Close...but not quite. The 7 lb "Low Boost" kit produces only 280 hp by itself. To get around 330 hp you will either have to go with the higher-boost original kompressor Kleemann offers or add to larger fuel injectors and intercooler to the low boost kit to make those numbers...

Roadster,

Good luck but since it looks like you just bought the car be prepared for quite a bit of down time with the vehicle along with having to work thru quite a few "bumps" out...Can it be done?...Sure, but just be prepared to what your going yourself into.
I've worked on a some late-model domestics, japanese and in the recent past; M.B.'s and can say the benz's are the most challenging just based on the computers control and bi-polar mood that they seem to display when doing mods.

 

I'm not looking at doing anything right this second > I only have 1k miles on the car. I would like to change the springs and the chip. It's hard getting use to the power. Going from 570 hp to 215 hp is hard to get use to. I'm not much of a hot rodder on the street > but love to have the power when and where I want it.

First I have to find a place to get a chip made > I'll do a search...

The addition of the supercharger will not effect the redline, although we do offer custom ECU upgrades for our supercharger system ($1000.00) which will add about 20 more HP and I can raise the redline of the engine 300 RPM. Our supercharger does not require any internal modifications- our system is basically a bolt-on system. Fuel mileage will decrease under "normal" driving- not drastically though, maybe 2-3 MPG, depending on the way you drive. We incorporate a bypass valve, which allows the supercharger air to be routed back into the intake system which reduces load on the engine/supercharger, and also improves fuel mileage. The supercharger will not increase exhaust noise. Our supercharger was designed to function perfectly with all stock engine components, i.e. exhaust manifolds, differentials, hood, etc. You can try accessing our new website which should have additional information regarding our V6 superchargers. Because we are a Mercedes-Benz tuning company, there won't be any specific information listed about the crossfire. The Crossfire is based on the R170 SLK platform, so just choose the SLK link, and you can view additional information.
The warranty question is a sensitive subject. I'm not familiar with Chryslers warranty, but according to the Mercedes-Benz warranty, whenever you increase the output of an engine by more than 10%, the drivetrain warranty will be void. KLEEMANN offers a one year, unlimited mileage warranty on all KLEEMANN components. To date, we have had zero engine or transmission failures.
As always, please let me know if there are any additional questions I can answer for you.

To answer your questions:

1. The AMG supercharger found on the Crossfire SRT-6 will fit the non-supercharged V6, however at great expense. not only do you need an engine wiring harness and ECU, but you will also need to lower the compression ratio, which basically means you will need to tear down the engine, and put the AMG spec. crankshaft, connecting rods and pistons into the engine. KLEEMANN's supercharger does not require any additional wiring harness or ECU, nor does our system require the lowering of the compression ratio. The AMG supercharger runs 1 BAR of boost (about 15 PSI), where the KLEEMANN system runs .5 BAR (or about 7 PSI). The intercooler KLEEMANN uses is about 40% more efficient than the AMG unit, which means less stress on your engine. AMG lowers the compression ratio, because the have to, due to the amount of boost they run, and their relatively poor intercooler.

2. KLEEMANN has been producing these V6 superchargers since 1999- before even AMG decided to add a supercharger to the 3.2L V6. In that time we have had zero engine and zero transmission failures. It is a common misconception that one needs a standalone ECU to properly tune a modified vehicle. KLEEMANN uses a mechanical increase in fuel pressure referenced by boost pressure to handle fueling. As boost is created, the fuel pressure will rise in a linear fashion. By increasing fuel pressure, more fuel will flow through the injectors and the injectors are able to keep the identical duty cycle and on-time as a stock vehicle. The ECU (it's not a Daimler Chrysler product, but a Bosch unit, using proprietary Mercedes-Benz coding) is adaptive, meaning based on driver inputs and inputs received from engine sensors, it will automatically adjust timing, fuel, etc. based on these inputs. Eventually it will learn specific "maps" based on your driving style and ambient conditions.

Have we done a crossfire yet? The answer to that question in no. However, the entire drivetrain in the crossfire is taken directly from the old W170 SLK- series cars, which is also the same as any other V6 Mercedes-Benz made after 1999. Like I said before, KLEEMANN has been producing and installing these systems on V6 Mercedes-Benz cars since 1999 with zero failures. It is my personal opinion that one should take with a grain of salt what one reads on these internet discussion forums. Yes, there is very good information available, however there is also some very misleading and incorrect information as well. KLEEMANN has 20 years of experience producing supercharger systems for Mercedes-Benz vehicles. This is a World Wide company with distribution centers on almost every continent. We take our business very seriously, and more importantly, we make product reliability and durability the #1 priority.

As always, please let me know if I can answer any other questions you, or your fellow Crossfire enthusiasts may have regarding the addition of our supercharger system to your vehicles.

Bob,

What part is conflicting?

The low boost kit gives you around 280 hp for around $7,500 and the high-boost kit to which he's referring to at $9,500 gives you the 330...

 

Their web site says "The integrated intercooler has been removed." Also in the 5th paragraph is says "Mounted on top of a 5.0 liter normally aspirated V8-engine, it immediately enhances the engine's power output from standard 306 Hp and 460 Nm to up to 506 Hp and 675 Nm" If you look at the chart and compare the info from the paragraph you can see they are talking about the kompressor system and it says on the 3.2L V6 makes 331 Hp. So the info they are telling you about is the regular not the New Low Boost system. But granted all their systems are low boost, but the new and cheaper one will only put out 280 Hp. Here is the page I got my info from.

It's all about the inter-cooler! The cooler the air the less you have to worry about. The AMG cooling system is poor. I have played with blowers and turbos for 10 years or so and know this for a fact! Any roots style blower usually has poor results with making really HP. A centrifugal force super charger with a big inter-cooler will always work better than a root style blower. I have uploaded some pix of how simple the plumbing would be. These pix are from an LS1 T/A. They have even less room in the engine compartment then we do. I agree with what the Mercedes guy stated above > a bolt on charger with less boost will make more power with the power of cooler air.

What I meant by conflicting is that you said, the 330 hp was NOT the 7 lbs boost, whereas it is! 7 lbs IS their high boost unit and that is why it doesn't need the internal beefing that a higher boost unit requires, it is a bolt on! The 280 hp is only 4 lbs boost. I e-mailed Kleemans to be sure that you didn't have some information that I was unaware of and here is the answer from Cory just to clarify:

Hello Bob-


We do indeed have two kompressor systems available to choose from.


The high-boost, intercooled system will increase HP to 330 on 7 PSI of boost ($9,500.00)


The low-boost, non-intercooled system will increase HP to 280 on 4 PSI of boost. ($6,000.00)


So to answer your question, in the email that I wrote you, I was referring to the high-boost (7 PSI) intercooled system.


I hope this helps!


Warm Regards,

As you can see, all the info. I supplied is correct as I was always talking about the 330 hp unit. I hope this helps.

 

$9,500.00 is pretty expensive for a little over 100 hp. With simple math > 95 bucks per 1 hp. That doesn't include installation or at least a hug. I still think a STS Turbo system would be the way to go! When you buy the Mercedes name > it is not cheap and not worth the badge either. Quality is important > but not that hard to find! I was wrong in my other post > I didn't think the charger was a roots style (twin screw). They make HP at low RPMs but lose steam when others are just getting started. Look at the attached pic. This is some good reading!!!

 

04Roadster tell me, what are you suppose to do if it rains? Have you ever herd of hydro lock? So forget about going to the drive through car wash. Another thing have you looked under our cars? Just how do you plan on routing the piping for that thing? What's up with not having a BOV or bypass valve?

 

ls1 guys say hydro lock isn't a problem. any questions about this should be posed to ls1 guys because they are most popular on those models. also, bov are almost never necessary in street apps only in super high hp situations.

 

Ok how about a bypass valve? I'm sure your TB isn't going to like the pressure not to mention the turbo really isn't going to like it. If it was me I would be putting one on. It doesn't take much to mess up a turbo. Heck they don't even like spooling to fast, thats called surging, let alone stalling. About the hydro locking, I did notice a snorkel kit on their web sight, but I really don't see it working on our cars. You would have to run it back to the front of the car, and I don't think there is room for the piping already. The only hope would be in the rear fender wells and I'm not sure if that will work.

 

these questions should be posed to the company or ls1 forums. no on here will have answers.

 

In the picture I posted > there is a Mondo bypass valve. Look again. I think hydro lock is very very very unlikely to happen. If you drive your car thru a small pound > then you will be screwed...lol. It looks like you have limited room under the hood and under the car > but trust me > there is plenty of room for plumbing for either a rear mounted turbo or a side mount procharger. The best thing about a procharger is they are self contained! No tapping into your oil pan. I'll find some more pix of some tight spots where room was found. The biggest problem I have found with getting a charger mounted to this crossfire is my wife...

 

Here are some random pix of how the procharger mounts to an LS1 and some intercooler pix.

 

i like the zip ties on the supercharger and trans lines! haha! in the first picture! The crossfire is still kinda new, but i think more companies will have superchargers out soon, the procharger's really do sux i was going to put one on my dakota rt but found they lack serious power for some v8s the paxton is a much better supercharger even though u have to tap the oil. i think the sts turbo system is going to be the best to go with yet! i already talked to sts they said there a universal kit all you have to do is get the tube from the turbo to the intake piped and tuning and injectors.

 

Really they sell turbos, just kidding but isn't that just a turbo?

 

na you get the turbo the exhaust system, oil lines, oil pump, i think some couplers, blow off valve, boost controller and gauge.

 

Yea the STS kit comes with just about everything you will need. If you only push 7 psi of boost > you shouldn't need injectors. Don't quote me on that... I would think a boost reference fuel regulator would be enough. Like this one in the picture. Or an FMU.

 

Wait guys... I don't see where STS even offers an application for the Crossfire... Are you talking about taking one of their products and doing a custom install ? If so, there are many other TC mfg's that produce a product that would better fit our car... If you want to spend a week doing custom fitment and have a machine shop that can do fabrication it is all good...

But don't forget the all important turbo headers, maximized injectors, FMU and Fuel Pump... Now you're talking FAST>>>>

OK, here's a wacky idea... Since this topic has been discussed for nearly three years, and nobody has had the extra cash laying around to get the job done... $10-15k why don't we ask all forum members to donate $10 to a S/C mfg. to develop a kit for the car. I think there are about 3,000 members... Do the math and I bet we could get a great kit, real fast... Power in #'s...
