M113K Upper Fixed / Clutchless S/C Pulley





I'm curious how effective the bypass will be in comparison to the clutch - could be interesting on a high-rpm downshift... could definitely impact the exhaust note depending on the RPMs


i opted to get smalled(77mm) then the small sc pulley with clutch that is on my car now.
i will dyno it to see if there is that much significant gains.
Also , just to avoid any mishaps I think you should wait until they properly configure out the tune or did they already do that ?




i was going to get it properly tuned dyno and then slap pulley on and adjust again tune/dyno
besause i think i can still get more hp the way the mods are as pre clutches pulley.

Any more news about the fixed SC pulley is highly recommended.
Does fuel consumption rise on part throttle, because according to that 55K guy, now he has even power at part-throttle...

Regarding the magnet "cover" that spins... How much does that weigh?

There is some more info on the fixed SC pulleys with pics on PSC Forums, would be nice to see them here as well - thank you :-)
3 ways the pulley is fixed to the sc shaft; interference fit , 2 factory dow pins and bolt pressure.

if it works, it would be fine, but if the ecu want to declutch the sc pulley, maybe cause the iat is too high, your pulley can't declutch, the iat's are going to get higher and higher, and i.e. at 300kmh its very hard for the engine... If something is wrong, the ecu cut the boost by disconnect the clutch, with a fix pulley you cant.
No problems if maybe the ic pump is faulty and the iats getting higher?
I ask this cause i made me a fix pulley too for my c32.

This is my biggest concern too so far. What are the safety mechanisms done by Eurocharged??? No-One is willing to give answer so far it seems.
For my case, i would never ever build any custom Gauges into my classy CL-Class coupe, and would ruin therefor the great interior look of the car. No Way.
So, if EC can do more to the ECUs Data than flipping around with Hex Values for injection and ignition timing/amount, ie. having the bypass flap open fully suddenly if IATs exceed for instance 170°F and once they are lower than 150°F put the flap back into normal operation, then it would be awesome.
If not, well that would be very bad, if no other good method is looked into (ie. cutting timing tremendously on high IATs, whatever)

I think in us the problem isnt that big like in germany - when the cars drive there 300kph for a longer time?
