Hey Guys,

Finally had a chance to go out to the drag strip to see what the car would run with the EuroCharged V4 tune and the 90lbs of Rotating Unspring Mass Reduction. The results were pretty damn impressive given its pretty much stock other than those two major changes.

I was hoping to get into the 12.8's with 1.9sec 60'ft times. and although I did not quite get into the 12.8's (missed it by 11 one-thousands of a second). I did consistently get into the 1.9sec 50' time range consistently almost all day long and was running 12.9s all day long, VERY consistent and impressive for a 5300lbs SUV!

My reaction times also significantly improved and I got down all the way to 0.152. The best technique to launch the car I found out was putting the car in Sport Mode, ESP Off, and NOT to brake torque the car. For some reason every time I tried to brake torque the car to 1500rpm (Hold brand and gas to 1500rpm to launch), my 60ft' times would actually drop and the launch wasn't as good. Therefore, the best way to launch our cars is to simply hit the gas a tenth of a second sooner than you think you need to and that will compensate for the additional time for the 4wd to engage.

Overall I am very happy with the results and it goes to show you just how much rotating unsprung mass can rob from the performance of a car. With all the high end HP cars there that day at the track, I was consistently beating almost all of them off the line. Its not until past the 1/8th mile where they would pass me back (Refrigerator Aerodynamics certainly do not help above 80mph+).

Either way thought I would share the great results for those of you trying to decide on either EuroCharged tune, RacingBrake 2-piece rotors, and Forgestar CF5 wheels. Its a fantastic setup and I could not be happier.

In my opinion the car is officially done!

(The next upgrade..... BiTurbo ML63 AMG .... )

 

Interesting Comparison to Newer Bi-Turbo ML63:

Having compared my results to the newer Bi-Turbo ML63, it appears that my car is actually significantly faster than the newer BiTurbo all the way past the 1000ft' mark. Only at the very end of the 1/4 mile does the BiTurbo catchup to my current setup (and just barely). The ML63 Biturbo 1/4 of 12.821 is only 0.021 secs faster (21 one-thousands, which is basically almost dead even). The higher trap speed of 110mph indicates that it was only able to make up the difference due to the significant boost in torque & HP. Past the 1/4 mile the Bi-Turbo will pull away due to the higher HP & TQ, but still... quite an impressive accomplishment for basically just a tune, wheels & tires, and brake rotors.

More importantly, compare my 60ft' times of 1.973 to the newer ML63s time of 2.119 and you begin to see why Rotating Mass reduction is so huge at lower speeds. In fact, nothing could really keep up out of the hole as I was launching faster & better than anything else out there. Granted the high HP cars would catch up to me mid track and pass me, but for city driving this setup is perfect. I get out of the hole significantly faster than the newer Biturbos as well (and remember, that is include the massive torque disadvantage I have compared to the newer biturbos which make peak torque at 2500rpm+). Imagine the newer BiTurbo's times with 90lbs of rotating mass reduction and EuroCharged tune


Newer BiTurbo ML63:
60ft = 2.11 (slower)
330ft = 5.592 (slower)
1/8 mile = 8.426 (slower)
1/8 MPH = 86.99 (slower)
1000 ft = 10.852 (slower)
1/4 mile = 12.892 (faster)
1/4 MPH = 110.56 (faster)

 

drop 3k on (tune) in the biturbo, and wave bye

 

Haha, obviously, my point is for almost a third the price you can get the 6.3L ML63 second hand and get same level of performance. Gotta factor in those $$$$

 

6.2L - LOL

Nah, but in all seriousness, that is so impressive. Cracking 12s consistently. Love it.

I hope to get over to the drag strip soon, and try my car.

Though, my mods are a little different.

22" Rims with PZERO Scorpions. (i would think these rims are significantly heaver than the stock 21's)

OE Tune

Resonator Delete

+ i have factory Rear Entertainment option & 12" Sub & Amp

But i will make sure to drain my washer bottle, and drill holes in the tissue box thats on my rear seat!

With VBOX, i havnt run a quarter mile, but the best 0-100km (62 Miles) i could get was 5.06 Sec (crap road though, def not a drag strip type of bitumen)

Anyhow, love your results! Keep it up!
Remove spare tyre, and rear seats next time.

 

ML63AMG

Can you post some pics of your car? I'm interested to see it on the CF5s in 20"

Thanks

 

Sure thing:

I have very similar mods, so cool to see your times.

Tricks to squeeze out a few more tenths in the quarter mile:

Raise tire pressure
Remove all extra wgt... Tools floor mats glove box stuff spare tire etcccccc
Wait for good weather to make hp.
Let truck have good cool down....
Ensure good tune up clean af's etcc

How does this time mph compare to a bone stock 6.2 l?

 

Stock is usually 13.4-13.6 at 105mph with 60ft times of 2.1-2.2 from what I have read

 

 

Hey guys,

Going back to drag strip next month again to do comparison test of new Eurocharged V5 tune + Blip combo... Shooting for 12.7s. If I pull it off that would be an unreal performance for a car which is barely modded at all other than ton of weight reduction, air filters, and resonator bypass.
