What if you forget you were parked butt in first? ;)

By the way, I crank mine up, start driving about a minute after, but I don't boost till operating temps are at norm.

about 5-7 min

I warm mine up to 25C on my commander before I leave my driveway. Then I dont boost until 83C. But after that all bets are off. :)

IM COMPULSIVE SO I LET MINE WARM UP
FOR 10 MINUTES {EVEN THO IT HAS 115,000 MILES

I start driving it asap, cus its gonna be running anyways, and its bad for it to run when cold, so very light driving can't be any worse. It revs at like 2500 anyways, so why not drive it an just keep it below 2500 rpms and in vacuum?

I don't boost til I see 80C on the Commander, which usually sucks cus I always see a vette when my car is cold and I can't hand it to him.

Hi,

I used to read in a book somewhere that rotary engine has diffirent internal stuff....something like the seal or something else that are not Metal. According to the author, it's not wise to put too much load, which is driving or reving the rotor, on the engine if it's not in its operating temp. It's believed that the wear would be a lot greater than doing that to pistons engine.

So, I warm it up until the rev sattles....maybe around 75 c. and drive it nicely till the engine is fully in operating temp...82 -84 c before I put all the boost.

BTW. I'm not really familiar with internal stuff of our engines, so if you know better, please discuss for others to know better.

I use a 5-minute warm up to "pre-flight" the aircraft. Give it the once-around, checking tread/tire pressure, pad wear, any scratches, odd noises, check shock rebound dampening, sometimes light and signal operation, etc.

Warming up, depends how far I am going. If it's a quick run to the store I'll let it warm up and inhale those beautiful fumes in the garage, heating my legs by the cat-back tip before heading off. Makes a heckuva garage heater, even with no pre-cat. :D

Anyone else get the 3-5 rev idle fluctuation as the AWS kicks off?

ZeroBanger 12-19-03 01:38 PM

I warm up until the temp reaches between 100 and 115 F. At that point, its down hill for quite a while, so I just coast it, lol.

I dont hit more than 2 or 3 PSI until its at 175 F or more. I go into WOT until I've been driving for 6-7 minutes or so (Usually 185 or higher temps).

Sorry I am kind of a newb but what does the term "in vacuum" mean?

fastcarfreak 12-20-03 12:01 AM

i wait till its about 70 degrees C on the power fc. then keep out of boost till it hits mid 80s. Normal operating temps for my car is about 86-87 C.

He just means he keeps his boost gauge out of boost, i.e. the engine is not at positive pressure.

cloud9 12-20-03 02:38 AM

oh ok thanks

RE13REW 12-20-03 03:33 AM

10 - 12 mins usually.... it is really depend.... take a little more in winter

skunks 12-20-03 04:37 AM

just drive it but keep it under 3krpm and outof boost till you hit at least 180degrees

BLKTOPTRVL 12-27-03 06:03 PM

Moving as soon as the idle steadies, then easy rolling until warm.

odditysmurf 12-27-03 06:18 PM

85-90 deg. C. about 10 to 15 min of warm up time.

RonKMiller 12-27-03 06:25 PM

I like to let mine rev freely to 3500 rpm without kicking it down for 5 minutes. I run straight 50W oil during cold weather 'cause it sticks like snot to the rotor housings and gives me an extra measure of protection on start up.

I then drive at full boost to the 7-11 one half mile away and pick up some brewskis, then back home.

Before shutting her down I like to rev it a few more times to about 7 or 8K, just to see if the rev limiter really works, and to hear the sound of my extra loud N1 duals and midpipe reverberate off my neighbor's houses.

This way I never have to worry about any overheating issues.

jspecracer7 12-27-03 08:38 PM

I normally just start the car and drive. Keep out of boost and keep it below 3.5k rpms until the water temps hit 70 C...then redline:D

clayne 12-27-03 10:36 PM

In all seriousness, there was a period of time where I was letting it get to 60C and then leaving. The issue was that if i I drove it and came to a stop (let off throttle) the revs would drop to around 200 and the car would die. Once it was above 60C this never happened.

After doing some searching I found that the PFC Water Temp fuel enrichment settings needed to be adjusted so I moved them 2 notches up for each setting and the car never died again.

I still have some funkyness though. Upon startup revs are around 850 (what I set it to) due to TB coolant bypass. No problem there. However the second I hit 60C (and it did this even before I adjusted the water temp settings in the PFC) it will jump up to 1200 rpm then slowly settle back down to 800 by the time I hit full operating temp.

It has to be some other form of PFC setting.

Sorry to hijack the thread over that.
