tech 3 valve design. When all other automakers found a way to continue using 3 valves per cylinder mb realized they made a real mistake. A 5 L V8 3 valve engine made 302 hp but a 5 L M119 made 322-350 (and that engine has been in production since 1989). If the stock kit flows so well why does everyone make new air-box's to increase flow? Why does a port and polish yield some serious gains?
If I had a 60k C-Class, 90k E-Class, 110k S-class etc the last thing I would do is send it to a company trying to copy the real professional tuners. We did not cut corners in buying the car (we don’t drive fords here) so I doubt we want to save 5k and get a fly by night blower kit installed.
In my take you are trying to build a part no one wants. Your ideas seem questionable, you are working with a blower kit that has shown its ability to add no power at all, and you also fail to realize that the 3 valve motor is now out of production.
So the car you want to tune is not being made anymore and you want to build a kit? Most car tuning is done on new vehicles because new car customers have the cash to buy upgrades. Not many people buying a used C55 or C32 for 32k have the cash or desire to buy a stack of mods. A few customers will exist and therefore I see a failing business plan here. You need to have an existing company capable of working on future designs not trying to play catch up with the existing tuners. RENNtech, Kleemann, and Brabus already mastered the M113 motor and they now are moving on to the new quad cam motors. They spent the last 9 years mastering this 3 valve motor and I trust their work.
Save some time, money, pain, suffering, and effort and just send your car to RENNtech, Kleemann or Brabus and get it done correctly.
Economies of scale. When you only sell a few kits you have very few customers over which to allocate your R&D costs and the parts you sell tend to be very costly. Adding volume will lower your per unit cost to customers but this market has a very limited customer base. MB parts are not so expensive because people are trying to screw us. Its is because they need to make some money and have very few customers to sell thier products to. Its not like making a honda civic cold air intake where you can sell hundreds of thousands of units.
In this business of tuning 75% of what makes a tuner successful is his reputation, past experience, knowledge, and longevity. I don’t see the kit discussed here as being able to succeed in making a customer feel comfortable that is its biggest flaw -- other than the fact that the blower seems very poor in both quality and design.

The custom ECU will also be reprogrammed by a new tuner if there is time this Wed-Fri.
As you know, I am one of the few guys on this forum that always posts the actual dyno results. Good or Bad.

from the hps site....
Specials:
Used 2nd generation intake supercharger systems available. Contact us for more details.
Note: HPS performance testing is conducted under laboratory controlled conditions. The performance values quoted apply to certain models only and not all models will achieve the same results. Actual customer vehicle performance values may be higher or lower than stated due to individual customers' vehicle condition and other factors beyond HPS' control. Unauthorized vehicle modifications may also affect performance.
Due to supplier issues, HPS can no longer continue to work with Speed Innovation and/or Jessie. HPS will not be held accountable or responsible for any tuning issues from this company/individual on any HPS vehicles. This will include but not limitd to the following: Any internal or external engine damage including the entire drive-train, transmission related issues, failed vehicle mass air flow meter sensor including related emissions control system components, ECU computer issues (Hardware & software related anomalies), and/or other related components. If a HPS customer choose to use this company and/or individual even after reading this statement you are at your own risk. You also release/waive all your rights and/or claims against HPS. You also void any remaining factory warranty from HPS and are on your own. This information is written to protect HPS and a friendly reminder.
Anyway, just my Opinion looking from the outside. Thanks
Don't go cheap with the S/C and end having to spend the same KLEEMAN $$
I think is funny how they still have the power gains created by ecu tuning from a certain company. They still claim the numbers over the phone yet without the software it wont happen in my opinion.
Also based on his additional warnings about warranty does that mean that the rest of the holders of the product that are using the tuning successfully will be denied of warranty because the tuning makes the vehical run correctly.
Based on the ecu tuning numbers and the fact they still use those wouldnt that be false advert.
Last but not least of course you would ask everyone who is interested in purchasing the product to stay away from me, im the only one that can make it work.
Oh theres more and more
He in short will have a surprise coming
I have forwarned this individual about his emails which are derogatory and agressive in nature. Not only have I warned this individual about his method of " Harassment " but I have asked him to stop emailing me as the contract was terminated due to unforseen hardware issues. I have in writing where I have asked this individual to stop the emails but he doesnt listen.
Unfortunately for him and fortunate for me was his last email to me.
OPEN SHUT CASE PER SE
P.S. Based on the content on HPS site which is copied now in case he takes it off. There will up for grabs a new case for those who are attorneys and are interested.( Libel,Slander etc
Good luck on the cases AF and Sean if you read this please contact me I will discuss it with you then
