i know turbo timers help cool the turbo, that must mean it will give the turbo a longer life correct me if im wrong, how important is a bov im ganna try and keep this car as long as possible and if theis parts will help the turbo last im down for buying them considering they are like a 100 bucks a pop, please give me some info i went from a 85 12a to a 87 tII

turbo timer is just a time saver. instead of sitting in your car for a min with it running. you can pull the key out and it will turn itself off. but you can't arm the stock alarm (if you have one) untill it shuts off so.... basicly you should always let the car idle for a min or so before turning it off.

a BOV won't make anything last longer unless you are making high boost/power. the stock one is fine.

With a water cooled turbo, a turbo timer is really not necessary. In normal driving, even with some use of boost, the core temp does not get to levels that are likely to cause the oil to boil and leave deposits. You just don't push the turbo for the last mile of driving and it'll be sweet. Air cooled turbos are a different story altogether, and a turbo timer probably isn't a bad idea as the core (and the oil in in) gets quite hot.
One reason turbo timers aren't actually that effective is very little cooling of anything takes place when the car is stationary due to the absence of any airflow. The fan only needs to move enough air to remove the heat from an idling engine, which is stuff all.
This isn't just my opinion; I made the decision not to use one after reading alot of stuff and talking to people who've been around turbos a while and have info on testing of core and oil temps. Note this is not the advice you'll get from anyone who actually sells turbo timers! At the end of the day it's up to you, and a timer won't actually hurt your engine.
BTW, you should never rev an engine and then shut it off staight away. The turbo will have been spun up, and you've just killed its oil supply! This will quickly fry bearings. Always let it idle for a few seconds to let the turbo drop to it's idle speed.
The BOV does not need to be replaced unless it leaks, which won't be untill you're running quite decent boost. Aftermarket open-vented BOV's are for one thing only: the noise. They have no effect on performance. Yet no one calls them rice...

Your last comment is spot-on

Anyway, for our turbos, here is a trick that works surprisingly well: for the last minute or two of your drive to where you're going, POP THE HOOD This actually works !!! Of course you should be going at maximum 10-15mph (ideal when you're coming home), and the air rush from the open hood drops the temperatures DRAMATICALLY !!!!

Try it, it works !!!

If you are overly cautious like me get em', if not then don't. I refer to my turbo timer as just a overpriced volt-meter. But hey it does save a little time, and b/t/w I love cool little gadgets like that, thats probably the biggest reason I bought mine.

Stepdaddy

thanx, ill wait untill i have money to blow, i do like the looks of them and another gadge cant hurt, in reference to the bov i sure do love the sound but if not nesesary i probaby wont get one

Sure, they don't have anything to do with performance, but it does add a margin of safety to prevent compressor surge to the turbo.&nbsp The stock CBV is pretty tiny - I put money it can't vent all the boost when you're pushing over 10psi of boost.&nbsp I installed my GReddy Type-S BOV to prevent the turbo from killing itself from compressor surge; I have run boost anywhere from 14-17psi - the GReddy is insurance that I don't kill the turbo from unwanted compressor surge.

You're entitled to your opinions, but aftermarket BOV's do have their place.

my turbo timmer is great for doing quick stuff like running into the bank. set the the timer for the max 10 mins. lock door, come back a couple mins later and don't have to restart I use it more for that then turning the car off

NZConvertible

It doesn't need to vent all the boost, just enough pressure to prevent surge. Even a Ø15 hole will vent 1 bar very quickly. I'm not saying you're wrong necessarily, I just don't think the engineering matches up to the marketing hype, and a lot of poeple spend a lot of money when they don't need to.

Yeah, making the manufactures lots of money!

Something I forgot to mention about turbo timers. Since they're wired in parallel with the ignition switch, they make it very easy to hotwire your car. This is straight from a car thief!

Something I didn't mention...turbo timers are a WASTE of money.

Its pretty cool to park somewhere and leave your car while its still running. Everyone thinks your crazy, until the car magically shuts off. Ooooh! Aaaah!

Its funny I have both of these gadgets, but could care less about them (because they don't do much for performance). Yet every time I drive my car, people are most interested in the cool noise of the BOV, and that my car shuts off by its self. Just shows how easily amused people are.

Brian_TII

Uhh... I don't see how it really makes it any easier... Basically the theif could get to those same wires just as easily with out the turbo timer. Maybe it might help point out which wires are which... but the turbo timer harness plugs right into the factory harness.... so I can't really see how it makes it THAT much easier...

Turbo Timer: Leave your car running,and some fool is gonna jump his *** in it. Don't be in too much of a rush that you can't sit there for a minute.

BOV: Aftermarket BOV's are overkill and don't help performance at all. I had a SARD valve and it made me go really rich every time it vented. Just killed throttle response. Every time i shifted, I had to wait about a secod or two before i could accelerate again. I've gone back to the stock valve and **** is cool again.

NZConvertible

You're obviously using a nice expensive TT. Cheaper ones with two wires you solder into the ignition wiring and then stick in a nice accessible place allow you to hotwire the car in half the time with minimal damage to the car.

Stepdaddy

so you cant accel untill its done "blowing off"

Erik

wow...so you can't arm the automatic locks if the car is running?

i've had a new GReddy turbo timer...just never installed it...maybe now i won't...

Scott 89t2

as i posted before, the doors lock, but the stock alarm won't turn on. you have to close the door after the car shuts off for it to arm.

NZConvertible

Yep, that air that's been vented has been measured by the AFM so its fuel gets injected even through it ain't there; instant rich mixture. A recirculating BOV doesn't have this prob, but then you won't hear it much.
