ive seen this happen. time for a tune up. your engine is not handling the thrashing well. could be a range of different things. depending on how exactly stalled. ie. as soon as rpm drop back down to idle state. or did it idle for abit then stall. EAch of these things signify different reasons and different things to check. speak to a tuner.

hey all

i hope someone ca help me solve this mystery.

the other night i decided to see how my car would go at really high speeds (now im talkin i got up to 170k) the car did well, held it togther nicely, but............i threw it into neutral to put less strain on the engine as i slowed down.........then she stalled. f*** knows why!??

Im thinking maybe it was cause she was at such high rpm????????? please help! this is so weird! cause the the highest i can go is 180 km so i dont understand why!!!!

170k,not cool would you like to see the result of 30k's over an comin un stuck

you's all act like you havnt done it before, which if you say it, i call BS

everyone does it atleast once, if there was no one aound her, no one in the car, she only put herself at risk which is just like if she where on the track

not that im saying i condone it

but just a note, you should have let the engine brake, i wouldnt clutch in/put it in neutral and then coast at those speeds, you want the engine to help you slow down.

NEVER EVER DO THAT AGAIN.....

This is what may have happened:

I don't know about R34's but in my R33, someone TOLD me that it has soemthing to do with my ecu not being able to correct the AFR with the blocking of the recirculation valve, or the unlikely event that too much air would be entering the engine, causing a stall, not sure how accurate that is.

I agree with what Eug said. Its probably something to do with such a drastic change in load.

Are you stupid? Why would you do that? What was wrong with leaving the car in gear?

Have you heard of engine braking?

Sorry its just thats a really stupid thing you did. No offence. How can you be in control of your car if it isn't running?

the ecu made the car stall because it was reading too much air for idle than normal, thus f**kin up the AFR mixture and making the car stall, my guess. ie, the ecu couldnt correct it in time.

lol eh?

... are u from ns.com. go back there if you are.

I'll explain what I meant to say when I come to grips with what I wrote.

This is in a N/A section why are people talking about turbo's in the first page, is it a turbo converted NA?

The revs and the air flow into the motor drop far to fast for the ECU to keep up and causes it to stall, I'm guessing you probably have a vent to atmosphere BOV which doesn't help the situation either. Best idea just put it in fifth gear and brake.

My mistake, I got the wrong Idea from this...

CArs that do that. tend to be out of shape. Ie. need tune. clogged air filter. thrashed engine. dirty idle control circuits etc. the car should come back to idle fine. Not a big drama. but thats hwy i said 'Time for a tuneup"

but she had been tuned up only a week and a half b4 it happened. air filter was changed (pod filter), fuel injectores have been cleaned out. and a service ws done about a month ago (not even!)

anyway thanks everyone! its not something im gonna do again. its just not worth it.

you know full well that i'm not out on a personal vendetta or anything.

but i'm sorry to say no that you do not have full control of the car.

with the car stalled you have no power steering, and braking is very limited.

that aside, being in full control of the car still doesn't justify it.

i'm thinking oil pressure could be your problem? not sure, i don't know anyone else who would try/think to do something like that.

what the hell? power steering is done electronically...

turn your car power on without turning over the eninge and turn the wheel...

other then that, dont speed...

wtf ?

Anyways, My magna kind of does this. If i boot it and then throw the clutch in, the revs drop to like 200 rpm then bounce back up tp normal idle

hi ur car looks good but im so confused why would u put ur car in neutral doing 170 this is beyond me someone explain. anyway i would say that because u have put it in to neutral ur ecu is gone wtf and stalled and gotten confused and stalled. i say keep the 170 180 for the drag strip and please dont do that to ur poor car :D

but im not here to bag u out no offence intented

i had this problem while i was running a pod (only at high speeds is it a problem 80+)

i figured the AFM couldn't keep up with the rapid change in air pressure and it stalls because of that. no probs since i changed back to standard airbox

yeah i think its something to do with the massively high load on the engine, with it sucking heaps of air, then with no backpressure in the intake due to the poddy, the airflow has just stopped, or created some sort of random turbulence giving the afm an incorrect reading, causing it to over fuel/under fuel, or starve it of air.

anyway moral of story, leave car in gear :)

its all well and good people saying dont do 170 etc, but if she's in the situation where she needs to /can i.e. the track, it would be equally dangerous for the engine to just stall

      Is there a good place to learn how an engine works online?

      Oh ok that makes so much sense. Thanks for clearing it up!

      And these modern "environmentally friendly" EV vehicles also run on the same smoke! When the engine, wiring, or batteries let it escape it also stops running!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Yeah - I found the same information too.. 30% open is like 85% of flow etc. So it's probably going to be minor if not completely imperceptible. I also have a larger pod filter here, will swap that on and see if there's any difference. The hardest part is finding a place to uh, test this. It's quite noticable just how much having ducting to the otherwise completely open pod cools the intake temps down. It's better boxed, or shielded but driving for 30 seconds really makes it plummet to near ambient temperatures. I recall in the past when I was a RB land and had a nice flowing airbox -  - Then I took the lid off and put a pod there, and gained 9 psi of boost and about 60kw from the restriction I didn't know I had - with the controller at same duty cycle. However finding people using over the radiator intakes having similar KPA drops at WOT on built setups makes me think there restriction could be the exhaust or potentially the headers. Either way though, there's no real estate to play with and nothing that can realistically be done about it. The original dyno plot without the airbox, and the larger pod had a better curve. It was later I added the ducting and airbox, and a smaller pod to make it fit in there...

      That's not completely truthful now is it? Any flex fuelled factory cars also had the option to run on steam.

      R33 general questions

      By Duncan · Posted

      Yeah so I guess your mechanic would know turnaround better than me....but I would have thought you had access to same day or overnight rack rebuilds there....any big city here in Australia has that service.   There are a couple of o-rings and seals involved, I guess the risk is the part is specific not general. Other option is if you can have it on stands in your garage for a while, steering rack removal is pretty simple (2 mounting brackets, 2 ball joints (separate by undoing the nut to the top of the threads, put a pry bar between the steering arm and control arm to put pressure on it then medium force on the side of the ball joint or top of the nut with a hammer to break it free) and then the trickiest bit is the splines to the steering rack (not too bad to undo, one nut then it slides out, but mark it first so you can reassemble it straight)
