I am finishing up the install on an LSA supercharger. On the top of the snout are four openings. The left (blue arrow) is for the evap purge valve (I think). The larger (red arrow), is for the brake booster (maybe?). The green circle, dunno. The orange box, dunno.


Are these all vacuum? If so, can someone please tell me if I am correct, and what the other two are for? I can't find a good diagram.


Thanks

The red arrow is where the brake booster line connects.
I'm pretty sure the orange box and blue arrow is either a MAP sensor or an IAT2 sensor.. I'm not sure... I'll have my wife snap a pic real quick of ours and shoot it to you.

Thanks. I found out from someone else that the orange box is a MAP sensor that senses pressure just behind the throttle body, before boost. But the ECU doesn't seem to use this information for anything. He told me to block it off.

The green circle is just another vacuum port. Someone answered the question for me on a facebook page, but the problem with facebook pages is there is no way to search for the answer like you can in a forum.

Anyway, I capped off the blue arrow, the orange box and the green circle since I didn't need any of them. The red arrow goes to my brake booster with a stock LSA tube.
