does the treadstone lower ic pipe have the connection for the hose that goes to the boost solinoid or manifold or where ever it goes? or do u have to tap one in urself? pic has just the connecton for the map sensor

 

I just ordered this pipe. I'll let you know when I get it I didn't even know there was a connection for the boost solenoid. I ordered the direct stock replacement, not the MAF relocate one.

 

well idk where it goes, i dont really look, but there is a vac hose connected beside the map usually

i need to change out my hahn, that **** rusts

 

I never noticed a hose on my stock one but I never really looked......

 

treadstone had told me they can tap a vaccum fitting if you want one, other than that they just want you to relocate that line.

 

REALLY.......

 

yup it took me around 6 emails to get a response from them over a 3 week period and finally i asked them how much itll cost to have it put in never got a response and finally they said just to call them, there customer service is horrible.

 

Calling definitely works better. It's like reverse for ZZP.

 

My Treadstone lower ic pipe didn't have a vac line going to it. i didn't think any (including stock) of the lower ic pipes had a line go to it.

btw, Treadstones customer service is actually top notch...but you need to call them. its wayyyyy quicker. emails usually take a few days but calls are instant. they will do anything to make sure you are satisfied.

 

Yeah, the stock cold side I/C pipe does have a vac fitting. I looked at mine this morning. It's just to the left of the MAP sensor.

 

hm. wasn't aware. i took my stock one off and replaced it with the treadstone and i dont remember seeing a vac line haha

 

Then you prob have a vacuum line dangling! Haha!

 

ill have to check that out :/

 

So where does the Vac Line go to? I'm getting ready to install a TR8 and piping in my HHR SS.

 

go look at everry other lower ic pipes on the market, they all have them. including stock.

 

im gonna go look where it goes, and where i can relocate it

 

ok ya the vac hose goes to the black thing with the 3 hoses connected to it on the manifold. what is that?

 

its a boost solenoid

 

is that what the little hole is on the temp sensor pad? i notice on all aftermarket pipes except treadstone

 

Can't be hard to tap with a Brass fitting.

 

But why should you have to on a brand new piece? Is the Treadstone intercooler customer for the Cobalt or is it a generic one we are using?

 

How ridiculous that they don't supply you with a vac port. That's just useless! Way to go, Treadstone.

 

ya i dont wanna risk wrecking the paint job or screwing it up and it just being a paper weight because something that should be there isnt. im gonna tell them to add one if i decide to buy one, wish they would just add it seeing it should be there

 

Well for people that don't need one its not an issue. Besides its not that hard to just relocate it anyways....



Top line coming out of the solenoid is supposed to go to the lower CP... You need to connect it to a boost pressurized area, like the manifold there... the line from the intake manifold goes to the vacuum tank so you just splice it in there and your done.

 

why would gm put it on the ic pipe if u can just do that ?? weird
