Why is the HKS SQV4 Universal Super Sequential Blow Off Valve So Damn Good?

Today we are covering everything you need to know about HKS’s line of different Blow Off Valves, and kits, and which one is the right choice for you! We will cover the most frequently asked questions along with some hacks to making your blow-off valve louder. We are going to turn this post into the ultimate buyer’s guide for HKS Blow-Off Valves by explaining in detail why HKS SQV4 Universal Super Sequential Blow-Off Valve is so damn good. For those who don’t know, the HKS Sequential BOV is a well-known and highly regarded blow-off valve (BOV) in the automotive aftermarket industry.

The HKS Blow-Off Valve is manufactured by HKS, a prominent performance parts manufacturer based in Fujinomiya, Japan. The company introduced the SSQV BOV in the early 1990s, and it quickly gained popularity among car enthusiasts around the world. HKS is respected in the aftermarket industry, as the company focuses on designing products that solve problems found in stock parts. This statement is especially true when it comes to the design of HKS BOV SSQV, which was designed to address the limitations of stock blow-off valves, which release excess pressure from the turbocharger system when the throttle is closed. Due to their poor construction from inexpensive materials which are not optimized for performance and limiting design qualities, stock BOVs often suffer from issues such as leaking, slow response times, and inadequate flow capacity.

With the manufacturing of HKS BOV, the brand sought to overcome these limitations by developing a blow-off valve that offered improved performance, reliability, and sound. The SSQV was designed with a unique sequential valve structure, which allowed for quick and precise pressure release. It utilized a piston-type design with dual valve springs and diaphragms, providing enhanced response and durability compared to stock blow-off valves.

One of the critical reasons for the popularity of the HKS SSQV BOV is its distinctive sound. The sequential valve structure, along with the dual valve springs and diaphragms, creates a distinct and recognizable “whoosh” or whistle sound when the pressure is released. This sound has become synonymous with turbocharged performance cars and is often desired by car enthusiasts as a flex of power and performance when done tastefully.

Additionally, the HKS SSQV BOV gained popularity due to its reputation for quality and reliability which are signature characteristics of HKS products. The company has a long-standing history in the automotive aftermarket industry and is known for producing high-quality performance parts. The SSQV BOV was designed and manufactured to meet HKS’s rigorous standards, ensuring long-lasting performance and compatibility with a wide range of turbocharged vehicles. Typically compared to its knock-off versions, the authentic HKS SSQV is constructed and engineered to meet the demands of high-performance vehicles, and their quality and long-lasting characteristics make them worth the bucks. We do not recommend the knock-off version blow-off valve as a replacement.

Overall, the HKS SSQV Blow-Off Valve has achieved popularity and acclaim among car enthusiasts due to its superior performance, distinctive sound, and reputation for quality and reliability. It has become an iconic aftermarket upgrade for turbocharged vehicles, offering improved functionality and an enhanced driving experience, and sound.

Since we promised you answers to your HKS SSQV questions, here are some of the frequently asked questions when it comes to this BOV;

Can the HKS BOV be adjusted?

Answer: No, the HKS SSQV is not an adjustable BOV. Although, for higher power and larger displacement applications, HKS does recommend the Racing SQV. The Racing option (71008-AK004) is a larger 51MM valve that has an adjustable pre-load for a wider range of high-performance applications.

How to make the HKS BOV louder?

Answer: The Blow Off Valve can be made louder by replacing the original Fin. HKS produces 2 optional Fins for the BOV. The Gold Triple Fin (1422-SA002) has a mild blow-off sound that is a bit louder than stock. There is also a Purple Round Fin (1422-SA001) that produces a louder and higher frequency blow-off valve sound. (Pshhhhh) We’ve found the Purple Fin seems to be the people’s champ.

Is the HKS BOV easy to install?

Answer: Yes, the installation process for an HKS Blow Off Valve is rather simple. Although, if you decide to go the route of buying a Universal Blow Off Valve kit, it can take some extra fabrication and piping to fit the BOV to your vehicle. This would make the installation more advanced and require more technical knowledge.

How do you install the HKS SSQV?

Answer: Installing the HKS Blow Off Valve is a rather easy process and all the installations manuals can be found here: https://www.hksusa.com/manuals#blowoff

2JZGTE poor throttle response. via /r/cars

2JZGTE poor throttle response.

I own a 2000 Toyota Aristo with the 2JZGTE vvti motor. After driving another Aristo with nearly the same mods iv noticed its much more responsive than mine. I experience significant lag in the throttle response when pressing the gas pedal.

I have a full 3inch exhaust, cold air intake, boost controller - set at 16, and an HKS ssqv BOV. The other Aristo has a stock BOV, that is the only difference.

Now i have noticed that my car feels noticeably unresponsive in the low rpms compared to the other. It feels as though i need to press on the gas pedal about 15-20% before any boost starts to build and the car gets going. While comparatively 5% throttle on the other Aristo and the car just gets up and goes. These numbers probably arent accuarate but give you an idea of what im trying to get at. Also worth noting, if i try to get my car to backfire, revving high then tapping the pedal to manipulate it - on occasion the car will stall when i come to a stop next. Not sure if related. Also feels like it takes longer for the 2nd turbo to come online. Also comparatively getting pretty poor fuel economy (maybe 350km for a full tank in the city if im lucky). Only occasional blue smoke on a cold start (likely valve stem seals) and absolutely no abnormal noises from the turbos.

Iv done a boost leak test, it was a while ago and its worth trying again. Iv changed the vacuum hoses to the VSV, havent actually tested the VSV. Cleaned the MAF, although it is only 3 yrs old. New VVTI solenoid. Boost gauge indicates -17/-19 inhg (appropriate levels for where I live). Im making 8psi on the primary turbo, 16psi with both online. New spark plugs installed (NGK bkr7) gapped to .028.

When I first bought the car my TPS failed and my mechanic replaced it with a used one from a parts car. Im wondring if perhaps the TPS could be an issue? Iv also considered the EBV/wastegate actuator for the primary turbo could be fatigued.. Its located next to the exhaust manifold so perhaps heat has worn it down?

In the higher RPMS I pick up power just the same as the other Aristo.

Just curious what other factors could be affecting the acceleration down low. Im aware of turbo lag but like i said the other Aristo is quick and responsive so evidently something is off. Im just hoping it isnt the actual bearings in the turbo fatiguing.

Thank you in advance for any insight.

FMIC on relatively stock 2jzgte worth it? via /r/cars

FMIC on relatively stock 2jzgte worth it?

Just looking for a bit of advice. I recently acquired a front mount intercooler core, with a 2.5in inlet/outlet. No piping yet and I received the core pretty much free from a friend (unused)

I currently own a 2000 Toyota Aristo with the 2jzgte vvti motor.

The car has a full 3in turbo back exhaust set up, cold air intake and a hks ssqv bov. That's pretty much it for mods, otherwise the car is stock (stock ceramic twins).

I do plan on getting a dual stage manual boost controller or one with a scrambler mode and likely a fuel cut defender but for the time being I'm wondering if its even worth it to have the fmic installed. Iv heard the the throttle response can be affected along with pressure drops.

So my question, is it worth it to install a fmic with my current set up? Would I need a boost controller to up the boost to even notice any difference with a fmic?

I'm not looking for huge gains from the fmic, I understand it may only aid in recovering lost HP from heat soak, but with stock twins I'm doubting whether it's worth the headache of getting it on.

Thanks in advance

Any veloster turbo owners who installed a bov? via /r/cars

Any veloster turbo owners who installed a bov?

This is a long shot and hopefully I can post this here but are there any turbo veloster owners who have a bov installed? I'm looking into getting one and most of them, the ssqv, have to have a hole cut in the bumper to make them fit. I'd like a bov that fits to where I won't have to cut anything, so do any of you know of any bov that don't require you to cut anything?
