The most Powerful MB in the USA. Quest for a 9 second 1/4 mile
Update:
Eurocharged did a great job getting the car tuned and I finally had some time to take the car to the track. Unfortunatly the only track open right now is a crappy local 1/8 mile track but will work for initial testing purposes.
As you can see from this video I am having tractions issues due to the poor rack condition. I just put ET streets and a locker rearend in the car yesterday will be back @ the track in 11 days to continue testing. This run was done with 16.0psi for the first 3.85 seconds then ramped up to 18.0 at the last 330' (93 octane). I have another 200 rwhp when I turn the car to 22psi on 100 octane. The trap speed is there and the car pulls very hard once I get traction. The 60' time was a horrible 2.02. If I can get to a sticky track and pull a 1.60 short time I will be able to pull off a 10.4X @ 138 mph on pump gas and a sub 9.5 @ 148ish. Right now only 4 cars on dragtimes have a higher 1/8mile mph than I currently do with low boost and pump gas. The next time out at the track I should best all but one of those cars.
I just placed an order for Chromoly tubing to fab a roll cage in the next 45 days or so as I will get kicked off the track without it very soon.

Here is one of the dyno sheets that I have. I do not remember what setting this was on but it kept maxing the dyno out so we had to roll into the boost so that the torque stayed below 1000ft lbs. The car makes every bit of 1150-1250ftlbs to the tires on a mustang dyno. BTW all of the runs made were hot runs, no ice whatsoever.
I am sure the car will make 1000rwhp on a dynojet pull iced down @ 22psi race fuel.

Interesting... 104+ mph in 1/8 mile is kooking sir.. Though upon studying that Dyno sheet IDK where you're expecting to get 1250 rwtq
or a legit 860+ rwhp... That trap speed isn't anywhere near that type of rwhp/rwtq
Based on your Trap, it is making around 750-800 Crank HP not 860+ rwhp
nonetheless impressive 1 off kit you've made
Forget the Dyno #'s as they can be skewed every which way, your Track #'s show The Real Deal, & 104 + mph in 1/8 th is NO joke but very far from TRUE 860 rwhp let alone 1250 rwtq...
This CL65 is making a TRUE 708 rwhp & only 812 rwtq on DynoJet obviously set correctly, He's quite a bit faster @ 109 mph in the 1/8 th mile...
http://www.dragtimes.com/2006-Merced...phs-20351.html
Spinning really bad like your 2.0x+ 60' claim doesn't mean you'll Trap higher w/Great 60' of 1.6x-1.5x as you must know lower 60' = much Lower ET but lower Trap speed too, the spinning actually nets a higher Trap in MOST cases.
Case in point check Marko's CL65 from boards here, matching your 1/8 mile @ 104 + yet he ONLY makes 692 rwhp chk out link & see how his ET's go down considerably w/other records, but so do his Trap speeds..
http://www.dragtimes.com/Mercedes-Be...lip-16853.html
PS the MB 9 sec Record has already been set in a pricey modded to hell SLR ET @ 9.7x if memory serves a lot lighter than our heavy V12's too.. As extra rwp/rwt get added to your CL (in your corner here, I love the V12 biturbo platform etc) it's not a linear curve in 1/4 mile ET progress a huge amount of variables to be overcome to get you into 9 seconds let alone 9.5x @ 148'ish as you state... I see you have a nice Track setup including Skinny's up front Skinny's alone can add 1-2 mph in Trap speeds..

Thericker, I think you skimmed over the part where this run was on low boost with 93 octane. I didn't mention that this was the fifth run wth the intercoolers quite warm. This is just about the lowest power setting I have with the car. I have at least another 200rwhp on tap with 100 octane, more boost and iced down intercoolers. The only thing that will keep this car from running the numbers I quoted is the tranny.
Right now there are only 4 cars on drag times that have trapped a higher MPH. I am confident that I will reduce that to two cars with my low boost pump gas tune the next time I am at the track. You are correct that most of the time a lower 60ft will reduce trap speed, but I am running 1/2 throttle the first 250' or so to keep the tires from spinning. All of the runs before netted a 101-102mph without part throttling the car down the track.
you said it and I am a staunch believer that the proof is in real life 1/4 mile times and I will provide those not a perfect scenario iced down inflated dyno jet sheet. I have a stack of 1000/1000 dyno sheets from prior builts when that was important to me. The older I get, the more my goals have shifted.
I was very dissapointed in hearing the SLR broke into the 9 second barrier in January, but I cannot let that spoil my fun.

If you indeed have another 200+ rwhp & even more rwtq & obviously pull a sub 1.60 60'
In proper DA etc...
I'd see NO reason you wouldn't be able to run a Basement-low 10 second 1/4 mile

New Video up from today. This was the last and the only full pass I made to keep from getting kicked off the track (this track is very strict any sub 7.35 has to have a roll bar). This test day was good and bad. The good part is that I got the 60' times down to 1.81-1.82; considerably better than the 2.0X I ran last time. The run in this video had a 1.85 short time as the track was loosing grip quickly after 5pm and at the end of the run the car slipped completely out of gear and I coasted around to get my time slip. When I put the car in park and tried to start the car it lunged forward like it was stuck in drive. After messing around with it I finally got it started and drove straight home. On the way home it slipped out of gear 5-6 times. Needless to say it is officially time that I pulled the tranny to rebuilding/upgrade it.
While this is going on I will be installing a chrome moly cage certified for 8.50 1/4 mile runs.

Your name says it all... Dynodaddy...should be changed to Dynoqueen.
The top 3 CL's in Dragtimes are by far the fastest to date and you come along claiming 9.50's
Why don't you try running 10's first and then you state your claims on being the most powerful MB in the world. That's a pretty tall order...
Here is a little bit of math for you...
You are running the 1/8th in 7.xx seconds that's 660 feet...
I guess that means you will run the remaining 660 feet in 2 seconds... Right
Trap 148? could of just round it off to 150..What is this world coming to...

Thanks for showing everyone how ignorant you are towards drag racing.
Most drag stips in the country aren't prepped half as well as Bradenton, Englishtown, and Norwalk are every day of the year. Certainly not the POS 1/8 mile track I have been testing at. Truth be told Texas Motorplex isn't much better during test and tune either. The MB's on drag times that ran 10 second 1/4 miles didn't pull up the the line off the street and run those times. They ran late or early in the year when the ambient temp and humidity was low, iced down their intercoolers, and had perfect track conditions to knock off a 1.6X short time. They were also running high octane fuel as well where as I have not ran anything other than pump fuel. I take measured approaches to get theverything tweaked. I knocked .2 seconds off my 60ft time with poor track conditions and I was happy with that outcome until my tranny broke. I still have to do some work to do with tire pressures to lower the 60' times as I won't run 9.anything unless I can cut a 1.6X or quicker.
You are correct about one thing. My car will not run 10's until I get a cage in the car because the track around here follow strict safety rules. I cannot run at the 1/8 mile track again without a cage after running that 7.2. Once the cage is in and the tranny is sorted out the car will pull up to the track and clock off 10 second runs religously.
Mock me over the internet and continually show your ignorance if you want, that will not change the fact that the car will make many 9 second passes before I am done.
I don't care how much power the car makes on any dyno, only track times.

I have the most powerful Mercedes in the USA, you should change your signature. Who announces that they're "going to be the fastest"? It's like someone popping a Viagra and announcing that they're going to be an award winning **** star before the hard on kicks in. You got a long way to go buddy, 7.XX in the 1/8 dosen't even put you in the conversation of fastest anything, except maybe keyboard. Sorry but I'm brutally honest.

I cleared about 25 tranny codes and a dozen engine codes and tried to put down a 1/4 mile pass before I replace the tranny. Any higher than 16psi and the tranny would slip 2nd and go into protection mode. The car has to be driven in dyno mode and was really struggling to get off the line. My 60' times were more than a tenth slower and almost two tenths slower at the 330' mark than last week before the tranny started to go haywire.
The tranny is comming out to be repaired and I am going to go with a custom torque convertor to help out the 60' times. As mentioned before the cage is going in the car during this down time as well. With a stock tranny that worked properly and didn't take a full second to shift the car would run 10.7's or faster on 16psi and 93 octane. I stand behind my claims and the proof will be plain to see for everyone. The car will run the ET and MPH that I quoted. It will be a few months before I get the car track ready again to keep lowering the ET.
The video of the run is below and the incrementials were:
60' 1.936
330' 4.909
1/8 7.313
mph 102.73
1000' 9.362
1/4 11.074
mph 132.08

I apreciate your opinion and I have a feeling that you share the same opinion as most people on this forum.
To address your post - I have the dyno sheets to prove this car is the most powerful MB around. I will gladly remove that claim from my signature if you can prove me otherwise. The dyno sheets were a byproduct of tuning the car or I wouldn't have any dyno sheets at all. I already have a stack of 1000+ hp dyno sheets from prior vehicles that I have owned. They do not interest me any longer.
As for the quickest and fastest I will have the video's and timeslips to prove it shortly after my tranny situation is resolved. You are correct, I couldn't quite get in the 10's today but my 1/4 MPH has only been bested by 5 other cars on Dragtimes on my lowest power setting and 93 octane. I another 200rwhp/200ftlbs in addition to this power setting. That you will have to take my word at, or don't it makes no difference to me.
