Whistling Sound, Fitted New Cooler

[nsta]

Just wondering if everyone else noticed a whistling sort of sound just after fitting a fmic to their r33 gtst? i hope its not jst me, theres no leaks to be found, and the cooler runs fine on boost? Im thinking its the sound of the air going through the fins from the cooler, but amplified cause its larger than stock???

I get that too, Is it a hybrid or hybrid copy??

[danielson]

i have a big hybrid job as well, and it whistles really bad. but i have a gt30r turbo, so could be that also....

[Bunta]

I guess the hybrids didnt get the nickname "the Chineese whistler" for nothing, It is ghey and annoys me (Came with my new car) and I will be changing it to a better brand! The HKS cooler on my old car never made funy noises!

[nsta]

hahaha yip you got it genuine Hybrid gt spec....yeh not too annoying lol, no yet anyways

[danielson]

i thnk it sounds phat. ppl thnk ur running huge boost. and then u larf at em... hahaha :lol:

Gotta love induction noise?! OR is it? After fitting an aftermarket bov to my old WRX had a leaking seal... and it had a MASSIVE high pitched shreeeek to it... shit me off no end and so took it off and sealed her up... Otherwise... might just be induction noise?

Cheers

It is nothing to worry about, as long as you dont mind the soud it is fine! It is to do with the design of the core or the piping, Almost all of the older ones whistled though someone told me the newer ones didnt as much

Mine isnt induction noise mine souds like a tea kettle boiling when held at constant throttle at around 3000rpm

[nsta]

haha, yeah bunta definitely not induction noise, as im not really tapping the throttle at all when i hear the noise, usually hear it when im just cruising around.

The induction noise does sound more pronounced with a hybrid though

[paulr33]

mine too whitles, china hack up copy. does the job as far as i know

[nsta]

yeh mine does the job well indeed, love the induction, can live with the whistling, all seems fine then

[TTT]

it's the pipe kit.

a lot of nissan silvia guys were getting this too.

one guy on there has a workshop where he does pipe work (exhaust, intake, intercooler etc) and none of the cars he's done with hybrid or hybrid copy cores, using his pipes have the wistle sound, but a lot of (not all) the hybrid type coolers that come as kits with piping, make the stupid whistle sound.

[33SOM]

Ive got a proper hybrid cooler and it doesnt make any noises. So id say it must be the piping as mine custom.

[daler32]

last 2 times we had whistling noises in our cars ones an r 32 gtst and the othe a s13 sr20det turned out to be exhaust probs. the rb20 was broken exhaust manifold studs. then sr20 was an buggered exhaust gasket between the turbo and the manifold. the studs cost us bout 900 bucks and the exhaust gasket shoulda cost me bout 500 but yeah both pricey exercises.

Some ChinaCopy Cooler have Whistls...

[MYS013]

I had the whistle, It was due to slight leak. Just needed to nip the clamp up and it was fine.

I have a hybrid copy and it does not whistle now.

holly shitballs batman..

you got ripped off baaaaaaaaaad.

turbo -> exhaust gaskets cost about $27 from GCG.

manifold bolts.. if they were snapped, you could have had them drilled out for next to nothing, then new stainless bolts for under $50 for sure.

[nsta]

mm now this has got me thinking its a leak.......but everyone seems to think the whistles normal for hybrids so im gnna assume so, ive checked all my clamps and they seem tight, no leaks i can see anyways.

Yeah sorry I 2nd that - I had a new turbo/exhaust gasket done for my Stagea, added with a custom recut/weld on the dump pipe.

All up for the shops hassle was around $120 by memory(?)... plus the $1500 for the rest of the stuff I had done, like SITC install, SAFC retune etc!!

Btw - my Apex'i "Hybrid" 2ndhand fmic has a slight whistle, nothing much really, probably my dodgey-brothers home installation and ebay cut-up pipe kit (although I used 4ply hose throughout).
