HKS SUPERCHARGER KIT PIX
 

Here are a few pics of the new Supercharger kit from HKS. These pics are courtesy of a friend of mine who was at the show. Now before you Supercharger hungry people ask me any questions I will let you know right now: I have only a limited amount of information so here are some of the questions I can't answer (meaning, don't bother asking):

Do not ask:

HP Figures
TQ Figures
0-60
1/4 Mile
Price$$$

The only thing I know is that this kit will not be available for a while. They are still fine tuning the kit and yes it will come equipped with the FCON. This is the only kit in existance as of right now. As far as availability goes, maybe sometime around Aug- Sept '05.

Here is more additional information about the kit:

The HKS Rotrex Supercharger Kits are the latest in forced induction systems for the aftermarket. The centrifugal type supercharger features a unique traction drive, with a closed oil circulation system. The traction drive utilizes fixed ratio planetary rollers that are more efficient then traditional gear-wheels. Because the planetary rollers do not have teeth like traditional gear-wheels noise is decreased and reliability is increased. The closed oil circulation system cycles a specially-formulated Traction Oil that lubricates and cools the supercharger, dramatically increasing longevity and reliability. The Traction Oil is cooled through a liquid to air oil cooler included with each kit.

All HKS Rotrex Supercharger Kits are developed as complete bolt-on systems. For certain applications HKS will include a front-mount air-to-air intercooler, Super Mega Flow intake, Bypass Valve, additional injectors, upgraded fuel pump and S/C Fuel Computer. Also included with each kit is a high-performance cast aluminum bracket which has been precisely engineered to reduce noise and vibration.

Enjoy the pics!

:D :D :D :D :D :D :D :D

me wants really really badly

wow
that looks awesome

ditto, kinda look like their kit for the 350z. Why does hks favor centrifugal sc so much? Might as well went for a turbo application. Looks nice either way, doubt it would cure the low end woos, but its FI nonetheless.

Well the reason why they decided on a supercharger than a turbocharger is because Superchargers will come on sooner. They are also much easier to be carb certified...especially in the US where CARB is an issue. And this was one of their main goals.

Here are a few more pix...

good point, since when did carb certification stop many of the consumers from getting FI? Especially when there is such a demand for FI for the rx8? Regarding a centrifugal charger coming on quicker is not neccessarily true, a low boost turbo kit like greddy has minimal lag. But i'll shut my mouth early, i'm sure HKS knows what they're doing, just wish they would have stuck there guns with turbo.

you have a point there, but that was one of their goals they were working on... Just wait a few months until more information is released.

FE3P is getting this kit installed on his car huh? :P

XDEED.. don't you work at HKS? Why don't you hook all the HKS stuff onto your car too?

:eek: Suddenly Greddy may have to wait........

WOW, thanks for sharing!

Just one question...how does the SC help transformablity? LOL

I think for me it's going to come down to whether SC or TC is more reliable...

:eek: yum....

wow... that looks so complicating yet so beautiful... i wonder wat kind of numbers that turn out to have

Is that a new Intake manifold? Not the black plastic??????

Looks like it.

HKS???? or another manufacturer??????????? Where do I get it????? :D

Hmm.. polished aluminum intake manifold... ahhh..... Wonder if they'll sell the manifold seperate.. if so I'll have to pick one up.


**EDIT** HKS sells the 350z kit for $7250, so I would expect the RX-8 kit to be about the same... :eek: :eek: :eek: **EDIT**

well, if you guys are looking for reliability, then u could say goodbye to that, Either a SC or TC would do dramatic damage to your 13B engine, it's just something you will have to sacrifice for FI. your Warrenty is another thing to think about. But none the less any FI so far out for the rx8 is very interesting, looking forward to those figures.

So, what you are saying is that FI messes up engines. How does it do that? What causes it to age faster or be unreliable. Someone already said this but I too would (If I use FI) go with whoever is more reliable and messes up the engine the least amount.

What is the lifespan of a Turbo or SC engine? If the engine will still (with proper care) still last me over 130,000 miles, heck maybe even less, then that would be OK.

The more I learn the more I worry about Turbo's and SC's in regards to reliablity and lifespan of my engine. Sure I'll have a much more powerful RX8 for 50,000 miles (if that number is accurate which I have no clue if it is) but is it worth the $3-5,000 if it's just going to last such a short time and will mess up my engine?

Based on what I see over time, I might just go with other mods to make the 8 better and stay away from the FI stuff. I worry that's all...

Many owners have gotten 100K+ mileage on their FC and FD turbos. My FC Turbo's original engine went more than 125K before it needed to be replaced. I see little reason to assume at this point that a properly tuned, conservatively powered Renesis (280-300 flywheel hp) wouldn't last just as long.

edit: Thanks for the information. I think I would side with Twin-Screw vs. Centrifugal, but anything that can get CARB certification has a significant leg on the competition as far as I'm concerned.

Well as far as the kit reaching American shores it will be a while... And no I don't work at HKS, I'm just your average HKS Junkie!! Ha ha... And why don't I hook my car up?? Well i'll be the proud owner of some HIPERMAXX II 's by the end of the month, and plus I have too many dam hobbies I waste my money on. BTW Did I mention I have an expensive girlfriend!..haha

Ya the g/f factor is a major expense indeed... spent about 4g's in Maui for a week this past week.

My plan of not modifying my car UNTIL the warranty expires is still my goal. I don't want them to have any excuses for my warranty to expire.. which is another 20k miles to go. Then I'll think about spending about 15k on the car, or just buy a new car.

Luckily I already paid off the car so that isn't an issue... but SC is the way to go I believe. At least Mazda USA is working on the SC Mazda RX-8, not a TC version.

While I do not particulary like the method HKS is using, I do agree that any forced induction which obtains CARB certification will have a leg up on the others out here and with me.

The greddy kit is not carb approved...

ouch that's a lot of american green backs for a supercharger kit..granted it is HKS (hence paying for the name and reliability)..but damn....then you have to pay to install it...what is the greddy kit like 3g's? hmmm i do like how it looks and sc may be the way to go.....but i can get the greddy and rebuild my engine in 100k miles when it goes for that price...ahhhhh hopefully it will be less (everyone cross your fingures)

thanks Mom

:p Mom's are always so supportive!

uhmm. all i can say is wow. im speechless. i wanna just go and jack it. 4get buying it. im gonna plan a secret way to jack this. this is my mission. MUhahahaha haha

You know it's not good sign when future pastor's go around jacking superchargers for their RX8s. lol

everyone please keep your first born away from him!

Why not get the HKS exhaust before the Hipermax coils XDeed? I would usually get the springs/coils after I get new rims to see just how much I would like it to drop.

That Loooks really good. I love the new intake Manifold.

i know i pondered the same thing...But i'm getting a real good deal on the coilovers. It was an offer I couldn't refuse! But after i get the suspension installed rims would come next...Then eventually the exhaust... =)

Autodelta is also using the Rotrex Centrifugal Supercharger on the Alfa 156 GTA and on the Alfa GT .

The question is whats the best type of Supercharger for the rotary engines characteristics.

A TWIN SCREW TYPE SUPERCHARGER OR THE ROTREX CENTRIFUGAL SUPERCHARGER ???

cheers

Uh, no and no.http://www.mazdamaniac.com/images/smiles/icon_no2.gif
Not only will a centrifugal not come on sooner, it can only produce boost at low RPMs as a function of the maximum boost at top RPM.
I've done both and they are quite different.

Plus, CARB certification doesn't care how the air gets in there, only how cleanly it comes out.http://www.mazdamaniac.com/images/smiles/icon_shrug.gif

Its aluminum so that the extra injectors can be mounted more easily.

Okay mazdamaniac...since you are a genius and know everything, maybe you would like to write to hks directly...like i said i have very little information about the new product. I was just informed briefly about this so keep your immature emoticons to yourself...

Immature? He is correct. This supercharger is going to pretty much suck on a rotary. It makes a lot more sense on the Z.

Whether I'm a genius or not has nothing to do with whether I'm right or wrong.
If you don't agree with what I stated, then refute it.

I surely don't know evertything. If I did, I would have known not to bother responding to your thread - knowing that you are such a blowhard.

I can't see myself spending 7k if the sc unit came out to be that much

I don't even wanna know the price..The exhaust is like $899 and thier intake is like $599..HKS is hella expensive..

I am simply here to report on the product not to debate or argue with you. I am not going to waste my time with you any longer..

As far as the Greddy kit goes the retail price is about $4200. Anything cheaper than that would be a street price...Now this is just an example: If the HKS kit had an MSRP of $7250, the street price would be under $6K. Now this is just a rough guesstimate...

Then why did you start and argument that you won't finish?

you pay for what you get..and you get quality...

Suck on the rotary? Thats an early judgement don't you think. There was a lot of R&D spent on this kit and HKS is not going to put out crap.

well, what xdeedubbx said wasn't entirely untrue, twin screw's have flat boost curves, and come on sooner than a turbo (jeff step in if necessary, it's been a long day). however a centrifugal is just the compressor side of a turbo spun by a belt connected to the e-shaft. unfortunately a centrifugal SC lacks any means by which to "bleed" the force of the belt turning it (whereas a turbo opens the wastegate once desired boost is reached), so it can only make target boost at max rpm. if it reached 5psi at 4500 rpm, then it would be 10psi at 9000 (the boost curve may not be linear, but you get the idea). you cant just bleed off the excess boost, since you'd loose alot of metered air and it would be a tuning nightmare, as well as terribly ineffecient.

HKS is a great company, and i'd pay $7500 or whatever if it was a turbo kit. i also don't like the fact that SC's pull the bearings to one side and rob power to make power. SC's are one thing, but a centrifugal is probably the worst option for this engine. it would probably turn a decent 1/4 time since there's no boost down low to make launching any more of an issue and plenty of power up top, but on a road course or daily driving it'd be a chore. of course only numbers and facts will tell. perhaps HKS has something up its sleeve...it is a gorgeous piece of hardware!

thanks for the heads up though man, i always love to see new things!

I don't think anyone is saying the kit is crap.
In fact, it will probably produce the highest peak HP of any of the FI kits that will be available in 2005.
It will also likely be the most blingy kit you can buy and I mean that in a good way.
However, the area under the power curve will be significantly less than a properly sized turbo or even a positive displacement supercharger running less boost. That is just the nature of centrifugal SCs.

I'm also awaiting Rotarygod's response into this thread... then my head really starts spinning with all the facts and details.

As far as I know, "MOST" RX-8 owners will use their cars as daily drivers... owning a SC or Turbo Kit for the RX-8 for daily driving is a joke. :P Unless you have money to toss Or/and plan to go track racing or something, there's really no reason for it. Save your money, go buy a faster car if that's what you are looking for.

My friend's 1998 Civic would still kill my car because all he wanted to do was increase the speed... make it super ricey. In the end, which car do you think most people are impressed with on the road? The RX-8, styling and profiling... or the Civic which has no back seat, rollbars, and driving on the 405 Freeway traffic going 10mph.

Hey now.. My RX-8 is a daily driver. Having the turbo in it I don't see any sacrifice in daily drivability at all. WHen the turbo kits in, you feel it in the kidneys, but you learn to drive around that as long as you massage the throttle and keep it under vaccume.
