Any ideas where to fit a small boost gauge (A pillar)? and its pod.

Gaugue is small size approx. 50mm diameter.

Thank you in advance.

 

From the cars I have seen A pillar or steering column mounted have my vote.
Mine is on a centre pod so you have to take your eyes off the road to look at it.
But it does show max boost which you can check after your drive.

 

Cheers! .
