i was wondering if when i drive my FD and i dont use the turbos what so ever, if i should still let the car have a cool down period for the turbos?

 

Drive your car easy for the last minute or two before you get to your destination, and shut it off right away when you get there. Letting it sit at idle only makes the engine heat up.

 

If your not getting on boost then you'll be ok to shut it off after you park.
Otherwise, if you want your turbos to make it for the long haul, and your running it hard or just got done drag racing, you should let it idle for atleast 90 seconds, to prevent oil coking.

 

dont boost for the last 2 minutes, then wait like 30 seconds after you park. Turbo timers are a waste of money.

oh yea..and get synthetic oil, much better on turbos.

 

Ok, since this has been bugging me for months now -- how in the hell are you supposed to drive without boosting? I've taken it to mean that you are not boosting high or engaging the secondary.

Seriously, it's very difficult to not get boost even in 2nd gear, but in 3rd, the slightest touch on the throttle gets me a few psi of boost at almost any rpm.

So, I will reiterate what the others have said with the caveat that "no boosting" means don't hit 10 psi or engaging the secondary turbo.

Also, I agree that letting it idle about 30 seconds is good. Any longer than that and the car will just start heating up, as Adam C pointed out.

 

I can drive without boosting my car in the slightest. no problems what so ever. In a rare case if I may boost to .3 or so, but I can usually control it. Just watch the boost gauge while you hit the gas, dont let it go past 0.

off topic (BTW...Dude, I put my MP back on and OMG. Highflow cats suck the big sweaty one, trust me.)

 

You can't drive without boosting rynberg, don't listen to these guys. Even with your foot all the way off the pedal those turbos are spinning away nicely. Of course they aren't spinning at 90,000 RPM like they could be, hehe.

What they mean to say is, ummm, well, I'm not sure.

Hmmm, reading the rest of your post... Well, lets just say, it is possible for you to drive without letting the turbos create any extra pressure (in stock form anyway).

 

you can drive around without the boost gauge hitting positive boost. Are the turbos spinning? I dunno, probably. But your not boosting.

 

NEW QUESTION!

lets say i am passing by my house to pick something up. but i am parking it on the street and dont wanna risk it and leave the car idling there.

is it safe to turn off the car right after parking, getting something in the house really fast, comming out, and starting the car again, and driving off?

consider that i was boosting and i wasnt boosting. your comments would be great

 

I think everyone is paranoid about this car.

 

that was a little paranoid...

ANSWER THOUGH!

=)

 

It's fine. Zerobanger is right, everyone is too damn paranoid about this car...

 

Rynberg, I know your car is pretty heavily modded, but I have no trouble driving without boosting, meaning boost gauge stays in vac or at 0 the whole time. I live about 15 minutes from work, and I usually don't touch the boost on the way to work. (given, last time I drove the car there was snow on the ground) Your turbos probably spool up a bit faster than mine (i assum HF cat by what ZeroBanger said) but you still should be able to drive without any positive pressure.

The turbos do still spin though, so to anwer the original question, I be nice to it for the last couple minutes (this is when using boost before, mind you) and then let it idle for 30 seconds.

 

i try and stay out of boost when im daily driving to save alot on the gas. i think what everyone is saying is stay out of boost (dont go past 0psi). when your moving the air goes thru the oil cooler and radiator to cool down the turbos but when you are stop it starts to heat up again unless you have fans. i usaly drive my car out of boost the last mile or 2 before i get to my house and **** it off.

 

Nope, my car is actually not very modded, at least I don't think so. (mods in sig).

Maybe my car is different than everyone else's but once I'm in 3rd gear, I shoot up to 2-4 psi just breathing on the throttle. After the initial spike I can come close to keeping it in vacuum but it's difficult. In 4th or 5th gear, forget it. Even under light acceleration, I'm hitting 2-3 psi or more.

I think you guys relying on the PFC for a boost gauge (David.. ) are not seeing the initial boost spike on throttle tip-in.

 

Oh, you're definately boosting. If the engine was doing all of the work you would see more and more vacuum when you push down the accelerator, but you see a lessening of vacuum, or an increase of pressure (ie boosting) even if the guage never goes past the 0 PSI mark.

I'm amazed you can hit boost so easily. :shrug:

 

Do it when you have been boosting and you lessen the lifespan of the turbos and the engine somewhat (although probably not tons unless you do it a lot). If you haven't been pushing the turbos feel free to turn it off. The car is not made out of paper mache (sp).

 

thanks for all the info guys, i wasnt sure about a few things. as for the boosting, when i say driving with out boosting, i was talking about not going over 0psi on my boost gauge. It figures that you guys not suggest buying a turbo timer, when mine is on the way. i wish i would have posted this a week ago.

 

Tyler, I have my boost gauge installed, with a home made DIN panel. So im looking at the gauge. I guess IM gonna need to give you a ride in my car with the new engine (its tuned and broken in!) and show you, he he.

 

Zerobanger,

You already have a new engine AND it's broken in??? It seems like it is was just yesterday when you were at BRG(dyno day). I still have to get mine installed. BTW, tgriesel invited me to join you two at Sears point for the Wednesday night drag races. Are you dragging???

John

 

Hey John. I'm sorry I did not get to meet you at BRG. I'm more sorry I blew my engine though

yes I have 1150 miles on the new engine. It took rick under 2 weeks to do the engine. It just got tuned on Saturday (11:5 A/F) and I got rid of the dyno juice.

Im down for Wed June 25, we will all touch base on Monday of next week. Have you ever been to sears point? I never missed a Wed night last year. Even when I broke my Diff I showed up the next week (but much more poor, hehe).

David

 

You must live where there are no hills. In 3rd or higher, you can't accelerate, or even hold your speed up any moderate hill without boosting.

 

yea the bay area is pretty damn flat.

 

So how do drive up a hill in 3rd or 4th without boosting past "0"......Zero???

 

You'r talking about SF type hills? You can't if that is the case. On smaller hills try switching to a lower gear.
