Anyone heard of this car before? Does it really produce over 920hp with possibility for over 1300hp? It sounds like the 5.5 biturbo so if this is true, can it be replicated on a LHD E63 S? FYI, just click on the video to watch. It was created by GAD Tuning and DUBCustoms.

hyperion667

kind of hard to tell what's what on that tiny clip, I have read about GAD making some huge numbers........I think one of our members works with GAD quite often on his cars

Zod

The guy with the 4matic e63 from Russia is running their setup now and also claimed 900 on the musco ulimited.

looney100

These guys making 900+HP, are they doing it without reinforcing the engine's or transmission's internals?


Can these things reliably handle that kind of power?

sdg1871

Weistec is coming out with a new Turbo upgrade that will produce 1000 horsepower.

chiromikey

I've never seen a 900+hp car have trouble smoking the tires but I guess it's possible...and if it's awd then I'm even less impressed with that launch... :-/

Zod

Here you go mate for reference


the same car has these vids as well, but was renntech at the time

pretty impressive and the guy posts from time to time, seems friendly

sdg1871

The E63's 60 foot times with the GAD mods was terrible but the car was super fast by the end of the quarter mile and even more so by the 1 km mark. Typically of what I Would expect from giant turbos -- slow on launch and take a while to get going. But a killer in a roll race. Not great for daily driveability but great for a half mile or mile event or roll race.

hyperion667

well put, wish I could compile a thought such as this
it was slow to go, but incredible in the middle and ending

chiromikey

I guess those turbos are just way too big to see a true performance gain until far out speeds. While the mph is impressive, the 1/4mile time isn't for the claimed hp.

Zod

Well depends what you are comparing it to.
If the turbos are indeed large then 1/4 would be effected.

No offence but i don't count a preped track with race fuel, drag wheel setup, removed seats, tools, perfect race weather conditions and so forth an every day situation your car will be in.

There track is a normal road, that's it

chiromikey

No offense taken but are we not talking about a dedicated event on a closed circuit that had a full tree with 1/4mile and 1000M traps to measure times and speed with cars that are there for the specific purpose of RACING? How was that any closer to an every day situation?

You're welcome to talk about your preferred type of race but I too am allowed to observe that the 1/4mile time for a Benz with over 900 claimed hp is disappointing.

UrBusted

The times on dragtimes can't really be used as a quarter mile time. All the aim of that race was, I guess as well as all other dragtimes races, is to see fastest and quickest speed in the 1000m. I admit that I'm in no way a better driver, but I think the starts are a bit late.

Hi everyone! That's my car on Dragtimes Moscow Unlim500+. First of all this is a 1000m event rather than a 1/4m event. It is held on ordinary road and the car was on DOT tires and with full interior! Average 60ft was 1.9-2.0 which can illustrate the traction. Please don't compare it to the prepared dragstrip with glue and drag radials. It is like comparing apples to oranges. However the 140mph trap speed can give you a hint on the car's potential in ideal conditions. My car now is back to Stuttgart, where GAD are busy with their top kit on the basis of a built 5.8 stroker. Well i hope this time i could go high 9 for 1/4 and trap 150mph+ in ideal conditions. I will keep you posted for sure, don't worry!

JoeNobody

Absolutely awesome setup!

Did the engine have built internals? I assume the transmission and driveline had some work done.

sdg1871

Your car has amazing mid range and top end. How is the launch. I am assuming the turbos are much much larger than stock.

chiromikey

Thanks for the input and I do understand it's hard to get good 60ft times without some track help. I'd definitely like to see what your car is capable if your tuner finds a way to launch on boost. But our platforms have never been tuner friendly so your guys will need to be good! Any hints as to what all has been done?

vkudenko444

At the event the engine was stock, turbos were based on the CHRA from GTX3076 and the MCT was built by GAD to hold the torque and power. Besides i have GAD direct air intake and a 2-intercooler setup (like SLR) instead of OEM 1-intercooler in the hot V.

vkudenko444

The launch is the main problem with 4-matics. Unlike Audis which have variable torque conversion between the axels, Mercedes in AMG has a fixed 67/33 ratio. But the main problem is ESP which you can't turn off at launch and when the ECU notices yhe wheelspin it just cuts off the power very roughly and it takes a while when it considers it can add it back. Hence you get a 1.9-2.0 for 60ft. As of now GAD can't crack the ESP and 4-matic torque conversion to be like Audi's one. But came up with 245/295 tires which work better with the OEM torque distribution than OEM 255/285 sizes.

vkudenko444

Well as i described earlier the main problem is ESP and fixed torque distribution rather than turbo lag. Anyway i hope that on proper dragstrip or on concrete at the airfield (like your Shiftfactor events) the grip will be much higher and i could realize the power far better. Well and hopefully GAD cracks the ECU further to calibrate the ESP to let the wheels spin without power cutoff at launch. I will keep you posted.

Zod

Good luck and thx for posting

Do you have a picture of the inter-cooler setup, or does GAD have one ?

vkudenko444

Sure, here you are:

Thx !

You really do know your stuff. Yes the APR tuned Audi RS7s get off the line much faster and post far lower quarter mile ETs (my friend's does 10.3s) than the E63 S. My Porsche 991 Turbo S also has the variable torque vectoring and when using launch control allows exactly the amount of wheel spin at launch without cutting power that makes the car take off and launch the fastest. AMG just has not designed a great launch control/race start for our cars. This issue does not matter in a roll race from 60 mph where my Renntech tuned E63 S has beaten APR tuned RS7s.

With the gargantuan amount of power and torque that your car has the launch must be a real challenge. Once underway the car is blinding fast.
