High Pitched Turbo Spool After Front/dump Install

[Bumblebee]

hahah, i remember u now.. ur the guy who thinks the 4wd system on a gtr has almost no losses hahaha yer good one mate

everyone here knows u dont know anything at all.. so why even bother puttin in ur say when its always bullshit anyway?

maybe u should just sit back, be a mod and just let the experts handle this department

Funny that the whole drivetrain loss has been proven with back to back results on 400awkw+

I don't think you've searched and read them yet have you?

I wouldn't call you an expert at all, far from it.

[Bumblebee]

well it hasnt been proven

its actually been proven by the guys who invented measuring units.. u know.. those guys called ENGINEERS??

and uve been proven wrong as well by many other forum users so dont bother arguing dude..

the day a drive train has minimal losses, will be the day that fuel usage drops to like 2lt/100 in a 300kw car

but as it stands by today, the loss is about 30% and i wont bother gettin into it with u, because uve already been proven

wrong by everyone else on this forum

what power does a dyno read when i you give 400rwhp car a 100 shot?

470rwhp or 500rwhp?

The exhaust gasket between the dump/turbo was reused.

Im running standard boost 10psi and always have. Just full exhaust and smic thats it.

Cheers all for the comments, ill replace both gaskets on the front/dump and see if that reduces the sound.

Thanks

after you do that please let us know whether it still makes the sound, double check it too just to make sure it's not leaking, so we know if there really was a leak or not for reference..

i guess everyone who's posted here are just trying to help out, everyone's got different thoughts from their own experience, hence different approach and different comments..

everyone should be entitled to have their own say, lets just read it carefully to make sure there's no misunderstanding, and respect it, if you do think otherwise, just say what you think but i dont think there's a need to aim your fire at anyone if their opinion's different to yours.

oh yeah i used a carbon cleaner to check to see if i had any leak. you will see the white smoke come out where ever the leak was like mine did. that or soapy water i guess.

[Equinox]

It's fine.

Yes of course you will loose low end response. You've got a much bigger surface area on your new pipe, so it will radiate heat alot quicker than the stock unit, reducing exhaust velocity and therefore torque. However as revs increase, the extra flow outweighs this, and you begin to make more torque.

The noise is probably normal. Turbos make sounds like that.

[NYTSKY]

It will be a leak of some sort.I had this exact same dump pipe on my car(this exact one in question) i had no weird noises at all.The only noise that was different was i could now hear the turbo spool through the thinner wall of the dump compared to the thicker stock one.

EDIT: Maybe this weird noise you hear is the sound of the turbo spooling??? Just louder now that you have the dump pipe in.

[The Mafia]

well, I bet its the gaskets between the turbo and manifold.

Nismoid is right, the head to manifold gasket makes a tractor sound.

The Manifold to turbo gaskets make the high pitched sound. How do I know? Because mine is doing it, my studs are stretching and I need to keep tightening them.

There is even a little brown spot where its leaking. It sounds like a kettle, or like how the redneck bushman put 2 gunm leaves together and blow through them and make that stupid sound.

Thats what happens when the gaskets are loose - they make that squeal.

I'm in the process of removing the turbo and changing mine too.

Bumblebee, you may say you have done 1000's of cars, which I doubt you've done 1000's of Turbo charged Skylines, but do you hae one that has had a turbo upgrade, makes some power, and is actually doing it all the time to know what you're talking about?

I doubt it.

[W0rp3D]

did you find out what the problem is?

[chiksluvit]

any updates?

[Rekin]

edit:

Well took my car back to the mechanic to re-check the gaskets, they checked the gaskets and said everything was fine..

I guess its normal then?

cheers

[NYTSKY]

I hope you are not mistaking this noise for the louder turbo spool noise as a result of fitting this dump pipe.

sound doesnt worry me, i was more concerned about the less response in the lower rev range, but im used to it now hehe
