louder turkey.....?

[MSP#735]

is there anyway that i could maybe make my turkey louder? as of now i have a CAI, SMIC, DP (mods that alter the 'turkey') what else would i maybe do?

[Notorious]

Remove your bypass valve. The turkey is compressor surge, more wouldn't be good.

[MSP#735]

uh huh......

[orng1]

Raise the boost. More air more TURKEY!

When I recirculated my type-s BOV off the IC -> TB pipe into the Injen intake it was very loud, and occured whenever I let up on the gas. Didn't even have to be in boost. MontrealMSP has also tried this and had the same results.

but dude..... turkey sucks

[MSP#735]

damn, i love the turkey! this has been an ongoing concern by many.....

lol... i dont think it sounds bad... havent people noticed this before the left the show room...? i did on the test drive...

[peepsalot]

hardpipes maybe?

[CommieSpeed]

I like the turkey, but I am thinking about killing it soon. It does sound really cool though, and it scares the crap out of people. I thought we have established MANY TIMES that the turkey isn't the result of damaging compressor surge. More boost always seems to equal more turkey...so just increase it that way. My buddy who runs higher boost than me has hella more turkey in every gear.

[Dexter]

Would someone who KNOWS and is highly educated come and settle the turkey/compressor surge crap ONCE AND FOR ALL?

[mspdfreak]

Turkey Is Not Compressor Surge. Turkey Is Good. End Of Argument...SHUT THE FUCK UP!

[Notorious]

I'll do it right now. This is especially easy to prove for people with aftermarket BOV because they are adjustable. Here is a little test.

I'll assume you have the valve adjusted so you don't have the "turkey" and the most likely the valve will be set on the loose end of the spectrum. To get the turkey tighten the valve all the way, or go one step further and disconnect the vacuum source on the valve so it won't open at all. It'll be easy to hear the turkey.

This occurs because when the throttle body plate closes the air flow is deflected back towards the turbo and the pressure spikes inside the pipes. The "chuff chuff chuff" sound you hear is the air hitting the compressor blades. It's a common issue for turbocharged cars.

While it won't do immediate damage it is putting stress on the turbo shaft. Not to the point where you'll do immediate damage but it can definately wear a turbo faster. The compressor surge increases with more boost becuase of just that, more boost and the inability of the stock bpv to bleed off the excess pressure quick enough.

So despite that information you state, why do people still say it is not compressor surge?

[Notorious]

Thats what I want to know?

[mspdfreak]

I was just messin' around. I know it's compressor surge, but at stock boost it's nothing to worry about. Now, if you're boosting say, 10psi or more...I'd be worried about premature turbo failure.

[MSP#735]

yea well me, i am boosting 9-9.5 PSI with the stock BPV, pondering gettin a better one but wasnt exactly sure what i should do....thanks for the discussions and input!

[CasopoliS]

Yes at those levels you might like a newer valve. The Boost Sciences Reflex BPV is a nice one, so is the Forge.

[CommieSpeed]

I want a Disney BOV, that is animated, sentient, and just screams whatever it wants when I shift. Whenever I open my hood, it should talk to me and make sassy comments.
OR...OR, If I lived in prehistoric times, I would most likely use a small taradactyl or bird as a BOV. Anyway...it is possible to install a HKS SSQ without stalling, right?

[MSP#735]

umm.....ok...

[ChiMSP]

damn, i love the turkey! this has been an ongoing concern by many.....
Do you know what turkey really is? I didn't know what it was until I put hard pipes on. Turkey sounds like an actual turkey!!! Gobble gobble! How can you like that embarrasing ass sound?

[jurgs01]

How can I get more pinging guys? I just love the sound of detonation and am wondering how I can get it to be louder!(braindead (no) (jerkit) (loser) (yupnope) (chair) (hand) (bang) :rolleyes:

[MSP#735]

yea - thanks guys............

[ChiMSP]

mine was a valid question, i'm not trying to be dick.

[MSP#735]

i like it because its different, its not that same bullshit that everyother turbo chargered car has...that "swoosh" - why be like everyone else? now if its gonna completely destroy my turbo, then ill buy an aftermarket BPV but, then again who knows...

[jurgs01]

Not only does the backpressure from the closing of your TB cause wear on your turbo, but it slows the time between shifts that your turbo spools up. The cavitation of air is terrible for your turbo and spool up time. So, let's see, slow down the car and create wear and tear so I can have a cool sound. It's your car, but to me that's the dumbest thing I've ever heard.

But, if you do want a turkey, then just take off your BPV and BOV. Don't recirculate or vent! Crank the boost up to 10psi (and get hardpipes). Then you will have mad turkey dude!

[MSP #167]

but see the problem is, to fully eliminate the turkey you have to run a dual setup. It still has not been discovered how to get rid of it totally. I have a greddy type s recirculating and on fully soft setting and i still get mad turkey.

I don't have the money to get another flange welded on so that i can add a bpv.

[peepsalot]

I have absolutely no turkey and only a single BPV. The dual setup is overrated rubbish.

how do you have it set up? I have no more solutions for it.

[peepsalot]

Mitsubishi BPV, the stock one on the right in this pic. BEGI FMIC with hardpipe from Turbo to IC, the nipple is a large diameter, to match the BPV. A reducer is required to fit back into the intake nipple. Provided by Corky Bell, the name you know. :D

i want a BOV that goes "HEE-HAWWWW" like a donkey.

VROOOOOOOM HEEEE HAWWWWWWWWWWWW

What intake do you have?

Lol. Good one.

This is becoming my sig for a while. I hope you don't mind ;)

Perhaps one day car owners will enjoy customized BOV's...like polyphonic ringers :D.

maha go ahead. the turkey is nice and all, but in all seriousness, i'd rather have a longer lasting turbo then one with fucked up compressor blades.

and yes, it'd be awesome if BOVs could make custom sounds like HEE HAWW or BAWK BAWK BUHKAW like a chicken. or maybe a farting sound. VROOOM PFFOOOOOT

I have never been able to acomplish this. What is your setup? Pics? Thanks.

Did you try removing the smaller spring on the inside?

[Notorious]

Well you probably won't fuck up the compressor blades, but over the long term you will have more shaft play when compared to a turbo without compressor surge.

The turkey is NOT compressor surge on the MSP. Its due to the air recirculating back into the stock FMIC and hitting air that coming from the turbo outlet. In other cars, and with most aftermarket FMIC's the turkey is fixed by recirculating the air back into the intake side of the turbo after the MAF. This will give you a nice Whoooosh!

Now on the second setup, if you have your BPV/BOV setup too tight the boosted air comes back to the turbo and makes turbulance when it hits the turbo fins and tryes to spin them the opposite way when its pushin air. This is stressfull to the turbo and can damage it.

[Notorious]

I'm going to have to disagree here. I'm going to assume that you are talking about the stock SMIC and an aftermarket FMIC. Please correct me if I misunderstand. With the stock setup air does recirculate after the maf in the intake through the turbo for one continuous flow as it should be.

This is how it should work. TB closes, BOV opens -> Air releases from pipes through BOV to intake pipe after MAF -> flows through turbo -> back through BOV -> etc etc until the BOV closes. The turbo should always be freely spinning air with no resistance coming back through the pipes back to the turbo. It should be one continuous loop if you know what I mean.

The second paragraph you have described is most definately compressor surge, although you will usually blow apart a connector first on a pipe.

You are 100% correct on this. (except that if you are recirculating you are probably using a bpv (diverter valve), not a BOV). The turkey is cavitation in the pipes of air that has nowhere to go.

Dude i know you know what your talking about so dont get mad when i say (bowdown)

Funny how the RSX guy is tellin MSP owners what to do wtih our STOCK FMIC...

[MetalSpeed]

So what would be the best setup for the MSP with a new FMIC, Dual or single setup? just looking out because I was planning to buy a FMIC this christmas coming up.

[jurgs01]

Ghost is correct also (he is saying the same thing). It is also true that the back pressure is not compressor surge. Compressor surge is something completely different that happens when the fins are not getting the correct pressure from the air (like when a jet stops and the wings have no lift).

or maybe cuz his wife has an msp and they work on it together...

man this has turned into one big CF....im just gonna leave well enough alone and keep the stock BPV...fook it all to hell! thanks though....i guess....

I didn't mean to be an ass, I just wanted to get across that it wasn't a good idea. You should either run the dual setup (which vents enough air to prevent cavitation/recircs enough air to keep the MAF/ECU reading happy and not give you a rich condition/stall). You can also get a BPV that passes a large volume of air. That is probably the ideal way to run a Maf-based system. 505 has a better BPV than the stock one through Boostsciences. You could also in theory run a dual BPV system if you couldn't find one big enough. There are a lot of options.
