Question on TC/SC and Nitrous
I am seriously considering upgrading the performance on my CLK500. I am looking for the cheapest ways to significantly increase horsepower. I was thinking a turbo would be perfect, however, it seems like nobody has an aftermarket turbo for Mercedes. Anybody have any ideas? I would love to go with a super charger but it seems like they are all way too expensive.
I was also thinking about nitrous. I know nothing about nitrous except that when used, it is supposed to make the car much faster. Would anybody like to fill me in on general info on nitrous, legality, hp gains, problems, setups, prices and manufacturers?
Thanks a lot guys.

SC is the way to go, but you're right it is pricey (nearly $16K). Renntech has a Performance Pkg. 1 (Airbox and ECU upgrade) for a little over $3K. But not sure if that's worth the 21 hp increase to you.
I would NOT recommend nitrous oxide kits. It's a short term speed solution that could cause long term engine problems. Don't know anyone who did this w/ an MB or Audi, but seen them in other cars (i.e. Eclipses, Civics, etc.) and it just causes too many problems and costly repairs from what I hear from those owners.

...It's so depressing...I'm gonna go to a local tuner shop within a couple of days and see what they recommend. If its real expensive or I get no HP gains, then I'll have to learn to live with a lowely stock 302 hp engine.

In my experience, complete turbo kits have always been more expensive than supercharger kits, but that may just be the case with the cars that I have dealt with so far. With that being said, you could always get a experienced shop to put together/fabricate a turbo or supercharger kit for you. That would probably be cheaper, but then you run the risk of running a "unproven" kit. So its not really the "safest" thing out there. You would then have to deal with the ECU, which is a PITA. I'm not sure how the mb ecu's work exactly, but you might be able to completely disable the ecu, and use a full standalone system to control everything. Which after all is said and done would come close to that $16k price tag of the supercharger that is out and proven already.
Regarding the nitrous system, I know a lot of LS1/LS2 guys running nitrous without any problems, but I know a lot of guys with other cars damaging their motor with nitrous. I think you should be fine as long as you don't run too high of a shot, and don't run it too often. If I were you, I would start off with a 50 shot and get all of the safety equipment. If the car handles it great wihtout any problems, then I'd upgrade to a 75 shot, and keep it at that. I wouldn't go any higher than that, even though I think the V8 should be able to handle it.

like Jaki said above, starting off with a small shot like 50-75 should be ok. I have a buddy who had nitrous on his 350z for well over a year and used it almost everyday, haha. He just took it off a while ago and had compression tests and this n that done to his engine and results said his car is running perfectly fine. He had the whole set up professionally done at a place, so in my opinion as long as you know how to use it safely and get it professionally installed, it wont be a problem at all. They'll let you know about the safety features like window switch, etc etc...so it cuts off your nitrous at a safe RPM and you wont accidently hit rev limit fuel cut with full blast nitrous and blow your engine.

Awesome, thanks everybody. It seems like it would cost more to go for a custom S/C or T/C than to go Kleeman. So, N2O sounds like the way to go. I spoke with a couple of people and they were saying that 75 shot would probably be perfect, maybe I could take a 100 shot.
What kind of hp and tq gains would I see with a 75 shot of nitrous? And, because I am nitrous illiterate, what is the actual difference between different shots, like 50 shot and 75 shot? Do those numbers represent hp or the amount of nitrous that will be pumped through the motor?

Generally a 50 shot gives you around 50hp, 75 shot 75hp, and etc... at least thats the rule of thumb. Bigger shots put in more nitrous, and hence you get more power. Here's a usefu, easy to read, link for people that are new to nitrous. http://paultan.org/archives/2006/02/...us-oxide-work/
As long as you get all of the safety equipment, I'm pretty sure you won't have a problem. Its always better to go overkill with safety equipment, then to not have enough. Like I said before, since not many people (if any) are running nitrous on these cars, I would start out with a small shot like a 50 shot first. Then if I see there are no problems and everything runs great, I would upgrade to a 75 shot, and may be 100 shot later.

Alright, thanks for the advice. Now, what do you guys think about price? I went to Auto Masters of Westchester and they quoted me at right around $3,000 for a totally installed nitrous setup. I really wish it was cheaper. Does anybody know any place in Westchester County, Bronx, or Manhattan, NY that does nitrous (safely) and for a good price?
Thanks.
I also spoke with Oliver from SpeedTuningUSA. He said it would be an extra $200 on top of the $300 for the ECU tuning if I wanted to have the ECU tuned for nitrous use.

Thanks bro, I will definitely check them out.

$3000 for, say, a 75 HP gain makes the laughing gas system a relatively cheap source of power. At $40 per extra horsepower it beats just about anything else one can do (ECU, headers, supercharger ...).
The M113 engine is very robust, so presumably it can handle a few "shots" with ease IF the system is engineered right to avoid detonation.

Did they tell you exactly what parts they're including? It might be a bit cheaper if you get all the parts yourself, and then just let them install it.
