I'm kinda new to older vicheals, so excuse my ignorance please

About a week ago i bought a 84" thunderbird turbo coupe with plans on making it into my new daily driver (my5.4L isent cutting it).

Heres a few questions I have...

Where is the BOV located in the engine bay?

I cant find what liter it is...Its astraight4 cylinder EFIwith twin turbos.
Does anyone know how i can find out? No owners manual...

Also my boost light and over-power light works when i start it up but doesnt work when im driving. What do you think? Am i not driving fast unuff? lol

Thanks for your time!!

 

The wastegate or BPV (ByPass Valve) is usually on/in the turbo itself. It regulates the boost andexhaust pressure/flow. The actuator is a vacuum operated valve on the turbo. The valve would be a good place to look as a 20+ year old diaphragm (if original) would be prone to rot like in any older turbo. I think a BOV (BlowOff Valve) is used in superchargers? Not sure if turbos have them? (Although maybe they should after what I saw one turbo do). 4 cylinder turbos in T-bird were in most cases (unless non-factory) 2.3 Liter engines. Maybe not driving fast enough? (unless you've flattened the pedal to the floor on takeoff from a dead stop to test). Twin turbo????? I knew about the single deals - didn't hear about those. A single turbo has two turbine housings. One inflow and one outflow -- ??? Maybe that's the confusion?

 

I think you were right about all of those, sorry.
Ive never owned a turbo charged or supercharged car in all 24 yearsmy life. Im new to this.
