Guys, your talking to GORBS88, the INVENTOR of the turbo timer for the sole purpose to slow the turbo down...
But in all seriousness when your turn your car off your at a stop correct? The turbo is not spinning a hundrend and fifty thousand revolutions per minute at idle. period. It takes a couple of seconds to stop spinning at idle when you shut it off...Some people never seize to amaze me.
A couple seconds to stop spinning????????? ARE you nuts? You must have no experience at all with turbos do you? Have you actually checked this??? I have personally timed a BB turbo and from IDLE it takes one full minute for it to stop. THIS is on a BB turbo and a bushing turbo is around half the time. 30 seconds isnt a couple. THIS is from experience by the way. Mabe you should go outside and conduct a little experiment on your car BEFORE you open your mouth.
Is there a special way to remove the existing studs on the head to replace them so that they don't break or am I in the clear since I already got the nuts loose. Vise Grips maybe? Plan on installing this beauty this weekend and want to know if its going to be an all day project or an all weekend project.
I've never timed it, but lets say you are correct. How is a turbo timer going to stop that from happening? Most people I know let there car idle before shutting it off, no in fact everybody I know does that.
took my 16g 6 seconds to come to a complete stop from idle..
Thats weird, ALL of my turbos have taken WAY longer then that.
My big 16G takes even less then his does and my turbo only has about 10,000 miles of driving with no more than 10psi thrown at it, I think that you just need to admit that a turbo timer isn't to let your turbo spin down. And besides what sense does that make? Why would you care if your turbo is spinning for another 15 seconds after you stop?
Theres no load on the bearings or bushings so it's just free spinning to a stop. So if your turbo timer is to let the car run and slow down the turbo then what sense does it make if it takes you turbo 30 seconds to slow down after you turn your car off from idle? Come on, it's for getting the hot oil out of the center of the turbo.

My point is that when the car is shut off there is NO more oil presure, so if you didnt let the car idle for long enough then the turbo will be spinning TOO long WITHOUT oil presure. PRETTY SIMPLE.
Getting the hot oil out of the center??? What do you think it's doin just sitting in there.?????? It's called oil presure which is circulating oil through that turbo real fast.
OK so first you say that your turbo continues to spin for another 30 seconds after you shut your car off from an idle, so how does letting your car idle for another minute after turning the key off help slow the turbo down faster, since YOU say that your turbo runs for 30 seconds after shutting off from an idle no matter what, your contradicting yourself.

Im not contradicting myself, I AM saying that if you let the car idle for a minute or 2 it WILL bring the turbo down to the slowest speed possible before shutting it off.
If you read what i am saying you will realize that as long as you idle the car the turbo WILL be slowed. And if you didnt idle the car after pulling off the freeway then the turbo MAY be spinning abit faster then you would want. THAT is what i am saying.
The 30 second example was when the car has been idled, if it hadnt been idled then it MAY be longer. READ what i am saying.
There are millions of oil cooled turbos on the road that have not had a turbo timer and have been around since the 80's. By the grace of god the turbos still live today somehow!
The TT is NOT for letting the rotating assembly slow down. It's not, and there's nothing you or anyone else can say to make it that way. Well, it might be if you like to shut your car down at redline under full boost. If that's the way you are parking, you have bigger problems.
The TT is designed to allow the turbo to cool down to avoid the oil cooking (coking, coke is the burnt oil stuff that's all up in it). If your car hasn't been under a load when you park it, then there is no reason to run the turbo timer at all, it's a waste of gas. If you can't help but drag race at every stoplight before your work, you would likely want it to sit and idle for a while. Furthermore, if you have a 30 mile commute, you could race for the first 20, and cruise for the last 10, pull into your parking spot, shut your car off and never have to worry.
It is (IMHO) for sure a waste of gas on a water cooled housing because the WC housings don't get hot enough to coke the oil. That's from a few sources I've read, I'm welcome to other opinions on the subject though.
Also, modern oil! It's come a long way from the 70's and early 80's when coking was such a big problem. Modern oil is less likely to break down, and or coke up the bearings.
So it's really up to you, and how you drive your car, and if you're willing to waste that gas, or kill your turbo. Nobody can say when, or even IF your turbo will die. Maybe see how bad your mileage goes down by letting your car run for 1.5minutes after every time it's started and see if a TT isn't more expensive in gas and equipment than rebuilding a turbo every two years! Personally, I would not run one, only because I drive conservatively before I get to where I'm going (yeah right ) and if I don't, I'm careful to let my car idle for a while afterward.
Yeah, lock nuts, two nuts tightened together on a stud. Get some PB blaster on that thing beforehand though. WD40 doesn't cut it for me anymore.

i tried to keep my mouth shut but gorbs,,,,,,,,,,,,,, now you are talking about pulling off the freeway and shutting off. you were not saying that in your first statement.
gorbs..., you see, alot of people including myself are new to dsms, and we try to learn off of other people. we dont want some out of this world explanation for why, but would rather someone with firsthand knowledge of the situation try to help us out. we (i) do not want to take some advice on something that will cost us (me) tons of money to fix.
so please try to refrain from commenting on something that you do not know for a fact, then cant admit when you are wrong

Sorry man, but this is incorrect as well. If a turbo is fed oil from the head, it's not from windage, but from an oil galley (the same one that feeds the lifters). It IS pressurized, but it is of lower pressure than many other parts of the engine. This is why guys use the head for a source of oil for their turbo. Turbos are pressure fed and gravity drained.Moreso with a feed from the head, in the windage area of the head wich !? *ISN'T PRESSURIZED*! It's gravity fed,
