Building Dreams Part 2 | Air intake and supercharger pulley upgrade!

Disclaimer : I have no idea what I'm doing! LOL
... I did start working on my car and got carried away with the small improvements I am able to make myself .
Honestly nervous about the car ever running again...
But
I'm so excited for whats to come.

Removing the factory bypass valve requires installing a blowoff valve of some sort. The excess boost pressure has to be bled off somewhere other than in the intake manifold. Example, when you're going from 6500 rpm and full throttle then taking your foot off the accelerator pedal. The supercharger is still making lots of boost as the rpms are slowing down but the throttle body is closed.

Quite tempted to do alot of the mods youre doing here to my 07 slk 200, what size pulley are you running? What i found is that its recommended to run a 70-72mm pulley, but from what i can see yours is much smallee than that

[@AdmJackSwallow]

Maybe put the air filter a bit to the front with an extended pipe. Right now you are probably sucking in warm air from the engine and limiting the air mass going into the supercharger.

[@RicerBenz]

the plate you cut and put in on the bypass ,is that so it only pulls air through the supercherger?

It’s to dump the air so you hear a “blow off” sound from the boost. But the car runs bad because of inaccurate readings of the MAF NOT recommended to do it

[@RicerBenz]

I would suggest a tune after you installed the smaller pulley yes. I did not use a shorter belt. Cold air intake(not like mine🤣) bigger exhaust. I don’t think the intercooler makes much of a difference I did it more for the look of it. But I’m no expert.

[@sipanhursit4040]

I have the exact same car, I want to try something like that but is it worth it ?

[@AP77432]

@@RicerBenz intercooler makes a huge diff expecially in ur 10.5 compression ratio car and with smaller s/c pulley ;) Eaton m45 are very hot. Bigger intercooler expecially with colder spark plugs will give u more tune potential. If u want more then 135 kw u can go with new headers and exhaust, backpressure also creates many heat back to engine. I saw one guy did 160 kw his w203 m271 without detonation risk. 145+ kw needs also new fuel pressure regulator or injectors (cant remember exactly which one, maybe both)

[@geraldryan8562]

Nice video, but what’s the whole point of this? New air filter, and longer serpentine belt required surely! ECU will need remapped. I had my SLK R171 200 Kompressor 2008, AMG sport model, remapped from 184 to 214 CV in Spain, cost 500 Euros, more than enough I think for this car, although I could have also gone like you, to a more drastic measure and added another 30-40 CV, making it about 255 CV plus the extra torque on both modifications. However, I did not think the extra strain on the Kompressor and engine was worth it, unless you want to race it? 🤔

The Supercharger silencer you can remove by only removing the airbox. The other muffler in front of the crank pully you can remove without the need to remove anything.

[@mrshitski8569]

Re-inventing the wheel. Looks like you lost 3 seconds not gained. All this has been done before. This engine is not worth modding. But the only thing that actually works is larger pulley, Kleeman box for the ECU that changes the fuel ratios because above 4K rpm the engine will be starved for fuel, a higher pressure fuel pump, and larger injectors. For the cost and time of all that just buy a used AMG. C32 or C63

There are two maf screens actually. 1 plastic air strightener and and 2nd thin metallic mesh screen which you can only remove. Its final protection from debris and othet objects coming from outside, if your filter goes off or got cracked as example. But yeah, that first plastic couldnt be removed, it improve maf sensor readings and reduce air turbulence. Actually it gives more power.
