C230 Sport Coup

My car has an eppeleptic fit after I removed the MAF screens but was fine after a while.
Yeah, do the "Learning in the recirculation flap".

Where exactly is the flap? the box over the supercharger manifold that had to be removed you mean?

C230 Sport Coup

No remove the air filter box.
It'll be on the left when standing in front of the car. Rubber hose from
airbox to it.

O.k. Thank you very much, I'll give it a try. Can this procedure make check engine light go away?

Or you have a boost leak

If your code is for the wastegate solenoid then it would go away

I noticed today that one of the sc manifold bolts is missing, I'm assuming I'm probably losing air. I guess I'll find out once I get another bolt.

Where is a good place to order the bolt and a new hose that goes into the valve cover

I doubt one bolt would make it lose air if the other 5 are tightened well. It should he the wastegate solenoid because I realized everytime you disconnect the wire you have to reset it. Also if your PVC pipe is not on try not to drive your car too much because it will leak oil into your entire intake system. Which looks like already happened since you had oil in the MAF

I found the problem. A hose behind the airbox was left disconnected, once I put that back onI am getting full rev again. I put tape on the pcv hose just to test the car but I'll replace the hose before I drive it any more. I guess I still need to resrt the wastegate too.

Just thought I would bump this to the top for a second to remind everyone why these forums suck so bad. A bunch of moderators and people with questions but no answers don't make a good resource. And everyone with knowledge gets chased out of here.

I have been STFF for information on the silencer removal for hours, finally thought I had found a thread where someone was going to provide useful information and BOOM the mods ban him. This is why people who know what they are doing leave this place in droves.

I had a similar run in with the mods a couple years back where some guy who had no idea what he was talking about told some poor kid his engine was going to blow up. Since I had over 2 years of experience working on cars as a job at that point I corrected the guy and informed the OP that his car was fine. The poster then informed me that because I only had a couple of posts and he had a couple hundred (most of which, btw, were things like "good job" and "STFF newb") I was automatically wrong even though he admitted he had never actually worked on the parts he was talking about. And I got an PM from the mods informing me that if I disagreed with him again I would get a ban.

What a wonderful resource this place is. Btw, your format ***** *****. You can't find ****, you don't consolidate any useful information in a usable way and searching the forums for something results in 100 hits of people saying STFF and 1 dead link to the only time anyone answered the question. Just thought I'd bump this to the front so a couple people could see it before I get my ban and this gets removed.

Seriously? You're complaining about a ban from 8 years ago? That's a pretty persistent grudge. I can't even figure out who it is that got banned.

Any one ever tried bypassing the supercharger air bypass vaulve? I did it and i recieved quite a bit more boost. somewhere around 10-12psi. Whats the deal with the air intake resinator.

DACHIGGA

How did you bypass it exactly? pics?

jmongar075

I don't have any pictures bit I can take some here soon.. But I took the vacuum line from the supercharger and instead of it running through the electronic vaulve and bypass valve, I ran it straight to the intake, and just plugged all other hoses

DACHIGGA

Yes pics please.

jmongar075

Any one ever looked up on the electromagnetic clutch to the supercharger? If you could supply power and ground without the sensing circuit.. Could you be at fill boost at all times?

DACHIGGA

Theres no clutch.

jmongar075

Actually there is.. And from my understanding it acts as a ac compressor witch allows your rotors to free spin at certain times.. Also has anyone done an upgraded Intercooler? I am picking up one friday and was curious if anyone has had any gains

DACHIGGA

Actually there isn't.

It's an Eaton M45. There is NO clutch. It spins all the time.

Don't believe me, go take the supercharger out of your car and have a look. I have.

jmongar075

You are correct my bad..'I read wrong on All-Data.. But if you have had it apart then you know where the intake resonator is?

JDM_love

By the bypass valve do you mean the recirculation flap? If so, I did that back when I had my c230. Before I sold it, I ultimately wanted to replace the recirculation flap with a BOV, since I didn't like how the recirculation flap was unpredictable, at least on mine it was.

As for the upgraded intercooler, I never bothered since heat didn't seem to be an big issue, even on hot summer days in florida. A big intercooler on a supercharged car isn't a great idea unless you're running a lot of boost.

The intake resonator is just for sound, won't increase any hp. It's located under the supercharger manifold. You have to remove the black oil catch can system, the recirculation flap, the manifold and then remove it from the manifold and re-install everything.

Sorry to dig an old thread but it's one of the best threads I've read anywhere... thanks all who had useful input!
