"laughing Gas" aka: Nitrous Oxide
I came across a universal Wet type Nitrous Oxide System in a buddies garage, he is looking to sell it, its a set up for 4-6 cylinder single nozzle 35-100hp shot, all complete never installed......
has anybody used nitrous on a 103 engine? if so what kind of performance did you see? |

Nitrous systems correspond to their given shot numbers (jet size is very important) as long as your fuel mixture is correct. Continuous injection systems, like yours, need a supplementary fuel supply in order to fill the needs of any amount of nitrous to avoid burning up your engine. Make sure you run a wet system and not a dry one. You can use a dry system only if you have a computer running an auxiliary injector (the ideal option) to keep the mixture in check. I'm sure you can run a 100 shot nitrous system on a stock M103 without breaking anything. Look at the condition of your engine first before throwing too much nitrous in it.

Oh, you should also use a RPM switch in order to cut your shot for shifts and especially mixture, your redline kills your fuel pump.

I tried it on my '99 CLK 320. It's jetted for about 100hp. I like it, but there are a few drawbacks: Varying bottle pressure is a drag to deal with. Bottles run out faster than I expected and are expensive and time consuming to fill. You need to purge before you use it (purging and leakage is probably where ½ my juice goes). The computer will often refuse to shift into second while the juice is on.
Pluses are: I can smoke all my friends rides. People always talk about how the power increase is day and night and their rides are super fast now etc. I figured with a my light car (3200lbs) and a 100 shot I’d be pretty happy, but in the back of my mind I knew that 315hp isn’t all that much. It is a nice increase, but it’s no hot rod. I think it’s about as quick as the 500 or 55AMG. I have G-Tech accelerometer, I’ve only had a few chances to use it, but it’s about 5.3 seconds 0-60 with the nitrous, 6.0 without. |
