Need Advice on Adding More Power to HPS SC
I would suggest doing at least a poll on the forums if not thoroughly studying the market first before jumping to conclusion. Wishful thinking can mean a lot of wasted investment down the road. A lot of the buyers of pre-owned Benzes are still older folks that might not want to take the risk of s/cing their car or they might simply not need the extra horsepower. To be honest with you, it's your investment and I have nothing to do with it so I really don't care how much you can potentially lose in this venture, let alone being against it.

1) Sharp, Jagged edge design of Outlet Plenum traps air in the corners.
2) Not enough space inside the Outlet Plenum to circulate air with intercooler core taking up half of the space.
3) Too much turbulence and back pressure inside.
4) Polished surface retains heat.
5) Not enough surface area to dissipate heat.
6) Inlet Plenum design causes air to clash against each other from opposite sides at the T intersection. Needs a SL55 Splitter design to channel incoming air into SC.
7) Air must make a sharp 180 degree turn inside the Outlet Plenum to reach the Intake ports.
8) Outlet runners are TOO SMALL and SQUARE in shape.
So bottom line is I'm done with this kit. Jessie did his best but was only able to squeeze out 438rwtq but the rwhp was just shy of 400. He did not want to risk blowing my engine so he did not advance the timing too much.
Looks like I'm going to see if my brothers and brother-in-law are willing to invest in starting a company to build one from scratch using the Eaton TVS blower. I've learned from the flaws of this kit to know what NOT to do. If a kit can be offered that is reliable and makes Kleemann type power for under $5000 would there be a market for it? Of course we would recruit the very best designers and tuners in the industry if there was enough capital poured into this venture. The kit components can be fabricated in China. Quality can be tightly controlled. The Design and tuning would be done here. Remember we are talking about the used MB market here. All the Non-SCd C, CLK, SLK and pre-2003 55's around the world will be the potential market.
Things aren't as simple as having an idea and 'raising capital' by getting money from your family.
If you want to throw away even MORE money on another failure, sure, I'll watch.
You are nothing more than an insecure C32 owner who cannot bear to see C55's extend the power and speed advantage once it's been modded. Why should C32's be the only C class cars than can be modded with significant power for a reasonable price? You feel that Kleemanns and Renntech blown C55's are few (AMGdragon, BennyZ, Catapult, etc..) but the thought of a mass of C55's making at least 50-80rwhp more than your modded C32 frightens the living daylights out of you.
First of all, my suggestion was directed towards the thread starter who needs help with tuning and asked specifically for that.

Looks like some real answers should start coming out......
Everyone knows Powerchip and Stealth Auto share an office aside from you. I have mentioned such numerous times, nothing is a secret.
Members arent smart and arent able to search google to find some quick answer too right
Most members on this board are VERY smart which is why they see my repeated posts about sharing an office with Powerchip.

Some members feel the need to hound companies and provide false information when they themselves have no first hand experience.
You my friend came into the Powerchip thread I created to simply bad-mouth them and try to make me/us look bad.
Again, thank you for the above mentioned links and at your attempted degradation but unfortunately such did not come to fruition.

That last post where you claim to be bringing a blower to market for a MB made my almost spit my breakfast on my screen I was laughing so hard. Do you really think ANYONE would buy a car part from you? You have proven yourself to be a car destroyer not a tuner. I would really doubt anyone here would want a part you sold over something offered by renntech or kleemann - regardless of price!
You fall into the group of people that think they can become a car tuner over night with a few shinny parts and a showroom (aka HPS!). If you do come to market I predict that it wont sell and your venture capital will all dry up. Did you learn this monkey business at USC? I though that place was better than that.
Kev has a fantastic point about making parts for a out of production motor. I made this point to you a very long time ago but it has come up again and it is quite possibly the most important point yet.
All the other tuners got in on the tuning the M113 back when there was demand. People will not want to put blowers on used cars and most people buying a used car are doing so to save money. People trying to save money normallly do not want to go out and spend 10k on a blower and some other upgrades. RENNtech and Kleemann had a nice run with the M113 motor serioes and now its about done. They are not working on the new M272-M273 motor for that is where the proffit lies. Good luck.

It sure looks like your project was to build a blown C55 comparable to Renntech and Kleeman for less money. In that sense, you failed. Failures happen to all of us. It took you way too long to accept that, but it looks like you finally did. Now you're talking about starting another project that already has failure written all over it. As much as I would love to just sit back and go 'glad that's not me,' I still want to slap ya and tell you to stop before you start.
Your attitude about the C32 vs C55 thing really speaks for itself.

At this point, I am just going to use my car to build a prototype using the Eaton TVS 6th Generation blower. If it works then I will feel out the market reception of a under $5,000 MB SC kit within PROVEN POWER and RELIABILITY. We would also consider the new applications for the new 4-valve motor as well.

No. My strategy is NOT to offer it for 10K but for the price of a C32 Stage 2. Why do plenty of C32 owners spend over $5K on pulley kits and software alone when a C55 owner can potentially get a Supercharger w/software for the same price? Outragious? Go Check SuperchargersOnline.com. Practically every Supercharger for all other makes sells at no more than $6-7K.

I was merely stating what the pre-requisites for a successful launch would be. That it had to be thorougly tested and proven before it goes to market.

People who buy a used car buy it to save money and likely will not want to spend that much on your blower - even if it is ultra cheap. I think people here have seen enough go wrong that none would want your parts. HPS never was a profitable project and I doubt your plan will be profitable as well.
Your ability to design and trouble shoot issues has lead to your car being a horrible failure. You finally said that the blower is junk and now you are back to trying to make the new generation work.
Adam went into the car field with NO background in the car tuning business and look he is in court and losing money left and right. You have no background in this and for some reason you think you can come in like a master and bring the worlds best item to market. Sorry for being skeptical but I have doubts.

Got to give the props where it is due.
He said it was custom work but it was done in 30 minutes and then slapped on the dyno. That is not the way a custome map works. It is not a simple series of key strokes and there you have 100 rwhp.
So if his car is indeed making that power then leave it alone and be happy! Its doing what kleemann and RENNtech do. I still do not trust these figures however.

The torque is impressive based on what he told me but he said the power just flattened out before reaching 6000rpm. I guess these roots blower have very poor top end compared to twin-screws and centrifugals.
I cleaned out my K&N's yesterday and it was filthy. I also noticed that the plastic air ducts was not properly aligned (did not snap in place) so about half of the openings was blocked by my grill. I hope that's not what was causing me to run rich.

I don't have access to the tools needed to reprogram the factory ECU, otherwise I'd probably give it a shot on my c32.
