Hello

Does any one have any idea what is available for a SL600 to bring it into todays performance catagory. Is there a bolt on NOx kit available. I would like to target 0-60mph in under 5.0

John Roncallo

There would be nothing avalable in kit form for the M120 unless you go to Renntech or AMG. You would be looking at $30K - $50K for thier mods. Tell me how much money your willing to spend and I'll give you your options.

What could be done for under 5K.

John Roncallo

You could get a supercharger system built for about that. I would think you could also buy and install a NOx kit for that price, but that is alot of stress at once.

it's automatic.

Who could build a supercharger system for a MB V-12 for that kind of doe.

John Roncallo

I have a friend who does CnC for a living. He also does custom fab, and he is going to mak me some headers for my 190E too. He said if I get all of the required secs, he could get it done for me cheap. The most expensive part of the system would be the actualy supercharger. A guy named typhoontaz here has superchargers on his SL600, so you should look for him to get more guidance. I will see if I can pull his post so you can get some more info.

What kind of injection is on an M-120. Are bigger injectors available.

J. Roncallo

I am pretty sure that it has the motronic setup. As for bigger injectors, I couldn't tell you.

$5K for a supercharger installed and working correctly would be very difficult. The cheapest way to supercharge would be to use 1 or 2 centrifugal SC's and run low boost, around 4-7 psi. This should get you into the 5 second range. I would budget at least $8K for this project. The most inexpensive way would be nitrous, 100-150 shot should do what your asking without having to modify the stock EFI system. Just make sure you have adequate safety peripherals such as wide-band O2 sensors in conjunction with your power adders. Killing an M120 would not be good on your wallet. There is better injector technology out there and you can run slightly larger injectors. While you may gain better throttle response with this expensive upgrade, it will do very little in the way of HP. Getting more air to your engine is the trick, fuel is the easy part.

I have to agree. The layout of the engine lends itself to a two supercharger system unless ther is more hood or forward clearance than I'm imagining. I havent seen one of these cars yet.

I'm not familiare with Nitrous systems. I belive to install one of these systems I would have to modify the intake to accept a small injector into each cylinder or one large injector on each side. Is this correct. Not exactly a bolt on but doable. I also belive that extra power from Nitous requires extra fuel flow of gas, meaning larger injectors. Is this also correct.

John Roncallo

An when the NOS tank is empty, you are back to the same dud you started with. Making "REAL" power with nitrous, requires a lot of gas. One of my big inch Chevys used a five pound bottle in 300 feet. The typical NOS system comes with a 10lb bottle. Blowers are the way to go. Injection is nice, but I'd rather be blown!

That's correct, when using nitrous on your M120 you have a few options. Your can run 2 nozzles wet or dry... Or... 12 nozzles wet or dry. The easiest way would obviously be 2 nozzles. With only the need of 150 or so HP shot, 2 nozzles will be adequate. Running dry is the dangerous part. Using the injectors to supply extra fuel from the injectors during the nitrous injection is a sloppy solve. A dry nitrous kit raises the fuel pressure to the injectors, thus providing a higher volume of fuel. You could run a wet 2 nozzle system however your manifold is designed to be dry, not wet with fuel. That's why it may make more sense to run a 12 nozzle system and spend the extra money. It's your decision.

That would be next to impossible unless your 300 feet is one big slow burnout. Please explain.

Then again the SL600 is still faster than 90% of what you meet day to day. LOL.

It shouldn't be too hard to add the S/C as it's mostly the brackets as mentioned above.

Not hardly. Sand dragster, 600cid,8500rpm. Five pound bottle packed in dry ice, full at the start, empty at the end. Race is 100yards, 2.5 seconds or so.
