hi ! is there any chance to raise rpm limit on n55 using public xdf file ? thanks

out of curiosity, why do you want to?

I think this is one of those threads that is worthy of this meme.

replaced turbocharger. and want to have 200-500 rpm additional.

That looks impressive...and very different than the OEM setup.

Impressive indeed. I would dyno the setup is see if you are still making power at redline.

I personally wouldn't want to raise the redline on any of my build except if you built your internals accordingly.

Wow that looks like a nice manifold set up. That should yield good power, who makes that manifold? Assuming custom, also what turbo specs

what did you change engine wise?

really no one knows/can help ?

If you didn't modify the internals of the engine, chances are you have absolutely zero to gain by raising the redline RPM. You would only need to do this if you changed camshafts. Since there are no aftermarket N55 cams, I'm going to say that you do not need to raise the redline RPM. Also, stock internals might not be able to spin that fast without failing.

yeah but you haven't said what you did motor wise to support an rpm increase. the stock motor can't do more rpm without failing

[Pussiwillow]

Ya can we know more about the build? What was done? I wouldn't touch anything with the rev limit with that set up. I doubt you're gonna struggle making power, 500 rpm isn't gonna net you a whole lot of anything but more reliability issues.

Maybe you just want to do it no matter what.
The concensus is that you shouldn't except if you built the internal to support the extra RPM.

I never increased RPM even on my race built engines, an extra 500RPM isn't going to change much but will stress the engine and reduce reliability. Reving a 7,000RPM is stressing the engine enough.

A dyno pull will tell you if your engine is still making power at a redline or not to warrant thinking about raising the RPM limit.

Or maybe you just want to do it an not hear about any warning.

yes you are right.

haha, then do it

[pacific_tune]

mate i am asking "HOW" and i cant beleive no one knows.

[Pussiwillow]

You're best to reach out to someone who actually tunes these cars, I don't think anyone here has ever had the urge to raise the rev limit, most are on stock turbo around here, you're not gonna get much info here, especially when you don't answer anyone elses questions, sorry mate

who says I don't know?

but figured since.youre obviously running a bukt and balanced race motor with a cam upgrade that you'd be able to figure it out... cause that's the only way you'll make power with a higher Rev limit and not blow it up.

How about just answering the guys questions instead of making decisions for him? Way too much of this BS in this forum

how about letting me make.my own decisions instead of making them for me

[Pussiwillow]

The guy comes in asking, we wanna know more about a build that looks wild, he wants help, posts a pic of his set up to ego flex for attention, and still ask for help like he's in disbelief we wont answer him but wont answer anything himself.
Nobody is gonna benefit from an rpm lift of 200-500
On stock cams non built engine etc etc. it's not common, whether anyone knows, don't carry an attitude of disbelief when you don't get an answer to something literally so so uncommon. His tuner could point in the right direction. I doubt the build is even his based on that alone.

Sorry mate we asked polite questions.

[pacific_tune]

motor you see is stock. but it does not matters because its a test motor. and i am pretty sure that stock can rev 200-500 rpm more without any problems. maybe without any profit but ..) please what questions more i need to answer before i get help ?
