Mazdaspeed 3 HKS vs CX Racing blow off valve

Mazdaspeed 3 HKS vs CX racing blow off valve (bov) vent to atmosphere (vta) sound comparison.

[@mrc.4751]

nice comparison, thanks. I prefer the sound of the CX.

[@bigboostmcgee4211]

Thanks, I have a hard time choosing

[@johnvouk5951]

I actually prefer the hks bov with the insert installed gives it a unique sound great video overall but you should have put the insert fin.

[@bigboostmcgee4211]

I prefer the hks without the insert myself

[@leojofish6268]

I bet the HKS is better quality

[@ageagile1047]

CX racing bov 👍

[@TexasVexes]

My build going to be using the cxracing kit. So I have that bov. So glad it sounds decent.
Worst case scenario I’ll buy a real Greddy if this one fails.
Sounds good though !

[@bigboostmcgee4211]

It's also adjustable, I have a video on my page with sounds of the different adjustments

[@geovexil2724]

Cx racing won my heart

[@bigboostmcgee4211]

I'm either running that one or no bov right now.... I love they way both sound

[@jaydaksrules5316]

That hks sounds alot different to mine.

[@bigboostmcgee4211]

I have the insert removed and that makes it sounds different, there were different shapped inserts to make it sound different from hks

[@joshenkocobos172]

Cx racing

[@kerryjohns1485]

I got the hks ssqv on my speed3 plumbed back and it sounds cool asf like fluttering at low boost and pew at 21.5psi

[@timocruze9421]

Hks for sure

[@SrsLe33]

I like em both but our cars hate vta :(

[@xtofux373]

Honestly yea you right. also the CP recirculating bpv with intake is just as loud as these BOV.

[@TreeFiddy-1337]

I had a tune but mine runs great on the Sure Ventus running 50/50 vta/recirc. Great option to look at. Safer than a bov and almost as loud.

[@jaromyoung8471]

I have an HKS on my speed but mine has some turbo skitter to it. I thought that was normal for the HKS blowoff valve

[@bigboostmcgee4211]

I have the insert removed, that's probably why it sounds different

[@geoffgerhardt2454]

Hks sounds way better with a downpipe bc of the stututuu

[@bigboostmcgee4211]

Truly the best sounding is no bov in the video I just put out

[@Dyl_Cam]

I'm trying to figure out if that HKS flange is the same as the turbosmart one. It's wide like that one, but I don't know if its mm off or something

[@novaorbitdragon]

Just me or is the CX high pitched? Any way to get rid of that high pitch sound?

[@bigboostmcgee4211]

Yea, you can adjust the stiffness of the cx racing to make it sound different, I have a video showing the cx racing bov

[@cps178]

did you do something to the cxracing bov? I have the same one but it sounds a lot quieter and doesn’t have the high pitch whistle on mine. Also running vta

[@bigboostmcgee4211]

I have a video showing the different sounds of the cx racing bov, you can harden or soften it

[@0riginalfuz]

just got a speed 3 how did you bypass the stock internal waist gate of the stock turbo?

[@bigboostmcgee4211]

There is no way to bypass the wastegate, just the bov/bypass valve.

[@Issacko2431]

Are you running any turbo or ecu mods or just the bov??

[@bigboostmcgee4211]

In this video it was stock turbo and I didn't have a tuner yet, so just a bov

[@Issacko2431]

@@bigboostmcgee4211 oh ok thanks bro what air intake are you using ??

[@bigboostmcgee4211]

I'm currently using the cobb turbo inlet with a Injen intake, going to be switching up to a custom 4 inch intake for a gt3582 top mount turbo setup soon

[@tstshuffle209]

Do you have a link to the cx racing Bov? Or know where to order it?

[@shaunsnyman5107]

We want sutututu not a woosh

[@anthoniewilliams6325]

I know I’m late but where can I find that cx racing bov? I have the same car. Do you have a link by any chance?

[@bigboostmcgee4211]

It only comes with the intercooler kit, and I got mine from ebay

[@geminigraphics3391]

Not tryna be the odd ball here but Will i have to tune after installing hks on a cx7 or just plug & play? Very interested in purchasing

[@bigboostmcgee4211]

Just plug and play, no tune required

[@geminigraphics3391]

Thanks for replying bud

[@who_k_nows]

where can i get cx racing bov?

[@bigboostmcgee4211]

Ebay, but you need to buy their intercooler kit to get it

[@carlosmontoya8271]

So is the cx racing vta or ricircrm

[@bigboostmcgee4211]

It's vta

[@timgolec8648]

Do they have the same flange?

[@jwuonog]

No

[@eflem7708]

Can you post up a link to where I can buy just the cx racing type s bov?

[@bigboostmcgee4211]

You can only buy them from people who don't want to use the one that comes in the cx racing front mount intercooler kit, like this one on eBay now www.ebay.com/itm/224383976344

That's when I had the cx racing kit, but now I have a new larger custom fmic using the cx racing pipes, check out the video on my channel

[@ericktrejor4011]

where can I get that Blow off cx racing? Only blow off

[@bigboostmcgee4211]

I don't know if you can, but it is a rep of a greddy type s bov. It'll cost about the same as the cx racing intercooler kit.

[@bigboostmcgee4211]

I'd also try finding a used one on ebay

[@colinas_hitman2424]

I recently bought that kit does the hks fit there perfectly or do i need to buy another pipe

[@bigboostmcgee4211]

There are hks bov adapters to convert it to a 2 bolt flange

@@bigboostmcgee4211 is it the oring that seals the valve to the pressure pipe

Ahh ok thanks, I work at a machine shop so I can probably fix it and make it work properly. Hopefully haha. Thanks for the replies

[@raquielcross5757]

I have a cx racing front intercooler and it came with blow out valve..i think it sounds even better than hks from this video, but I already had a turbosmart type which was like 350$ ..so I obviously kept it .just the whole intercooler kit and with the valve had cost me like 280 or 290at the time off of ebay brand new so I kept my turbosmart and sold the cxr..for 40bux😆
