hey. i'm really interested in getting the HKS turbo timer.
not because i need it to keep my car running, but because i want something that does 1/4 mile times, 0-60 etc...

is there something better out there that i should consider? thanks.

oh, i know the Japanese spec type-1 is in km, will it work on our US spec cars? or do i have to buy the US spec. i don't want black!

 

I have been hearing good reviews about the new G-Tech for its accuracy. It's probably cheaper than the HKS TT and certainly easier to use and install.

 

hm.. who company makes G-Tech. i've never heard of it.

 

the G-Tech is the bomb.. its about 1-2 tenths slower then an actual 1/4 run, but its dead on in its measurements

I used to take a 1st gen G-tech I had to the strip with me and run it when I would make a pass, it was a constant .1 second slower, but it was exact every time

perfect for actually timing your mods

 

my freind had one he said it sucked it was off alot

 

the G-tech is very touchy to how you set it up. If you do not do it exactly how it needs to be, it wont be worth more then spit.

when its set up correctly, its on the money every time

 

The new G-tech, version 2 I think, uses GPS to get numbers and is supposed to be extremely accurate. I think it retails for about 200 or so.

 

 

i know about the cooling system.

is this why my car keep growling @ idle? it's crazy. goes on and off. sounds like a beast. haha....

 

Hey, i've heard here/there about its cooling capabilities, but your little bit there explained it well. But my concern is not the coolant, its the oil line/lubricated surfaces. Anywhere oil is left to sit and boil in a superhot turbo it can, won't it??? isn't that why we use a TT to let it idle long enough to cool it down so the oil doesn't coke?

sorry to escaflowne for jackin your thread, but we're onto somethin good here, eh...

 

The bearing in the turbo has the coolant all around it to take away the heat.

This is a subaru specific diagram:

Thanks, all of that info put together helps my brain understand that the "thermal siphon" actually works. The only question I have left is about the oil passages. The engineer gal stated that the oil only flows on the "cool" side of the turbo, but from the cutaway pic, it appears to flow around both ends of the shaft, on both the hot and cold sides. Wouldn't you still have a problem with heating up the oil on the exhaust side?

I already have a TT, so I'm not trying to figure out whether or not to buy one, i just wanna know if it really does anything worthwhile... I still think its a valid component for keeping my engine healthy in a couple of situations:

long freeway drive to work, then a 20 second drive from the offramp to where i park the car. That means i have sustained high EGT's (600-750 degrees C) for about 40 minutes, then I drive down a couple city streets for less than half-a-minute, and then shut the car off.

Any time I run hard and then wanna go park it at home. (i have a great "canyon" run about 15 seconds drive from my house)

again, thanks for your time dude, lots of great info. Bennie

 

it's cool.
all i wanted to know was if the j=spec turbo timer would work accurately on my wrx.
i don't mind having my acceleration times in KM, i just accuracy.
