Hi guys,

I know that it might sound silly but I would like to know why so many people use turbo timers like the GReddy. What are they useful for?

Additionally, do you guys think that a K&N replacement air box filter will be good enough for a stage 1 turbo upgrade?

Thanks a lot for all your help

 

Turbo timers are used to cool off the engine/turbo after driving. Best after hard driving, but it lessens the chance of your turbo having a short life. If you don't have a TT, let your car run for at least 3 minutes upon parking/standing, in order to allow everything to cool itself down.

 

More accuratley, just follow the cooldown procedures in your owners manual. The three minutes is only recommended after a hard run followed by parking. If you drive normally the last two minutes or so, no cool down is required.

 

I use a K&N filter along with my Stage 1 and am 100% satisfied. It doesn't attract "attention" when I take the car in for service/oil changes either....

Unless you're super impatient, just let the car idle like it says in the book. I always pop my hood after I drive home, it cools down a little quicker and I can check the oil and OCC......

 

So, do you adjust the "timing" with **** on the TT?
How does it cool off the engine quicker?

You guys are great and thanks for your responses.

The hood being open cools it off faster as more air is coming into the engine compartment than would if the hood was tightly closed. The scoop is less functional at a standstill than at speed.

I usually just sit wherever I'm parked and let it idle and cool down for a bit anyhow, instead of what the book says. I'll sit an extra 3 minutes anyways. Doesn't hurt. I'd rather have the TT though so that I could park the car let it cool and then do as I please, since sometimes I, as everyone else at times is, am in a hurry.

 

The timer is not to cool the engine! The turbo can reach rpms uppward of 10,000 rpm, plus the exhaust heat, the only way to cool it at the bearings is the engine oil. If you run hard and shut off, the heat at the bearings start to cook off the oil and break down the bearings. I have heard of red hot exhuast pipes after a long hard run, so think about it. The bearings in the turbo just can't take that kind of heat without a coolant. That is also why you should run a good quality, turbo certified oil, and let the oil cool the turbo down by running the engine for a few minutes. PEACE

 

Yeah I've seen red hot exhaust pipes....I always wanted to know if they'd glow through the scoop in the power bulge at night. That'd be sweet

 

That's another reason only to use synthetic oil.........

 

Full Syn here....no clumapge. My car will never see ghetto gas or ghetto oil to cut costs. [>:]
