Can't Reach High Rpm

[suwidji]

So i've been reading around and watched some youtube videos of people driving with their revs up as high as 7 or 8000RPM.

I don't take my car on track or anything, but when i'm boosting on the roads and i reach up to 3100 RPM(ish), it sounds like my car is going to blow or something if i don't shift. Just wondering... why? How come i can't even reach 4000RPM without sounding like something under the hood is going to pop?? lol

Or am i being a pussy and just shifting too early?

I'd recommend providing a video of this if you could...if you're CORRECT in saying that it sounds like it's revving really high, it's possible that the tacho is displaying incorrectly.

[FeZ25]

3100rpm isn't high at all.

Definately post a video, would help. Troy's probably on the money with the tacho being out.

[suwidji]

hmm ok, I'll try provide one later this arvo.

It reaches up 3k RPM pretty easy, but is slow to go any higher. It still climbs, but not very fast :\

[darksky34]

would like to add my 2c to this, I have a 99 GTT as well.

i recently was discussing this with my mate. and i was saying the EXACT same thing as you suwidji. It feels like I can only go to around 20km/h before i reach around 3k RPM and then any higher my engine will be very loud revving like a whiny bi(atch - is this normal? furthermore my second gear will only take me to about 40km/h before the revs start climbing above 3k RPM again and revving similar. and so on, until i'm in 5th gear at ~90km

yeh sounds familiar lol, normally i shift around 2.5-3000 RPM which usally looks like this:

1st: 0-20km/h

2nd: 20-40km/h

3rd: 40-60km/h

4th: 60-80km/h

5th: 80+km/h

It doesn't SCREAM at this point, like it's normal and safe (sounding), but when im boosting from 2nd, my revs don't exactly reach over 3.5-4k very easily but the revs sound high.

No its not normal and i wouldnt keep driving like that until you diagnose it properly.... The descriptions arent the best so it could be lack of spark/fuel, turbo issues or blown cooler hose or many other things... Video will help i guess!

I've been driving this way for almost a year now (in terms of shifting at around 2500-3000RPM and those speeds) and i always thought it was normal. lol but now that you say it isnt, im worried. Will definately get a video up this arvo. Not sure how the sound quality will be (i've tried recording a drive once and you cant really hear anything), but hopefully will help :\

[darksky34]

haha yes. please. video so i know if it's the same as mine. strange since i have a black GTT too

but my mate says it's just that i'm not used to the engine...

Get the video up and see how it goes.... I'd have a look but i dont think i am down that way for a while yet.... Unless you want to tag along with some Sydney boys on the 17th and come to one of our Newy cruises and we can have a look at it for ya?

[FeZ25]

I'd come take a look but I probably don't have that expertise you'd be after. Should definately drag ass up to newy on the 17th with us though.

they made black GTT's bodge! loljks, yeh im not sure, i was thinking the same thing,... i might not be used to the engine... but idk.

& yeh thanks mat and andrew. I'lm thinking of joining the cruise, but as i posted in that thread, i'm coming back from the states ON the 17th, so it depends how jetlagged i feel lol.

[FeZ25]

110% chance i'll be beerlagged on the day so you won't be the only one feeling awful.

Well if you come up there are plenty of us willing to have a look and help mate! Its what SAU is all about

Mother of God!!!

Oh and as i just said to Darksky, if its just sound then check the turbo gasket etc to make sure its not something simple

This is so obviously a seized fan clutch. Replace with a good second hand one from a wreckers.

[darksky34]

GTSBoy, any chance you can elaborate? Still learning my way around the internals

[FeZ25]

With your car off try and turn the radiator fan with your hand.

If it doesn't turn it's seized. If it turns super freely it's also broken.

I can't stress enough that I did write "WITH YOUR CAR OFF"

The clutch fan should create a loud howl noise as the fan will be locked up...... You mentioned a whiny sounds so you need to be more specific for E-diagnosis to work lol

[darksky34]

Cool thanks will try that WITH MY CAR OFF tonight maybe!

edit: no howling, just a revving noise which is high.

as a comparison, being in my friend's 33, at the same 1st gear, 2-3k RPM his engine will be much quieter without the loud revving that will be heard if i was in 1st and at say 3k RPM.

which is why I am thinking that is weird. But I will either try and get a video/sound recording. Would be over the weekend though.

awww but it would be so much more fun with it on!

But seriously, how should it be turning? Should it be turning with a little resistance?
