has anybody actually done this and noticed any differences? just curious...

 

I tried it, did not do anything. Only advantage I see is the elimination of a hose. If it did not need TB warming, it would't be there.

 

i tried it...didn't notice anything bad from happening. I know alot of people have done it and noticed an improvement.

the only thing i noticed was that the throttle body is easier to take off...which is the main reason why i did it. i would probably not recommend it for winter driving though.

 

What material did you use to do it, what size, where did you get it, and what size hose clamps will i NEED?

 

i read the tech article but i didn't really find it very helpful. you can check it out here

 

i used heater hose to bypass it. i noticed it at higher temps. like around 210 degrees i still had good acceleration and response. oh and i live in south texas which never freezes. if the throttle body has to warm up it does with the heat transfer from the plenum.

 

I'll give you guys a scenario that got me looking into this. My one Honda sportbike came with two 48mm carbs. After looking at the service manual I noticed coolant was run through the carb bodies. It looked like a spaghetti factory. Figured I would clean it up and save a lot of potential leaks in the future. On a 90 degree day I would be sitting at a light and it would simply stop running. Sometimes it would start right up, other times it cranked a bit to get going. Found out it was icing at the idle air passage. This is because of the large difference in air pressure. My brother in law is a FAA certified flight instructor and he told me a carb can ice up sitting on the runway on a 90 degree day. I realize that we are talking about fuel inj but the principle holds true. The idle air passages in the throttle body are small and the same scenario can occur. I would agree that it is probably an uncommon occurence but the possibility still exists. That is why they heat up the throttle body in the area of the idle air control. Hope this has some info as to why they do it.

 

But I figure with the underhood temps that are cars get, it probably would'nt happen due to heat transfer from the manifold, and plenum. So in places in warm climates I don't think it would freeze over. Has anyone ever had this happen? Just curious.
