Would there be a reason why my engine revs until 8000?

Is there a way to adjust the rev-limiter?

Change gears earlier LOL, seriously its not making power up there anyway, and its not going to do teh conrods much good. Its probably got a remapped ecu, have a look at the ecu and see if its got any stickers on it.

Just checked the ECU, no stickers other than the original part. no. 23710 21U01.

I thought the stock ECU couldn't be tweaked? I gotta get a rev-limiter adjusted, don't want to f*ck me car.

use the rev limiter god gave you - your brain.. :P

funny you should say that. I have a central 20 ecu, and it has two limits set, a soft limit at 7200 rpm and a hard limit at 8500.

If i sit in neutral, and blimp the throtle, the car will rev straight up to 8500 and basically turn of anf off, not like a rpm limiter at all, but if the car is in gear, and you blimp the throtle it will only go up to 7200 and no more. strange

sorry to go a little of topic but at what revs does the power ban stop??? i normally change at 6500 and at times when i get a little to excited change it exactly on 7k.

so when one would be dragging (legally ofcoarse) whats the best rev to change gears in?

It should be 6900rpm as has been said. Much more than that... particularly on a relatively stock car... and you're going to do some damage over time.

The OP has asked a legitimate question, and you all act like you've never bounced it before... haha.

lol!

rev limit is there to be smash in an rb... no need for shiftlight when ur hear it smashing of the limiter u know its time to change gears..

8000rpm is alittle high but maybe its just ur tacho jumping around when u hit it

Actually it went past 8000 so I'm not 100% sure where its stopping. Hope I haven't damaged the engine.

actually, thats a really poorly thought out statement.

The limiter isn't there to be smashed, its there to semi protect the engine from over rev.

A lot of people don't realise that hitting the rev limiter is quite dangerous (if its a hard limiter which the stock ECU and powerfc is) - It spreads uneven power over the crank, forcing it all over the place. And in some cases, crank walk. This is very bad, I have pulled down an engine and seen what happens when you bounce it off constantly. Its not pretty.

I've been down the drag strip 20+ times and out of 20 runs x 4 gear changes each (Total of 80 high rpm gear changes), I've probably hit the limiter less times that I can count on one hand. Its not hard. Just use your common sense.

And no, its not an indication on when to shift. If you need a rev limiter to know when to change gears, then you should sell your car and by a push bike.

You'll be right, just don't rev it past 7,000rpm anymore.

lol or buy my Gizzmo interface :sick: (http://www.skylinesaustralia.com/forums/t189545.html) it will plug straight in without ANY soldering. Can be used as launch control or rev limiter. Has a shift light too ;)

never had an issue with my engine ... never said anything about drag racing... thats a difference story.

my 25 revs out to 7300rpm without a problem, no point stopping at 7000rpm when i make power all the way to 7300rpm :)

and if u miss it i was joking lol! guess u never heard the joke - limiter is the blind man's shift light? lol

lol!

    • Yeah I've spotted this one too, whenever it's lotto superdraw week and I'm browsing car sales dot com for my new ride They must be dreaming, maybe it's worth 150k for the link to Brock?
    • 100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!  
    • ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
    • Remember reading about this not too long ago. been for sale for a long time  this is like when the wife says you need to sell the car so you put it up for a ridiculous price no one will pay
    • You are perhaps suggesting that it is not a super car? Well....it's not an AU.
