Info: Does bypassing the throttle body's coolant hoses make a difference?

	I know this isn't nearly as fancy as all the s/c talk but: A while back people were talking about picking up a couple hp by disconnecting the coolant lines from the throttle body. They would essentially link the two hoses together and just bypass the TB. Someone, (Anthony D. I believe0 picked up a couple of hp on the dyno for free. I think he eventually went to running ice water on thru there for drags. Anyone on the list done this? Any detrimental effects? I know it isn't a huge gain but if its free, I am all for it. The theorizing was that VW did this to help keep the throttle butterfly from freezing perhaps. Thoughts Ryun Needs a vr6

	I have had mine bypassed for a good while now. I didn't do it for performance, I tried a different throttle body that didn't have the coolant flowing through it. The throttle body didn't work out, but I was lazy and never re-connected the coolant hoses. No problems here, although I don't notice a difference. Peter J.

	[...] I am slightly confused....why would vw run coolant lines along the tb? for cold weather, and for running cold? is there a valve that shuts the flow of coolant once the motor reaches operating temp? because this would heat up the tb and the air, making the car more fuel efficent. perhaps a good mod for the summer months? -- aaron... ------ Aaron J.

	It's there to keep the TB from freezing in the winter months...I ran back to back dyno runs with it in place and then bypassed...difference wasn't big enough to measure on the dyno... A few others on this list have found the same thing...in theory it would help when the weather's hot, but the gain was so small it couldn't be measured...
