How would a stock E55 do against a 2011+ tuned E550 and tuned BMW 550i from a 60-150 roll?

 

destroy them

 

I think you mean 2012+ E550, right? The TT version is what im guessing you meant.. Well I saw one dyno of a 2012 cls550 and it dynoed at 490 wrhp and over 500 rwtq, so I think it would be a pretty close race.. One member with a new 550 and Renntech tune ran 12.5 in the 1/4 mile, so it wouldnt destroy it I dont think..

 

What ?! 2012 CLS550 makes 402 hp and 443 lbs/feet. Going on the dyno without any mods automatically increased it's power ?

 

This cls550 had a Renntech tune sorry..

 

and with 490 it only ran 12.5? How much does that sucker weigh?

 

Two different cars..

Cls550 with Renntech tune



A E550 with a Renntech tune ran 12.5, but I havent seen the time slip yet or dyno graph

 

OOOHHHHHHHH...it's my reading comprehension....ya know?

 

it's listed at 402 HP, in actuality it makes ~440.

 

Non TT E550, the E55 will kill it. a 2012 TT? good guess

 

I recently raced a E Coupe with the 4.4L twin turbo and it kept up with me right up until 110+.
Then i started pulling away from it

 

Not sure how many stock E55's there are out there but if a TT550 owner in SoCal wants to run a mod'd E55.....

 

I got into it with a new E63, it is Fast off the line, (launch control, I beleive), he got got a few car length's on me and at about the 1/8 mile point I started reeling him in, shut it down at around 1/4 point and he was up by maybe 5ft.. I would have taken him and he knew it..

 

All he would need to do is call up Renntech and get a tune and he would be making over 600 at the wheels..

 

Was the E coupe tuned?

Are you stock or modded?

 

What did it trap?

It's in STD numbers, which is about 380rwhp SAE before tune and 474rwhp SAE after tune

 

I hadn't seen any making over 600 at the wheels with a tune alone?

 

I dunno if it was tuned.
Im a stage II EC car but i had two passengers, the E Coupe was a 100lb girl or some prince looking type thing. Whatever it was was driving like a jackass and was not afraid to take me on. Three pulls i came out ahead every time.

 

Well and filters..Here it is copied directly from the article (which I can not post)

2012 E63 Renntech Tune...607whp/710wtq!!!
So last week I sent my ECU out to Renntech to have it tuned. Everything went very smoothly, and I received it back two days later as planned, along with a couple of BMC Air Filters. Like a kid on Christmas morning, I opened the box and installed the goodies right away. Then I took the car for a spin.

Now, mind you, I've read all the reviews and power results on these M157 tunes, but never in my wildest dreams did I imagine it would have the effect it did. The car felt strong before, but now it feels AMAZING! Stock-like driveability at partial throttle, but at WOT, all hell breaks loose. Mashing the throttle on the freeway at speed even spins the tires loose. This thing is a monster!

To make sure the results I felt on the street could be verified on the dyno, I took the car down to MD Automotive in Westminster to check the power output. Keep in mind this is the same shop used in all the Edmunds.com dyno reviews. It's a typical, run-of-the-mill Dynojet 248, and Mark the owner is a really nice guy.

Car: 2012 E63 AMG Non-PP
Modifications: BMC Air Filters, Renntech Tune
Fuel: 95 octane mix via blend of Chevron 91 and VP Racing 100
Ambient Conditions: 75 deg F, 28.79 Baro, 59% Humidity
Dyno Type: Dynojet 248
Peak Results (4th gear): 607whp & 710wtq SAE Corrected!!!

Attached below is a picture of the dyno graph printout. Besides amazing peak power, note how smooth the curves are, and how safe the AFR looks.

Needless the say, I couldn't be happier with these results. Much thanks to George and team at Renntech for the great customer service and a top-notch product.

Next up...the Airstrip Attack event hosted by Shift-S3ctor Nov 10-11. I think this car is really going to surprise some people there. Can't wait!

 

Last weekend I ran a CLS 550 from about 70+ and killed it. I am stock with an ECU/TCU tune. It sure looked sweet though!

 

Damn! Those numbers are crazy... looks like I know what I'm getting in a few years when I'm done beating on this M.

 

I am positive the one I ran was stock.. Beleive me I know a modded TT will run away.. They are Real fast stock.. That's why in a few years I'm thinking CLS63 all the way..

 

I believe that, the problem is it's not just a regular tuned car. They're running race gas! I'm sure they can bolt on a 100hp shot and make well over 700hp Also, I've recently met several people with Renntech tuned biturbos and all of them were right around 560-570 at the wheels and that was wit filters.
