Power Fc

[paulr33]

mythbusters ahoy!

standard powerfc

FUEL CUT on REV LIMIT (which is set via hand controller) (or datalogit) - there is no other way to adjust it

powerfc pro

SPARK CUT on REV LIMIT (which is set via hand controller) (or datalogit) - there is no other way to adjust it

+ also with launch control

Paul has dedicated his life on this matter........

just confirming that Paul is 100% correct, and there is nothing wrong with the powerfc rev limiter. Its better than any other attachment you can install.

The bang bang you get from an ignition cut system is MUCH louder!

[Adz2332]

ok well i did it, i set it to 6950 last night.

two things.

1. even tho it was set at 6950 it still spiked out to 7215rpm when i hit the rev limit hard. is that normal?

and

2. Does it hurt the engine or anything bouncing it off the limiter?

[Angus Smart]

do you have to turn car off and back on again to get the settings to stay in?

i've not fiddled with a power fc for a while

tho maybe not true, as i remember sitting at lights and adjusting the launch control (gti-r) and that changed right away. now there was a few funny looks from other motorists, Bang bang bang bang!

[Guilt-Toy]

No

Oil pump gears don't like rev limiters, esp if you like bouncing at high rpms. Like a jackhammer on the inner oil pump gear. Thats all I'll say

[R31Nismoid]

^^ agree'd.

And ye, sometimes the PFC rev limit does go 100-200rpm over when you smash it... which you shouldnt be doing

[Adz2332]

no i wont do it lol, i was just seeing if i set it properly....

wouldnt normally get any where near those rpms!

cheers tho guys!

[R31Nismoid]

why not?

7000rpm isnt a problem for a stock RB26

[Adz2332]

so your saying hitting 7000rpm on a daily basis is fine?

[TiTAN]

if the engine couldn't rev happily to 8000rpm they wouldn't have put the factory rev limiter there.

So what I said about the factory limiter being at 8000RPM is correct?

Why the hell lower it to 6950 then!!! It's CRAZY TALK!

[Adz2332]

ive been told that 8000 is way to high and should reali be kept around 7000revs... so daily i wouldnt need any more then that.

Just being safe..

On a daily car, it is fine.

On the race track, stick a bit lower down. (This is why the ex bathurst GTR ran a 7000RPM limiter on race day, but during prac/qual ran 8000RPM...)

[badgtr34]

also dude, if its your daily, how many times in a day are you going to be bouncing off you rev limiter?? im sure you will give it a squirt here and there, and if you do, having you rev limit at 7500rpm is fine, even 8000rpm! but just dont sit there and bounce, obviously then you asking for trouble. with these motors, in first and second you still pull when hitting 6500 - 7500 or so, so if your changing gears early, then you wont be inside your torque range in the next gears.. and so on...

[R31Nismoid]

so your saying hitting 7000rpm on a daily basis is fine?

Is this a trick question or a very silly one?

Not sure... so im gonna reply with one of my own

You sit on the limiter daily driving?

No.

So of course its fine for a daily driver.

Bouncing of a 7k limiter would be FAR WORSE than reving the car to 7500rpm and changing naturally.

You often come here with some misinformation, so wherever you keep getting it from, you need to stop going there or talking to that person.

7500rpm would be FINE. However, are you making power there on the stock turbos? Probably not that much so changing from 7k-7.5k would be the spot
