hmmmm, it will be fast but 9's???

He could capture the record but running 9s aint happening

V12Godspeed

Thanks Sun!!

Thanks Jim! We will find out within the next week or so. Keep fingers crossed. Speedriven is on the map....I can't stop saying how talented Marcin is.

Thanks. I can't really pin point yet...but I am after a lot. What ever gets me into the 9's.

Thanks.

Thanks. 2 weeks will look like an eternity. I have waited nearly 8 Months. what's another 2 weeks.

I told you, you might as well do it. Time and Patience are key.


Thanks Steve. 9's is a very ambitious target we have set but with the upgraded turbos and some nice slicks, either it breaks or it makes it. We shall find out by september.

You want to put some gravy on that?...$$$ j/k..
If it doesnt happen I will be very dissapointed, but the sole reason I made this project was with the intention of running 9s all day. If I wanted 10's I would have gotten the regular bolt on's and kept the 55 motor.

I am a firm believer in saying you havent run an ET until you run that ET, therefore I wont make any predictions.

Thericker

W/upgraded turbos & supporting mods it'll be laying down 750 rwhp, coupled w/4300 lb odd race weight should be interesting

tgoss

Looks fresh man! Best of luck pulling the rest of her together

juicee63

Wow Jody you are NUTZ!!

I Love it.

Whilst I have no doubt this will be fast as heck,
I do not , or at least have never seen a modern MB defeat the throttle by wire, the tq limitations in the TCU..

It will take a ton of work to run your car into the 9's , even 1000 hp wont matter. How do you get out of the box with 750hp, your going to need alot of help. look at Ahmad, his car is much much lighter, his launch is hard as they come and yer talking bout waxing him by a half second? Beating Alan by 7/10ths? Taking out Seldon by 1/2 second, his car certainly had some serious hp.. I suppose with a perfect run in very low DA, you could go 10.20

V12Godspeed

I agree, thats why I dont want to spit up and it fall on my face, LOL..

take this in perspective, my weighted in roguhly 4700 lbs and when it ran it was not the "final" tune, it was the first developed tune by VRP and Marcin at that time. It was considered a fat tune (safe). With the new improvements and developments they have made it is possible to take a whack at it.

The E is much lighter and will have some good power. For now let's just make her run first, then we will see what happens with power delivery.

bassn_07

Exactly! Get the car running good and healthy then worry about breaking records. There's no doubt your beast will be giving some of us a smack down but I'm sure you'll run into a few weak links along the way. I also wonder what the weight distribution factor will do to the car with the heavier engine up front....possibly traction issues?

Either way Jody that cars going to be a fricken beast!!! Good luck and I'll check back in a couple of weeks.

V12Godspeed

Absolutely. Not too worried about the weight distribution as Barbus stuff a V12 in the C class and it is even more lighter than the E. Should be a few pounds heavier in the front but no biggie. My most fearful factor is breaking axle and breaking the differential. We shall see.

TMC M5

Just out of curiosity, has Marcin compared the rear differential and driveline in the E55 to a 65's? I was wondering if there was any noticeable difference between them. You read the AMG literature and they talk about how they beefed things up....just wondering what the actual difference is between the 55K and V12 Biturbo driveline.

As you said, the limiting factor is going to be the launch. I think having additional weight up front isn't going to help the weight transfer to the rear. You shouldn't compare a Brabus set-up with what you are trying to accomplish. They only care about Autobahn acceleration... you are trying to optimize a drag strip launch...two completely different things.

I think if you can get down below a 6.5s 1/8 mile time....and trap a 140+mph... a 9.99s ET is definitely possible. Good luck!

Tom

V12Godspeed

Thanks Tom, I forgot you are the literature guru (Brabus) . They have something called Anti-dive Geometry axles and Anti Squat- Axles...what ever that means. LOL.

You bring up a good point on the rear differential. I believe I spoke to Marcin about this and we could not determine if the driveline was indeed the same. We will have to do some research on this and get back with updates. I would think the 600 would share similar parts with the 55's. in terms of the 65 that is a different game, If I do brake something I would not mind trying the 65 parts.

Sunir

9's may be tough but not impossible (especially with Marcin working on your car) not due to hp or tq but due to traction. I discussed this w/ Marcin myself...he says if you look at the 55 and 65, even though the 65 has more tq and even if we are talking around the same levels of hp (now I'm assuming modded cars here - to the level of bolt ons and tune) ...at the end of the day we're talking 10's for both cars and around the same levels of 10's...now on the highway different story the 65 will have legs up top. The thing with the drag strip is just that the launch and getting the car to really work good for that initial peak acceleration. The SC on the 55 does that well and although the v12TT will have more power/tq it's more than likely not going to get the kind of traction it needs...it takes a lot to harness the power and tq it makes. Marcin calls it "usable" power and torque which is most important in drag racing. Every time I talk to that guy I learn new things

Thericker

These may help change that traction prob, up until now every other 65/600 has run dwn the 1320' w/18" Drag setups...

These are 16" 255/50 (65's can ONLY run 18" whls due to having the largest rear rotors, but the 55/600 share same rotor sizing & enables 16" setups)

Custom RED lettering by me...

V12Godspeed

Please send me the recipe. Nice set up.

V12Godspeed

+1 Agree with you Sunir. At this point I just want the thing to turn the key. After that I will start going to the strip and testing the waters to see where the limit lies. Thanks.

Marcin is indeed very talented, Speedriven is accomplishing great things.

beauphus

mine are on the way to Edison as we speak

Sunir

Ricker...the 16" hoosier drag radials (255's) or same size Mickey T's will of course help with mechanical grip or traction. However there will still be slip, even with stickies...the v12tt has to translate a lot of power and tq so it's "effective usage" even with drag radials is not greater than a 55's. In other words there is a limit to the amount of load that can be translated to grip, anything above that is irrelevent...given the setup and the inherent constriant of the chassis. Marcin and I discussed this and are in agreement in terms of both theory and practicality models.

One of the real problems with these cars are the rear suspension and geometry thereof. Wheel hop/axle wrap is an issue, also camber gain. the independent rear suspension as a whole is not conductive to hard launches.

Now lets say you had a modded v12tt, what you would really need to harness that power/tq is a 4 link rear suspension with adjustable hiem joint ends with a solid axle housing a locker or a spool. Furthermore if you had the rears tubbed with real 13" drag slicks...then you could harness the true potential of the v12tt

The mercedes street car rear suspension and chassis dynamics are the weakest link when it comes to drag racing these cars. MB made the cars for high speed driving which they do very well. Because these cars make so much power and torque does not mean that we can harness all of it in a drag race situation (and this is without traction aid like Launch control), in fact the usable levels of power/tq that can be translated across the board are similar, because the similarity in rear suspension dynamics set forth the limits of usability.

^^^ All I need is a 1.6 60 footer to get me close. take a look at the launch on my Sig, while it was not performed by me but a veteran driver, it is doable in private track rentals and an excellent track prep.

In that video it cut a 1.5 60 footer....the thing hooked like there is no tomorrow. From my understanding the 55's have a better drag set up than the CL. It squats better and the weight transfer should be even better. No ABC suspension here but Airmatic. The car ran 265-40's MT,s you could literally hear the tires sticking to the VHT ...did I say the car was putting north of 900 rwtq...Seems to have harnessed the torque pretty well to me.

This conversation could go on and on...once the car is on...the next day it's going to a strip. We will find out....Like Leonidas said "Immortals??...we put their name to the test' ...

TMC M5

What's the matter...you forgot Jay's name???

Tom

V12Godspeed

Not at all. Just didnt see the need since half the world knows he performed the run.

OUTCAST

Your project is moving right along, should be a killer car when done.

gonzales25

I see your from OK, I live in Lawton.

ZHOUND

Very nice project. If you've done any drag racing you know that going from 11s to 10s is a bit of work. But going from 10s to 9s is significantly more work in any car. I think ~750rwhp will not be enough for a 4000lb car to dabble into 9s.

Best of luck to you. Are there a lot of E55s in 10s right now? Sorry I'm new to the Benz scene.

chiromikey

only a few...but at least we now have a recipe.

MB_Forever

And I think soon, we may even see an E55 overtake the current Mercedes record of 10.5x

Sunir

sounds good...waiting is a hard ordeal. I think with the E chassis and v12TT once the bugs are worked out this car may have a shot to go 9's but it's still going to be a challenge due to the power needed to drop from 10's to 9's will be steep exponential. Plus the car is over 4000 lbs and the does not have the best aero characterisitics, and the issue of wheel hop/traction/and launch will be a factor. Best of luck Jody!
