how many of you guys are running turbo timers?

[jt15833]

thinking about picking up a turbo timer from a friend of mine for $20, just wondering how many of you guys are running them. think itll save my ca t25 that much? also you guys think itd increase chance of theft at all even with ebrake kill switch, maybe the bling factor

[nnkfws333]

I'm running one and you can never be too safe in my opinion.

[rico05]

Agreed. Every turbo car needs a timer and a boost gauge before any other modifications (well, and if in a swap situation, an uprated fuel pump, but i digress) My HKS E-01 was my first purchase post swap.

[Loofee95SE]

agree: I have the Defi VSD Boost/Timer..and it's never to safe when it come to investment. C

Water-cooled turbos have no benefit from a turbo timer. The point of the turbo timer is to let cooler oil circulate through the turbo to cool the CHRA housing. Water cooled turbos do this inherently so having a turbo timer is redundant. I am not saying it totally useless but it's definitely not a necessity and will only have a marginal effect on turbo life. I would be more concerned with using clean oil and not overboosting.

But once the car is off, no coolant or oil is cirrculated regardless, and the oil that is lubracating the bearings sits there, as the hot turbo cooks it.

Right, but who goes balls to the wall straight to shutting the car off? 30 seconds of lower speed driving is more than enough time for the temps to come down.

Exactly. I've never run a TT.

I do when im late for work or school, lol and hey its only 20$ get it!

I'm with C-rad on this one. Unless you are beating on it, and then just shut it off, the TT isn't necessary on a water cooled CHRA .

As far as the water not circulating, that's not true at all. If you've hooked the lines up correctly to the back of the intake manifold, the coolant is moved through the CHRA via convection.

To explain, if you look at the coolant lines, you'll notice that one comes up from the bottom and the other exits from the top, heading towards the back of the intake manifold. When you turn off the car, the coolant in the CHRA heats up. The heated coolant rises up inside the coolant line, up towards the manifold. As it moves out of the CHRA, lower temperature coolant moves into the CHRA behind it. This lower temperature coolant draws heat away from the CHRA, which causes it to heat, rising up the tube away from the CHRA towards the manifold. This process repeats until the CHRA is the same temp as the rest of the coolant in the system. Also, at some point, the coolant reaches the back of the manifold. This is important for a couple of reasons. First is that the back of the manifold is the high point in the system and is where all bleeding should be done from. For a convection current to work well, you need it to be able to rise as much as possible. As it reaches the manifold, the exit is a coolant line that runs straight down. The reason for this is that after the motor is shut off, the manifold acts as a heat sink to cool the heated coolant coming from the CHRA so that it can drop back down, feeding the cycle of coolant for the CHRA.

If that's not clear I can draw a picture :biggrin

Need Pics

But yeah, i don't think i know anyone who doesn't run a turbo timer over here..

This was my first purchase when i got the car, Apexi pen type, and it has never let me down.. and i love the little extras like battery oltage, and a/f ratio

[tyrannix]

that works for people that *didnt* cut the manifold out of the coolant cycle (to help reduce intake temps)

the convection wont work as great if the coolant return is plumbed back into that collector tube (or if you are using one of those snazzerific CPC plenums, those dont rise up like the stock one, even if you do use the manifold, its not higher)

so if you are running a mostly stock CA, then you could get away with not running one, otherwise, why risk it?

[burnout 180]

I run a HKS Turbo timer and haven't had any problems and I go balls to the wall straight to shutting my car off all the time.

I say just buy one it won't hurt, come on all the cool kids are doing it.

Hows that for peer pressure. lol

Yeah, they race their cars so fast in fast and furious, and 2 fast 2 furious, and thiers didn't blow up, i guess they don't do much.

[biosehnsucht]

I have a 180SX owner's manual around someplace (unfortunately it was before I had truely gotten my wings on Yahoo Japan and I ended up w/ a SR 180SX one, when I wanted a 89 one to match my car lol, but hey it was like 500 yen) and it mentions to not shut off the car immediately, and has a little table listing how long to idle it i.e. 1 or 2 minutes, but thats as far as it goes

[slownslurious]

yeah my friend has a protege and I was reading the mazda speed section and it says if you boost hard or drive for long periods of time to let it idle for 2-5 minutes depending....

[rico05]

I dobut that there is any way that the coolant could move around in a pressurized system w/o being pumped. And I got WOT to work all the time, and shut her down. Usually, my TT wants my car to run ~1 minute, but one more than one occasion, I have had it run more than 3 minutes (3 minutes is the highest user set time you can do on an HKS TT FYI) Sorry, but I just can't buy the idea of not running one.

[slownslurious]

well, hows this: my clip had 88,000 km on it, no turbo timer, and my turbo had 0 shaft play and you could BLOW on the turbine to spine the wheel.

I seriously doubt whoever drove the car in japan was letting it idle for 5 mins before shutting it down.

[Ghost_silvia]

But the person who had your car could have been a grandma that drove 10 miles a day and never really warmed it up. Or it could have been a guy who knew to let the car sit after running. You never know.

[burnout 180]

Or maybe they took the turbo timer off of it before they sold it to you. I know of no clips that come with a turbo timer on them because they take them off.Those JMD dudes are smart like that bro.

My HKS TT can be set as high as 9:59. It's the HKS Type-I.

[Akihisa]

I always let mine sit for a couple minutes before turning off. It helps.

[sdtouge]

for 100$ i would rather sit in my car and let it cool down for a few monutes.

Well, I got mine free when I bought my exhaust and BOV for my DSM from my local rice shop.

[240 Trainee]

Yea, I wouldn't pay full price for one, but you can get one off ebay/ friend/ something, and alittle extra help never hurt anything.

Odd. My E-01 can only go to 3 minutes. I don't know if it matters, but I bought it from an eBay seller in Japan, and it came with Japanese instructions.

[sdtouge]

lol at a local rice shop

yeah in my opinoin, its like paying someone to pick your nose.why give away 100$ when you can do it yourself just as good!
