Is this from GReddy Ti???

 

It's the Apexi N1 Noir

 

ok

 

Sounds pretty much like stock, almost the same size muffler tip too.

 

sounds like stock? there's no difference? If you heard GReddy Ti, not even close to its sound?

 

Using an MBC is user preference really. Some companies such as Buschur and Dynoflash like to use MBC's and some dont such as vishnu. Using an MBC could pose potential problems due to the fact that they are holding a static boost pressure through the rpm's and even up into the higher rpm range. If the car is not tuned properly and you are running a static boost pressure, the potential for problems exists. Using the stock boost solenoid provides safety in the sense that it allows the boost be raised but as the rpm's climb the boost will slowly start to fall off. This helps prevent catastrophic failures that a static boost pressure might cause. The motor can handle increased boost but it can only go so far and once again if it is not tuned correctly bad things could happen.

 

Um, boost tapers with an MBC just like it does when controlled by the ECU. It is no different...

MBCs are nowhere near as dangerous as they are being made to sound in this thread. They're only as dangerous as the person who sets the boost. The difference is that using the stock solenoid allows the ECU to lower the boost in the case of a major failure or issue, but that is extremely rare. It also is only something the IX ECU is known to do. The VIII ECU just does it if it goes into limp mode. There are thousands of cars running MBCs, because they are simple and reliable. I personally prefer to have direct control over my boost at all times for all situations. There is no such control if the flash controls boost, so it comes down to personal preference.

 

ill keep that in mind...thanks

 

I know someone who has one, everytime he pulls up to my house it sounds like there's a helicopter outside. I joke him about it all the time.

Yup, probably about as close to stock as you can get. Cops in va can be a$$'s sometimes when it comes to loud exhausts.

 

Exactly

 

Notice I said everything will be ok if the car is tuned properly. Just wanted to make that clear

 

Doesn't matter that much if it's tuned properly - that's not really relevant. Without a tune, you're just richy rich, so having increased boost isn't a worry. The only issue would be if you're running aggressive boost AND lean AFRs AND aggressive timing, but what tuner does that? That's another rare case scenario...

 

It is completely relevant to say "if the car is tuned properly". I see no problem with saying that since if you increase the boost your are changing something major.

 

I hate to be the one to ask this, but insnt it safer to run an EBC than a MBC? I know that they have more dynamic configuration capabilities. I just wanted to get an opinion.

 

can somebody please give my a short explanation of whats an MBC and EBC? I just want to understand what you guys are talking about.


Thanks
