Yes, performing the throttle body coolant bypass will net a very small gain. You will never feel it and it might not even show up on the dyno.
Coolant being circulated through the throttle body is to warm it! It's not to cool it. This prevents icing of the throttle body.
When the vehicle is running the throttle body is actually cooled by incoming air. The throttle body doesn't actuallly get warm because it's mounted on a plastic intake manifold which insulates it from engine heat. Being insulated and having cold are passing through it all the time keeps it cool. However, having hot coolant running through it does warm the incoming air charge. Performing the bypass is helpful in keeping the incoming air cooler. You may get slightly more horsepower, but you may also get slightly less fuel mileage.
I have performed that mod on my Formula many years ago and will probably do it to my Camry once I get down south again. |
looks like i won't be doing this too =P I'm more concerned about gas right now than ever... last i checked 91 octane is at 3.80 *squint*
