Default Connecting Plumb Back BOV to silicone hose?

Ok, I have a Blitz BOV on my '91 Miata DIY turbo setup. It vents to the atmosphere. I find it too loud, as I am going for a stealthy setup. I have just bought a Turbo Smart dual port BOV and plan to use this to plumb back into the intake.
My setup has a 90 degree 3 inch silicone hose connecting the air filter to the turbo.
I am wondering how I should connect the outlet port on the BOV into the silicone hose?

Please see photo below of the setup, showing the 90 degree silicone hose. Please ignore the other hoses, they have all been replaced since that photo was taken.

Note that I have a FM/Link ECU, with MAP sensor, so I do not have the MAF concerns to consider.

Thanks
D

Anyplace preturbo will do it. Into the elbow; before; or after will work. The quietest would be right at the turbo inlet.

Thanks older guy, thats what I thought.


My question is not so much where, but how? I was thinking of drilling a 25mm (1 inch) hole into the silicone hose, but what do I use to connect the hose from the BOV to the inlet hose/pipe?

you could put a 45* bend after the silicone....and drill and tap into that a 1" pipe. Gotta move that alarm :gay:

I've done it into silicone...it was very ghetto.

Cut off a couple of inches from the silicone 90* bend and splice in a hard pipe. Drill and tap the pipe. Will require two additional hose clamps.

Thanks for the input. I have decided to buy a Turbosmart 3 inch T-Pipe and put it between the air filter and the silicone hose.

and by the way, I moved the alarm.
