Is it possible to connect the air-bypass valve directly to the throttle body, instead of cutting the pipe? Actually, I know its possible, but does it work the same? Anybody know?

I'm no expert, but I wouldn't put the bypass valve up that high cause U'd never want water to go that high. The Valve dones't totally prevent water from going up the pipe, but most of it will be sucked out theoretically. But do u want that much water that close to the throttle body and have the Valve do it's job at that point? Probably not.

I would think that the purpose of the bypass valve is to prevent a vacuum from occuring when the end of the tube is under water. If this is the case then it shouldn't matter where you put it on the tube as long as the bypass valve isn't under water too.

Try sucking through a straw with a hole in it. It doesn't matter where the hole is you still will not get water up the straw.

I can't find the post itself, but somone on the TL board did that and it didn't work out to well. Bottom line is that it's designed to be put about mid-way on the intake per the directions that come with it. I wish I could find the topic about this, but I can't seem to locate it. Anyway, I would change it ASAP.....

I think I read somewhere (Possibly from AEM) that if you put the Bypass at the T/B, you could potentially lose power..

Jake

Thats weird. I wonder why you would lose power. Does the valve cause turblence or suck in hot air?

If the valve is working correctly it should be doing nothing except being a tube unless the end gets plugged.

I would expect turbulance at the location of the bypass valve..

I would be concerned that under WOT (Wide Open Throttle), there would be so much vacuum generated that close to the throttle it might cause the bypass to open and draw in air that isn’t filtered as efficiently as if it went through the K&N down below.

Just a guess of course, but why risk it for aesthetics ?

Aw c'mon... cut the damn thing! The inside of the bypass valve has a different characteristic than the rest of the tube. I think if it were up high it would spoil the air flow at the "curve".

Just admit it, the XEPHYR design is the BEST !!!!!

It wasnt done for aesthetics, I was handed the CAI and the Bypass and it didnt come with any directions. I figured that it would be stupid for it to go behind the Filter so it has to go at the top, again thats lame but where else is it going to go.

I would never have thought that you had to cut the $200 dollar exhaust pipe into two pieces. :P

I'm going to fix it this week.

Anyways, As far as the vacuum sucking the valve open under WOT. There is actually very little vacum at WOT, also why would it make a difference where it is in the pipe? Its solid.

And the losing power comment? I dont see how....
