Can't Reach High Rpm

[FeZ25]

It should turn with little resistance, yeah.

I don't think that would be the problem but hey, it takes a minute to check so may as well.

[suwidji]

ok cheers, i'll check on lunch break. I haven't had any whiny noise, i think it's moreso the engine just revving really loudly at the 3-4k range.

Had a look at acceleration dash videos on youtube, and they all make it 5-7k RPM whilst on boost easy. So now i'm definately convinced something is wrong :\

weird because it always seemed normal to me, and i've been driving it around for over a year now.

[FeZ25]

I think I've got an acceleration video, I'll take a look.

My 34 hasn't had much work done to it so it's near-stock. Should resemble something close to what you should be hearing.

How does it sound when you free-rev it? Same deal?

[34GeeTeeTee]

This is a stock NEO with LOTS of bolt ons, but the engines have NO issues revving lolz (Ignore the sound as if yours sounds like this then you have issues haha)

[FeZ25]

Here's the legendary yellow turd.

Slays Mat's 34 by a mile!

I wish.

[suwidji]

yep same deal.

i never used to free-rev past 3000 RPM because the revs sounded high, but i have been recently to the 3-4k mark to test my new boost gauge and it still sounds like engine is stressing a little bit, but the BOV goes off now when free-revving to the higher range. lol

Lolz, killed me with your traction

So are you saying yours sounds normal? If so, Hooray lol

oh wow your tacho rockets up. Mine definately doesn't do that or even reach anywhere that high

I cant hear the videos because I'm at work atm.

What camera did you guys use to record? I've tried my phone (Galaxy SII) but it doesnt work too well for audio :\

[34GeeTeeTee]

Yeah mine is pretty heavily modified so ignore that part, just showing that these engines DO rev hard and are quite strong!

Mine was just a crap phone camera OFF a videa camera lol

[suwidji]

Ok i just took a drive to mount druitt westfield from work.

I'll let the video do the talking (i haven't actually HEARD the video because i was in a rush and didn't replay it with sound on my phone lol, so not sure how audio quality is for this particular one).

That being said, It was a slow climb from 3000 to 4000 RPM, and if i held it any longer, it felt and heard like the revs were getting too high :s

Correct me if i'm wrong and if this is normal lol.

[FeZ25]

That sounds pretty normal to me.

[34GeeTeeTee]

That sounds pretty normal to me.

Sounds pretty average but hard to tell, dont hear anything abnormal?

[FeZ25]

Sounds exactly the same as mine but I didn't have my tacho in view to sight it.

Once you roll the boost up a bit more the revs climb far quicker and it feels far less laboured to get into the higher revs.

How much boost are you running?

[suwidji]

Being a really-close-to-stock car (apart from MBC andexhaust), do the revs seem like they're in the correct range though? I initially posted this thread because I wasn't sure if my revs are reading low as compared to other videos I've seen of cars when boosting. Also the tacho does a slow rise up to the 4k RPM range.

I also am not 100% sure on what exhaust I have (previous owner didn't put it on and doesn't know what the owner before him put on either), but i'll save that for another day/thread, or might just take it to a shop and ask lol.

it sounds a struggle getting it higher but, which is why im a bit iffy. I'm running 9psi with my MBC.

[FeZ25]

It sounds exactly the same as what mine did when I was at that stage.

They'll go all the way to redline, Where you're shifting is where I would shift in normal day to day driving. If I'm giving it a nackering I'll take it out to 6.5k, No problems there.

I dialed a bit more boost into mine and when I'm at WOT the revs climb stupid quick (not as quick as Mat's).

[FeZ25]

I can come meet up with you at some point and you can hear my car. I'll put the boost down to 9psi and you be the judge. But it does sound pretty normal to me.

Oh ok sweet thanks for the info and the help. I know people get frustrated when i ask silly questions haha. Takes a lot of stress and worry out of my mind.

I'll try my best to make it to the newy cruise and you can show me then, because I'm leaving this crazy island for 2 weeks to get fat in murica'

[FeZ25]

Have a burger or 10 for me in the states.

Would be cool to get more of us Sydney folk up to the Newy cruises, so if you can make it as well that'd be awsome. Let me know how you go.

The cruises have been pretty successful so far, seems to be a more regular thing up here now with the guys all chipping in to organise! Its great to see you guys making the effort to come up.... As soon as i get my cooling system sorted i should be able to join a few Sydney events too!
