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!

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
