Did any of you guys bypass the coolant lines that go to the throttle body?

 

sure, but what are you really asking?

Do you need tips on how to do it?
Do you want confirmation that it works?

More info is needed from you!
Dont forget about the 5 W's. Who, what, when, where, why and How.

 

<p>No one does it.. I wouldn't worry about it. You should have just texted me haha</p>

 

Actually I didn't need to know about it. This post was just an experiment (and or bet) as to who would be the first to reply to it. I knew it was going to be one of two acurazine members.

 

you texted Joe, didnt you?

 

<p>I always answer haha</p><p>It's my nature to be helpful. Crabman only cares about statistics of his Azine Account!</p><p>EDIT** and to be fair... you posted in the performance section. Let's be honest there are like 5 performance CU2's on this forum haha. You had a small of pool to choose from.</p>

 

pshhh.

I did it..

 

make that 6..... my car does perform.... not very fast....but it performs...

 

Used those for turbo and wastegate cooling, SUCKERS GAVE ME 25 WHP at 8500 RPM

 

Does bypassing it really make a noticeable difference? And what about during the winter, won't that shit just get stuck open?

 

I have it for 3 years, no other big mods on motor. Dont think its for more hp. But cooler air is never wrong. No problems in German winters

 

I'm not risking it, we had days that were -14F last year

 

I've never heard of someone's tb butterfly getting stuck before. This mod does lower iat temps. The coolant going through the tb keeps the tb around 180-200+ during operation. It's kind of like air going through a intercooler except it has the opposite effect.
I have seen someone install a small ball valve inline of the coolant hose to turn flow on/off.
I would imagine that a cai would really benefit with a coolant bypass.

 

I just thought of something here.
Even if these coolant lines are hooked up, wouldnt your throttle plate freeze up if it wanted to anyways?? The throttle body only warms up as the engine warms up so when you start your motor after sitting in freezing temps over night during the winter it wouldnt make a difference if the lines are hooked up or not.

 

Do it!!

 

 

Yeah but as the motor warms up the tbody would also warm up. If the lines aren't hooked up it'll never warm up.

So say it is frozen when you start your car, well.. it'll just stay frozen then.

 

The tb is surrounded by Heat sources to warm up.

 

 

you do know that the TB is under a high pressure spring and a motor that snaps it into place right? It almost chopped my finger while I was cleaning it because I got tired of pushing on it to clean out the carbon.

I drove my car in -20 degree last winter in WV. The throttle body didn't freeze shut. The only way it would freeze shut was if you got water into the actuator and it froze over night. There was a video about this controversy a while back on k20a about the coolant bypass. The consensus was that it was safe if you did it right and plugged up those holes.

TB freeing would probably happen easier in cars with cable throttle. There isn't a motor on it to force that mofo back into place.

 

hmm alright. So it probably won't freeze.

But still, what is the actual benefit to doing the coolant bypass? Is there any definitive dyno proof that it gives a HP increase?

It seems to me like the air would be moving much too fast to actually be heated up by the TB. But i dunno.

 

there no benefit unless you have other supporting mods. The air will still head up unless you have a therm barrier in placed like those p2r gasket. My manifold during wot run and everything upstream feels luke warm to the touch after a WOT run. That will be the only time you will see benefits. Lower IAT = more timing --> more power

for daily driving in traffic everything will heatsoak so it won't matter.

Thanks for the explanation!
