PWM chargepipe - BMW 3-Series (E90 E92) Forum

Adamteee · 10-07-2012, 07:04 AM

I did a little search but didn't see anything, my vishnu chargepipe keeps popping off. It's from the reducer silicon adapter on the charge pipe side. I had a 07 e90, and switched to an 09 e92. Never had a problem on the e90, but can't seem to keep it on the new car. Every WOT pull, pops right off. I've messed with it for days and can't seem to keep it on! Any suggestions?

Do you have version 1 or version 2 of the silicon reducer? version 2 is a little longer. While I have yet to install the kit, it came with version 1 and I had them send me the updated part.

I'd assume it was version one, I think I was one of the first to get the pwm kit. That would explain, always wondered why the tight fit!

I ordered early as well. Quite a few changes here and there:

1) 4 small changes: This is the thread where the slightly longer one was announced: http://www.e90post.com/forums/showth...&highlight=pwm

2) New pump with higher speed, and better connectors: http://www.e90post.com/forums/showth...&highlight=pwm

3) PNP Harness update: http://www.e90post.com/forums/showth...&highlight=pwm

I got the longer silicon coupler and the PNP harness. No desire to buy the new pump until I get some use out of the original.

Have you tried cleaning the pipe and coupler with solvent?

Any traces of oil residue on the surfaces might promote slippage.

Just go to the store and get a tube of silicone. Put it on the reducer, go that it sticks to the chargepipe and stops slipping. I had the same issue until I did this. Boosting to 18 psi now, no issues.

I'll have to try the silicone, I tried cleaning it.
Looks like they changed a bit. My previous 335 had a failure in the line and the car went up in flames, so I've been out the bmw scene a while.

Try hairspray. It will slide on easy when initially applied and then it'll dry an stay on.

I had the same issue last couple of weeks and finally got it the fix...Bought a 3.25" silicone hump coupler from ebay (OBX brand) and 2 tbolts clamps from mandrel something (ebay too)..I cleaned up all the surface with brake cleaner and applied a light film of silicone gasket maker on the inside of the silicone hump coupler. All in all cost me less than $30 and so far I've been doing datalogs and seeing consistent 18 - 18.9 psi
