i saw something on ebay about diverting the coolant away from the throttle body.....thus making the coolant cooler and giving more horsepower. is there any truth to this?

 

there is somewhat of a truth to it but its gains are too little to even acount for.

first consider that when at speed/ accelerating, the air is moving thru the TB pretty quickly. and the TB itself is only a fraction of the total lenght of pipe the air flows thru. so its effect on warming the air is very very minimal.

the true reason for runing coolent thru the TB is to warm up the TB so taht in cold weather like below 32*F water vapor wont freeze to the Throtle plate. cause the faster the air goes and also the manifold being under vaccum, the temp could suddenly fall from pressure change. so keeping the TB warm will prevent this.

that all being said. there are benifits from having it.

if you do a lot of work on the engine, it makes it easy to remove your TB later and not have to worry about dripping coolent and later bleading the system of air.

if you are like me, i look for every little thing that can help. and since this cant hurt me. ( live in a warm climate rarely goes below 50 here!) i figured i might as well while i was porting the TB and intake manifolds

if you chose to do it, make sure you dont spend too much on those kits. cause if you have a 3100 or 3400 you can just remove the coolent hose and route it around the TB and if you have a 3800 series engine, you can buy a plug or seal up the gasket area and acomplish the same results.

 

thanx! thats a big help!
