Cooler Doseing

[SMB315]

how do u get the cooler sound on a R33 like a vl Turbo, does it matter on bar n plate or fin n tube, or is it to do with the turbo, any scams or ideas??????

[Steve]

easy, buy a vl turbo,

but seriously, this is the performance forum, how is having a car sound like a different car performance related?

perhaps you could get a tape recorder and record a vl, then just play it back when you feel the need.

[dstylez]

AFAIK, the vl turbo doesn't have a BOV. So the sound you might be hearing is called 'compression surge'

[sweetr33]

lol@steve. Hehehe, matey VL's dont have a BOV from factory so the sound ur probably talking about it compressor surge. If u got a stock BOV on ur R33 take the vacuum pipe off the top of it, block it off so the manifold is sucking in unmetereed atmosphere and bobs ur uncle u have a vl sound. But this means ur bov isnt working and compressor surge is occuring. Not recommended but hey if u want the noise go for it!!!1

[sweetr33]

oh u beat me too it dstylez.

[vendetta]

hey i just got my cooler fitted and ive been getting the compression surge now but i have a hks super bov (not sequential) and i still get the surge flutter..why is this??? should i change my bov?

[Steve]

have you tried adjusting the bov?

[vendetta]

can i adjust it on just a super blow off valve? well if i get my power fc tonight which i should be ill probably meet up with you steve so i can borrow your hc. then you could show where on the super bov i can adjust it

[Steve]

no probs

[KamikazeR33]

i cant believe someone would actually wanna make ur car sound like a vl turbo

ull know notice that ur driveablitly will suffer after changing gears

[SMB315]

u turn a simple question into nonsence, i mean a coller dose as in the separtion so that it isn't fast, i have blocked the factory bov completely. and by the way this forum is for anything to do with forced induction steve.

[paulr33]

yeah the sound is from the compressor surging as its gets spun back by reverse air pressure cos the stock bov is blocked. its just like putting your head behind a desk fan and talking behind it, your voice gets "chopped". this is what happens to your turbo with the bov blocked, air comes in the other way and gets chopped by the blades. its been known to damage the turbo and slow down spool up times. the vl does it as it wasn't released from the factory with a bov so the air just back spins the turbo charger every time u close the throttle

aka "its a bad noise"

it gets amplified with an intercooler as it echo's through the piping too

[paulr33]

a lot of people dont recommend blocking the factory bov. its there for a reason. numerous people have damaged their turbo's from doing this (blocking the stock bov) cos they want the crappy "vl turbo" noise.

it sounds retarded, affects spool up times and shortens the life of your turbo

hope you have some money around to rebuild the turbo if you wanna keep your stock bov blocked and have the silly noise

[vendetta]

well tell me how i get this noise when i put my bov on my r33, its on std boost as well. Even my old sil80 sr20det was std boost i had filter and bov and it still made this noise. How can it be bad when i still have my bov???

[KamikazeR33]

cos the bov isnt opening enough - just an easy adjust or buy a better bov that works

i wouldnt recommend doing this SMB315, as many a vl turbo has gone to heaven over the yrs

[Steve]

sorry SMB315, I thought forced induction performance meant forced induction performance

but rest assured - there is no way I will be replying to another of your posts.

[SMB315]

dont really care bud

[OVL-747]

hehehehe what a funny thread

not all vl turbos make this sound

anyway as described earlier , if u want flutter , ditch the bov , throw a pod filter on , and after a few months , rebuild ur turbo.

flutter sounds cool , but is also damaging to ur turbo in the long run.

[Trust33]

Drive in a higher gear than normal you will be going slower than normal not gaining speed as fast as you normally would in a lower gear keep your foot planted enough to keeep you going change gears and you will get the ''chop chop'' flutter sound.

[SMB315]

thats true, like in 4th and 5th past 100k's, i get a longer seperation, my mate just got a t3/t4 on his 33, much better chop sound and with more boost comes the higher pitch dose.
