coolant => manifolds

i'm a newbbbbb here at these cars.

does coolant flow through our intake manifold into the head?

I'm not sure but I hope it doesn't flow through the intake manifold. That would heat up the incoming air. I know it flows through the throttle body but thats to keep it from icing up in cold weather.

coolant doesnt run through your intake manifold...

if you live in a warm area u can remove the coolant lines from the throttle body and plug them... 10 hp gain

ummmmm...... sorry, but no.

Im sure the coolant lines are there to either cool the egr valve or another heat related exhaust device or else it wouldnt need to be there. dont plug it and no, youre not getting 10hp from doing so either (butt)

Actually you can remove it since its only to keep the throttle body from icing up and sticking. But hell no you won't see 10hp gains

Do a search for throttle body coolant bypass and you'll see that tons of people in warmer climates do it. But its akin to lightweight accessory pulleys and such.

wow...god i hope that was sarcastic...otherwise it might be the dumbest thing I have ever heard...you might get a .00025 hp gain from that...

did it on mustang gt and gained power on the dyno. air entering the engine is cooler because it is not surrounded by hot coolant. im not saying i have, or would, do it to my car.

i understand the idea behind it but in practice it is not useful enough to warrant most people from bothering...maybe if you race for a living...but seriously you are talking about a small amount of coolant in a ring around the throttle body...the air is passing by so fast at that point it isn't going to make a massive temperature gain....and certainly not a gain of 10HP! I would say at the most you might get 1/2 to 1 hp ...if that

minuscule surface for heat transfer + incredibly small residence time = virtually insignificant heating/cooling effect.

This "mod" has been beaten to death. In fact, someone on a mazda6 forum did the math for the 2.3l MZR, and even under extremely optimistic conditions, and with generous assumptions, you're looking at a fraction of 1hp.

The situation is even more futile on a turbocharged and intercooled engine.

werd, there is more than a couple threads discussing this
