Hey guys. I thought you might like to know about this one. Today my knock off Turbo Smart boost controller arrived in the mail. Before installing it I tried blowing through the included T piece / check valve and got nothing in either direction. I didn't like the idea of putting that on my car so pulled it apart.

 

The spring and ball were the wrong way around! Any boost pressure would have closed the passage to the actuator tight, potentially blowing your engine!

 

This bit's optional......

After putting it together the right way I still could not blow it open, so I trimmed the spring down until blowing as hard as I can it just opens the valve (I ended up with a little more than half the spring left). I figure that needing a couple of pounds of boost just to get pressure to the actuator isn't a good starting point for accurate boost control. Of course I could have totally stuffed it by doing this. Time will tell.

 

Once I have chance to test it I'll deliver a report on how it performs.

 

I think the human lungs can only produce about 2-3PSI or something, that's probably the reason you couldn't blow through the boost tee.

 

If you have a spare boost gauge you can test this...

Edit: found some info

Tight squeeze there with the headers and the steering column.

Looks really good though.

Nice work Jay.

Hey Danny, see if you can download the workshop manual (I think it's a sticky in the vr4 forum). Check the Chassis and mechanical section and you should find the diagrams there (source: I was looking at this yesterday ).

bump!!!

Well done Jay, amazed to see you got it going in such a short space of time. Looks impressive too. Can't wait to see and hear how it works.

Nice ride mate, turned out pretty sweet
