HKS Supercharger owners thread
 

Would be interesting to see who else is using the HKS unit and their setup.
I am just waiting for an ECUtek dyno tune appt in 2 weeks. In the meantime waiting it out on the F-Con iS conservative tune. Goal, about 245 at the wheels, 300 at the flywheel.
The rest of my setup in on my signature.

I am hks v2 supercharged

^^ Yes, I followed your threads regarding the S/C. Very nice build, all performance. Had I been involved in tracking my car prior to purchasing the 86 I probably would have gone a similar route. Rather, my focus was more on the esthetics and sound at the beginning. I hear Scotland has a very similar climate to Canada, in the more densely populated areas.

Tried Tennent's beer last night. :cheers: It might just be the nicest, mildest beer I ever remember drinking.

283 at the hubs here. HKS V2

What supporting mods to achieve that power?

HKS manifold, HKS front pipe, tomei overpipe, M7 Exhaust, ARC intake Restricter bored out to larger size on V2 kit.

Nice engine bay. Love the red paint, my WRX is the same colour. Was going to leave in the stock front pipe w/resonator and cat. I wonder if it will make much difference in the power I will get after the tune? I have a feeling it wont change much.

Mine was mapped on a dyno with Ecutek

Wondering if the skunk 2 airbox would fit this setup.

I'm wondering how reliable this SC is on the track. I was leaning towards JRSC since many owners of that kit seem to have no issues on track days regarding reliability and overheating. However, since Yen is down and I have to purchase from overseas regardless of my choice on a SC kit (which means additional shipping costs for everything I buy :( ), HKS V2 SC seems very attractive not only because it's cheaper than most other kits but also HKS is known for their top notch quality.

So if any owners of HKS V2 SC track your cars, please enlighten me on how it performs!

Also, I am aware that this kit uses restriction plate. My goal is to be at around 260~270whp with header + OP + FP + catback. Will the restriction plate be modified or can I make somewhere close to my power goals with unmodified restriction plate?

Thanks in advance! :D

There's a 38mm plate and a 42mm plate. If you are going to tune your vehicle, you can bore out the 38mm one to 42. I probably wouldn't remove the plate completely, from what I understand the plate is there so you dont completely lose all your low end torque. I have the 42MM plate and pretty much everything you described with a V1 setup with the V2 intercooler upgrade. The only thing I dont have is the front pipe (using stock w/ resonator & cat). I am expecting somewhere around 245 WHP after tune. That translates to around 300 at the crank.

Ver2 here with 43mm restrictor
248whp 209 max tq at the wheels
REALLY need to kill the stock header / overpipe I think. I have a big dip in power

The standard restrictor is 39mm, the 'upgrade' is 43mm.
The plate (restrictor) is only there to limit the boost at high rpm, it basically only allows in so much air before it chokes and then the airflow remains around the same as rpm rises (therefor boost is capped / starts dropping with rpm)

Removing the restrictor completely will not lose you any low end, it will only add power towards the top as you are no longer limiting airflow there. Can a stock engine handle an unrestricted supercharger? I don't know, it definitely requires fuel upgrades though.

Oops I was out a mm :) I had read the low end torque thing somewhere but it doesn't really make sense does it? I am afraid I have given wrong info that I had assumed was from a credible source. I have 700c injectors and a smaller pulley but will hold off installing them for now. I will seek advice on whether to keep the restrictor in when I see my tuner on the 18th of this month. The goal for now is 300 at the crank. I am told all I need is a bigger fuel pump and to install the upgrades I have sitting in boxes for 350 at the crank, roughly 300 at the wheels. My concern is that will lead to other issues such as the clutch and longevity, and frankly the car should be plenty powerful for my use already.

at 3800$ this charger is really a great option.

what is the diffrence between the ver 1 and ver 2, other than the obvious intercooler and piping?

V2 utilizes the stock airbox as well.

thanks, so it looks like the actual supercharger itself is the same unit. i hadve a really good deal going on for the version 1.just wanted to ask.

V2 with 43mm restrictor which comes with the HKS injectors. Delicious Flash & Go tune. Did not measure on a dyno yet.

Car is now grounded due to unknown issue which seems like the DI seals failure but after replacing those and checking various other possible reasons the problem remains... Tried everything. No idea what to do next. Probably will buy the HKS stroker kit and get the engine re-built :)

I'm really liking the v2 supercharger from hks. The v2 shipped from japanparts to my location is $3500, very tempting.

Couple questions though:
1). How much plug in play is the v2 kit? Any cutting, modifying needed?
2). What oil cooler are you guys running? Is it required to use a specific hks oil cooler or can I use a different aftermarket oil cooler? Will I need an oil cooler for a daily street setup?
3). Will a uel header be compatible?
4). Does it work with a 6AT?

I'm ways away from getting this but I'm definitely looking to go FI in the future. I'm thinking either this or JRSC.

Dyno tuned today with ECUtek for 94 octane with restrictor delete on Dynapack. Result 275 WHP, 210 ft/lbs torque. Speed density tables were applied. Tuner said he typically sees up to 50 HP powertrain loss on these cars so I'm somewhere between 315 to 325 BHP for people who don't know cars haha.
I have the smaller pulley and 700c injectors never installed if anybody wants them to go Stg 3. I am Stg 2 with upgraded intercooler BTW.

Hey hey HKS V2 friends ;) nice to see this setup is popular on the other side of the Ocean as well !

My BRZ is also "HKSed".
Previous user of the V1 kit , this time we upgraded to V2 ...fully unrestricted, the supercharger blows in a fully rebuild engine with HKS 2.1 stroker, HKS Vcams, HKS injectors, HKS manifold , no cats, Tomei over Pipe, Blitz straight pipe and finaly HKS highpower Spec-L firing trough pretty much every gears.

The results are ... interesting ;) on the same type of dyno (dynapack) as wbradley it scored 366 whp, and 295 ft/lb of torque, there is still meat on the bone, but for the sake of not killing the transmission too fast we decided it was good enough ... best run was 380whp, that sets for way over 400 crank hp

here is the dyno for the records, as you see the dynapack isn't a very forgiving device given the 145hp stock at the wheels, but that's just the norm on it .. So its more than x2.5 stock power.

Can't be happier with the setup ! feel free to ask for anything you would like to know.

1 fairly plug & play , yet better let it done by a pro if you aren't one! cutting will be needed for the HKS Engine oil cooler if you want one, as it sits in the wheel well. Other options are possible, but this one is the best as everyhting has been routed with HKS v2 piping in mind.

2 well, see 1 ;)

3 yes, but EL is the best option, UEL will drastically lower the performance, on a V2 setup, UEL headers typicaly score 20-25hp less, that is what SCREEN's boss usually see on the dyno.

4 yes totally works on AT, yet the results won't be as high, more losses in the transmission :)

Porsche killer!
And on a lighter note, as a Frenchman in Japan (single?), you should do pretty well with the ladies. I understand from a long time dating back before WW2 the more worldly Japanese had big appreciation for French culture. The champion Japanese Iron Chef on TV is a French Chef.
My teenage daughter and many of her friends are into the somewhat innocent Lolita scene from Japan. People photograph us when we go out all the time and the pictures get thousands of hits on Instagram. Not all Japanese girl stuff is so innocent though :)

Funny you say that, because yes, it is indeed a Porsche killer, on my local mountain road a Cayman S doesn't stand a chance, specialy on the way down where i can just rely on my lighter car and the monstrous brakes. It actually became a "many things" killer indeed, should I be brave enough coz, let me tell you passed 5.000 it really wakes up and offers you a pretty juicy shoot of adrenaline in the pants.

As for "japan", well I got married two weeks ago, but yes indeed, i'm an "exotic" here, so attract a lot of ... attention ;)

I hope to see more of the HKS chargers around, will report that to my friends at HKS Dev they'll be super happy !

Here is where your stuff comes from, crafted at the feet of the Fuji !!

Congrats on the marriage. Saw a nice writeup this week on the HKS complex on NASIOC. Cool.

Thank You. Btw i absolutely love your car. I'm also wrb :cheers:

What else exactly needs modification/cutting to fit?

Wow thats a hell of a drop when using a uel header :cry: hard to believe as other rotrex superchargers dont suffer the same when running uel headers. I'll take your word for it though :thumbsup:

From what I understand is that hks has a specific oil cooler for the v2 supercharger. I'm honestly not sure I need one as this will probably just be a daily driver with a few pulls every now and then. No track days for me.

Is this whats recommended?

Im not looking for much but i'd like to make 300 at the crank using 91 shell v power tuned with ecutek(no 93 or e85 here). Mods would be el header and a catback exhaust(maybe a front pipe and overpipe if i need it to achieve those numbers)

You ABSOLUTELY NEED AN OIL COOLER !! don't even make the mistake not to fit one. It is absolutely critical, this and to be able to monitor oil temp, and pressure ! Daily driving your car can be a real issue as well, sitting in the traffic could be bad, with a V2 blowing in its lungs, trust me, temps can go sky high if you don't have an oil cooler. If you are ready to invest thousands of $ for the V2 kit, don't go cheap fit a proper oil cooler, and yes the S type is the one to use.

Your setup seems good for the power you want, yet if you live in a hot area it might be a litle more complicated but still :) that's the way to go.

V2 supercharger, EL no cat header, over pipe, front pipe, exhaust , Oil cooler, break pads, tires, and possibly clutch ...

On the EL / UEL debate, i'm going to talk on what i know, HKS has also an UEL header, they don't recommend it at all for any perf oriented setup ... some will argue it is horse s** but fact is i've seen two 86 on the dyno, one with a UEL hks header, other with EL one, the UEL was down by 20hp ... would it be the same with other UEL setup, I don't know but you got my note on it :) UEL isn't a "performance" setup anyway ... subaru doesn't use it anymore for a reason, so isn't Porsche ... Yes it sounds cool, but comes at a price.

I will take your advice and go with an EL header instead as well as a oil cooler since we usually average about 81 degrees Fahrenheit annually.

Hmmm so I followed the hks link from, https://www.japanparts.com/parts/detail/43635 and it lists the oil cooler as discontinued?

I did a little more research on hks website and I also found this oil cooler which seems to be a updated unit.

http://www.hks-power.co.jp/en/produc...oling/db/15613

Under remarks it lists that the 6AT as "not tested" I'm guessing they meant that literally and not fitment wise? Which would be the better/recommended of the two?

To avoid any confusion, the supercharger kit comes with it's own small oil cooler for the traction fluid. My kit purchased used, didn't have it and I had to track down a very small radiator to subsistute for it. HKS America indicated the car is safe to drive without it but no long trips or track days.

I also bough a 19 row oil cooler/sandwich plate as oil temps will rise dramatically after spirited driving.

You're running the v2 setup right? What brand oil cooler did you go with?

I noticed you also have a 15 wrx, I'd love to hear your opinion on how your current car is now compared with your 15 wrx if you don't mind.

I have a V1 kit with the V2 piping and intercooler. So, basically I have the same as a V2 except with the HKS mushroom intake.
I got my oil cooler from CX racing for $369. US$ (quite a bit more once landed here in Canada after shipping, duties, taxes, conversion). A few parts were short shipped but when I do install it I will write a brief review. I also bough a small 7 row oil cooler to substitute for the missing one for the supercharger.

The '15 WRX is a totally different animal. It's the family/commuter car with a sporty twist. Just installed an HT style front lip. If I didnt have the FR-S I am sure I'd have gone for the STI. The WRX gets MUCH better mileage that an STI and still handles great.

IMPORTANT QUESTION: LHD HKS owner
 

ANyone that has a LHD car,

The install manual I am referencing is the online PDF for the V2 but I have a V1. It is the same either way.
When facing the car looking under the hood, which side of the supercharger is the traction fluid inlet and which side is the outlet?

The manual is horrible for illustrating this and some photos are RHD and it is unclear.

I recently added in a traction oil cooler and filter which were missing from the unit I bought used. The oil appeared to be moving in the reservoir normally. Took the car out for a test run and after a few minutes there was a high pitched sound and the supercharger seized, stopping the engine.

I have removed the belt from the pulley and I cannot rotate the pulley manually at all in the proper direction or otherwise. The car cannot be started as there is so much resistance on the belt it cranks literally inches.

I probably killed the supercharger and need to confirm I had the inlet/outlet reversed.

Once confirmed, next step will be to try and find someone who can open the supercharger once removed and if repairable, rebuild it. Otherwise I will need a new blower and who knows what that will cost me.

Any idea if this is rebuidable if not mortally damaged helpful as well.

I was wondering what this kit sounds like, is there a supercharger whine to it while driving?

Is this kit CARB legal?

Thanks :D

wbradley: sorry to hear! with the s/c mounted, the oil pump inlet is on the lower right-hand side of the drive. The oil pump outlet is on the lower left-hand side. The picture in the manual isn't the greatest, I'll agree, but the plumbing layout is accurate.

HKS does offer some service parts:
http://www.hks-power.co.jp/en/produc...ch/product/727

But from your description, unfortunately you'll probably require a new s/c.

Kckc1: the s/c doesn't have a traditional whine like a roots type blower, mostly due to HKS' unique traction-drive system. We've run ours with a Racing Suction filter and through the stock air box and with the RS filter, you could hear a little "swissssh" from the intake air, but no whine. Through the stock air box you can hardly tell it's there.

surfuxalot: No. Not yet anyway.

Hi Scott,

just curious as to what's the difference between the 2 types of traction oil?
12002-AK029
12002-AK030

and which one is included in the V2 kit?

Cheers,

AK029 is included with the kit and should be fine for 97.2% of the users in the USA.

AK030 is for cold weather use only [-20C / -4F].

Interesting that the traction fluid filter is on backorder even though despite the relatively low replacement frequency, it is a consumable item for this kit. Also, the oil cooler cannot be sold separately. Virtually all Rotrex type and Vortech centrifugal superchargers are rebuildable. And HKS offers a rebuild kit for this blower on the Japanese website yet the distributer in North America will/can not tell me on the phone if I can order those parts. I have a rebuilder and I have sent out the blower to be opened and hopefully repaired. Considering the blower alone will run me approx $3500 landed I would feel very disgruntled if the unit is repairable and HKS refuses to make the parts available. Seriously, that would be horrible PR. I see people rebuilding the other brands regularly as they can wear or deteriorate in performance on occasion. Why would there be a part# for a rebuild kit on the corporate website shown if they cant/won't provide it? Isn't rebuildability part of the decision making process when choosing which unit in the market to buy? This vehicle is a lot of peoples daily driver, so they need to have some product support for a vital component once installed. It's not like its easy to just remove it and move on.

Hello, I'm just curious if anyone has dropped a HKS Supercharger into an automatic?
