Whats the deal with turbo timers?


Recommended Posts

i think it really depends how you drive the car...if you thrash it, i would say yes. it just lets the turbo cool down. but its not that neccessary to have one. you could always just sit in the car for like 30 seconds then switch off. its really up to the individual.

Provided you take it easy in the last 5 minutes of driving before you turn the car off, then a timer isn't really needed.

If it was, it would be installed by the factory.

Just don't thrash the car before you turn it off.

joel, you set the turbo timer for the length of time you want the engine to run on idle, so that the engine doesnt go straight from being hot-as to suddenly cool, which damages the internals cause of the sudden temp drop. i think you're thinking about boost controllers mate.

IMO turbo timer are overkill for street use. For everyday use, if you slow down and take it gently the last few minutes before arriving at your destination, you won't really need turbo timer that much.

Only when you take your car to the track regularly, it will be quite handy when you have to lock the car and walk away between lap sessions.

My understanding of the need for cool down is to prevent coking/carbonising of the oil in the turbo bearings, which can occur if you shutdown while everything is still hot. If you keep it running on idle for a short while (or driving low load as Sky031 suggested), then the turbo has a chance to cool down, lots of fresh oil is circulated through the bearings and the oil left sitting there when you shutdown won't carbonise. Carbonising of the oil will stuff your bearings.

All a turbo-timer does for you is automate the cool down, so you don't have to sit there. Personally, I drive low load and/or sit there for a minute or two or keep it running while I get my bag out of the boot and stuff.

As for locking and leaving at a track day - who the hell is going to pinch it?!! I left it running with bonnet up and doors open ....

Cheers.:)

Dunno where u normally go for track days, but I've seen certain tracks with open entrance to public (no security standing there) and anyone can just walk in and pinch anything from the pits when no one's looking... Some other tracks are good as they have one or two controlled entrance in/out of the pit area.

it is illegal in vic to have a turbo timer as it violates adr standards. your engine must not run when the keys are removed, this is an adr rule and a turbo timer bypasses this rule completely hence it being illegal. the purpose of it as stated is to let the engine run, while the engine is running the turbo is still spinning and has oil and water running through its water/oil lines. as soon as you kill power to the engine those lines stop flowing so the turbo halts and is most likely very hot.

with the use of the turbo timer it gets a chance to idle for a minute or two

most manauls for turbo cars suggest this and the r33 at least did have a factory turbo timer option its on the left of the sterring column down about 30cms, usually its a blank panel but on some r33s its a switch with short and long and the turbo symbol. i prefer the fact to leave it idle for a minute or two as it gives a chance for all the temps and shit (if high) to settle, at least a tiny bit

I recently read an editors reply from speed magizine from a similar question.

He said that they are a waste of money that are often incorrectly installed which leads to the fuel pump still pumping petrol out if you have a major accident. They exponse ignition wires that makes the time to steal your car dramatically less. He went on to say that anyone that doesn't take it easy 5 minutes before parking a their car doesn't deserve to have a turbo car.

Sorry, mate. I am living in my own little world and ignoring the realities of life in places less fortunate than Perth. If you ever get the chance to cross the Nullarbor, you would enjoy a track day at Wanneroo or Collie, I am sure.

Meanwhile, life way out West seems to have other benefits compared to good ol' Victoria, judging from comments in this and other threads about their application of the ADRs. The disparity between states for relatively straightforward rules seems farcical. If the ADRs said that all cars had to have a round steering wheel with two to four spokes covered in a non-slip grip, I reckon the state rules would be something like:

NSW: RTA would say cars had to have steering wheels and cops would defect you based on your age and who's in the car.

Vic: You could have either two or four spokes or three spokes with a leather grip, but not two or four spokes with leather grip, unless it was a factory option.

WA: You could fit an aftermarket steering wheel as long as it was not smaller than the factory wheel, but cops would still defect you if you were not white caucasian or if they were having a hard time with their missus.

QLD: You could fit an aftermarket steering wheel, as long as it was yellow suede to match the seats.

SA: Any steering wheels are fine, as long as they say "Holden" in the middle.

NT: Whatever looks cool when your fingers are gripping it really tight!

Cheers.

    • What are the torque specs for those 6 bolts on the retainer plate and 4 oil pan bolts? I'm currently tackling this job during an auto to manual conversion... I thought this would a 5 minute job! 
    • Tryna decide if I should get a skirt coating on my cp 2618 forged pistons that im about to order. Anyone have first hand experience with a forged RB with coated or non coated piston skirts? Is it worth it and does it make much difference? And for people who went with 2618 pistons with no skirt coating how long has your engine lasted? The engine is an rb25/30 and main concern is  that It will be a daily car and will probably see a fair bit of short distance driving, have been told by my machine shop and my tuner that generally a forged engine lasts around 40,000kms before needing a rebuild. Would a skirt coating make much of a difference? cheers 
    • From now on read it as minus 5 and minus 7 instead of dash, and you're correct...
    • Opened up the cluster to inspect the gauge itself for signs of damage and it looks good. Got curious since that needle doesn't go back to a "neutral" position by itself (it stays in the same position when ignition is off. so I manually moved it to 1/2. Connected it back, turned on the ignition and the needle started moving up! Not sure what's up with that but before that the needle was way down below empty like fully south west. There's always a chance that the needle moved slightly the first time I tried and I didn't notice because of how slowly it moves and how far it was from the markings. I don't know if the current needle position is accurate so I'll fill it up and see where that brings it. I guess I'll try to adjust it manually if it doesn't get to F. Looks like the needle position is relative and not absolute? Thanks all for your help and patience!
