Description

RallySport Direct is proud to carry the Go Fast Bits TMS Respons Hybrid Blow Off Valve. This makes for an excellent upgrade over the stock blow off valve to hold more boost and to have a quicker response.

Here are the key features:

Patented adjustable venting bias system found in the Stealth FX system
Allows you to control the amount of air that is vented to the atmosphere, or recirculated back into the intake to control the venting sound based on driver preference
You can achieve a vented blow-off valve sound without triggering a check engine light or other problems such as running rich or stalling
New hardware and tool will be provided to make this blow-off valve ready for the installation

It sounds amazing. Installed on my break, Took about 5 minutes. I love the sound and the throttle response feels alot more responsive. I love to use my launch controller pulling up to a mustang, evo, civic or wrx at a stop light or parking lot and just let off the throttle then u hear the " Psshh". I havent gotten a check engine light on.

Pretty solid BoV
BPVend 3 years ago
Got rid of a cheapo HKS and picked up this one. The sound while driving is pretty muted at anything other than near full VTA. 80/20 is barely audible when driving, and 50/50 sounds pretty darn nice. This is more of a deep whoosh sound compared to the HKS psssssss sound. The only thing I disliked about this was how the flute covers the bolt head. You have to dismantle the BoV a little to put the bolt in (see the right bolt eyelet in any of the pictures). I did not realize this until I already had the recirc and left bolt in... Just my luck!

Sounds awesome!
Bald Eagle 22 days ago
I really loved the idea of being able to adjust how much I could vent or recirculate and change how loud the blowoff would be. It was very easy to do and drastically changed the noise level as well. Cranked all the way open it was very loud and would get some crazy backfire going. I usually only had it about 30% open which was perfect. Everything was great with it until I took my car to get tuned at simple performance in Salt Lake and they smoke tested my car for boost/air leaks and the valve wasn’t sealed up completely. Apparently it’s a common issue they see on the GFB valves. You can risk it and might get a good one but I’d just go for something else. I currently have the turbosmart 50/50 valve and it works perfectly, it’s not as loud but is better built.

Good oem replacement
BooSTI 9 months ago
Been running this for about 3 months now and so far it's definitely perfect for a subaru replacement. Anything over halfway open venting to atmo starts making the car back fire on deceleraton since the maf is setup for recirc but the option to vent 0% to all the way open is very nice. No problems leaking with the provided gasket. Would recommend to anyone replacement an oem recirc valve. The sound isn't bad but it's not anything out of the ordinary so if you want that whistle your only going to get the air shooting sound out of this.

Did you have to tune your car once you installed it?

Will this fit a 2013 STI Hatch? I know it's not a direct fit but can you buy an adapter?

Sounds amazing!
Subie17 12 months ago
Installed this on my 2004 WRX wagon a couple months ago. Install was pretty easy, as long as you pull the intercooler away from the intake manifold a decent amount. I have it set to 100% atmospheric, and it sounds AMAZING. Not the best for my spark plugs, but hey, even with both catalytic converters it still pops here and there :) (Note, it does touch the intake manifold, but I haven't had any issues with it yet.)

Q: Gasket Chief 4 months ago
Answer
So I don’t think mine came with a gasket? Where is it located in the packaging? All it has is a small Oring where the valve connects to the intercooler.
- A: This will not come with a replacement gasket.
