You do wonder why they included them in the vehicle then... seems like a giant waste of money, to me

 

morning all, happy Wednesday 🦞

I think it’s only the top model that gets it, but I’d rather my $$$$ back lol

Wife disagreed with me, I told her she was talking to Captain Yeah Nah and she was wrong.

 

Now my nickname is Captain Yeah Nah

haha not really an insult... but sounds like fun

[Puffwagon]

Haha yeah gotta keep life fun

 

Hey Keith did you ever find out about the rank thingo in the profile? Pretty sure I'm due for a change 

[k31th]

oh yeah... I knew I forgot about something I had to add to the to-do list haha cheers for the reminder

[k31th]

@Puffwagon; it's fixed. The field is back in the "edit profile" section under "Member Title" now. InvisionCommunity prioritized "Ranks" over "Member Titles" a few releases numbers back and they moved that field into a "retained" value, but not an "editable" value. Have set it to an "editable" one

 

morning all, happy Friday 🦑

Can someone pls tell me how tf an external gate and boost control works 🤣🤣🤣

I have been researching for ages about the "upper" and "lower" ports of a wg and I just can't seem to find any articles or anything on how exactly it works. I'm pretty sure I understand every concept behind all this, but I don't understand it when its all put together... Let me try explain.

 

The top port (or upper port) is on top of the wg diaphragm, same side as where the spring is; and the bottom port (or lower port) is on the bottom side of the diaphragm, same side as the back of the valve. 

A wg has a spring in it, spring pushes against the top of the diaphragm, where the valve is connected. When pressure on the valve from exhaust exceeds pressure of spring, valve begins to open. This is basic operation of wg.

 

Now boost control is where I get confused. The wg solenoid controls how much "boost", so added pressure, is going to the wg. Hence why the boost reference comes from the front housing of the turbo. Falcons are fitted with a very basic 2 port solenoid. It can either be open to let the high pressure gas flow, or closed to prevent the gas flow. I'm assuming this is also done via some form of modulation technique too. Am I right so far?? Hope so.

 

So in my head, if this line is fitted to the bottom port of the wg, it means that the max boost you can ever achieve would be set by the spring (or springs) you put into the gate. Adding boost pressure to the bottom port will then reduce the boost pressure because you are adding pressure to the bottom side of the diaphragm, thus making the valve open.

If you connected the boost line to the top port of the wg you'd end up with the opposite of whats stated above. 

 

If this is all true, then why is the bottom port used more than the top port? This is how its shown in the turbosmart manual too! Connect to the bottom port, and let top port vent to atmosphere...

But then at the same time it states that the spring sets your min boost pressure!? How? I don't get it 🤣🤣

 

Pic off the internet as an example. solenoid connected to bottom port. As done on my brothers too, and as I've done it on my car

@biddie_fiddler Spring rating dictates when wg valve starts to open unless boost solenoid is bleeding off air. If you hook up compressor outlet tube directly to bottom port of wg then the air pushing on underside of wg diaphragm will force diaphragm up which opens wg valve when spring rating is reached. Eg 7psi spring, roughly 7psi boost. Exhaust pressure in turbine housing doesn't usually push wg valve open unless running huge boost. I could be wrong on that. The top wg port goes to atmosphere, unless you're trying to hold valve closed with boost for longer with a whole different plumbing situation.
