you drive around under 3 k and w/out letting it build any boost

or does it still spool caking in oil??

 

well, the turbos are still spinning at under 3k, but you're not making a huge amount of heat. Being that the turbos are liquid cooled reduces the amount of time needed to cool them down as it is, so couple that with low rpm runs and you're cooling time is virtually 0. Just coast into your parking spot and let it idle while you put up the sun shade - that should be plenty.

 

dont know about u but i just let it idle for a good few minutes. it doesnt hurt. better to waste alittle gas then having oil caking on ur turbos.

 

i actually learned from seth that over idling your car causes blow-by and is one of the reasons why you get oil all up inside your intake pipes.

and as mentioned earlier, the turbos are watercooled, so there isnt much need to idle your car for a few minutes after normal driving condition.

 

I would say no. I let mine idle for a min under almost all conditions just to be safe.

 

It's called "coking", not "caking in oil".

Why do you drive under 3K? This qualifies as "lugging" the engine and is as harmful as over revving. With their absence of mass and low end torque, rotaries are designed to spin to make useable power, and you are not going to harm it by taking advantage of it's full rpm range on a daily basis.

Idling for more than a minute is really a bad idea for any engine (ESPECIALLY when it is cold), plus you are getting 0 mpg. I agree that one minute before shut down is probably a good idea, but any longer is overkill.

 

A few things that make oil/coolant hot is driving hard and sitting in traffic (not getting any flow). If you keep it at lower rpms and keep the car moving there really isn't a need to turbo time the car. However I usually turn the fans on for like the last mile home.

 

huh? you're saying not to idle your car for a minute when you first start?

more info please.

 

If I idle for more than a minute before shutdown, I'll pop the hood to ease up on heatsoak. It's a fine line between ram-air cooling(while driving) and idling. A linear water temp guage helps alot to determine the optimal shut-down point. Ain't rotaries fun?

 

Can you explain the "lugging" theory? I've never really given it much thought and just want to know your views on it.

 

I was just using that for an example

anyways, after hard/moderate drive, I usually take it easy around my neighborhood driving under 3k and not making any boost (maybe your one of those ***** that rip around residential areas ) so I don't have to sit around on my driveway for so long, plus I don't want to stink up my garage by tting in there
