coolant flowing through intake manifold

[robertc68]

I have been discussing egr cooler delete stuff with a coworker,is the o
nly reason the coolant flows back through the intake , to return it or is it to add heat to the intake too( this what he believed adding heat is good) .I am thinking if you can keep the intake manifold cooler it would be a good thing or is that not an issue. Now I could be thinking to much on my race car because a cool intake was good,does the same go for our trucks? I see some companies like gogo block off the flow return through the intake.is that why? ? Thanks Robert

You are correct about the cool air. Any engine will benefit and have more power with colder air. The only thing that NOS does is cool the air off so that it is more dense therefore you get more air into the combustion chamber. More air means you can put more fuel in which means more power. That is for any internal combustion engine.

What????? Nitrous is made up of 66% oxygen. With the extra oxygen in the cylinders you can add more fuel to create more power. True nitrous may be colder, but that is not why it helps to make power. If that were the case co2 would be a great power adder. LOL The atmosphere is anywhere between 19%-23% oxygen. That is why nitrous can be such a power gain, it is oxygen rich!!!!!

So does the coolant that flows through the intake( the return) make it warmer to the point the whole intake temp gets warmer?

It flows through the intake for the return. It isn't in there long enough to cool or heat. It is a short distance.

This is a picture of the 03.
