They're both tried and proven BOV's, but I think (and I don't have one myself) the type RS seems like it would be a tad harder to recirculate. The type S just comes ready out of the box, but I think with the RS you are forced to take the horn-thing off

Its always been my understanding that the Type S is just better quality...kinda like the difference between an alpine type R and and alpline Type X...

ive heard that the type s is more prone to leaking than the rs, does anyone know about this?

Type s has probly the best sounding whistle noise when it lets out air. in my opinion

By the way isnt the type RS the new one that recently came out??? i know the type r is the older one but if im not mistaken the type rs is the new one.

The type RS was made to replace the type S. The type S is no longer being made.

so does that mean the rs is better?

Not necessarily. There are ups and downs to each. You just need to weigh the negative for each and see which one is better in the end. Hopefully someone can help you better.

Just get the typeR, I'm very pleased with it.

Type R, Type RS, or Type S ?

oh man i think i am more confused now then i was before this thread haha, because i just recieved the hahn turbo kit i ordered and they are sending me the rs which they billed me for and everything, but i ordered the type s so i am really just wondering if i should cancel it and get the type s like i wanted in the first place or just go with the rs which is on back order right now. Hahn stopped selling the type s

I'm sure you will be happy with either one, just keep it.

thanks for the replies, i think i will probably stick with the rs. Just in case though im going to call up brad at hahn and ask him a couple questions about the two. thanks again!

ive actually had both so hopefully i can help you out a little. As far as sound goes, the type s has more of a higher pitched whistle to it, while the type rs is more of like a big woosh of air. The type rs has a lil recirculation piece that screws right on to the bov which costs like 25 or something around there. The only downside to the type s is that the adjustment screw stripped easily and leakes, which was the reason why i had to switch to the new type rs which for a few months now i have been well pleased with.

where do you have your type rs adjusted to, i cant get a good sound out of mine for the love of it

The Type S goes PSHEEEEEE and is purple.
The Type RS goes PSHAAAAAAA and is blue.

That's about the only difference.

Adjustment does not change the sound. Make it just hard enough to stay closed under max boost to avoid compressor surge.

when i had the type s on my car...adjusting it most def changed the sound, but i guess you would since you had both right?

It's quite a task to get the perfect middle range of hard and soft when adjusting the RS. I've been adjusting for a few days and i'm still lookin for the perfect spot.

Ok, allow me to rephrase. Adjusting is not intended to change the sound. If it does it's only a side effect to its primary purpose. It is to adjust the level of compression on the spring inside the BOV so you get to the point where it does not blow open under boost yet does not remain closed after you let off the throttle. The purpose of this is to provide performance and prevent compressor surge. However, I guess since you are adjusting for sound, performance is of secondary importance to you.

No skillz is right...the primary reason for the soft-hard settings is to change the setting of the spring to prevent compressor surge usually noticed by the fluttering sound. You are not gonna get the same sound like the type s from the type rs, ive tried many settings just for the sake of trying i guess. but yeah overall the type rs does pretty much sound like a big burst of air, no unique sound to it and no high pitch like the type s. on the type s though the softer u went the more louder the high pitched sound went, so u can try going softer, see if that helps ## sound if its bothering u. as long as its not fluttering then id say ## pretty much good...sorry for the lengthy post

I'm going to be throwing the Greddy Type-S on to my car from our broke VR-4. It was really loud on his car with all stock piping and just a cone filter. I'm really curious as to how it'll sound on my car w/ all hard piping and no silencer before the SMIC. I'm going to paint the adapter and the bov first before I throw it on, don't wanna go through referee again.

I currently have the Greddy Hard Piping for my 2g with the Type RS, and I can't complain it hold so much better then stock. Sound really isn't a factor for me. Mine flutters just a little bit under low boost, or doesnt blow off at all at like 2500 rpm shifts, well in that area atleast, but at high boost it sounds nasty. I wish i could have got the type s though. sorry to side track but i like the rs. if anything cup up the greddy hard piping and get an HKS Flange and the HKS SSQV Blow of valve if you going for mainly sound or get the TurboXS RFL (Real ####ing Loud) Blow off valve and Piping.

ok i have mine and it does a lil fluttering sound at i think low boost levels but when i get a bit aggresive its that nice pshaaaaa sound. Ok as for the fluttering is that good or bad? what do i do to change that? which setting soft or harder? im learning this aspect so please help me out overall im very satisfied with the type rs just need to learn how to adjust and why.

im into the performance aspect as the sound is secondary, BUT i do need to know what sounds are good and bad meaning is that fluttering when i let go of the gas like at 2500rpms good or bad, do i need to adjust to hard or soft? sorry for repeating myself as i really want to figure this out and set it to where it needs to be
