my turbo sucks!
Actually it's the sound i'm annoyed by :giggle:
It's such a loud sucking hiss .. it's as loud or louder than my bypass valve which is currently venting to atmospherre... I put whatever damplifier pro i had left on my hood, (a little over a square foot) but that didn't make ANY difference at all. Would making a heat shield / cold air box reduce the noise? Could i soundproof that?? I used to enjoy just driving around in the miata.. Then i wanted a little more power b/c it was embarassing. Now, i've got enough power, but i feel like a boy racer.. my exhaust is too loud, i have a whooshing BOV, and my intake sounds like a deflating tire! :vash: |
Trade the turbo kit in for a Camry?
|
recirculate your BOV to quiet it down, make sure you don't have a boost leak, get a K&N filter (cheap ones will make more noise than others), and add another muffler to your exhaust, problem solved.

Grow a pair of balls.

Sam, fuck you -- your 1.6L valve cover is still waiting for you ;-) Given enough time i may get bored and start polishing it to see how bad i can screw it up.
I have a begi-s, it hink it came w/a K&N... i will also get a new exhaust at some point, hopefully a 3".. I will be checking for a boost leak once i get my new intake tract.. Thanks guys -Tomaj |

My cold air box reduces the volume of the sucking noise significantly.

Hey,
I'm using this exhaust: Got a deal on an exhaust! - MX-5 Miata Forum Before the turbo, this exhaust was ridiculously loud to the point i was going to toss it, having bought it just a few months earlier! And i found this thread while looking :), seems i'm not the only one who likes quiet! Stock muffler with turbo - MX-5 Miata Forum I'll be looking into the cold-air box... Braineack -- did you build it yourself? if so, out of what? (aluminum, thickness, how much material, how did you join @ the bends - welding?) -Tomaj |
Mine was way too loud also, and I got harassed for asking how to quiet it down. At the moment I have a hot-air intake that isn't too loud but I plan to try turning it into a quieter cold air intake.

i bought some silicone tubing to make a new (straighter) intake... once that's done, it's time to make the cold air box, i'll probably do something similar to this:

if its too loud take it off and ship it over to me. I won't cry about it.

i build "version 1" of my cold air box. it's rude & crude but works, it's definitely a little quieter now. i stuck some leftover damplifier on it ;-)
I bought 2x2 ft aluminum sheet, and cut it in half. I then cut, fit, repeat until it was more or less OK for the bottom end. i then cut the top end by eyeballing the line from the side and marking with a pen.. not ideal, but OK for a rough draft. for the intake hole, i just cut a "U" out as opposed to making an actual round hole (version 2 will have that). I notched all along the edges and folded the metal back to make a smoother edge, then pushed some fuel line onto the edges to create a softer edge. right now it's not perma-mounted with any tabs or whatever, but seems fairly stable because the cutout for the intake is tight enough to hold it tight. Here's a quick question -- i was planning on using some 'hot water pipe' insulation for the edging instead of the fuel line... do you think this foam tube will be able to withstand underhood temps? -tomaj |

^^ Yeah that is a Mega-fail. If I was FM, I would sue for having my name within 10 feet of that car.
If you enclose the filter and/or add some ducting (smooth wall) it will help lower the sound level. Something like a BEGI-style air box would make a difference. |
your car turbo to loud...
http://www.dontgomovement.com/missing.jpg i have a mp62 and it's annoying when it's not screaming at other cars. |

So since we all drive girlie cars, we must make them loud and obnoxious to compensate, show everyone how manly we are. got it.
In the meantime -- I built my 2nd version of the box.. i used the hot water foam around the top to seal against the hood, and the fuel line along the sides and bottom. I'll probably build version 3 in a few months once all the cuts on my hands healed :-D |
