i heard this from someone
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. |

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 Dave |
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 dogging it out. Use wisdom, or common sense and I think you'll be fine.

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 :D

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

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. |
