I know this has been discussed a million times but my question has to do with how the thermostat affects coolant flow.

Originally I was going to use the 1/8 NPT side port on this barbed fitting that came with the Victor X manifold. But its not really big enough for a -6 AN line and Im not sure if this bypass hose gets coolant when the tstat opens. Can anyone confirm if this bypass line gets flow both when the tstat is open and closed?


My 2nd option is to tap the back of the thermostat housing like in this picture (left smaller black plug on the tstat housing). Does the back of the thermostat get flow when the tstat is open and closed? Thanks to haydenpothoven for the picture.

 

Nobody knows how the thermostat controls coolant flow?

 

This is why I stick to oil-cooled turbos. Too complicated for me.

 

i ran all last year with one of my coolant lines coming from that fitting with the victor x and then teed with the lines that go to the throttle body

 

I´ve got the Fast Turbo coolant line kit and it comes with a weld on fitting for the water pipe. If you´ll go with the second option it´s the same situation. The return line is still before the thermostat so I don´t see a problem. I tapped my thermostat housing too because I don´t want to use the weld on fiting. A 6AN fitting fits perfect!

 

Where did you guys tap your coolant FEED from?
I was going to drill and tap the bleeder valve.

 

Is your block OBDI? I ditched the factory oil cooler and used the leftover coolant ports to feed the turbo. I tapped the lower portion of my radiator for the return line.

cant really answer your question as far as flow, but i feed from a hole tapped into the tstat housing. and return to bottom of radiator.

 

No its OBD2 B18C1, so it doesnt have the bleeder valve or the oil cooler.

 

I just used the fitting off the side of my victor X that had the spot for the small line.. and i fed the other one off a T from my thermostat line...

as long as its a loop including the turbo, feed and return dont really matter IMO, the coolant system is always flowing... so as long as the turbo has coolant, you're good to go

 

Well if there isn't a difference in pressure on each line then the coolant is not going to move well.

 

On the front of the block, to the left of the oil dipstick is a fitting.

I am running my feed from there and return to a fitting onto my radiator.

Clean and simple

any chance of a photo of the radiator fitting?

 

Sorry I don't. It's just a -6 male aluminum weld-on.

 

I ran mine off that same exact spot, i used a 1/8 too 6an fitting, the i removed the fan switch and got the fitting for there and used that as a feed or return .im not sure how its flowing.But i know 1 is before the thero and one is after.

 

sorry for the bad pic..

On the left you can see the feed line fitting and in the right (thermostat housing) is the fitting for the return line.



and here´s a pic of the original thermostat housing:

The easiest way is to just put the lines between the TB and the IM as described in the instructions for the Edelbrock turbo kit. Download the instructions from their site.

 

That is not what this thread is about.
