looking into getting one ,was wondering who sells the max HP/Tq package on these , Turbo's ,Downpipes,tune etc Thanks

All the tuned cars make 525-550whp depending on dyno, weather, car, etc. Downpipes don't add much peak hp (maybe 10-20) but add a bunch of mid range torque. Not much difference between the different companies in terms of power output.

At least 5 or 6 vendors advertise some sort of turbo cartridge upgrade but I've inquired about dyno sheets or trap speeds every time one of those threads pop up and not a single one has provided much information. My guess is they're all still doing R&D and there are less than a handful of customer cars with the turbo upgrade. Or maybe they just don't want to sell their product.

I'm hearing 700 ish at crank with turbo upgrades ,I'd like to see 1/4 mile times etc really ,dynos are like you say ,different types weather etc.

Check my thread about the Renntech R1 package, like mentioned above around 550hp at the wheels is pretty standard and will vary slightly car to car. The R2 package adds turbo impeller upgrades, I'm holding off on that until there is a bigger turbo upgrade.

Also, if you're considering getting one and plan to tune it regardless you could consider a GT instead as the power difference is just software based between the two. For my 17 I could get the options I wanted on a GT + the R1 package and still be at lower cost than what a GT-S would've cost.

Good to know ,thanks,I agree on the "bigger" turbo upgrade , a few Cls63 guys said no night and day difference on turbo upgrades ,in fact one said if I had to do it all over I would have left stock turbos,that was a turbo wheel upgrade ,,and you have to drop motor too

Is it absolutely difinitive that there are no hardware differences between GT and GTS, just software?

boosting1bar

Yes, everything I've been able to find online says yes and my MB dealer and Renntech said the same.

Ive seen the same until this link which says 700 at the wheels with supporting mods.

if supporting mods = downpipes and cooling (nothing more drastic), I'd be interested in 700whp

Im in TX so haven't really inquired seriously yet.

I'm getting that installed on my car this week.

I'd like to see a time slip from somebody in this country,too many TT Benzs with reworked wheels,or turbos and no time slips to back up the manufacturers claims, seems like they use everyone's cars for their R&D .Big numbers advertised but no low ten second time slips ,except from the guy in Abu Dhabi

You will definitely see numbers from my car.

RBM113K

Haha awesome ��

With just a tune from Eurocharge, I ran 11.1 @ 130 stock tires

kumizi

yep

that's why i want to see one of those turbo cars trap over 135 before i'm going to shell out the money

RBM113K

Like to see a power package that puts these cars in low 10 s like some 911 s , bigger turbos,exhaust,maybe cooling mods ?

This is my own conclusion but I believe you have not seen any videos or advertising on the current impeller turbo upgrades because it does not make much difference versus a tune only car.
The only video out there to my knowledge is Eurocharged at 10.6X for the 1/4 if I remember correctly. A GT-S runs 10.9 on stock tires with tune from RT or Weistec. The slicks on the C63 run are good for around 2/10ths so it is difficult to justify spending 10K on the upgrade.
Once tuners come up with a real turbo upgrade and a time in low to mid 10s then I think people will jump on the bandwagon.

130mph means they have power to run low-mid 10s. Just need the 60 foot if you want to put slicks on your car and learn how to launch it. 911s have AWD.

kumizi

What was the trap speed of the stage 2 car when it ran 11.1? I'm interested in trap speed gained from the turbos.

RBM113K

Still I'd like to see one of these run the number before getting carA FBO , Turbo's and all .

AMG 17GT

I'll predict 130 this weekend.

kumizi

Do you actually go to the 1/4 mile track?

Because the trap speed will tell you how you will fare against another car on the highway.

I made 585 whp and 650 torque on the Eurocharged dyno with tune and downpipes. Cars sounds so better then stock and the power band is incredible. Needs a bit on the top end though (upgraded turbos) would be the solutions.

kumizi

^ I have the same but didn't dyno. I was guessing 550-560whp. 585 is strong.

I feel the same about the top end.
