Limiter

[loymclure]

Well i have a rather strange question i heard that stagea's and skylines are limited to 180KM/H, if this is so am i sposed to feel some sort of lagg out or just a suddern drop in revs or what? The reason i ask is if i took my car up to 180 (could have been on a track could have been on a dyno or any thing) the speedo reads 180 but the car still feels like its accelerating and the needle bounces violently, is this normal ? Any one els had this same sporta thing?

in the pic you can see it is just above 180 and caught in the middle of its jumping.

never tried in the volvo but my gtst had the limiter at 192km/h according to the gps (on 265/35/18s), it never hit hard though maybe you have some extra herbs - more like a very gentle back off.

anyway at that speed the speedo is pretty inaccurate, assume it is 10% high, so 175 indicated = 160 real.

yeah i know my speedo is out about 200m's to the 5klm's according to the speedo checks on the hi-way might have something to do with the 19' wheels. but i sware it was heaps more then 160-180 and still pulling, still had alot more in it only reason i slowed was because of the wheels they felt like they were tram tracking.

I'm in the same boat as duncan, never got the stagea up to that speed, but my old R33 definately stopped around 190 (on a private road). it's not a sudden jump though, just a gentle reduction in speed, then it speeds up again.

my r33 keeps on going roung... last time i tried i had hicas light on and the needle went past there before i backed it off... could have kept pushing...

you can get a cut out for it, or an aftermarket ECU like i have (microtech LT-8), will cutout any motor restrictions anyway. cheers

hi

does anyone know if the ecu cuts fuel or ignition or both???

very strange there must be something wrong with my limiter because it went past 180 on the speedo and just kept bouncing back down to below 180 but there was no change in motion or pull at all ...... haha wont see me complaining.

[4drftn]

so your saying it keeps climbing but your needle on the cluster just goes spastic??? if it doesnt cut out or jerk there is no major problem... i dunno if its because its auto or not , mine being a manual (and r33) it doesnt do anything but keep going round (but also because i have aftermarket ECU) might see if i can get back round to 0km/h how fast would that be???

[loymclure]

add +- 80 ?lol

Sounds like your speed cut is working properly. As stated before, the speedo is highly inaccurate at that speed, so once the car is actually at 180km/h, the cut is activated and keeps the speed between 170-180. I can't imagine it to be violent as you are driving at a great speed. The car would still feel strong and feel like it will go faster, because basically it will, if the speed cut was disabled.

Everyone, please be very aware of what you post on these pages in regards to the speeds you claim to drive - I don't want to be handing out warnings or waving the ban stick around, and by the same token I don't want any of you to suffer any repercussions of anyone in the police or motoring authorities hitting you guys/girls up with fines and licence/rego cancellations.

If need be, change your posts where appropriate, as we DO NOT condone inappropriate (and excessive) speeds on the streets.

I agree wiyh Nick T.

The only way to get actual speed without SatNav etc, Is to measure the diameter of your tyres, get your diff and gearbox

ratios and calculate hom many ks you are doing per 1000 engine revs.

I am running 17s and this relates to approx 40kph per 1000 engine revs. If the torque converter is locked up at 4500 you wii be doing a very illegal 180.

I tend to drive more on the tacho than the speedo.

[loymclure]

fair call GODZILLA, Apologies.

[loymclure]

Hugh,

i think my next track run will be under closer monitoring. Might have to invest in a sat nav

hey I had the stagea on wakefield today...but I didn't get close enough to 180

to get rid of the fuel cut you could buy a little magic box called a PIVOT SPEEDMETER to suit an r33 gtr and this does a few things.

1) it gets rid of the 180klm cutout.

2)it will give you a more accurate readout in a digital display.

3) it will record highest speed reached and hold it until the ignition is switched off.

4)it will record 100metre 200metre 300metre and 400 metre times

5) it will record the average speed of the trip.

and i think it does a bit of other stuff too and they are around $100 aussie dollars delivered, link below.

i have one and it works a treat
