Trask turbo question

[dheath9994]

Today after going for a ride I noticed this threaded hole on the top of my intake. Went back thru the install book it makes no mention of the hole even tho you can see it in the pictures. Kit didn't come with a plug of any kind and I can't see all the way down but I think it goes straight thru. Anyone know what this is for (pre tapped for water/methanol nozzle?) should it be plugged if not being used?

You could be correct. If it's after the turbo it could also be for a pressure sensor/boost sensor. If it's not being used I would plug it because after the turbo you are loosing boost, before the turbo you may injest some unfiltered air.

That's the plenum pic if I'm seeing it right. So would be a boost loss. You try to see if it blows out while in boost or any time while running? For curiosity sake.
