Soo.... this I understand... but there is also a boost bypass that relieves excess or UNEEEDED pressure to make the desired boost pressure.

If say you have a boost leak or your I/C cracked. The first pressure sensor sees 22.5 psi in my case... but the 2nd sensor only sees 17... it's going to make the bypass send the extra pressure instead of relieving it.

Wow you guys are dense...


I am going through this problem right now. because of a cracked intercooler. The turbo is SCREAMING it's ass off... and only making 16 psi.... WHY because pressure is being leaked before the second pressure sensor.

But on the grand scale of things... EVERY SINGLE intercooler available for this car is WAY oversized for the K04. It doesn't not flow enough air to warrant a 600+ cu/in intercooler. Or 800 for the HAHN for that matter.

It's just added strain on the turbo.

 

No one wants to understand this.



:shifty:

Imma PM j00

 

Its kinda like preaching to a brick wall... it hears you but doesn't comprehend a damn word you say!


Morgan from Synapse is taking care of mine... he has been very helpful. Although the intercooler is a pinch to big... the core flows really well and has a really high fin/in.

Hopefully he did a better welding job on this one though!

 

id be up for a group buy for this in a bout a month. This is the last part i need before im going to get a tune.

 

meh some of the guys on here are running low 12's on stock fmic so i guess it flows just fine

just look in the drag list section

 

The stock I/C is very good... but when high boost applications (ie: custom tunes and boost controllers) the plastic end tanks can break after a period of time.

 

im trying to make sense of this. if there is a leak in the system then the entire system would fall to the same amount pressure since its all connected as one.

 

pressure changes, thats why people have BOV's and BPV's, it vents unused air, or recirculates it. The boost is not constantly "on." You have to build air and pressurize the system. The more volume you have in the system, the more air it will take to fill it. Therefore the turbo will have to push more air to meet the same volumetric pressure on a larger intercooled system.

 

If it's too big oh well. It will work just great with my 3076r when it goes on

 

all obvious stuff... still doesnt answer my question, or statement

 

Correct, You should see a drop is boost.

 

I installed my synapse intercooler yesturday and had to cut a **** ton out of the bumper. The bumper is still tight up against the ic but oh well. I notice a little vibration in the lower rpms since i installed the intercooler. Im guessing that this is because the stock one had rubber mounts and this one has a metal mounting tab. I have also noticed a little more lag than before, im guessing this is because of the pressure drop due to the bigger core.

 

yeah, that is about par for the course with it. It cools really well, only down side is it's soo big that it takes it a bit longer to fill the core.

Give it some time... if you are custom tuned adjust your DAL table to compensate that... and you won't notice it anymore.

I will use my car as an example...

I have a crack in my cold side endtank... the pressure sensor before the intercooler is seeing the 22.5psi. But the sensor in the cold side pipe is seeing say 17psi. The car is going to compensate that 5 psi drop by allowing more boost to be pushed into the intercooler.

Hence why it sucks having to MAP sensors in this car. Believe me my car sounds like it has a GT30r on it with a screamer pipe.

 

awesome.....is that little vibration normal then?

Also my bumper doesnt fit as good as it used to....its off a little on one side....not tooo bad tho. I couldnt cut anymore off of it

 

yeah mine is the same... the passenger side on mine is tight... the drivers side is not. I don't have any vibration to report... but I have had so many issues with my intercooler that would be the least of my problems.

but I will say... Morgan has been very helpful and is taking care of me. Great customer service with him and Synapse.

 

really.....what issues have you had with it

 

cracks in my endtanks... I have the old version though. Which morgan is sending me the new version which he says will have no more issues like this.

 

yeah i noticed my endtanks are reinforced.....in that case, be prepared to take more off the inside of your bumper...lol..It adds atleast 1/4 of an inch to the thickness

 

Keep it going guys. I like hearing the problems/things that might be wrong. I am learning.

 

does your intercooler stick below the bumper like a half an inch

 

yes it does... it's because it's an 8" core...

 

WTF is sticks out from under??? That's no good.

 

yes it mounts to the same spot as factory... it's actually just 1/2" under the lip... but not as low as the black wind thingie under the car. I'm on SSC springs and have NEVER scraped the intercooler!

 

uh oh.....i think you just jynxed yourself.....lol

 

LOL nah I'm to careful for that. But I will state this....

On the stock Intercooler with +80* outside temps.... IAT2's were 118-125* at the end of a 3rd gear pull.

With the Synapse and 80-85* outside temps.... IAT2's were at a max of 93* at the end of a 1/4 mile run!
