Default jealous of your engine bays

Well now that its getting warm here in IL, I'm looking at all these pictures you guys post, and think why does mine look so cluttered, and yours so empty. So here's were I get to the point, which is..... what things are no longer needed when running MS. Here in my town in IL there are no emission laws. Ive heard of people removing the charcoal canister which is alot of space taken up. and I've seen where braineak has this on the intake manifold blocked off (circled in pic below) what is the function of this? any bad effects with it blocked off. I also plan on getting my A/C Evacuated so I can drop that.

The device you have circled is part of the warmup system. It's an air valve that permits more air to bypass the throttle plate when the engine is cold, thus raising the idle slightly and preventing the engine from stalling.

You might be able to compensate for its removal by increasing the duty cycle of the IAC valve, or you might not. I've never tried it, since I like my engine to idle properly when cold.

it has nothing to do with emissions or ms or a/c

its an air valve. when the clt temp is below 70*F, it's open to allow air to bypass the TB for higher and smoother idle. the end. before the coolant reaches the air valve, it passes throught the idle valve to help prevent frost inside the pipes.

Here's a diagram of how the system works:

I should take a picture of my engine may to make you feel better. It's about the most cluttered space imaginable.

You should see Stephanie's Her car is the BEGi test mule, so it's got all sorts of interesting gizmos under there.

Brain, confirm that MS in no way uses the air valve on the intake manifold... and I can fab up a blockoff plate and cap off the coolant lines at their source. I too am a fan of "neat".

It's a passive system, controlled by the temperature of the coolant, not by the ECU. Therefore, the MS doesn't use it, the engine uses it.

mine's gone. all is has is like a thermostat in it, no wires or sensors. So there shouldn't be any reason why you couldn't adjust your tune to act normally without it...even though i changed nothing and it's been fine

You want a pretty engine bay or comfort? My car has power steering, AC, Cruise, all the emissions gear, big radiator, stock fans, etc. It would be a whole lot cleaner looking getting rid of the comfort items but I'm old and it's a daily driver. Giving up all that comfort isn't worth having a tidy engine bay to show off!

+1 for neater engine bay, but I too am a fan of comfort....
That said I'm keeping my AC (Miami), and PS (*****), but since i have no emissions and I do have MS, I'll be following along to see what can be taken out, and how...

On a side note that charcoal canister looks like a possible spot for a catch can...

As promised, the "yes, there truly is an incredible amount of **** under my hood" picture:



Ignore the Vortech FPR on the firewall. Its only job is to accompany the CARB sticker right next to it.

I considered removing the charcoal canister until I realized the hardline going to the canister and the hardline going away from it are different sizes, making it difficult to loop the line securely. Something about having a potential gas vapor leak near my alternator didn't set well with me.

Brain, I know there's a shaped rubber gasket on the valve that fits in a groove carved into both the valve and the manifold. Did you leave that gasket in place? If not, what did you use to ensure a tight seal.

When I remove this thing tomorrow, any suggestions on what I may have to do to get it to idle right if it messes anything up?
