installing uicp will i notice any difference?

[wcpierson]

saturday im going to be installing a dejon tool uicp and was just wondering if im going to notice and difference in my car

 

[ndsti]

Yes, you will notice a small difference. It will help with boost and spool time. It gets rid of some of the restrictions the stock piping has, makes the air flow smoothly.

 

[kmoore]

Yes, you most certainly will. You will notice your spool-up time will decrease and your throttle response will be very more uh... responsive. If you are taking HP and Torque numbers, then you probably won't see a huge increase in those categories. But, overall you will just notice the car as a whole will be a lot more "peppyier"

 

[xioca]

You will most likely be able to hear your turbo spool up more and your blow off valve may be a little louder.

I recently installed an UICP and a 2G exhaust manifold on my car and it made the car feel more crisp. It just felt better whenever I accelerated.

 

[wcpierson]

just a month ago i had a 2g manifold and o2 housing installed so this uicp is my next step i am definitly looking forward the a more smooth throttle response and a quicker spool...ill let you guys know what happens

 

[JayRolla]

You actually wont feel much. This has been brought up a lot and I talked through email with Buschur racing about this topic. I found a link to a dyno slip that netted 0 hp results with the UICP upgrade. I asked them for the link but they didnt know where it was but he said it was correct.

I installed one and all you get is maybe crisper throttle response and better off boost drivabilty.

That's odd. Project car magazine claimed they gained around 15 hp with their SMIC piping on 1g dsm. Car was apparently dynoed as I remember. Never did like that magazine, talk down on dsm's and praise little honduhs.

 

[PieEyedPiper]

I'm with JayRolla on this one, no significant change.

 

[LordZed]

I think it depends on what your running too. In my case, I had the JDM RS motor breathing through a stock 1g rubber IC and the RS elbow had to be swapped to the Talons teny tiny elbow. I could just feel it's limitations. When I put the 2.5 hard IC up top and a 2.5 elbow, it was like a lightswitch had been thrown. Not monumental power uppage, but like they said, better spool, throttle response that seems to be at least 50% better on roll on acceleration, and a great turbo sound whistling up boost under acceleration.

 

[wcpierson]

did the install today....spool is more responsive and a LOT louder....i couldnt believe how small the 1g tb elbow was compared to the one supplied with the dejon tool uicp....love the whistle sound by the way. Thanks for all the input before i attempted this i appreciate it.

Boost Leak Test!!!!

Boost Leak Test!!!!

why do you say i should do a boost leak test? im still boosting fine and holding 15psi with some boost creep?

Nothing that involves the intake tract can be considered complete until a leak test was followed. Just because your boost gauge is showing full spool doesn't guarrentee no leaks, it could mean the turbo is working overtime. Where are you tapping for boost reference for your TurboXS mbc?

Honestly, just do one. Pulling the TB elbow off requires you to pull the TB bolts out which frees up two gaskets that can leak badly. Also, my first Dejon UICP had a leak at the TB flange weld and I had to return it for another. You honestly won't know until you do the test. You'll be running a bit rich which loses you some power. It's something you should try to do every so often, as a lot of the sealing materials degrade with time and exposure to heat.

Think of it this way: you just spent a fair amount of cash to get a bit more hp. Fixing boost leaks could add that much more if you're leaking. If you're not, it's good to know.

Where's my wisemen entry fee?

















Congrats Mack!!

 

[wcpierson]

i dont know exactly how my mbc is hooked up my friend did it for me one day while i was at work since he has the same one on his tsi...and my boost gauge is tapped in just as it says on vfaq.com. I was wondering if my turbo was working harder since it is louder now and i dont want to work it hard at all this is my daily driver. Ill go over everything tomorrow but i dont have a boost leak tester of my own so i post on njdsm to see if anyone could help me out asap...please OLDMAN let me know what you suggest i do

I feel like I need to pull and rebuild my motor to earn my keep. Too bad Bessy (backup vehicle) is snowed in at the moment (not to mention there's nothing currently wrong with the motor).

But thanks!

First thing I would suggest is to use proper capitalization and punctuation so I don't feel obligated to warn you. Seriously......

Go find your mbc and tell me where both lines run to. I can help you with your leak test if you can't find anyone to help you on njdsm.

 

[91tsi2wd]

noob question, but where do you guys have your mbc's spliced? I have one from my bov line and one from the wg actuator...is this ok? turboxs mbc. or do i want just the outlet nipple and wg actuator...

 

[oldman]

You want to source your boost reference from either the compressor housing or LICP, not the BOV line. This is what I posted before on why not to use the BOV line.

1. BOV line was previously thought to be better and more accurate because it's the pressure the engine sees when in reality it doesn't matter because boost gauge is already measuring manifold pressure regardless where you reference your MBC.

2. Long route vs short route, increased chance of boost spike.

3. Turbo protection. In a case of developed boost leaks in your intake tract, tapping BOV line will result in turbo spinning out of control while boost gauge till maintains full boost. Where as a compressor source will open wategate sooner while registering pressure drop on your boost gauge.

4. This is the most important one. Tapping your BOV line will result in a slightly opened BOV under WOT because of pressure bleed through the MBC's wastegate pressure relief hole. The situation gets worse when using a bleeder type like the TurboXS units because it's also a vacuum leak which can lead to idle surge as well as compressor surge.

 

[91tsi2wd]

oh wow thank you! I guess I have some rerouting to do tomorrow! on a sidenote, will the 2 way connector that i removed from the fps to install my three way t for my boost gauge fit in the now cut bov line? j/w so I don't have to spend any more money than I have to... thank you!

 

[oldman]

It's best to replace the entire line but the connector should be ok as a temporary solution as long as it fits tightly, accurate boost reference to the BOV line is crucial for your turbo.

 

[wcpierson]

My mbc is hooked up like this. The bottom connector is running to the wastegate and the side connector is running to the compressor outlet elbow. Oldman how far from Northern NJ is Dayton? I would really like someone with experience to help me with this.

Good, just making sure you weren't tapping the BOV line like 91tsi2wd.

There are plenty of capable people on njdsm. Dayton is about 10 min down RT. 1 south from New Brunswick. PM me your number and I'll give you specific direction.
