its carbon fiber, i got it off teh bays a couple years back, its got hairline cracks from the hail now and the gel coat has oxidized from the texas heat but it fit pretty decently the company was called key composites group, i had bought an s13 hood from them prior to this one and was impressed with its magnificent fitment...im not sure if theyre still around or under a different name now

 

ya they are in MD, I always thought that was a good design to remove heat, but was wary of the fitment

thanks

 

That doens't look like a vortech BPV. That' looks like a blow off valve in which it sounds like when you are boosting it isn't staying shut and leaking off.

 

youre right...the pic was when i had my bpv off when i was waiting on the parts to come in to rebuild it so i had another bov sitting around just to test out and see what it would do just to see if i got any different results, it does seem like it must be staying open but i havent tested with it blocked off cause i dont wanna hurt the compressor...but i guess i may have to bite the bullet...does anyone know if my vaccum routing is correct? i posted it a couple replies back for someone that inquired but they didnt reply

 

The blower wont' function correction with a blow off valve on there. A bypass valve works in a different manner. The pressure could be opening the BOV causing a massive leak.

 

...yea and I've had the Maxflow on it since my last test. Where it measure 3psi. Like I said it was just on there for a picture to show placement and what not and to just try out while I was waiting on rebuild parts for the maxflow

 

just wanted to bump this for more opinions and tell yall that i drove it (cautiously) with the bpv vaccum unplugged (with a bolt in the hose to block it off too) and i had compressor surge but i had to test...still no boost, so the bpv isnt the problem...still no leaks anywhere...im gonna call vortech today and see if they can bench test my blower...this is crap...you spend a shiiiit ton of money and then it doesnt work...i know i installed it correctly

 

have you tried mounting your boost gauge right on the blower?

 

I have not tried that but figured it wouldnt make a difference, because if i was loosing pressure somewhere its still going to measure the same amount of pressure whether it be at the manifold or at the blower, if its not building pressure in one spot its not gonna build pressure at another...its just fluid dynamics ya know? but i suppose if it did work it would tell me whether the blower is bad or not...but then id have a hole in my piping that i dont really want

 

You are correct, it wont make a difference if you mount it closer to the blower.

 

bump **** my life...still no results, still no news, i put a new pipe in place of the pipe with the bov on it, ran like **** and only made 1.75psi...possibly ran like crap due to the fact that its been making no boost for a while now and has probably ruined the plugs...i seriously need some help guys...if anyone knows any shop in dfw that can fix this and figure it out without me having to give them the car to fit the bill id love to know...

 

Jtran but i think he is outside Houston

 

ugh...yea the furthest id consider driving it is 50 miles right now...and im in lewisville...it was being tuned at awd tuning but since theyre really a subie place they had no idea what was going on lol not to say that they arent great guys, theyre just used to their turbo fours

 

Ughhh, you didn't think to just get another bpv? Or I must have missed something...

That would be the best bet IMO

Either way, nice s14! That looks like a super fun car to drive! You should get some long tube headers and cams! Once you get this issue solved....
Check out Hotel Crazy's exhaust setup on youtube (the megan racing longtubes + motordyne true dual shockwave). I'm sure if you wanted, Motordyne would build a system for your car, and it would sound UHMAYZING.
Back to topic; get a proper bypass valve.

 

well that was our initial thought as well, but i really dont think its the case, theres no bpv on it at all, just a replacement pipe. it made 2psi. with the bpv unplugged from vaccum it made 2 psi. with the bpv operating "correctly" (<--as far as i know) it made 3.26 psi...im beggining to wonder if there could be something mechanically wrong with the engine for this to happen? thats really what im dreading, but i cant come up with another explanation thus far...as far as it goes though, the blower is supposed to be pushing 8-10psi so says stillen, if i had a leak it would push past it and wouldnt make any pressure, but i dont have a leak, so pressure would be building regardless because the blower is going to pump and pump AND PUMP until i shift and lower the rpm again causing the blower to spin slower again. so even if i did have a valvetrain issue or something of the sort the supercharger would still be forcing air into the cylinders and causing an increase in pressure, unless the exhuast and intake valves were overlapped for a dramatic amount of time, then the pressure would leak through the open space and wouldnt register...so im thinking this may be the deal...i really hope it isnt, but i may have to tear my engine down to inspect my timing...this actually makes the most sense of all of it...but if someone can clarify this with me thatd be great, if cam timing was off by one tooth...it wouldnt bend valves or affect how it ran, but it could result in a loss of power and severly overlapping exhaust and intake valves that would lose compressive power...i think this is my issue hands down...that sucks...what do yall think?

 

i forgot, did you seal this up and do a pressure check on it?

 

By any chance are you running a catch can that may have a one way valve reversed or a pcv reversed.

I would check all connections to your intake (brake booster valve) all hoses
and I would also do a compression check you might have a hung up intake
that is bleeding off boost.

2nd is more involved but try to disconnect your intake tube AFTER you MAF and use a compressor (air) line to blow into your intake ( be sure to regulate the pressure below 25 lbs and see where it is leaking off..

With both of these tests I would think it is a compressor(supercharger) issue..

Sorry for all the grief you must be feeling and good luck.

 

If it was cams and valves to the point where you weren't making boost, you'd notice some very serious problems while the engine is running.

I'll come back and re-read this when I have more time. I still am leaning towards the bpv, but I don't quite understand where you are measuring the pressure (why I'm coming back to re-read). GL man

 

your intercooler pipings must not be connected, this happened to me before, if its leaking you wont have any boost

 

Have you done a boost pressure test?
