How To: Kill your turkeys

[505zoom]

Excellent work Rich...now it's gonna be harder for me to wait til I get my FMIC! Have you put in the fins in the HKS to tweek the sound yet...it sounded like that clip was done before you put them in? If so, post some clips w/ the fins if you get a chance....thanks again!

The silver fin sounds just like the recirculating fitting, or no fin at all. The gold fin is what I have in there now and it's almost like a squeek added on to the whoooosh. I tried to record it, but the sound maxed out my mic and wouldn't come through.(laugh) I'll try again with the mic mounted further from the BOV.

505: This is some really great work that you've done. I for one, can sleep better at night knowing that my MSP will not always make a turkey noise. The whole turkey BOV/stall issue has been an irritating problem for so many people and I'm glad that someone finally resolved it.

Dex: Thanks for trying this out for the poor man like myself without hardpipes.

For whatever reason, it just won't pick up the whistle. I just shot some new ones and got the same thing. It still sounds pretty good on the clip, but nothing compared to the real thing. I'll get a friend to film a drive by soon and hopefully that will be a little closer to the way it really sounds.

so that final sound clip is of the two vlaves workin together??? hmm i may go ahead anf get a fmic before exhast and intake

 

[505zoom]

Yeah, that is the sound of my current setup. Gold fin in the HKS.

 

[Leadfoot]

yeah, you can just hear the "squeek" , but all in all it sounds great! Thanks for the clip! I'm anxious to see how Dexter makes out.

"After it became clear it was compressor surge, it almost hurt me to hear it."

Does it hurt the compressor? Will this eventually hurt the car?

It's my understanding (those w/ more know-how correct if I'm wrong) that compressor surge w/ hurt the car in the long run, but probably not until after warranty (?) It's basically the turbo spinning backwards (RIGHT?)

 

[jflo]

i think so...check 505's other thread debating on the compressor surge of the turbo and the BOV or something...compressor surge is when the air is reflected off of something and goes back to the turbo. it pretty much will try to make the turbo spin the opposite direction and could screw up the shaft/fins/housing if there's too much of it going on

 

[II-Savy]

O man not good news, so I don't understand how taking away the air box will eventually kill the turbo....? That's basically what we are saying here right?

I hope Dexter figuares this one out with stock pipes.

Taking away the stock airbox is only allowing you to hear what is going on better. The stock stuff just muffles the noise.

Just how bad for the turbo is the compressor surge in our cars? Tough to say, and some people have differing views, but I don't really want to find out. It sounds way healthier now

 

[II-Savy]

Ok I understand. So every MAZDASPEED does it every day no matter what intake you have. I have to think Mazda wouldn't build it to fail.....just like that other guy said, every one would break eventually.

I still hope Dexter or you can find a way to kill the turkey with a stock set-up....with a CAI.

I got Spools hard pipes and an HKS Ssqv and i have no turkey. It always whistles and squeeks, it sounds great.

 

[II-Savy]

LiLiTaLy - So your stock Blow off is gone correct?

 

[LiLiTaLy]

yup sittin in my basement. The only thing is I have the stock intake. Maybe with a cold air the sound would change. Not really sure?

 

[Emode]

and your venting to atmosphere?
do you stall?

 

[LiLiTaLy]

yes i can stall if i rev it out and throw it in neutral. I have only stalled a couple of times. Mostly to blow off for people.

 

[Emode]

also are you running dedicated vacuum lines, for the bov and wastegate? or still the stock hose routing...

 

[505zoom]

Mine would stall very easily when I had the HKS recirculating by itself, and when I had it open-vent by itself. Anytime the rpms were allowed to drop to idle from above 3000rpm, it would stall, or bounce back after hitting nearly zero. This was very annoying, but now I can fully rev it to redline and it just drops back down smoothly.
