Even at 2bar it is no spinn even on 1th and 2th gear, amazing!

People like to dog on the 4-Matics but a few of us have it figured out.

I can get my wagon to spin all 4 but it takes some serious G's to break it loose. In a straight line though, barely a chirp. I'm prone to power braking it, which will start to spin the rears sitting still. The brake light switch will keep the case from engaging until you release the brakes. Light turns green, off the brake and full throttle, the case will engage, the fronts dig and the weight transfers to the rear, it'll leave with proper violence. NOBODY expects that from a beat old wagon.

My next (privat) project will be 4matic!

I found some vids with some test runs
Drag radials on the street, a lot of spinning but better luck next season with a real slicks and real drag track

Blueberry test run 1/4 on the street with spinning all the way - YouTube

outside

I have driven my ET street radials in normal road (0.9bar = driveable) and there was no good traction. Best traction gave some normal 205/60 R17 tires with 1.1bar pressure and those was still some driveable. Otherwise normal tires dosent work in track at all... Allso the rear suspension needs to be trimmed, but these are kind of things you might have allready tried out a million times, but I just mentioned to inform people....

Roman, do you have a dyno with TB70? I am interested how the torque/hp are distributed with this turbo.

yes, m103 with 70mm inducer turbo (TB70 and your GT45 are both 70mm inducer right? but maybe TB70 a bit faster spool up?)

Yes both has 70mm inducer but TB70 is faster because it has lighter shaft and smaller turbin wheel.
Now i have only tb70-04 on this computer, it is biggest 1.15 turbin hosing.
With -03 hosing 0.84 it is much faster.

This is power on the wheels boost 2 bar, engine power was 720

Today was Ramon helping us to make some custom parts!

Made some custom fuelrails to different clients today and some mercedes turbokit parts is ready to ship to Renntech in USA.

Hey Roman what kind of differential and rear axle joints do you use? That they handle this much power!

honestly i dont know. I just bought some at the jmercedes jankyard.

It is 3.07 diff 210mm LSD
Actualy I have been running even 185mm diff LSD and I broke a few but it took pretty long time and much miles to brake them.

But 210mm seens lika impossible to destroy

PUMPISH · #**763** 02-17-2014, 07:48 PM

some late client cars updates:

Intercooler for stock radiator fit 300ce

intake and water pipes for both 300ce and 4-matic

4matic intercooler+oilcooler package

Cooling package

4matic pipes and downpipe

And blueberry got new 5" outer lips making rear rims 12,5

ECU and 12v station 4matic

Hi there...

Am a fun of your since I started turboing my w202 m111
I ve had lots of problems with my car because I couldn't find any info ...
At last I have a nice result ... I made 630ps at 1.8bar on the dyno with 76kg nm....

Am very glad with the results and I love street racing with bigger cars...

I am having serious trackion problems...I had a drag race and did 13.4 with 198km with 0,8 bar boost and 14.7 with 1.8 boost... Am running 2.3 bar now with water/methanol....

Am serious thinking of turning to automatic... But I thing I ll go for 722.6 with ole controller and paddles...

Can I go 4matic on the 4cylinder?
4matic can be used only in 12v ?

Please help me man...

From Greece with love!!!

Thanx
