VRSF Charge Pipe Keeps Popping Off

Has anyone else had this issue? I installed it about a month ago, and it has popped off the throttle body twice now. I'm running MHD stage 1+ (about 15 psi of boost). The factory C clip doesn't seem like the greatest solution. I wish it was just a hose clamp...

Am I doing something wrong? What can I do to prevent this from happening again?

Make sure the charge pipe is 100% fully seated with the throttle body..... Avoid little gaps
Also give the c-clip a little squeeze with your fingers before putting it on, to mke sure it clamps things together when you insert it back.

Make sure the C clip is in the correct orientation as in not backwards and it should be seated all the way down on the chargepipe before you push it on to the throttle body.

Take a flat head screw driver or something similar and physically push into the clip all around it so that you see it go into the groove on the throttle body. It may be in the groove on one side but not on the other side.

I will try that.

I believe I have it correct. The tabs face away from the throttle body, correct?

I felt around with my fingers and it seemed to be fully seated...

I was having the same issue. The C-Clip doesnt seem to be able hang with the MHD tune. I even had Tiago send me a replacement thinking maybe something was defective and the same thing happened. I attached my fix. silicone and some hose clamps.

Is there an oring like the factory charge pipes ?

If there is put a little lubricant on it, you may be rolling the gasket causing to not seat 100%

The C clip option is actually preferred.

When using those style charge pipes, especially with VRSF CP you need to use the supplied O ring.

Also the orientation of the clip is important as well ensuring the charge pipe is seated fully.

It takes a bit of a push sometimes and you need to hear the *click*.

If you didn't want a C clip style CP, ETS does make one but again all the other companies go with C clip style for a reason.

I had a similar issue with mine. I took everything off. Wiped it down. Gave the c clip a good couple squeezes and put everything back together. Seemed to do the trick.

I mean my fix is temporary but it gets the job done. I tried to the lube it didnt work and the C-Clip was on the correct way. The only thing that changed between it working and not working was the MHD tune.

You might check the slot in your throttle body and see if the sharp edges have been broken/dulled. A loose ring, that has slipped off several times, can round off the slot and make it a lot easier to fail again. The damage can start when your factory charge pipe failed the first time.

I know that my ring disappears within the charge pipe, it engages deep into the throttle body slot and has never come off.

it did come with an o ring. I think I put a little grease on it, but can't remember for sure.

I will try this. I guess I will have to take the airbox back off because it is pretty tough to do much with it in place.

I actually cleaned my TB area and used a little bit of sand paper on the mating surface just to make sure the surface was smooth and clean. It also helped put the pipe on as it was very tight. Every car is different at the TB it seems between corrosion and dirt and debris that can affect the install.

Gotcha. Yea I probably would have done something similar if I still had that problem.

Okay, I just re-installed it. I squeezed it this time before putting the clip on. Unlike last time I had the clip fully seated on the charge pipe before I pushed it onto the throttle body. It took a lot of force. THe last two times I installed it, I had the clip pulled up and then when pushing it on it snapped into place. Not sure if that makes a difference.

I included two pics. One of how I found it after taking the air box off, and the second after I re-installed it. Let me know if everything looks right.

Looks better than my ER, hope you have the o ring. Shoudnt force the cp w c clip, that goes on later. Change vacuum lines.

Looks ok but you probably damaged the c clip or the aluminium throttle body by forcing a chargepipe on with the c clip already pushed into locking place.

Why do you say that? One of the posters above suggested I do it that way, and after looking at the design I don't see why it would be a problem. The throttle body lip is ramped where the c clip and CP slide on so I don't see why anything would get damaged. Anyone else have an opinion on this?

I think it's fine to push the cp on with the clip down in the 'installed' position. The only way I think damage would have occurred is from the cp popping off and possibly taking a little material off of the TB.

Pictures look good. Just make sure its tight and you cannot wiggle it with moderate force. As long as it is tight and not moving, you're good to go!

We generally recommend squeezing the chargepipe onto the TB and then applying the clip. Also some clips tend to wear or bend after being removed so many times so it may be a good idea to either squeeze it a bit to shorten the width or purchase a new one.

The OEM C-clip is 10000x better than a coupler and clamp on this application. The OEM TB doesn't have a bead meaning you have no way of creating a guaranteed seal on the TB side.
