So ive been wondering what the pros and cons are to wet and dry intakes if their are any.

Only pro i could see is that the coolant running through the intake might cool incoming air but im just taking a guess.

 

I think you have this backwards: Once the engine is up to temp, the coolant will be ~195*. Air/fuel going through the carb will be is few degrees BELOW the ambient air temp so,... the coolant will HEAT up the air/fuel mixture not cool it.

If you live in a cold climate the heat from the coolant will heat up the intake and possibly help prevent the carb from icing up.

 

That's actually a great question! I'd never considered WHY some intakes are dry while others are wet, just that some ARE.

The intake doesn't need the cooling-the block and the heads (where the combustion happens) is the part that generates all the heat, and even 195 is downright chilly compared to combustion temperatures.

I think the reason some intakes are wet is just how the engineers decided to route the coolant on that engine.

You got it. It's mostly just a matter of architecture. Of course this is not to be confused with wet vs. dry in fuel injected applications where a wet intake means that both fuel and air flow through the manifold, typically in TBI where the injectors are in the throttle body. A dry manifold means that only air flows through the runners and the fuel is injected down stream near the ports in the head.

 

I was thinking it was just typically how they decided yo route the coolant around the block too. But i thought that maybe their might be some type of added benefit for doing this.
