Default Need some help and some ideas on Boost controllers and turbo timers

Ive done the search, but the words "boost" and "turbo" are too common to search for :P

So what Im looking for is a reason to get a boost controller. I know why I should have a timer to let the car cool down before it shuts off, and I run the car for about a minute before I do that anyway.

But is it smart to get a boost controller if I plan on doing basic mods to the car? IE turbo back exhaust and a cpu reflash? If so, what would you guys recommend I look at? Ease of installation? And where have you guys mounted them to either make them look factory or hidden? Anyone have an pics?

As for the TT, there are pros and cons. I have a GReddy, but it's just as easy to sit in the car for a minute or two. If I had to do it over, I wouldn't put one in.

The boost controller need really depends on what direction you are headed with your mods/EM. On my '02 I had a TBE, STi injectors, UP, VF34 with AP EM and I did not switch boost control. When I switched to the UTEC on the same car, I used the stock UTEC controller, because it was tuned that way.

My current set up is an Ecutek with a UTEC and I use a Turbosmart MBC. The reason for the MBC is that's the way the tuner set it up. MBC are extremely easy to install, but a boost gauge is a necessity.

It boils down to what mods you add and what EM you elect to run (and of course the type of tune).

The turbo timer isnt really needed on a stock turbo as they are oil and water cooled. Just dont beat on it and immediately shut it off and your fine.

As for the boost controller, like in post 2 it depends on the direction your taking with your car. I did one, but only because I am externally gated so it was a neccessity for my car to work right.

Turbo timer is pointless on our cars because our turbos are not oil cooled.

Boost controller will blow your motor up pretty quick on an '07 STI without engine management and a custom tune. Your stock ECU is very touchy and runs a lot leaner than the previous models.

Agree with V. The answer should be NO and NO to both.

Don't get a turbo timer. You don't even have to let the car sit when you're done.

You can can get a boost controller, even though they are unnecessary, but you would need a tune for it.

Dont buy anything till you do a bit more learning about your car. I dont like to see people spend their hard earned cash on pointless parts, especially parts that could damage their vehicle. Trust me the time you spend leaving it alone and learning about it will pay off BIG TIME. Even if its just a month or two. Read the tech forums. Read them a LOT. The newbie forum is ok, but you will really pick up the knowledge in the tech forums.

On the 2 mods you asked about...
Turbo timers havent been needed for over a decade on 99% of factory turbo cars, as almost all of them have water cooled turbos.

And boost controllers without engine management, heck doing much other than washing and waxing a stock 07 STI without engine managment is dangerous (Im not kidding, they are blowing up scary often BONE STOCK!)
You havent been able to safely run a boost controller on a WRX since 04 and on an STI since 06. Unless of course you have engine management tuned for it.

You will gain more from engine managmenet than you would just a boost controller anyway. A lot more.

It is painfully obvious that you have not searched at all. There is a FAQ that comes up before you need to scroll down to see the posts. But it does come after the new thread button so it is not your fault.

The best thing to mod is the driver. Get in some track or autocross time.

The STi is pretty well potent in stock form. Get to know the car well and the upgrades will make sense when you do them ... but in general the way mods "should" go is

- make it stop
- make it corner
- make it go

.... but the STI's pretty good for all those already .... so I'd really suggest getting out and finding the car's limits first. And driving on the street, you are really not going to be able to do that all too well
