It depends on many factors,
Mk7 R at the range of 640 whp managed to get 9.5 1/4 mile with different turbo kits

At MRC they managed 650 whp with G30-770,
So high nines is achievable for sure.

G30 - 900 & 1050 were available at DBV2 at the time I ordered at same exact price for the 900 kit and slightly more for 1050 one.

One of my goals is to reach high 9s but at the same time , keeping the car away from being too laggy at low RPMs
770 is the right balance for me.

My questions to @Drew & Diggs, give us more details on the car, tune and the full setup ( transmission, fuel, water meth , boost levels, suspension, tires , wheel , full weight or not …etc ) ?!
Did you try MRC tune before ?!
And how your cars feel at low rpms with the 900 kit ?!
Probably and for sure 1050 is extremely laggy and will be purely drag racing car (for me i like to enjoy my car , not daily for sure but at least in the weekend).

Note : MRC managed 10.4 1/4 with TTV5 104 RON fuel (30c summer day in Bahrain at the drag strip)

Thanks

We don't have MRC over here.
Did they achieve that with customer cars or just their in house car which they don't release details to the public about what all they did to get into the 9s? Are they going to be performing all those same modifications to your car as well?
Everyone has different definitions for laggy. A 770 is still pretty laggy. And yes, if you want to daily drive a 900 or 1050 is probably not the best turbo to run, they'll be worse.

I wish you luck on hitting your 9s. Looks like a solid build. Have fun.

Thank you dear,
All are customer’s cars,
My car will be the second MRC tuned car with this Garrett turbo.
The first MRC car in our region (middle east) was a seat leon cupra ~ 700 whp (obviously not a drag car) but my car will be first R in the GCC.
No secrets (its a custom E85 tune with water meth , bigger port injectors and dual LPFP with lines) 2.7 bar of boost

With supported mods and some suspension tweaks (weight reduction for sure)
High 9s is easily manageable with our platform now a days , but people lived in the 10s era for a while and can’t realize it’s achievable until they see it over youtube or FB.

Ecotune managed 9.3 with this engine and dq250 (not sure which Garrett but I believe its 900 or 1050)

All of my car's info is in my build thread, way too much to list here in this post. Just click on my signature at the bottom where it has my current whp and wtq numbers and it will bring you to it. The first page lists all of my parts installed and parts that I have waiting to be installed.

9's are slowly becoming more achievable with this platform, more so with R's than GTI's. To get a MK7/7.5 GTI into the 9's takes a lot of work and money because it's FWD.

If possible, please document the build/progress on YouTube. Super interested. Not everyone is on social media. 😉

Quessam,
I see your running the Bilstein B16 Damptronic Coilovers setup. How do you like these Coilovers? I'm currently running these in my 2017 Golf R and experiencing some knocking driving over large bumps at slow speeds on the front shocks. I was told to cut the bumpstops. I recently cut 2 nubs off the bumpstops but the noise is still there. I was wondering if you have experienced any noise like this on your B16 coilovers and what you did to fix the issue? I am currently using ECS Tuning HD front strut mounts. Really appreciate any help on fixing this issue. Thanks...Love your build.

I had nothing but problems with my B16's in my previous R. The ride was terrible, they make a lot of noise and they are harsh AF. I switched to the Ohlins road and track and it was a NIGHT and DAY difference in every way. 10x better!

I have them currently, and have zero issues. No noises, clunks, and not harsh AF.

Hi Mate,
Thank you for waking up this thread again, and for you all; in order to update you about my lovely project
i finished the mechanical part of fitting the DBV2 Kit after building the engine (I ended up going with G30-900 for several reasons (mainly for my 1/4 mile target).
Finished the multi map tune with MRC:
Map 1: 1.9 bar 98 RON
Map 2: 2.2 bar 98 RON
Map 3 : E70 - still fine tuning this file (i made some adjustments on the fuel setup)
I used to use dual walbro 450 (PR stage 4 with hobb switch that will trigger the secondary pump at 13 psi of boost)
But i Moved to PM4 dual controller cause the hobb switch wasn’t consistent triggering the secondary pump (i will not gamble fuelling at this level of the project)
Just waiting for the weather here in dubai to get better (50 c out those day - and humidity is killing you how about the car)
The car now is in sleeping 😴 mode until October (will dyno it and finalise map 3)

As an overview of my experience with this setup - not neglecting the boost lag
I am extremely happy how i kept the identity of the car (4 cylinder) at the same time , it’s completely different animal when it comes to boost delivery (reminds me of old days and JDMs cars)
You will not believe me that you still can daily your car if you want (of coarse it depends on your goal with it) but i assure you , you will never find a car that allows you to do all that mods and at the same time still giving you the feelings of daily at a press of a button (multiple maps is crazy).

Its costly investment- but for me i am enjoying every single part of this journey

Will keep you posted about HP figures and 100-200 times
