nos bahahaa, wait till your engine goes kaboom!
LEAVE IT STOCK!!! and enjoy it
its like an italian that buys a fiat, we all say FIX IT AGAIN TONY!

 

ouch

 

wow... i would of thought him to be the fastest mercedes in the world from all those crazy mods he put up, i heard he made 100 whp with cams ?

 

LMAO! ill change your motor when its knocking lol

 

ok baby boy.. you will change my motor when its knocking? do u even know how to use a wrench ? knock urself in the head b4 u knock people u dont know.. dumb ***...

 

i wasnt asking for ur opinion on blowing up a motor u lop lol im asking a question to the guys that use nitrous stupid entry level hater..

 

What's up jack pro, how are you doing ?
This is how an urban legend starts . A 200+ plus shot would empty the fuel rail in a hurry. You would need a seperate fuel system just for the Nitrous, not to mention some race gas. The Biggest shot I ran is 125 , If my memory serves me right 51-53 & 23-21 pills. The only damage I ever did was to the blower, it sucked up the inlet hose wire on boost. So everyone better check those things and tie them with safety wire, especially the big tb guys.

The guys who are modding these cars now defintely have an advantage with all the different aftermarket go fast goodies available for the 55's and MB's in general.

 

dope thanks r flow! im gonna start on 50 and work up to a 100 shot on the dyno

 

How are you rflow306? you know you can call someone once in a while Nice seeing you post in such a long time. You are for sure one of the Legend on the board.

 

+1 Here, here.

 

On the ZEX system, is it automatically triggered when you hit WOT when system is armed? If so how do you prevent activation at low rpm... do you manually use the arm button for this, or is this wired into the rpm read from the cars data output?

 

Running sauce is like having a hand grenade with a loose pin in your engine. Hope y'all have large differed maintenance bank accounts. I'm waiting for the first slew of used BiTurbo E63's to show up. (nothing is faster than the depreciation of an AMG Benz). Porsche gives you 600 HP from a 3.6L production motor (167hp/ltr). Theoretically a 5.5L motor at, lets say 150HP/ltr gets you 825HP. Is 1K possible?

 

You can program it to activate however you like, Via a button or wot.

 

I have been toying with the idea of running a dry 35 shot for cooling purposes only. Nothing like injecting -100 degree air into the TB to cool things down right quick!

 

And youll still get HP with the cooling too, WIN/WIN

 

i thought about the 35 dry shot too -- either that or 50 shot of wet... extra security in case my ECU cant compensate for the the 35 shot.

Please let me know if you run the 35shot -- i am very interested in the car's reaction... My car is not modded as aggressively - So, if your ECU can read the shot correctly and compensate with the right amount of fuel --- then mine will surely have no problem.

 

Some of the high end kits actually add fuel based on data logging, such as on high end Zex Kits, this is from their website. ill post the one for dry management when i find it.


Wet nitrous oxide systems provide fuel enrichment by teeing off of the engine fuel rail and feeding it into the injection nozzle.

The ZEX™ "Wet" Nitrous Oxide System has the most advance features of any "wet" nitrous oxide system on the market. All components, such as the solenoids and activation electronics, are factory pre-assembled inside the "Nitrous Management Unit". This ensures you will be spending less time in the garage installing the system and more time out having fun. The patent pending "Fuel Shear" technology used in the ZEX™ nitrous nozzle, places the enrichment fuel directly inside the high-speed nitrous oxide plume exiting the nozzle. This results in the most complete atomization of enrichment fuel possible. Super-fine atomization of enrichment fuel ensures maximum horsepower and eliminates fuel puddling that can cause intake backfires. Even the way the ZEX™ Nitrous System is activated is unique. Instead of relying on crude micro-switches or push buttons, the ZEX™ "wet" nitrous system uses advanced electronics to "learn" the throttle position sensor (TPS) voltage curve. It then programs itself for your specific vehicle and, when armed, will only activate the nitrous system at wide-open throttle. This ensures perfect engagement every time the nitrous system is used. Advanced features like this make the ZEX™ "wet" nitrous system the easiest to install, the most powerful, and the most reliable nitrous system on the market.


Found it:

Dry nitrous oxide systems provide fuel enrichment by increasing the fuel pressure to the fuel injectors as the nitrous system activates.

ZEX™ has designed the ultimate "Smart" Nitrous Oxide System. The ZEX™ "Dry" Nitrous System, using ZEX™'s patented fuel control technology, reads the nitrous bottle pressure and adjusts the fuel enrichment accordingly. If it is a cool day out and the nitrous bottle pressure is around 700 psi range, the nitrous system will add less enrichment than if it is a warm day and the nitrous bottle is at 950 psi. This unique feature ensures that you always have the optimum ratio of nitrous oxide and fuel, never too rich, never too lean. This ensures maximum power and safety at all bottle pressures. Once armed, the kit is activated at wide-open throttle by a programmable electronic sensor that "learns" the voltage curve of your TPS sensor. This design ensures your nitrous oxide is engaged at the perfect throttle point every time. The design of ZEX™ "Dry" Nitrous System makes it the simplest, safest, and easiest to install nitrous oxide kit on the market.

If your doing a dry shot do you place the spray nozzles before or after the filters on the airbox?

 

I would tap it in right before the TB where the two rubber hoses merge.

 

A friend has an E55 with 180 pulley and tune which it was running perfect. after one year he decided to install a Zex wet 100 shot, on the second run the engine blew, the AFR was low 11. A piston and cylinder wall melted. if only one cylinder was running lean you cannot see it from a wideband cause you are watching the 4 pistons on one side. be careful guys, the E55 engine is weak.

 

The nitrous just brought out an already common problem for your friend's E55 owners with lean cyclinders. Honestly I think a proper wet kit should've fixed the problem. I think a dozen or more have had a melted piston without using nitrous.

 

Not only that would help, But also get a better pump/fuel rail like TTMs just to be on the safe side.. investments like these usually pay off

 

I had a WET FOGGER NOS set up on my 4cyl turbocharged engine, 50hp jets (actual difference on the dyno was 80hp). I went through 14 bottles of juice and never had a single problem.

I believe when set up properly and used in small quantities it is perfectly fine, however, it is still a big risk, especially when you strapping it on these expensive/hard to replace engines, this is the reason I have managed to stay clear, so far. lol
