me and my freinds got into a discussion on which is the loudest blowoff valve for a z32. so which blow off valve is the loudest? give me some output!

 

Ive heard a BOV from HKS on a guys 96 TT. He was driving behind me about 3 cars back and I could hear it blasting. Needless to say I was amazed , So I would say that is a really good one. I hear BoostX has a pretty decent one but I haven't heard it in person. But the HKS one is great so I'd say that one.

 

ok, so what is the point of having a loud blowoff valve?
Is the loudness of it equal to the coolness factor?

 

I really hope not. This is a Z32, not a Civic.

 

Duuuuuh Rizz. The louder it is the faster the car goes.

 

That's right.....I forgot all about the ricer school of speed....loud = fast.

 

well if that's the case why not go the sticker route?
last time I checked stickers were much less expensive than blowoff valves, just as cool and proportionately as valuable for speed.

 

Doesnt a blow off screw up your A/F ratio, suppose to use a bypass instead is what I thought?

 

It messes with the MAF being that the amount of air it expects to have coming through isn't. I think the guy was just asking on input from experience, i don't know if he wanted to put one on his car. if you do, consider keeping the stock recirculation valves. they take the excess boost and put it back into the intake side of the turbo....not a bad plan to use that excess boost later to keep the turbine spinning nice and quick. if you're stuck on a BOV, try these following as far as loudness + quality....greddy, HKS, and a blitz is pretty loud.

 

Agreed. You don't need a BOV until you're running massive boost.

 

jeez jeez, sorry I just heard the HKS was a good one, and it sounded cool when i heard it. Man, became a big ol "bash orange" fest" Lay off guys

 

we're not bashing you, lol.
we're just letting ya know what we think.

It appears that the loudest may be the Turbo XS RFL's.

 

There is a recirc kit for the HKS BOVs BTW. I purchased BOVs because I hate that "goosehonk" sound that the stock recircs make when I boost. Anyone else experience that? Some people hear it, others don't.

 

I've heard of the goose honk, but never actually heard it.

So, does that HKS kit allow you to mount them in the factory recirc valve location?

Pictures?

 

Yes it can be mounted it to the recirc location. It came with instructions but are all in Japanese. I was going to try and have them welded to my hardpipes as it's supposed to be more effecient that way. I don't think it would make much of a difference though. Im going to follow a write up on 3zc.

 

BTW heres what it sounds like. Everyone asks if there's something wrong with my car. http://www.streetneeds.com/uploads/v...Picture070.MOV

 

Damn dial-up. Oh well, I can imagine that would be annoying.

Were you able to get everything back together with the HICAS eliminator install? Did you notice a difference?

Have you tried to install the IC's yet? Job doesn't seem that bad. Worst part is modifying the mounting bracket; which is easy. I should have mine in this weekend.

 

Yeah I installed the eliminator a couple days ago after my replacement ball joints came in (finally). I havn't driven it yet as I will install the sub frame spacers now since the car is still on the stands. I will tackle the ICs when I get that done. What sucks is I have to do the work outside and it's been snowing. I live with my parents and the garage is full of my dad's tools and stuff. Go ahead and make fun of me now BTW have you noticed any difference with the spacers?

 

OK, I'm done laughing now. The spacers make a noticeable difference. Wheel hop went bye-bye.

 

Getting off topic but here's a pic of my eliminator install and might as well show some of my car. Not very good but the only ones I have at the moment.

 

So, besides breaking that piece, how hard was that job?

 

Pretty easy. The hardest part was removing the bolts from the failsafe valve and installing the bypass tube as one of the bolts are hard to get. After that I removed the tie rods from the ball joint piece then unbolted and removed the Hicas assembly. Then you just attach the tie rods to the Stillen bar and bolt everything back up to the car. The included instructions were pretty straightforward.
I also installed my sub frame spacers today. It's the easiest mod that I've done. :burnout:

 

I always thought there was something wrong with my car :rofl: I drove a friends 91TT and never heard it.

 

ive heard the goose honk. i thought maybe it was just me. thats the best way to describe it too. a goose honk with a little chirp to it. well i used to get the goose honk...til i trashed my z. 9800 dollars worth of damage ahggg....
