Dude, I totally can't believe you just did that.

 

 

burn up? what's going to cause it to burn up? the heat radiating from the alternator?

it's to prevent the valve from frosting/sticking in extreme weather.

 

I think he's playing with you.

You can laugh now...you're not the butt of some epic pwnage.

I'm about to go out into the garage and do the same thing. I'm a little bit of an idiot too, so if we're wrong they can laugh at us together.

I just wonder how much of a difference it makes.


I'm sure that once everything is up to operating temps, you can assume that the throttle body is atleast 50-60 degrees above ambient. It actually has a decent sized area that is convecting heat to the intake charge, but is small compared to the intercooler. also, the rest of the intake manifold is heated by the head anyhow, and has a MUCH greater internal area.

I'm sure every little bit helps though, and for the ease of routing a hose, it should be done. Well, atleast if you live in parts of Texas where it only freezes once a year.

 

I love insecurities. I own a few myself.

 

I'm pretty sure I picked up at least 50hp.

 

Drag racers used to rant about this. The real reason other than de-icing (which never happens) is to keep the PCV vapors liquid enough, otherwise the throttle butterfly can get gunked up. THere's an absolutely negligible difference from removing the warming loop, you won't even get a degree of difference at any airflow where you'd make power.

I kept reading idiocy on many forums about insulating pipes or removing that bypass. I tried it on my old Mitusbishi Mirage with a thermocouple screwed into the intake manifold. I lost one degree at idle (highest heating potential) removing it. Related to that was that I put a steel section in the intake and heated it to 1800deg F with a MAPP torch. 5 degrees at idle, thats it.

Now, on the other hand, application of the extremes of that theory is true. A compressor outlet to charge cooler pipe can reject HUGE amounts of heat until the pipe reaches the outlet temperature, but the temperature changes are much more extreme than some 180F coolant touching a few square inches of air.
