k @ n makes car vent

[logans dad]

I looked for 2 hours but no luck on this. Put k and n air filter on and i know this gives me more air but when i shift car vents , am i losing hp? it doesn't feel as fast but just got the car and never had it at the strip yet. it is stock t25, who ever had it before me put a header ex. manifold on it, its comming of by the way i just need to find a stock one. i didn't think this car ran like it should when i bought it but i had to have it. oh by the way its a 98 red gsx. the car had the stock air box on it and it didn't vent with it. should i put it back on until i do like bov 1st gen and boost control? i got beat by half a car length by some little none turbo ed Honda. . i need help! the old man.

Your post isn't making any sense to me. There's really no way the air filter can "vent". It's one way mainly because the turbo is always spinning making it a one-way deal. Are you sure it's not the bov? Can you tell me what a header exhaust manifold is? You either have headers or you have a manifold. Maybe you have a tubular manifold? If you had the stock air box, how do you know it wasn't "venting" then?

yes it is making it vent i think thru bov, its kind of a neet whisle sound when i shift but i want performance and i guess what i need to know is does this mean my bov might be bad. or it will run better with stock air box.

header is tubular.

 

[ADrewzki]

The bov is supposed to whistle like that. To put it simply, when you shift your turbo is still drawing in air but your throttle plate is closed. The air needs some place to go, hence the need for a blow off valve. The 2nd gen ones are supposed to leak a little bit at higher psi so there's an offchance that you are leaking a little bit of air but it doesn't mean that it's bad. Turbo cars have manifolds. Turbo cars have manifolds. Turbo cars have manifolds. You have a tubular manifold. I didn't think they made tubular manifolds for a T25 to bolt up to.

exhaust is a pase setter header and when i had the stock air filter on it u coundnt hear the bov venting.

 

[ADrewzki]

For the last time, TURBO CARS HAVE MANIFOLDS. Quit saying the word "header."

And if it bothers you so much, put the old air box back on and see if the problem still exists.

i knew this would happen, someone getting pissed, i said it has a, ok, after market exhaust header, it is a pace setter header what dont u understand about that. and i know air cleaners dont vent, u should know they dont vent, sry i messed up ur day, maybe someone else can help, i just dont think by changing air filter it would make car vent loud, im knew to turboes but a stock car i didnt think would vent even with after market k and n air filter! and yes i also know what a exaust manifold is and a header!! this has HEADER on it.

 

[spoolin27awd]

OK man there is nothing wrong with your car the k&n filter is less restrictive and with that the bov noise is not muffled as much so you will hear it more especially if you took your air box out and are just running the filter

ok, thanks, and tnk u also Adrew. i still think car is a little slower then what i think it should be but its getting a big 16g this summer with the mods i need to go with it, i should say this car is fast thru 2nd gear but then is a dog. must be from the little t25 turbo.

 

[mavisky]

Look you're hearing the venting noise now only because the air filter allows some of the sound waves to get out. Before the factory airbox kept you from hearing this noise even though it was there.

You have a Pacesetter turbo manifold, not a pacesetter header. It's a tubular manifold, but that doesn't make it a header.

 

[marcmsj]

point being...

as long as your bov is being recirculated back into your intake, then that "neet whistle" sound is normal..

and you have a manifold dammit..

(made me laugh though)

 

[HighPsi92GST]

I love this thread

Sounds like you have other problems if installing a k&N made your car slower

 

[CyberEye]

I'm sure it's sead before, but whatever. Yes the K&N is the reason you hear your bov venting, it vented before you put the K&N on it, you just couldn't hear it because the stock filter/aircan is so restrictive. There is nothing wrong with hearing your car venting, it's not causing any problems.

 

[ADrewzki]

! I think I need more green bars by my name sometimes.

 

[Sic95gst]

Ok "venting" is pushing the air out of the BOV into the Atmosphere, when it's hooked back up into the intake we call it recirculating. Yes the valve is venting but back into your intake. It makes that sound because it's letting off compressed air very quickly and you have a high flow filter which lets the sound pass threw, unlike your OEM air box. Don't cry because people are correcting you, they just don't want you to sound retarded when you talk about your car.

tnx for the help. but i need to say i went to ebay and they call my header a turbo manifold header! we were both only half right .

 

[HighPsi92GST]

you call it a pacesetter header, others call it pacestter manifold, I call it JUNK.

 

[tonygst]

yah i didn't know if those pacesettler manifolds hooked up to t25's?

But i guess they do. WTF

 

[Attack Eagle]

of course they do...

they bolt up to any turbo with the standard DSM manifold to turbo bolt pattern... and despite everything that is wrong with it the T25 is a DSM stock turbo...

 

[logans dad]

been thinking, first off adrew says i said air filter is venting. i know a filter doesnt vent and its the bov, next, if u come to iowa and a group is by my car and u say my pace setter header is a manifold they will look at u like u are stupid. When i got the car and went up town some srteet racers were in a parking lot and i pulled in, they asked to see the engine, all of them were like man check this fricken header out!!!! maybe its a thing in your area to call it a manifold, iowa has more race tracks then anyother state and when we see a tube comming of the head its a fricken header, im 49 years old and when its cast iron its a exhaust manifold, what is the big deal here,Adrew, are u a young kid and dont know what a header is, ok i will call it a TURBO HEADER, but not manifold .i think it must be a slang. what my post was mainly for is to ask if im losing hp with the venting, The car didnt get slower after the k&n either, about the same. i will just drive it untill i mod it and not worry about it, it is a dog tho after i hit 3rd gear, must be the little turbo, crap i think i answered my own ?

 

[Bigglesworth87]

Ok, if your 49 years old and are used to working on race cars then you must be working on classic mucle cars without turbos. If you look at your chiltons manual (assuming you have one for this car) then look at the parts list and read what it says. It will say TURBO MANIFOLD. A car that is N/A (Naturally Asspired) will have a header and dont believe everything you read on EBAY. The people that post those adds put random words in it so that it will have more hits. Take a picture of your setup and we will figure out if you hooked it up wrong. When you say venting your making all of us think that your BLOW OFF VALVE is venting, but since you are talking about a K&N air filter you are probably hearing your turbo spool up from inside the car. Since your car is AWD (all wheel drive) of course its going to seem slow in the higher gears, its not a FWD (front wheel drive) car.

 

[logans dad]

thanks biggle. that makes sence to this old man.

 

[HighPsi92GST]

49...by the way you type I would have guessed maybe 7 or 8 years old at the most.

As for the manifold, no it is not just what certain areas call them. They are actually called manifolds. And pacesetter is junk, so yours isn't even really a manifold either, just junk.

 

[Bigglesworth87]

OH and just to clearify something. They are not calling your car crap/junk, its just that pacesetter doesnt have the best feedback. It's the Ford Pinto of manifolds. The walmart brand of car parts.
