i heard that you have to let the car, if you start it, run for at least 30 mins before shutting it off. i dont think thats true but i have read on here that you have to keep it running until it gets to full operating temp before turning it off.

are these engines particularly finacky(sp)? meaning, do i have to baby it until it warms up to avoid potential problems? of course im not going to beat on it when it cold but a lot of people are telling me that you have handle it like a newborn baby.

 

haha. 30 minutes? they are wrong. i start my car, then turn it off within seconds plenty of times.

i think IMO piston engines are way more finiky(spelling LOL) i just think because its new for a lot of people, even me, they understand more of how a piston engine works.


dont redline it until it warms up completly, i only let mine sit to warm up if it gets really really cold, but it never does lol.

but these are all just my opinions and what i have learned.

 

If you start the engine from cold and shut if off within about the first 30 seconds it can sometimes but not always cause the engine to flood. I've never had a problem with shutting down any time after that first short period.

You don't need to treat it any different. Just like any engine you should keep the load and revs down until it's warmed up.

 

im not sure about 30 min but yeah you should let the engine warm up first before shutting it off, or so im told, id let it idle for a min or 2 if its a cold start before turning it off

 

you were told LIE, the on-off-on-f of any motor in a really short time span will flood it, piston or rotary.

 

+1 to what people said. That and did you actually think 30 minutes was "correct" in any way? It takes about 5 minutes (driving) to warm up my engine to where it stays at...

 

no hell no, 30 mins is an exhorbidant amount of time. i just know very little about these cars and wanted to make sure that my assumptions were correct, and they are. lol i was like dude why would they make an engine and market it if it 1)couldnt be redlined at all(he said u may be able to get away with it once or twice but beyond that youre 100% screwed) and 2)you have to run it for that long everytime.

im thinking whoever told my buddy all this misinformation was maybe talking about carbed rxes

 

no he was talking about something he knows nothing about...

I normally wait till it completly warms up before I redline but I have many time just started it moved it and shut it down...

I only had it flood out once on me and that was after a 20 minute drive I shut it off went in for an hour and while cranking it fired and died and was flooded..

got that fixed in abotu 20 minutes and away I went

it is a general rule of thumb to let any motor run for a few minutes before going any where simply to allow the oil to be distributed. I think that is the only reason you would have any time constraints, But it takes probably a few seconds if that. Then of course you want it to be at its optimal temp before ******* it out. Use wisdom, or common sense and I think you'll be fine.

 

+1 my old saab floods nearly every time it stalls (ironically the stalling is usually due to fuel starvation) my rex has only flooded once

 

The carbed rex tends to flood if it sits for a while. At leased the holly 465cfm does. It usually floods after a highway drive and then shutting it off. But other than that never had a problem with starting and stopping really fast. More of when its hot and not cold.

 

I have an 88 GXL that floods every time if I don't let it warm up. It only take about 5 minutes though and it's most likely due to poor compression and leaky injectors. One day it will die... then it's rebuild and street port time

 

true but not 30 minutes! thats insane more like about 4-5 mins

 

Funny how a lot of us are waiting for the motor to die before doing anything big.

My 7 has flooded on me only once. It was mostly due to old spark plugs. As for the rotary, when I first started learning about them, I was hesitant to buy an rx7. Once I got the hang of the engine, it was just like any other engine (except for the fact that it is a rotary). I don't exactly baby it as much as I've heard you have to. I just take care of it the same way I'd take care of any of my belongings, and it has been pretty good to me.
