What gives here? Are CLS550 fast or what? That ****en guy launched faster than my 2005 E55 AMG. Actually I lost traction for a second, then it launched. Seemed he had 0 traction loss. By then he has a good 1 1/2 cars on me. We stopped around 60 when traffic came. Am I missing something here or am I just a lousy launcher(which i think I am). Any tips on how to launch properly or was this fools cars just tuned.

It could have had the optional AWD, if it was a new model

Vanquish59

It was actually a 4matic. Would I have slowly caught up to it though?

HeissRod

Depends on the length of the race and how much of a head start he had, I guess.

That and he could have been tuned. Eurocharged claims 80hp/90tq with just a tune.

Vanquish59

Ridiculous launch though. I was impressed.

demetaktak

you woulda caught him. launching E55 can be kinda tricky, i know i had problems launching when i first bought it.
this is what i do to launch:
1. warm up slicks or semi slicks only, the colder the normal road tires, the better grip they have.
2. keep up the RPM to about 1.5-1.7 and then only take your left foot off the brake, dnt feed in the throttle.
3.as soon as you get the car rolling start feeding in the throttle, it should take you about 1-2s till full throttle.
this my technique with the launch and it proved to be most effective, but again, my care is 600+ hp. if yours is stock or with less power, you can be more aggressive in flooring it, but i suggest you keep the initial RPM as I do.

hope this helps

keep in mind that switching gears on your own is the best only when you know your peak porer RPM for which you d need a dyno graph.
/e55 is an awesome car to launch once you get the feel of it.

It took me a good 1.5 seconds to have strong traction, by then he easily had like 1.5 car lengths ahead of me and he was pulling very hard. Couldn't believe it. I was hoping that once I caught traction I would be closing the gap. Looked it up they have about 400hp with like 420 torque or something, almost like an M3.

Vanquish59

My car is completely stock. Any mods you recommend for a daily driver that just wants a fast car? Also, any problems with your mods and who did it?

demetaktak

ye and they heavy too. if i floor it from dead stop within 2/3 meters i hit second gear and keep spinning all the way to 130 kph. which is very slow. i know the car is just asking you to floor it but the easier you take it the faster it will launch. now if you racing from about 60 kph, then floor it like you stole it.

Vanquish59

Agreed, dead stop is hard. From like 35mph+ it's a good pull. Plus that CLS550 is 4matic.

demetaktak

i had runs with non stock subarus and they didnt pull the whole car length when i had a good launch.. also tire pressure makes a huge difference... i keep mine @ 3 bar for highway racing and 1.3 bar for dead stop launches.

demetaktak

as to what goes for mods, its so many ways you can go, but you must not forget the importance of cooling.
my car with just a tune gave me a whopping 465 whp/ 585 bhp which is nowhere near normal. now i have installed custom upper pulley, giving me 0.15 more boost. also took out the cats and the resonator. this gave me above 600 bhp. i m planning on splitting the cooling for engine and supercharger separately and installing larger throttle body. stock is 74.5mm - getting 82mm S class throttle body. also, methanol helps to cool your engine and keep it safe at the same time. headers is one of the bets bets you got, but its costly.good ones cost above 2 grand. i dnt live in the US so i cant tell you the shop, but headers i know you should go for kleemann. my s/c pulley is a copy of the one eurocharger makes. i m doing everything through friends and custom crafting.

Vanquish59

Nice man. I actually just went and did like 20 runs of the strategy you mentioned for launching and I must say it's pretty rock solid. I would say I don't get 100% traction, but easily 80%.

My main goal is a eurocharged performance upgrade but I'm very skeptical because I have a warranty on the car and I can't risk the pieces of **** finding out that I'm modded.

So what I wanted to just do is a eurocharged tune for now. They told me "The power gains are 40-45whp". Some questions...Do I need cooling for the tune alone? Would there ever be a possibility of engine malfunctioning or just engine meltdown with a tune from eurocharged. Also, is the tune detectable..

demetaktak

ok. look if you get 100% traction means you are not flooring it enough. wheels should spin, but not in one place, you should be accelerating while spinning.
the tune supposedly gives a bump from 469 bhp to 512 bhp on average, mine was a unbelievable exception to bump to 585. u dont need a cooling upgrade for just a tune. but its always a good thing. even with the pulley, the stock intercooler does the job. eurocharger will give ou max of 0.9 bar (s/c pulley). if you go for the crank pulley also, going up to 1-1.3 bar, then definitely you will need both cooling and header upgrade. u can always split your cooling, separate for the charger, separate for the engine.

this is what i have:
78mm supercharger pulley + tune
aftermarket k&n sport filters
removed cat converters and resonator
moved the headlight washers to spray the intercooler on demand.

this gave me above 600 bhp, when in idea it should have given me under 600. every car is different...

for now i have a low budget plan for the following upgrades:
1. 82 mm throttle body (used from S500)
2. removing the small headlights (high beams) for better airflow through aluminum piping straight to the throttle body.
3. splitting the cooling
maybe:
methanol kit
tampering with the gasoline octane (103-105) and getting a tune for that octane. ideally, this should be no more than 200-300 usd.

over the winter i think i will be able to:
1. larger intercooler
2. headers (making them myself off kleemann)
3. 182 crank pulley
4. TCU tune!!!

this should safely boost me to 1.3 bar and give me about 750 bhp which is 625 whp and 1000-1200NM
but this is all in theory, it may as well not work out...

Stock CLS550 is 4.6s to 60MPH. Any slip and the E55 is at 4.5-5s. We have more torque, so expect more trouble trying to get off the line. Rolling starts at 4,000RPM is where my car will shred most.

HeissRod

Are you saying cold street tires are good? I don't believe that.

dchl21

wow .. bro way to represent

2000UZJ

I rarely spin in sub-zero tempuratures. It's only when the tires are hot and hard. Cold and sticky tires are the way to go

HeissRod

Are you sure you know the properties of rubber?

Denroll

Does your car feel "slow"? Has your intercooler pump been changed? That can really kill power if the pump is going out.

If you have a tune, it will be undetectable. Car will drive better and have more power.

E55Freak

I think he's being sarcastic

G_Money

Hah! Like an the original Evo VIIIs! Have you been able to tell a difference with this mod?

Pufftrees

Tuned 550 bi-turbos are freaking nasty

AKnight55

With a tune the bi turbo 550s are around 500 hp. No joke.

HeissRod

Damn internet. When will they code it to be able to convey sarcasm?!
