Overboosting issues? Im i taking it too far?

[Demi]

Okay so here is the list of things i have ordered already. (not installed yet)
Injen CIA
Corksport 80mm downpipe
Corksport 80mm exhaust
(non that it applies but) stiffer rear engine mount and shifter bushings

Now, next week i plan to order,
HKS SSQ blowoff valve
3.5 core intercooler.
and hopefully a turbo manifold shortly there after.

Do i need to grab a XEDE and get it tuned before i drive it? I know it would help power production but shouldnt bolt on parts work without a tune?

 

[MS3ICA]

it not good for the engine, be careful florring it at lower speeds in 3rd thru 6th. cpe standback or xede will fix the issue not to mention give tons extra power

 

[Rotus8]

Forget the BOV. It will be nothing but trouble with nothing in return except funny noises.

you forgot the 3rd piece to that exhaust system. you need a test pipe/mid pipe.

Also, why do you want another turbo manifold? wasted money imo unless you go big turbo!

Also, what rotus said, no need for an aftermarket bov unless you plan on turning up the boost or have a custom application. save that $200+ and put it towards wheels/tires/suspension!

Call me a tard if you want but its just for the sound....yep just the sound. GOD i love it. As for the turbo manifold that (as i understand it) gives you quicker spool on the turbo. But surely with just the intake downpipe and exhaust i wont NEED a tune. and i thought the down pipe was the mid pipe, just with a cat on it. My understanding is that a test pipe and a downpipe are the same except that the test pipe deletes the cat.

 

[javanc]

The downpipe is the part that comes right off the turbo. It then connects to the midpipe which can be replaced by a race/test pipe. This test pipe as made by now 3 companies deletes cat. #2. The afore mentioned downpipe contains cat #1 and is the source of the most power gains. If you go with a true TBE you will end up replacing all piping from the turbo outlet to the tailpipe, this is the best breathing configuration to have.

A turbo manifold connects directly to the block and is in between the engine and the turbo. If the stock cast manifold were poorly flowing i would consider changing it. But it deals with a high amount of heat and is a royal pain in the butt to change out. Unless going with a turbo that has a different bolt configuration than stock the aftermarket mani. is a bit overboard.

 

[6262MS3]

Yeah I'd only change the turbo manifold if I were swapping in a bigger or more responsive turbo.

 

[Demi]

fair enough, and that might come later but WILL i experience problems with the blot on parts OTHER than the manifold?

You're a tard!

lol I know i know, but i cant help it! That BOV gives me a chubby! i mean sweet lord listen to it! http://www.youtube.com/watch?v=ouYs9bTq2Mo
Sweet god.

a blow off valve is a good thing to upgrade, your freeing up alot of power with all that s*** and your turbo will spool fsater and higher peak. you may or may not run into problems with your plastic valve right away but its a good upgrade that you will eventually need. mine sounds nicer vta http://www.youtube.com/watch?v=-OumVZIRA0I

What is not good for the engine? Everything he is doing the stock ECM can accomodate.

 

[clos561]

spiking the turbo. some guys are experiencing this and they get power drop for a second untill the boost level reaches normal pressure. someone is hitting 21.5 or something and the car stops him untill the boost reaches 18-

 

[Ryz]

Mine has been spiking to 21+ forever. I put my boost guage on after about a month of having the car and only had the CAI on.

I love blow-off valves, don't get me wrong. I used an RFL on my last car.

But no way is it better for the car than a bypass valve! How? When you are dumping the air off to atmosphere your turbo HAS to replace all that air when you get back onto the shift. If you bypass it then the air is rerouted down back into the compressor and it allows the compressor/turbo to freewheel and when you get back on the boost the air is already there.
Not to mention that on a mass airflow equipped vehicle the air is already counted by the ECM and the correct amount of fuel is ready for injection into it. Without a tuning solution to correct this excess fuel you may be looking at stalling and other issues like engine surge, etc.

Ahh the HKS sounds like a consistent sneeze. Nothing but WRXs and STIs have them around here, I'll stick with my Turbosmart.

A BOV or BPV is a personal preferance (sp)............ Plain and simple. Now if you are boosting to a point to where the stock valve can't hold the pressure , then yes an upgrade is needed, but just because of the upgrades, doesn't mean you should be running more boost. you may see more boost spikes, but not more overall boost. Computer still commands to see X amount of psi, the turbo reacts faster and the computer has a momment where it plays catch up, then it should MAINTAIN that boost pressure.

If its not then you have a boost control issue. Boost Spikes on the other hand are different. They too can also harm the engine, if not controlled.

if you want the sound and the flash by all means buy one, but is it required? NO!

Also you should run your setup as a Bypass not VTA, but if you don't mind the stumble here and there, and possible little back fire in the exhasut, then run it VTA. its true you are dumping metered air, but once you go WOT again the MAF doesn't care, it just measures the air going IN.

Not really. He will definitely be overboosting/fuel cut with that setup. He will need a boost controller at a minimum or one of the EMS's.

 

[Demi]

So can anyone recommend me a boost controller? Ive never used one before how hard are they to setup? Can i just set them to the factory boost levels for each gear?

 

[shamrock]

This may sound stupid, but if YOU wanted to be safe and never run into boost spike/creep, just dont get a BOV. Would this be true
