When I build boost in 5th gear or so, the hose just pops off the throttle body! i've tried 4 diff clamps now and nothing works... what can be the cause of it??? its like sudden, just started about 2 months ago.

 

clean the tb and hose then spray some hairspray in the hose where it contacts the tb and reassemble. GL

 

you should get some t-bolt clamps

 

t bolts are not needed, but def help.
what pipes you have? I realized with my Injen that the upper pipe needed to be settled a certain way or it would pop off

 

do this spary in side of the coupler with brake clean. then take a rag and whipe it till its dry.. slip it back on get some t bolt clamps if u dont have them already. this will make it stick and should come off then..

 

I generally use carb cleaner on throttle body and also on a clean rag and wipe out the inside of upper I/C hose really good. Then wipe one last time with carb cleaner soaked rag and quickly install hose to T/B. Wait a few minutes then tighten clamp. Once the carb cleaner evaporates it turns your hose into a very tacky rubber and should hold very well. Every one that I have tried this method on has held up,all the way to 35 psi.

 

i got my tb vbanded and put a vband on the end of the uicp, now i never hafta worry about this problem ever... its worth the money for no hassles..

 

yeah its just the grease on the coupler to tb surface. clean them both thoroughly

 

You ought to post a picture if you can, that sounds interesting.

I'm always half ways waiting for that pop and power loss at WOT

hasn't happened since I wedged that battery (OEM) into it a little, but I'd still like to see your set up.

 

very smart man!!!!!!

Anywho, a properly built charge pipe setup wont ever blow off. Like I siad, with a 2 piece setup like the Injen, if there is any kind of slight bind or anything you risk this happening.
Any custom ones I had done, I did the turbo side in one piece and the intake side in one piece and use the cheap @$$ $1 clamps and never once had one blow off.

Make sure the couplers are not greezy though too as stated above.

 

like mentioned above, clean it. i use alcohol, then scuff it with sandpaper. And has held up to 26psi

 

The hairspray works just fine.

Carb cleaner making the rubber tacky...cause its dissolving the rubber and breaking it down. Sure it may work, but I wouldnt do this to my car.

 

Also make sure to loosen all the clamps on the pipes and align them properly so there is no stress on the pipes. If they want to pull in any wierd direction before tightening they arent aligned properly. Once aligned properly get some good quality clamps and use a 1/4 in rachet with proper sized socket to tighten them. DO NOT USE A SCREWDRIVER! Then you will have no problems.

 

i wanna see this, put pics up

 

Clean properly, try T-bolt clamps (see picture)
