I had the Raptor on my TN set-up and now I have the RFL on my Greddy set-up. I like both, but I absolutely love the wooossshhh of the RFL. Blowing off at around 9-10psi the RFL is way louder and wosshes more than the Raptor-at 13-15psi its just nasty. All personal preference....

 

rumor has it that HKS is releasing there NEW Blow off valve this month in about 3 weeks. i think ill wait for that to see it before i start changing valves again...

 

thanks for telling me that..

 

i heard the quality of an RFL isnt that good, have you had any issues with yours alberto?

 

The ROFL works well with Alberto's setup because he's running 13-15PSI... With the TN setup.. I'm a bit afraid of the our 8-10psi not working with the bov.

 

Any BOV will work with the right tension spring in there. Sound is a different story though. Tim from SpeedForce has a Turbonetics Godzilla BOV on his car and even at 11-13 PSI of boost it barely makes any noise when it blows off. The valve is operating fine but its a 50mm BOV. You need a LOT more airflow then that to make it really loud...

 

why everytime i see the title of this thread.. i see "an FYI on Little BOYS"

 

im thinking of adapting the HKS BOV on my turbonetics, think ill try it out tomorrow haha... wonder if it will be louder than the raptor.... anyone have any idea?

 

 

so, today i had my mechanic who does all my work customly adapt an HKS sqv BOV to my turbonetics kit... and let me just say OMG, it sounds fricking amazinggggggg!!!! highly recommend it!!

 

i hate my RS...i want my BOV to sound like this:

Yup HKS SSQV... I'm glad someone likes it...

 

love em man.....i may either go with that or (if my dreams come true and i find one) an old Greddy type-s

 

you can find a Type S on ebay.. authentic

 

i wanna get one from someone I trust...i don't have a problem with ebay but i'll wait til I can find one on these boards or thru a friend

 

How much work is involved and how loud is it compared to the raptor? I would like something a little louder than the raptor..

 

For some reason, the HKS sounds awesome on the supra but when I had it on my STi, it became a little annoying and it wasn't that loud at all but on my brother's supra, when that thing blew off, my ears would hurt. lol

 

i'm going to replace the outlet of my BOV with a 29mm straight aluminum tube and see if it will replicate the sound of the Type-s...i will post up my findings

 

did you try the spring mod I posted for the RS? it adds alot more sound to the RS by letting more air pass through the valve before it shuts.

 

Yea it's a bit hard to replicate those insane sounds when we're only running 8-10psi lol.. those guys are all running like 15-30psi!!


Noahz are you welding and messing with the gunmetal finish on the pipes? That's the only thing i'm afraid of..
