My R33 has a cold ?

[ASYLUM]

ok may be a dumb n00b query but here goes...

when i take my car (95 NA R33) to the redline in 1st gear it starts 'coughing' until i change into 2nd and then at the redline in 2nd till i hit 3rd..

its sort of like a misfire but without the sudden lurching juddering loss of power.

would there be a limiter on the car? or could it be a fuel issue? or could i just be a really crap driver

the car is standard apart from an aftermarket exhaust.

its a rev limiter im guessing

[ASYLUM]

any way of finding it? removing/unplugging it? do all import skylines come over with them?

[Jimbo2000]

its the limiter,

why would you want to remove it?, its telling you "uhh dude time to change me"

[ASYLUM]

lol no i thought speed limiter as in the ones that restrict you to a certain speed...

cheers anyhoo

speed limiter is at 180km/hr

rev limiter is at like 7250 or somethin (havent driven my car in 6 months - doh!)

when i hit full revs in my car it doesnt seem to limit it like that, it kinda kills the speed.

like i will run full revs in 2nd and then my car will die kind off and slow me down it weird i dun like it.

well mine can't have one then as i have been over 180 (off the speedo) in my car a few times through Graham Farmer and near Rockingham etc

Yeah it'll be the rpm limiter but mine has stock ecu and I have had it 2cm past 180, on a private road of course

your speedo is getting less accurate as you go faster. Considering 10% accuracy allowance as per ADR rule, a ground speed of 180km/h where your speed limiter kicks in may be shown as 180km/h plus or minus 18km/h... so can be somewhere from 162km/h to 198km/h on your speedo (+/-2cm past ur 180 mark). Speedo also get less accurate as car is older, sometimes by as much as 10k at only 60km/h!

ask a copper to double check your ground speed with his radar, then you'll probably find out for sure

not all speed limiters limit you to 180klms, in a WRX it's 205 for an auto 210klms for a manual.

So it wouldn't suprise me if you could get up to 220-230klms before it limits the speed, you'll crap your self when it happens the first time.

As it feels like your've just totally f**ked your engine, real bad.

That's also saying you still have the speed limiter or it's turned on.

Also it could be just the engine's sound of requiring a change before it blows up...

Are you running stock boost?

Hey asylum,

It does sound like the rev limiter, mine makes the cold sounding noise (even tho my friend thinks its a sweet noise) when it hits redline.

But if you are not sure.. take it to your mechanic and ask him.. I'm sure if he is a good/nice mechanic he wont charge you for this. Or alternatively try to drag a car knowledgable friend next time and ask him when it happens again.
