wierd, putting my induction kit on increased turbo whistle no end. move it closer to the turbo, my turbo whistle now is really loud. obviously turning boost up helps also. stock turbo is good for 2 bar. head gasket will go b4 then.

So why are the turbos so quiet as standard?

I tried putting a pipercross filter on but it just made a huge induction roar,didnt make the turbo whistle any louder. Whats the score?

If i fit a bleed valve in line will that make any difference to the loudness of the turbo? I want as much whistle as possible :cool:

Or,is the stock turbo a piece of garbage that just doesnt make much noise no matter what?

yes, my bros standard one is quiet, and its slow as fuck.

Im still not happy with the turbo whistle on mine.You can hardly hear the damn thing spool up.You can feel the power but theres not much whistle.Are they all so quiet?

can u tune a 1.4 8 valve up as much as u can a 1.5 turbo?

in europe they did an intercooled 1.5 td in the mk2 astra that pushed out 75 bhp (8bhp up on standard) so working on it being the same intercooler as the 1.7 one then that should be the same increase if u use a 1.7 intercooler which i have, although this will also allow you too run higher boost pressures, reason im not going above 1 bar is becasue the safety cut off valve is at 1.1 bar, perfectly safe to run upto 1.3 bar with an intercooler, hmm 110-115 bhp :)

How much Bhp are all you TD owners getting?

move the filter to the other side kris, a lot more air and space there

moved my filter and it has a lovely whistle now :D

1. yes it acts as a resonater, once i moved the filter to the other side there is a lot more induction noise and whistle. turning the boost up also increases the turbo whistle, had mine running 1bar for 18 months and not had a single problem with the engine. changing the filter makes more whistle than upping the boost though.

Sorry to bring this topic back to the top but i have a question.

Does the big stupid inlet manifold play any part in silencing the turbo whistle? On my TD you can hardly hear the turbo spooling up,its very quiet.Has anyone upped the boost? I reckon that might give a louder whistle.

1. no, cos the top of the inlet pipe is empty anyway, you can look straight through it, im gonna take the top bit off mine anyway, its a waste of time leaving it there.

2. powersteering resovoir is in the way, my bro has pas on his td and i measured up my cone to the gap and there isnt a hope in hell it will fit in. hes just stuck to my old drilled airbox now.

Hello again, seen the pic of the white corsa engine with the dirty big cone
on the turbo pipe........ One question, now that u have no filter or pipe
going to the intake manifold, are u not worried that if anything goes in there when your doing like the tonn, that u might fuck up the engine!!!
Also why cant one with power-sterring not fit???:rolleyes:

oh, if u have powersteering or abs then you wont be able to do this mod as there is far too much stuff in the way.

i know, thats what im gonna do, ive got to cut the turbo hose first and didnt wanna do it until i knew what it was gonna be like.

althoguh im gonna move mine again, so there is even less piping between the filter and turbo.
