Ok so there is all this hype about E55 vs E63, there 1/4 times in comparison, and how simple mods can/may be.

I want to know if anyone has put Nitrous on their 63 yet. As the 55 with lower compression loves the boost, the 63 with high compression would love the juice. This is my next mod on my E63 for sure, but first I want to brain storm with those who have had, or know someone who has had, some experience with spray on AMG's.

Whats preferred with these cars? Wet or dry kits? Can the electronics pick up the nitrous of a dry kit? With two intake runners are the options limited to wet only, manifold injection?

I think its hard to compare the two cars performances being one is boosted, but from personal experience, I have beaten the two 55's I have raced. I was looking into getting a 55 but something about this new engine got me going. This is as close to a luxury, high compression big block as I can get. With a nitrous background, i will say that this car is plenty fast, but if you start pulling me in ur 55, I might just have a stage(or two) to show you who's boss when needed...

chiromikey

get that kit figured out by nov. 3rd and head over here to speedworld raceway in phoenix. there will be plenty of amg's (among many other exotics) to play with and i'd love to see a 63 in the 11's!!!

I also think Nitrous would be a great solution... I have the same questions, but I'm not greedy, 75 hp would be perfect and I don't think it would blow anything up if done with all of the proper controls (controls to prevent injection at part throttle, below a certain RPM, above a certain RPM, etc). I'd love to hear from anyone who has done it.

Zax63

but I'm still thinking a shorter rear gear ratio out of an e500 7spd (with tranny programming as well) will fix most E63 problems and probably not void warranty and get really low 12's - Vadim is working on this - hurry up, Vadim!

What is the E63's compression ratio? From my research... the best option is a wet shot with a window swicth that will only activate the nitrous at WOT and if its above certain rpm's. A dry kit "should" work if you keep it small. I.e. 50 shot or less. There are a number of E55's on this board already running nitrous and they have a wealth of knowledge on the subject. Hopefully they chime in.

rflow306

It has a Maf sensor so a dry kit would work perfect. The 63 should be able to take 100 shot with-out a problem. The new M's are at 150+ dry with just some timing retard.

e63boy07

i wouldnt go with nitrous

ErikGreen

I understand that it has a MAF sensor, however Fords MAF won't pick up the nitrous like the Chevys does. This is why I ask for someones opinion who has dealt with dry kits. So if rflow306 has definite knowledge of the AMG electronics working the same way chevy's do, please tell me bro

Question - are the engine electronics(MAF, timing, etc) on the 63 the same as its older 55? If so the opinion/experience of a 55 owner who has had a dry kit would be great. I would much rather run a dry kit due to its simplicity. Chevy's can pick up a 150hp shot like it was made to read nitrous. Those LS1 camaro's are so easy to make fast. Wet kits will ALWAYS be better/safer, however they require a ton of attention/plumbing.

Nitrous should ONLY be operated at WOT. The best way to perform this on our "hidden" TB's is to mount the switch under the dash where the pedal itself will contact the switch under WOT. Add's to less/shorter wiring too. I have used TB switches before and they are in no means as accurate as a mechanical switch. My main problem is with letting off the throttle. The delay has left unspent nitrous and fuel in the intake. You can only imagine what has happened the next time you burp the throttle...POOF! This was done on a 98 cobra with a wet kit and it would continuely blow all vacuume lines off. That is until I switched back to a mechanical switch.

Being that I will be playing with a 6 figure car, I don't want a single mistake.

Please share your experiences...

chiromikey-

I will def be in the 11's after this and considering my birthday is in Nov. I want this done asap. My goal is 11.5, which is easily attainable. Even with this heavy *** sled

E55 RUSS

I want to get some JUICE for my E55...How can help ME out here ??? RFLOW ???

I am getting front IC mod and during the winter want to get NOS set up which would be safe to use once or twice a week

Who builds best NOS systems in the world ???

ErikGreen

Best? Thats always a matter of opinion.
IMO, www.nitrousexpress.com makes the best systems. But I'm an old schooler when it comes to nitrous. Some new/small companies have specific kits for cars that blow big companies like NX out of the water. They come with awesome electronics designed to be the safest operation for your designated vehicle.

But chemical injection is all the same, if you know how the cars electronics(FI cars) are going to react. Understanding this basic knowledge can save you thousands when buying nitrous systems.

I carbureted cars, nitrous is EASY fun

I had nitrous on my CLK500. It was a 75 wet shot, the whole kit was basically from NOS (nitrous oxide systems). No problems, easy to use. I just took it to a local tuner shop, told them like Paul Walker "I need NOS" and they hooked me up. All lines were hidden, solenoid was completely covered. I had the arm switch placed under the dash, where your legs are. When I flipped it and armed it, it also switched my steering wheel horn into the actual button.

I liked the 75 shot a lot, was gonna go for a 100 shot but I was starting to spend lots of money on other things and after I took the whole kit out to get my car serviced, I never had the desire to put it back in again (basically I'm just waiting till I get my next car).

I don't think you could go wrong with a wet shot. 75 should definitely be fine on your engine. Dry shot? Idk, my MAF sensor went on me just because my air filters were different. I'm sure a 75+ shot of N2O would do the same thing...but as far as if it will add the right amount of fuel to it and all, I don't know. Wet shot is safest, I don't think anybody's even installed any type of nitrous kit, let alone a dry kit, on a 63. You'd be the guinnea pig. Thats why you might be better off with wet.

Good luck and keep us updated. Your car is gonna be fast bro

Vadim @ FD

Dual dry 50HP shots through each MAF might work.

More research will be needed.

If it does work out, that could be the easiest install.

StealthAuto

I agree with Vadim. A dry 50-shot is your safest bet and will not require tuning.

Let us know how everything turns out

rflow306

I can't speak for the mass air on the e63 but the one the m5's and m6's respond instantly to the nitrous. It could be very easy to check on an e63 start with two small jets at low bottle pressure, then raise the bottle pressure and see how quickly the afr's change.

If I owned one it would have had nitrous on it a long time ago with some 11 second time slips for Juice to correct.

ErikGreen

After I logged off I was thinking this same thing. I would need a T/Y splitter with even length lines(considering the speed at which the gas travels it may not be necessary) so both would pick up the condition. But again I agree with more research is why I started this thread.

Could testing of a restricted MAF prove that the computer can still compensate?
Can Mercedes MAF even pick up this condition? If so, is both really necessary?
What is the fuel pump rated at(lph)? Being an NA car, I'm sure if they used the same pump as the FI 55's it should be plenty good to handle 600hp. What about 650hp?
Are the fuel lines/injectors large enough to support that power?


If the motor fails, I guess as easy as it was to install a dry kit, it could be removed and the warranty can start me back off on the drawing board with a clean slate.
However, who knows a way I can obtain more information on the MAF sensors used on these cars? I can do a direct comparison to the M series or even the chevy's design. Please help me figure out my quest for 600-650 bhp

Zod

I love that quote!

ErikGreen

Can anyone supply me with pics of an M5/M6 MAF sensor. Preferably the inside of one. I want to compare to my AMG style.

Also, if anyone knows of a AMG tech that can give more information on how our MAF's work, I would love to talk to him/her

ScottCLS55

Old thread I know.. Sorry.

I'm thinking of doing a dry setup. I have a nx express wetkit I bought, but it seems others are using the dry kit with luck.

Will it be ok to run just the nitrous solenoid with a .25 jet and split it with a y and plumb 2 dry nozzles at the bottom of the air filter boxes before the maf sensors?

guysandiego

we should get together --- then you can race some non-stock E55's -- my buddy has a gold one in blue diamond area - he will kill your car -- I am NW I am a tad slower than my pal

guysandiego

we were also thinking about adding NOS to our cars -- so, we can have lots of fun together.

Benz-O-Rama

I think JRcart has run nitrous on his CLK63 BS. Might want to PM him and ask about his experience before trying.

MB_Forever

+1

Also, RARfinancial has a nitrous kit on his CLS63 and of course the C63 king: DadsC63. All 3 members are active on the boards, you can PM them for more information or even better, get them post here

ScottCLS55

I've been pm'ing Jim a little. I've found the info I need I think. Its hard to hide on the stock air box for best results.
My set up will be a single No2 solenoid split with 2 spray nozzles in the front of each airbox above the filter.
I will start with the smallest jet I have and work up to a 22-25 jet.

Guysandiego- I think you are on the wrong thread or drugs. not sure yet?

guysandiego

maybe its the wrong thread -- but this info could be helpful for NOS-ing an E55 -- Just in case I need to race a modded TT P-car. Never raced an E63 they are never game.

Someone stated that 50 shot dry is pretty safe -- the ECU can compensate? -- Do you think this can work on an E55? or is it best to do a wetshot? I was thinking of doing a small shot 50-75 ---

Another note - I read a few times that the E63 tranny is great but not strong like the E55 which handles upwards to 700hp -- So, maybe 100shot of NOS on an E63 will be engine safe but not trannie.

ScottCLS55

.28-.3 are around 100hp

Im going to .23-.25 jet size probably around 75hp. If Rarfinancial hasn't blown his tranny going 11's yet I doubt I will blow mine at 12.1.
