Food for thought here: With any set of Twins the air temp coming out of them is HOT, way too much restriction for it not to, but even with all the restriction when you turn that loose inside an intercooler that flows like one of the square tube ones the air temp drops dramatically... ... ... it super cools to an extent. It then begins to heat up once again when it hits its next restriction(intake pipe, head ect. ) that's when you hit it with water to keep it there. Depending on the outside temp my intake temp runs between 110-125 degrees at the hat with water on, the 125 was with a shop temp of 104 and no fans... ... . you can do it with just water but it takes allot!
