Nitrous Kit for my C55
I have narrowed it down to EFI Wet kits from 75-150 shot capacity.
Here are the ones I'm considering.
ZEX-82065 Dual Stage, NX-20927-10, VENOM 735-n750-8, NOS 05131 and the Ny-Trex 11010.
I like the VENOM since it has a computer module that monitors and adjusts the fuel automatically and shuts off the nitrous when it goes lean.
Here is the link. http://www.jegs.com/i/Venom/735/N750-8/10002/-1
What do you guys think? I primarily looked at Summit Racing and Jegs site.


will brag about it, but otherwise, I'm happy to be in 3rd only 0.1 seconds behind the shop car. Had this car for close to 10 years and love every day of ownership.
I'm not sure how this will work with your custom tune, and if it will readily interface with the MB ECU? Also this will not work so well if your current fuel inj are maxed out with your current blower setup under boost. If you're already using a adj fuel press reg to make up for small inj under boost.... this prob won't work for you.
I would choose a diff kit:
* you want a wet system meaning it supplies NOS and fuel. The wet systems I've delt with had solenoids for nos and fuel that kicked on under NOS use.
* you want a window switch which will not allow activation of nos under 3-3.5K rpms..... the worst thing you can do (short of going lean on NOS), is to turn it on at idle.... let the nos pool in the intake mani / blower, backfire and blow the top of your motor off. It does happen that is why they make you use the switch to turn it on @ WOT above 3K rpm.
* you want a bottle heater to keep consisent pressure supply.
To do it right all of this extra stuff adds up to wires, solenoids, complexity.
You could prob get away with a simple system with say a 30-50 shot to use primarily for the purposes of cooling the intake charge...... and net some impressive gains with the blower. I'd def start small, and don't get greedy
I like your style SIR! Go big or go home .
I don't think fuel will be an issue since I am running on E55K injectors AND the Kleemann fuel kit with Boost-a-pump. It's just a matter of having Rich tune for it. The kits I'm looking at includes jets in increments of 25 alll the way from 50 to 150.

I honestly give you a lot of props for trying and admire your passion for your car. I'm just afraid that by installing nitrous could cause some negative results..
Best of luck to ya.
He told me without any disrespect to Mike that this car feels alot faster than Hooley's C55 that is back in his shop right now so I should be satisfied. I was considering throwing on a set of PTE cams but he just told me to leave it alone as the gains do not meet the cost-benefit analysis.
So off to the track I go after I install the lightweight hood, fenders and wheels. This project is FINITO! Time to look at my next project soon.

I am extremely confident that I'll get over 500rwhp on a Dynojet in cooler weather when I pick up the car next week. No CELs after several hundred miles of test driving by Rich and his techs. The car was pretty heat-soaked and still pulled 475rwhp/525rwtq on a DD Dyno in 110 heat. I know Hooley's highest documented dyno was 482rwhp/580rwtq which is still the record on the same Dyno but I don't know the weather conditions on that run.
Alumnar's Kleemann S8 only sold for $20K so the market does not value heavily modified C55s. I was beating some modified E55s before I upgraded the motor so this last round of mods should make it one of the fastest AMGs period after the lightweight parts are installed. I love this car and plan on keeping for a LONG time. My next project will be another car but not to replace this one.

You big-dogs were certainly my inspiration.... or should I say... I BLAME you all for my klee mod car sickness.
Off to work.. time to drive my klee=car the 30 miles to my job. I love it.
Just drive the car and enjoy it. Don't do anything else until you have 1 year of solid driving on that car. Just enjoy the car.

Also, not trying to stir the pot, but am genuinely curious - above it mentions "both record-holding C55's" - what record(s) are held by AMGSC's car?
Ultimately, it comes down to getting her to the track.

I told him to send that car on its way. I for sure have and want nothing to do with it.
