Doesn't PVC emit chlorine gas when it gets hot?

--Matt

 

Due to warranty concerns for some owners, has anyone looked into the possibility of inserting a thin sleeve into the stock part? Or at least making some sort of mod to it.

 

Hi
I bought the part.
I remembered a pdf file shows the diagrams to install it, but I can't find it.
Where was it?
Thanks

 

YES IT DOES MATT!! you would be correct. also what happens when you do it this way.... the pvc is not happy with the amount of heat in the intake after the turbo and before the cooler. it actually softens. so when you clamp the hoses down and go have fun,the pressure of the clamps actually starts to crimp the pvc hose from the heat. now the clamp is loose. you check and think, ut oh, gotta tighten the clamps not thinking that the pvc pipe is shrinking inside and starting to choke off the flow rate. then you drive again. the clamp can only go so far and so can the pvc pipe. now it gets to the point it blows off even under factory boost pressures. now,it starves the engine for air and un-burnt fuel burns in the hot side of the turbo. now the turbo has the ability to look like the end of lit a cigarette when taking a good hard puff. I wouldnt know this.... never did it . i would not recommend it at all. theres actually one made with shipping for 40 bucks. i just put it on. vip precision or something like that from arizona.

 

I didn't use any instructions, I just followed the walkthroughs on the forums. It is really easy to do. 2 bolts, 4 hose clamps. Takes about 15 minutes. There is a hole in the lower crossmember where you can get to the lower clamp on the IC hose that I saw in a video after I did it

 

yeah vip has one for 40$

VIP states:
We do not recommend this on 2011+ N18 motors

Anyone know why?

 

I emailed vip to ask why they don't recommend the muffler delete on the intercooler pipe for the N18 motor.

 

Glad I found this. It's a lot cheaper than the tubes from Forge or Alta.

 

Any luck on the CM install?

Thanks!

Yep, installed it in April or May. There's a thread with pictures in the Countryman drive train modifications forum.

 

Thanks!

 

Did this mod the other day with a free piece of aluminum pipe. I haven't noticed any considerable change. But it is kinda nice knowing there's a free flowing pipe there now instead of a muffler

 

Just ordered mine

 

I have the above item installed on my 2010 Clubman S, didn't notice any real gains except for a heavier foot on the gas . In my opinion (with absolutely no scientific data to prove it), i believe it helps the engine breathe better and that's it. For less than 50$ it's a hell of a better deal than those 150-280$ intercooler muffler delete pipes advertised elsewhere.

 

Installed fit nicely. Nice tone...

 

I have looked through most of this thread and keep seeing people post that there are no dyno results. Alta claims their muffler delete hose gives 10 whp and 10 wtq. In fact, they go a bit further and state the following:

"The before and after show how the Hot Side boost tube makes a noticeable change in horsepower. After installation, we saw an increase in boost of about 1.5psi higher, which this carried across the entire RPM band. Except above 5700, where the ECU didn't like seeing this extra boost."

So that sounds like there should be some real gains. Is it just marketing or is it real? The first person testimonials are so contradictory....

 

I did finally get a hold of them to ask. They say there is a slight rubbing with one of the coolant hoses. I can't really see how thats even a issue since the stock pipe is well.. a pipe..

I plan to mod mine with a section of straight aluminum pipe.

wont cause any engine lights. most you'll notice is the sound difference while driving. as for spooling faster..... no, spooling faster comes from differential pressure from one side of the turbine to the other. bigger down pipe or cat deletes will do that part just fine. of course you will not run any noticeably faster with out a tune. i just finished a full custom exhaust and a few other parts. I now have to call evolve for the tune they are now offering. unless you put tunes on these cars, any mods are pretty much useless,unless its in the suspension or you pony up for a ecu tune to make the mods effective.

 

Short answer - who knows.
Interestingly, Alta used to have a dyno chart on "hot side boost tube" page that claimed torque increase below 5K RPM, and torque drop vs. stock above 5K. So you gained some in low/mid-RPM range, and you lost some in high-RPM range. The took credit for the former, and disclaimed the latter. Now the dyno chart is gone.

I did install the Alta pipe in conjunction with their big-*** intercooler (aka FMIC). Those two plus a K&N (VIP) intake made a HUGE difference in preventing heat soak over multiple autoX runs. Most of the benefit likely came from the FMIC, though that's just a conjecture.

Pre-upgrade, my fastest times were posted during the first 2 runs and all the subsequent runs were a frustrating waste of time and tires. After I stopped blaming myself for over-driving the car and upgraded the FMIC, the times keep on dropping throughout the day. Either that, or I suddenly learned to drive properly after 20 years of trying

Hey ELSENORDAVE, how is it going with the Pre-Intercooler Cooling Pipe - 2.0? Are there any gains or is it mostly just "tone" as you mentioned on 11/23/2013?

 

Let us know how it fits - without a mounting tab, the metal fins could rub and rattle inside the tight confines of the engine bay.

Of all the places to attempt cooling the intake airflow, hiding a cooler inside the engine bay on the exhaust side of the engine is likely not the most effective location. In front of the nose of the car, with maximum access to the airflow is optimal, which where the the stock or aftermarket inter-cooler is mounted.
While this piece it can not hurt anything (unless exhaust side engine bay temps exceed those of airflow inside the pipe), and the price point is attractive. However, if you really want to improve airflow cooling - consider a proper over-sized aftermarket FMIC!

YMMV,

'08 MCS with K&N (VIP) CAI, Alta airflow tubes, and FMIC (among other goodies).

 

It fits like a glove, slight pain in the *** to put in (depending on whether you put it in from the bottom or the top of the engine). Slightly more aggressive tone, and I believe not having a baffled inside surface does help with smoother airflow into the fmic. For $50 you can't go wrong and no there is not any rubbing from this, i have shaken the pipe parts it's attached too violently many times to test how it moves and it barely moves at all, i don't think you have to worry about rubbing.

 

Someday I'll get a FMIC
Gains would be hard to quantify scientifically but yes it feels a little more responsive!

Mine fits like a smedium

 

Wonder what it would be like if the entire hot side discharge pipe was made exactly like our pre-intercooler pipes..would be interesting haha
