White dust in intake

[kingtut]

Thinking there is some corrosion that happened between the intercooler and the intake butterflies. Opened them up and there is more white dust inside. Should I be concerned? Haven't started the sled in over 2 years...been waiting on exhaust parts sadly.

Here is what I'm talking about.

That looks like corrosion you get from various types of race fuel, what type of fuel are you running?
You aren't spraying water/meth are you?

Just pump gas. Highest octane I could find, usually 93 or 91.
