Tsss sound when changing gears?

[Blender345]

Okay, don't make fun of my newbiness when it comes to cars but, a few months ago, more like last summer, this guy in an import (not susre what it was) had a pretty cool car. I was in my friends car and he was comming up on us. Everytime he switched gears, it made a Tss sound, like a hiss. It sounded awesome (imo) and was wondering what it is. Nitros? I don't think it was a supercharger because it only made the noise when he switched gears. It looked like he put a few bucks into his car so I have no idea and am hoping one of you might know. Thanks.

blow off valve from a turbo?

[Blender345]

No I think it was meant to sound that way... like a cool Tss like nitrous or something. I don't think anything was wrong with it.

[Trickyslick]

It is called a Blow Off Valve like stated above and it releases pressure when you change gears. I like the sound too, my buddy has it on his eclispe.

[Blender345]

Oh my bad I thought you meant he blew off his valve (as in a bad bad thing lol). I am a newb. How much are those? I loved the sound too.

[Bad99Olds]

haha wow. ok. a BOV (blow off valve) is used to release excess pressure in a turbo system. you would need a turbo system to get the bov. they make fake ones, but its utterly pointless.

[alerojack]

to get the blow off sound you need to turbo your car. if you want to go the cheap route and just get boost and no motor build you would be looking at around 1000bucks. but thats getting used parts and not building the motor. (1000 if you have a 2.4, not sure about the v6, im guessing much more?)

[Trickyslick]

ebay has them for like $50 on up...look around if you have the rest of the stuff for it.

[Blender345]

okay so to get the BOV I need turbo... and the cheapest turbo for a 2.4l (what I have) used is roughly $1000? Just want to get this straight to make sure I am not going to get it lol.

[[ion] C2]

haha google up information on turbocharger systems, what parts are involved and how it works

[FrankTheTank]

i thought there were electric bov's being sold somewhere on the interweb?

[[ion] C2]

ya a speaker tied into when you shift LOL

my car makes a sound similar to a BOV when the throttle plate opens and closes, it's a loud pshhh. i can make it sound like it blows off when i shift lol

[Blender345]

what do eletric ones do? just the noise?

[Bad99Olds]

yes, just the noise

[Blender345]

Do they have this stuff for alero's? I can only find em for like civics and eclipses and wrx's. just wanted to see prices.

[Bad99Olds]

dont know, just go turbo. lol. it will be even cooler than you can back up that cute tsss sound.

[Blender345]

thats what I'm talking about. Where do I find a turbo kit for an Alero? I only see imports... for both a turbo system and a BOV.

[Bad99Olds]

what powerplant are you running?

[Blender345]

lol... powerplant? what the hell is that? All I know is that I have a 2.4l engine 1999 Alero. lol.. wow I'm sad eh?

[CiscoPath]

You might not find a whole lot of listings for Alero (or any at all). But search for Cavalier/Sunfire (both run the 2.4) kits, and you should have better luck.

engine...powerplant....motor. Generically the same thing unless you're talking to an anal-retentive gearhead

[Bad99Olds]

haha by powerplant i meant engine. not sad, its a learning experience.

link the the supercharger sticky in the 2.4l forum. you have the 99 which poses some problems i beleive, but im no expert

[Blender345]

no website links I can get? I don't get why it's such a pain to find a site with a turbo system with a price attached lol... I'm guessing you have to buy a BOV seperately?

[Bad99Olds]

www.gmpartsdirect.com

GM PART # 12498660

[Bad99Olds]

but really check out that link i posted a few ago, its the whole thread about the supercharger

[Blender345]

Thanks guys and sorry for being a pain in the ass... I've been wondering this for a long time and now I can sleep better at night lol.

[Bad99Olds]

haha no appology necissary, again, its all about learning, and ur helping me pad my post count. nice.

[cherrington17]

Thanks guys and sorry for being a pain in the ass... I've been wondering this for a long time and now I can sleep better at night lol.

we all started somewhere. at least you can admit your noobness. :lol:

and indeed, BOV sounds are amazing.

[Blender345]

That's why I want one so bad but I can't afford a boost system and would feel dumb if I got a fake one (which I haven't even seen after all of this searching on google lol). But again I am very happy to be a part of this community, you guys are more than helpful and patient and understanding.

^gives good view of blow-off valve

[[ion] C2]

that's because no one makes turbo kits for the LD9 (2.4L), you have to piece it together. www.j-body.org has lots of information on boosting the LD9.

like i said, google and figure out how it all works, www.howstuffworks.com is great for learning about how engines and turbochargers work

[Blender345]

thanks guys.

[[ion] C2]

the resource i'm making will also explain things in detail pertaining to forced induction including parts lists upgrades etc.

[meadus101]

Go for the GM supercharger. It's more of a Bolt on.

[Blender345]

I can't afford anything like that. If it were a couple hundred then no problem, but over 1k is a bit excessive for me and my car isn't in mint shape... could possibly die anyday having 150k miles on it. I wish I had the money to not have to worry about it but that isn't the case. I just loved that sound and I'll have to keep dreaming lol.

[whiterider00]

i wouldnt worry too much about the car dieing, especially the engine. ive got a 2.4 with over 160k and the engine is fine, and [ion] has the same engine with over 180k (if i am correct) and hes got a s/c with no major problems (again if i am correct). so dont be afraid of the high milage, these angines r pretty damn durable. good luck with the car.

[Redog]

I kinda doubt the ricer you saw that day had a turbo, just the BOV

You are talking about turboing the car, for the sound? Makes on sense to me. You turbo or s/c a car for the speed. Ricers get different BOV's to sound louder becasue they want EVERYBODY to know that they can't drive :lol:

The S/C kit listed above would be your best and cheapest bet. Bolt on, reprogram, and go ;)

[cherrington17]

:glare:

yeah.. because its TOTALLY unlikely that an import can be balls out modded. that just NEVER happens.

ken.. your starting to show your american ignorance....

[[ion] C2]

Yes he is, haha. A lot of import vehicles are turbocharged with a blow off valve. I've never seen one with a fake one yet. So a loud blow off valve means you can't drive?

BOV import oh noes: http://youtube.com/watch?v=RM1sGPwVSrU

LOL as long as you dont beat the hell out of it (like i did) you will be fine.
Mine only had 106 k and had rod knock. You can always save up money and do it little by litle till you get a nice set up. Also if your worried about the motor you can order a crate motor and put a new one in. ( i do think they run over 1k but if you look around you might find a deal) also you dont have to buy a kit, Buy piece by piece on line like ebay or something and you can get a whole turbo kit pretty cheap depending on the turbo you use

Ken, I see sooo many cars these days that actually have turbos, so it's not that far-fetched (thank Ebay for that). However, I totally agree with you about turbo just for the sound of it.

Chris, I'm a little upset with you. One thing to defend ricers, and one thing to attack your fellow Aleromodder.....but where the FUCK do you get off stereotyping Americans as ignorant, and if you're that ashamed of being American where you can't even capitalize the word, by all means, move to another country (you have the freedom to do that, remember?) where you can be proud to be one of whatever they are.

Yeah, we all know there are a few idiots out there, but to slap that label on as a generalization, you truly disappointed me for the first time. This place is getting rediculous.

-BlackJack- OUT!

[cherrington17]

^ i was referring to "american" as domestic cars, as apposed to import. Not referring to nationality of the poster. sorry to not clarify. :banghead:

My name's Chris too. Funny you thought he was steroptyping against his own country, LOL. I knew he was talking about the "american muscle/domestic" concept.

[Blender345]

I didn't want the boost just for the sound, that would just be a benifit. I can't afford one right now and would take me forever to save up (especially because I'm in school and will have loans, I HATE being in debt). I dunno I mean if I could do a little something for a few hundred I def would... my car is 100% stock but I just bought an intake off ebay for like 40 bucks... any other mods you might suggest are appreciated. But I would rather not spend more than a few hundred. Plus with the s/c don't you need to upgrade your engine and stuff? I am a newb when it comes to cars, I can't even find a 2.4l turbo on ebay lmfao. Only 2.2's. Gayness.

[cherrington17]

if your going for a system, upgrade the alt.

if you want better mileage/hp upgrade the TB and exhaust.

[[ion] C2]

lol they don't sell engine specific turbochargers you have to know which one to get, it's the exhaust manifold that's completely engine specific

you need:
- bigger injectors
- t3/t4 turbo (common choice)
- 2.4L LD9 turbo manifold
- new downpipe
- wastegate (if not included in above)
- intercooler
- charge piping
- blow off valve
- TUNE

[Blender345]

whats a header good for?

[cherrington17]

better flow from the engine to the exhaust (i think)

[Blender345]

does it increase hp or mpg or anything?

[cherrington17]

hp, i believe.

[Redog]

I never said that imports can't be tuned and be fast, but all the imports I see around here, have boost gauges and an obvousily fake BOV.

Have you ever see a turboed Civic run 18's in the 1/4 mile, neither have I, but I see one making that BOV noise, only to see the car in the pits with the hood open. Guess what, NO TURBO. That is a ricer

Back OT

Turbo kits for LD9 and the LA1 are all custom. They can be done, but it's probably cheaper (and a lot less of a headache) to just get the s/c kit, right from GM ;)

[Blender345]

is it worth getting even if I'm only doing little things to my car? (all stock with new wai soon). I would like to upgrade my car to which I can afford it. I can't believe an exhaust system is so much. like 5-600? My friend said he paid like 150-200 but that must have been just the exhaust? He has a flowmaster on his charokee (sp?).

[cherrington17]

depends on car, depends on mechanic, depends on parts, depends on the deal.

ask around to find out if anyone "knows a guy" or if there are any good exhaust shops around...

i'd probably start out with other, smaller stuff, until you get the "hang" of modding your car, and also by then you might have heard some info about locals where you can find a deal.

[Blender345]

well my problem isn;t with installing the system, it's the parts themselves. My friend had our other mutual friend install his exhaust... but the exhausts I see run like 500 compared to what he claimed paying 200 with free install.

[Redog]

Well if you are going to do a S/C system, I would do the exhaust now (headers back) and if you are going turbo it's pointless to do the headers now,(but you could still do cat back) becuase you are going to replace them with the kit anyway.

Figure out what you are going to do first, then save your money and do it ;)

[cherrington17]

basically.. research, research research. :lol:

[Redog]

^^ Very true.

More time you spend reseaching, the less money you'll spend in the long run.

You have a powerful tool, use it ;)
