Is Hitting The Rev Limitter Bad

[r33madd]

every now and then when iv been going for a bit of a thrash i have accerdently reved right out so that it hits the factory rev limiter.

is this doing me damage and what does it do

[ebola]

just don't make a habit of it.

R32 is fuel cut (I guess R33 would be the same).

so it gets nice and lean... and nice and hot.

its better than revving the engine to 14k, though.

redline = overworking

doesn't take much to figure out that doing this alot will do damage.

*waits for the tech heads to tell why*

[Kaido_RR]

no its fine!

the rev limiter is there to stop you over-reving

[mad082]

the rev limiter to stop you reving to a point where it is no longer safe. if nissan didn't want you to rev to 7000rpm the rev limiter would be lower.

it is ok to hit it now and then, just don't sit on it.

while the fuel is cut to limit the revs, it cuts it completely so there isn't really much heat. it is just sparking into air, not into a really lean mixture, or if there was and fuel vapour it would be creating less heat than what a full amount of fuel would.

It's there to be bounced off

[Kinks]

I've seen an engine (redtop RB20) do a big end after being bounced off the limiter for a couple of seconds. It's not kind to the engine, so don't make a habit of it. Having it cut briefly on you because you didn't grab the next gear soon enough is OK.

That said, my charade used to rev its tits off.. I had mates who wouldn't get out of the car until I'd hit fuel cut at least once

[dead32]

rev limitor sounds so good though, however its not advised unless you have spare cash for a rebuild..

[GTRsean]

Bad for r32 RB26DETT's, crack ur oil pump it will.

[Roy]

Soft cut rev limits like those available on Motec/Autronic etc are kinder to the engines...but its best to avoid it if possible.

Then again, whilst its not great for the motor, if your not fussed then its hardly the end of the world...lol raise the limiter to 8,400rpm on a stf motor and go play

The harder you work the engine the faster it wears out... it's pretty basic really. As the guys said, don't make a habit of it, RB's are tough but like all engines they'll break eventually and constant high revving will only accelerate that process. Remember that engines are always in a constant state of degradation - it's only a matter of time before something needs replacing. So rev as hard as your wallet will allow

I hit the limiter a few times in my last car (Series II 33) and it still had almost identical compression when I sold it (had it for 14mths and always did the servicing with good parts).

If you're going to go hitting the limiter often, at least record it and show us so we can get our kicks without doing it ourselves

Thats quite true, although if your car was completely standard i suppose it would be ok. Nissan engineered it to be at 7000rpm from factory, not 7000rpm with mods and standard internals.... If your motor is designed to sit at a rev limiter like for drift n shit then you can sit there and drop the clutch from 7k lol but fuel cut rev limiter sounds a bit dangerous with mods i think...

get a bee*R rev limiter that will only cut ignition and not fuel.. much more safer and you get nice flames

[Butler]

the rev limiter is there in a safe place to stop you making melted steel out of ur motor. i have seen/driven many a car bouncing continuously off the rev limiter. Look at a typical drift meeting at barbs. For a good 150m we are smashing limiter up the hill in 3rd and yet to break anything. stop being so weak, get out there smash some limiter and scare some old people

not safer if you run the stock turbo.

[No Crust Racing]

Was just thinking how much a stock ceramic turbo would love the flames

[shnaped_second]

I had a cefiro with over 100k's on it and i would atleast hit limiter once a day for the 8 months i had it, its still going strong! but ive fitted a bee r to my 34 to be a bit safer

[mad082]

since the ceramic turbo loves heat so much, flames should do it the world of good.

[mad082]

my mate has a natro rb30 that revs to 9000rpm. it will sit there all day.... well not quite. but it does have a rb26 oil pump and the centre of the crank shaft has been bored out to allow more oil through to cool the bearings.
