I would try to go more like 285/35 which was the stock tire on my car. I am sure M/T or Nitto do drag tires in that size and you have to run 20psi or sometimes less depending on tire and car weight.
I am going to try some 305/35r19 which are larger than stock however I feel we have sufficient torque to turn them. I have to use the 19" due to 380mm brakes on the back.

I think the higher sidewall give a better grip when the tire body "gives up" a bit if necessary.....

I can't find any dealer for MT tires here???
I read somewhere here that Mercedes CLK 18" alloy wheels is light but I don't now exactly which model of them?
Maybe its an AMG modell? The offset is totally wrong so I think I must use big spacers so I have the wheels more out because I have the Black series kit...

Benz car have only the tune and drop filters.
Thericker have:
-"Super special edition individual CAI Silicon tubes"...
![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
-Downpipes (without cats ??)
-Bigger Intercooleers (air density is much bigger )
-Better circulation pump
-Second HE ?
-Modified turbo wastegate (more and longer boost)
-Bigger injectors
-Same tune
So al this together give Thericker only 15 whp more.

Finally an answer from the company.
I have send them several e-mails and also ask what kind of product they recommend to use?
I have send them engine room pictures also... but now answers.![smash](https://mbworld.org/forums/images/smilies/smashfreak.gif)
Only one "Rotating answer".... I'm angry.
Next I'm gone call their boss also and would say a few selected words. There are sitting paying people in customer service and do nothing!!!!
They have a dealer in Germany also.... no answers!!!
Here is what "Steve" answer me from Heat shields products.
It’s a simple matter of airflow. When the air is flowing, the air will still heat up, just not as much as when the air is not flowing as much through the engine compartment. The image provides does not give us a good enough view to properly asses. Generally speaking if you shield the pipes after the intercooler it helps quite a big, you can also shield the pipes pre-intercooler. That does also seem to help a little bit.

Here is the answer:
Water intercoolers are tricky. You do not want to add much to them, because the metal is supposed to displace the thermal energy. You might be able to stick some small pieces of Sticky Shield on part of them close to heat source.

Bleeding of the intercooler system
Yeasterday I decide to bleed my Intercooler system to be sure I have no air there before I'm gone bring the car to the dyno.
Because I have no chance let Mercedes do it I did it my self. I'm pretty sure this a good solution to do it. It took about two hours but I think Mercedes also need two hours to do it.... so I earn some money here![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
At the pictures you can se the tools I used.
-Few O-rings at the neck of the bottle that it can be sealed filler pipe.
-That small tool is for to remove the valves.
When you are ready and want take everything of I did it following way.
-Fill the liquid at top at of the bottle.
-Then take of the small pipes (one for one) from the valves so you can screw the valve inserts. (When you take of the pipe the liquid is coming to start to run out from the valve. Because the bottle has enough of liquid it don't suck up air). If it gets emptied you fill it in time before you take of the second pipe.
At the first video clip you can see how the air is coming out...
. The engine is not run. Its only the ignition
on... I have modify the harness so it run al the time when ignition is on.
At the second clip you can see when everything is finish. You can see when I press both sides intercoolers pipes a while and then the liquid flow to the bottle from the intercoolers...
... Love to see when the Circulation pump is working...![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
WITHOUT AIR ANYMORE...![drive](https://mbworld.org/forums/images/smilies/driving.gif)
PS. You can bleed the intercoolers system same way even its OEM Intercoolers.

Elselent you need to look at installing an expansion tank as the problem with the stock and Speedriven setup is that when the system gets hot the coolant/water will expand. You will see some fluid seeping from the cap with nowhere to go so it gets lost and you are back to square one over time with air bubbles back in the system.

I am fitting an ice tank or coolant reservoir tank in the stock battery location which will also act as an expansion tank. Others have fitted a small expansion tank in the center of the intercoolers.

Hello.
Finally I test drive my car yesterday and I am positively surprised
.
Quite obviously runs better than before and I'm sure the next step must be a new differential.
Now it seems that the car tends to run diagonally when I step the gas.
.
The second surprised was the exhaust sound..... I'm not sure If I have mention before that I bough new mufflers at the car... I install them few months ago but I had completely forgotten about it...
so when I start the engine I thought what the hell ......![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
The sound is exactly what I have looking for. It's fuller heftier (more bass) than before and not as sharp. It's some what quieter also.
These mufflers fit perfect at in place of the original mufflers.

-Dynomax
-Race Bullet Muffler 24215
-In/Out: 2.5''
-Overall Length: 16.5''
-Shell Length: 12''

After I made the intake and honed the pipes inlet conical my opinion is that the engine is MORE sensitive / aggressive at the pedal. (Others may just disagree if they want to).
Its "rap"... more rap than before and the sound is also richer while before.

T-Branch test
Hello Members...![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
When I saw the T-branch first time I wonder how it works in pressure. ( You remember I have honed both inlets conical also)
- Two ends is coming from the intercoolers. (right and left).
- Big end to the TB.
It work just fine when you have no boost at the engine... because you have small vacuum there... ie sucks in air and then the air is going to right direction to the TB.
So I decide to test this T-branch and look what happen when there is boost/ pressure. Look at what direction the air is going then?... is't going to the TB or "over" to the another side to the intercooler inlet???
Of course that same pressure/ boost is also coming from the another side and stop it... BUT if it do it, it causes friction and turbulence, etc.... and benefit falls.
So I made my own "flow bench" with sensors... plastic sensors..
don't laugh please...![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
You can see at the video clip what happen when I put the blower on.
The air is going straight to the another side....nothing to TB pipe?... At TB side causing the vacuum! ( look at the "sensors")
I decided to saw a gap in the center of the T-brancht and install/adjusted plate and see how far/deep I must press it inside the inlet so the "pressured air" change the direction to TB... and you can see it at the video when I move the plate inside the inlet.... it's not so much. May be 1/2-3/4". (look at the sensors)
I did this test when I figured this to happen and it was nice to be right!
So I'm gone modified my T-branch with right size/high of aluminum plate and weld it at the gap I have made...
After this modification the boost/pressured air is going from both direction straight to the TB inlet,,,, no turbulence and friction at all.
Hope for few hp more again....![drive](https://mbworld.org/forums/images/smilies/driving.gif)

I love the test and agree that the air does not split very well.
I do not think putting the plate in that location is a good idea as you will completely destroy the total volume of air.
You would be better placing it in the center of the t branch on the other side to divert the air.

At the test I can see where and how deep the plate must be. I use that plate only to show what I mean. The plate Im gone use/made is going to be wider and proberly shorter and it must be in outside of the pipe curves.
The plate dont need to be so deep in the inlet and both inlets is made/welded so they turn a litle to TB direction.With the plate I help the air go the right way from the begining.
So after the modification the air is going faster/colder to the engine and its going to get more air than before at the same time.
So I think its better than let the air turbulence in the center of the T-branch.
Im gone test the plate many times with my "flow bench" and mark exactly where it must located at the inlet. I can se it now with my own eyes the right position. I have already honed the inner curves also.

Hi, Ekselent, from the flow of water up the clear tubes, it seems that your pump is weak or failing. I'm using the original Bosch 010 pump and if I squeeze the pipe inlet to the other intercooler, the water continues to rise in the clear tube even after I let go.
I personally have 2 Bosch pumps in series (one extra before heat exchanger and the original after) and they keep the pressure way up and a small overflow tank next to battery to keep the water level in check.
By the way, ambient temperature yesterday was 118 F (48 C), with speedriven intercoolers and scorpions, my IAT on highway is about 135 F (57 C). After WOT it reaches about 178 F (80 C) and after that it hovers between 140 F (60 C) to 158 F (70 C) unless I drive it on the highway again where it will go down a bit.
Hope my info is helpful.

It was pressure a lot there...... but may be because I have a second HE it's not enough?

No I now at which levels the IAT must be with good pumps....
My temperatures is at same levels.. some times 54C at the highway and it seems it have nothing to do with the ambient temperatures???
Maybe when the engine run at idle?
When I bleed the system in two hours the highest IAT was around 65-70C. I datalog the IAT all the time but I had the hood open.
Ambient temp was around +22C

T-Branch modification
Hello.
Today I have done the T-Branch modification.
-I made the "guide" from 2 mm thick aluminum plate. ( fourth picture).
-Saw 2mm width gap at the center of the T-Branch and weld it there.
-I measure the inlets after I install the guide plate and it's not gone stop the airflow at all. Nearly the same dia now vs before the plate. I have also honed the insides of the pipe curves.
-I test three different plate models. You can seen them at the picture 6. The straight plate was the best.
-You can see at the T-branch when the guide plate is there from different angles and you can also see there is lot of space for the air to run.
I test it again with my "flow bench" how deep the guide plate must be so it change the direction to TB inlet.
Video clip with "flow bench" :
Today I have done the T-Branch modification.
-I made the "guide" from 2 mm thick aluminum plate. ( fourth picture).
-Saw 2mm width gap at the center of the T-Branch and weld it there.
-I measure the inlets after I install the guide plate and it's not gone stop the airflow at all. Nearly the same dia now vs before the plate. I have also honed the insides of the pipe curves.
-I test three different plate models. You can seen them at the picture 6. The straight plate was the best.
-You can see at the T-branch when the guide plate is there from different angles and you can also see there is lot of space for the air to run.

Power test.
Hello.
Finally a new power test. (Dash command)
I have install the T-branch plate + downpipes with 200 Cel cats.
- Same power 667 hp
- Torgue rise from 795 to 902.
- Boost drop from 21,7 PSI to 21.
- Intake temperature litle colder. Dropped from 140F (60C)--> 118F (48C).
Is't better than before or worse?
With lower boost same hp but a lot more Torgue.

Today I made the engine covers completed.
I bought rubber edge strip u-section at the hole I made for the T-branch.
Tomorrow to Tampere and thuesday morning "true dyno runs".![drive](https://mbworld.org/forums/images/smilies/driving.gif)
and if the engine don't get enough of fuel adjustments must be made..
Hope also to modify the turbo shaft for more boost and so it hold longer.

And you are not gone use scorpion filters at al so you must cut
the upper part also different and don't cut the lower part at al. At Kamils version they have cut the lower part also
I wanted as much as possible of the original look.
Kamils engine room looks great!!!!!

Finally my dyno chart...
Im not affraid to show this... It was verry slippery. .... The power is down but the torque is amazing.
Something happen between 3000 -4500 rpm. Everyone who now and understand this chart can see the power is there. 927 Lbft at 2850 rpm.
Its because the plate at the T-branch. It get air faster and with lower rpm...
A/F ratio was al the way 11,8.
Im not happy!!!
