Rb20det Rev Limiter?

[abu]

Hey

My car is pretty stock, came from Japan about 4 weeks ago.

Only engine modifications it has is a back exhaust and pod filter.

Basically there is no rev limiter? I have rev'd it to 8,000rpm on occasions and backed off as it didn't stop at a limiter?

Red line starts at 7,500 if I am not wrong, and it should be limited at 7,800 if I am not mistaken?

I have spoken to a few other RB20 owners and they have also had the same issue. I guess the question I am asking is, did R32 RB20DET come out with a rev limiter?

I haven't checked the ECU yet, but I doubt it would have been altered as the car is very stock.. But what would I be looking for that would show the rev limiter has been removed?

Any input would be appreciated.

Thanks in advance,

Abu

my mates rb20 revs past 8000 rpm too! he is scared to over rev it! he thinks there was no limiter so 8200 sounds possible

Yeah its very weird!

I usually rev my cars hard, but I actually really like this R32 and I'm looking after it haha

I don't want to be reving it past past recommended redline!

Has anyone experienced or seen a RB20 with a rev limiter, on standard ECU?

8,200rpm is getting fairly high into the rev range!..

yep mine was 8,200 standard auto ecu

bashed it every monday night for 3 months making 230rwkw

no probs

pretty sure its still going now

It may be "apparently" higher because the spring on the tacho needle is getting a bit "soft", and letting the needle spin further than it should.

I've noticed the tacho readout on my Wolf handset is less than the tacho in the instrument cluster.

8,200 far out. I would never rev it that hard.. well..

It struggles to rev kinda past 5,500 - 6,000 rpm due to being on standard turbo, stock intcooler and only having a cat back exhaust.

Once I get the turbo back exhaust on, cooler and bigger turbo on, with the WOLF tuned then I will rev it to that

Oh thats interesting..

No idea man, wont be able to check that until I get my WOLF in and tuned I guess, or I guess until it gets onto a dyno.

I can confirm this also.

the standard tacho is inaccurate. there is indeed a 7500 rpm limit with a hard cut at 7800. the tacho is almost 10% out. so 7500 + 10% = 8250

[Oblivion]

7,800 is the factory,

mine had an auto box now a manual box, hasnt ever changed....i have it chiped and its still the same only the speed limited was put a fair bit higher.

it shouldnt have a problem reving that high even on stock turbo....just that you wont get stuff all power up there, so its kinda pointless to rev it that high. if you have an aftermarket turbo then go for it.

[murrayis]

With my standard ecu, mine hits the limite at 8300 but my RSM says 7600ish at the time dont hold it long enough to write it down

[battery]

mines at 7500.

wheres roy he know about good limiter bashings

Is that right. Whats the reason for it being out, like where they released out from factory?

I haven't managed to actually hit limiter, even in the wet when having a bit of fun, but I tend to be cautious about how high its reving.

Ohh ok thanks man.

Yeah no point reving it that hard unless you get power that high, which you wont on standard turbo. I don't tend to rev it past 6,500rpm as it is now as it beings to struggle.

But once I get it tuned with the WOLF I will get the limiter set to about 7,800 rpm.

[murrayis]

yea the stock turbo runs out just after 5500rpm there abouts

8,300 rpm damn, thats high. Weird how they are out so much hey?

LOL @ dont hold it long enough to write it down.

[abu]

mines at 7500.

Hahaha yeah I was hoping Roy would have some input, I always read about him changing his rev limiter for different events!

[abu]

Yeah takes it in the ass somewhere around there!
