no bov noise
 

kind of a gay question but why is it that some cars will rev it up and they'll make boost and you can hear the bov .. my cousin's makes no bov sound or no boost when reving it up .. just curious as to why it does this ??? only high boost will do it maybe .. he is pushing 8lbs on a .48/.49 i read alot of people say that its becouse no strain on the motor .. but why do some cars do it and others dont ... Thanks

Re: no bov noise
 

is it A/T or M/T ?

Re: no bov noise
 

lol m/t

Re: no bov noise
 

it because there isn't a load on the engine but with a small turbo some are able to build boost in nuetral. if you really want the sound when not moving. use the ebrake and put a load on the engine

Re: no bov noise
 

reson im asking because my friend has an 9-3 Saab A/T. it makes a really nice sound when he lets off the gas when driving but when its stationary it makes a very gay sound that noone can hear.

Re: no bov noise
 

The reason why his saab does not make a noise is because the saab's BOV does not vent into the atmosphere thus the loud sound, instead, it is recirculating the compressed air back into the compressor intake thus the almost silent "gay" sound you may hear. Saab's use a plastic Bosch "bypass" valve. Hope this clears up the confusion.

Re: no bov noise
 

lol come on man do you think im that stupid ? ? ? i took the stupid hose off when he got the car. like i said it sound nice when he lets off the gas, but when its in park it makes that gay sound. STAY IN SCHOOL AND LEARN HOW TO READ :4

Re: no bov noise
 

my bad, no need to be pissy man! I can read perfectly fine FYI! You did not mention that the hose was disconected. just giving a little info to ososlohatch.

Re: no bov noise
 

That is not good an a MAF system. When you unplug the hose, all of that air that you are releasing to atmo was monitored by the MAF, and it thinks it's going in the engine. You will run rich while doing that. Go to school to learn what you are doing before trying to make SuPa TizzIghT MofoCKin PSHhhhSHHhhh sounds.

i dont give a ----. ITS NOT MY CAR he wonted the so ---- off

Re: no bov noise
 

You are a dumbass. WTF does is matter if it's an AT or a MT. When in nuetral or the clutch is in, the engine is disconnected from the transmission in both cases.

This guy answered your question:


After I just owned your ass, please in the future try to read up on how engines, transmissions, turbos, etc work before posting ---- like this. After your recent posts we all see that you are a newb. Show respect and STFU.

Re: no bov noise
 

wtf im just saying what i know. im not a master mechanic or anything like you guy claim to be. and the only ass you own is your moms. dont ------ talk like that. thanks tr4cti0n.i55ues ill let my friend know.

Re: no bov noise
 

Again you show no respect. I only talked ---- on you because of your last post. If you hadn't have posted that ---- then I would show you respect and help you out. See how it works? If youdon't I'm sure plenty of people will lend you a rope.

:y

Re: no bov noise
 

my bovie makes noise

Re: no bov noise
 

Bitches figth and naagg like that. Chillllll outtttt. Lets all talk from our mouth not from our anus :6

Re: no bov noise
 

i blow off in neutral :8

Re: no bov noise
 

in an auto car you have to spin the torque converter. the weight of that can act as a load on the engine and help the turbo spool while in nuetral. im sure it wont spool much but it might be enough to build some boost and make the super tyte jdm psssccccchhhtttt sound.

Re: no bov noise
 

I have both and the stock clutch and flywheel weighs more than the stock torque converter by about 6lbs.

Re: no bov noise
 

my does it when im standin still just rev it up a couple time it should blow off

Re: no bov noise
 

that doesnt seem right to me. i havent acctually weighed either of them but i am pretty sure the torque converter is heavier plus its full of fluid when its in the car

Re: no bov noise
 

Pretty sure? ::) I weighed them both, the clutch and flywheel weighs 6lbs more. Maybe they weigh the same with the fluid inside the torque converter though. I don't know how much auto fluid weighs and I don't know how much fills up inside the torque converter.

Re: no bov noise
 

im sure its a little more than fuel which is about 8 lbs per gallon. i am also taking a guess but i would think about 1.5 qt when running inside the converter. i may be wrong and if i am its no big deal, i have been wrong before, but i am pretty certain a torque converter is heavier

Re: no bov noise
 

small turbo = neutral blow off.

Re: no bov noise
 

i geuss a 48/49 t2 isnt to small for a d15 mini me after all

Re: no bov noise
 

No offense but, ARE YOU A ------ RETARD? :1 I told you 1,2....2 times now that I weighed both and I'm telling you that the torque converter is lighter. :6

Re: no bov noise
 

Just because it weighs more does not mean it creates a greater load. Any dumbass should know that its harder to move a fluid system than a mechanical system due to greater resistance in the system, weight has verry little to do with it. Furthermore the actual tourqe converter casing is not rotated and therefore that mass does not create any load on the engine. Go back to highschool Physics you might learn something!

Re: no bov noise
 

You are also a retard. The entire torque converter in fact does rotate. The torque converter housing rotates with the crankshaft. The stator is connected to the transmission. In nuetral the torque converter housing is rotating with the crankshaft and the stator is forced to rotate with the housing. Inside the auto trans the clutches and bands are not engaged to provide power to the wheels, thus freewheeling. Also the physics you take in high school would not cover anything complicated about fluid systems. Only some basic stuff, if that.

Re: no bov noise
 

the whole converter does spin. you bolt the housing to the flex plate. i also did consider that the fluid will create resistance but i am so far from any type of chemical engineer that i would just make myself look dumb. i am almost certain it takes more effort to spin that converter. if i had the time i would look some info up about it
