How close to the cat. can the WB go?
I want/need to install a wideband bung in my supercharged car.
I searched around & found lots of posts saying away from the engine, in front of the cat.
I have the FM Butterfly brace & the blower in place & all the other excuses why I really don't want to remove the downpipe.
I'm wondering if its safe? to install the bung in the neck of the cat. There is about 3" there between the coupling & the body of the cat.
If that location is ok, I can slide the cat out the back to get the job done.

My one concern was that the cat heats up pretty good.
Due to the exaust flow, no problem when running, but what if I do 20 hard laps then stop. Will the heat kill the sensor or am I over thinking this?

What is the relationship between the distance away from the turbo and the o2 readings? Would the AF ratios still be accurate the further it is from the turbo? I am planning on relocating my wideband from the stock narrowband location to the exhaust, but that seems REALLY far away from the engine. But of course, if the exhaust gas velocity is fast enough than there's no lag to worry about.

Use a heatsink pas er the manual and put it in the stock location. Irll be fine.
Mines been there for 5 years and many trackdays.
Similarly my mate has a Greddy same LC1 with a heatsink and in the stock location, again no issues.
Install it properly, use a heatsink use the stock location and stop worrying about it.
