throttle body bypass

[zmerun]

anyone out there using the bypass for the throttle body? any problems?

When I added the blower and had TB off I did the singel hose bypass. It makes taking TB off/on easier but other then that it is a waste of $$$$$. If you don't need to remove TB often the forget it. But it won't hurt anything if you do it

I had one on my 01 and now have it on the 03 and all is well. Although I'm not really sure of the benefits, it must have some effect if the air is kept cooler.

The theory is, it helps prevent throttle body heat soak. It will not give you anymore horsepower. It might keep you from losing horsepower do to heat soak.
It might give you drive-ability problems do to icing if you drive in Cold climates.

I have one on my car

Save your money for real mods.

I think my shorty antenna gave me more hp than this coolant bypass mod. It doesn't show up on the dyno, but I'm sure it has to cut down on aerodynamic drag compared to the stock whip antenna.

I cost me $3.00 for some hose, fitting and two clamps.

Not worth it. Not even a good idea imo. You can get throttlebody icing even in 75 degree ambient temps.

Here's why: The velocity of the intake air increases as it passes through the throttlebody. This causes a pressure drop (Bernoulli's Principle) As the pressure decreases due to the increased velocity atmospheric moisture can condense onto the throttlebody forming ice, causing a reduction in power.

I can't speak with data but I always thought that the only purpose for that item was to put a few bucks in the wallet of the vendor that sold it. Marketing 101. Create it and then convince people they need it.

I've heard that before also.

AND POSSIBLE STICKING OF THE THROTTLE

Read and heed No Doubt's post again!!

if this is a potential problem wouldn't the cold air intakes exacerbate this? After all, systems like the vortex rammer pressurize and force the air in.

NO! The throttle body is heated as the engine's coolant passes through it. This heat eliminates the possibility of icing...no matter how cold the incoming air is. The heated throttle body will ALWAYS be warmer than the intake air. If the coolant bypasses the throttle body and atmospheric conditions (temperature, humidity, barometric pressure, etc.) are just right, ice can and WILL form at ambient temeratures well above freezing. Since the bypass has NEVER been shown to increase HP, why would anyone take the chance of having ice bind up the works in the throttle body?
