Do you currently have a Kraftwerks Supercharger installed? I have a few questions
 

[I dont want to read through all of the posts on the owners thread. I have a few simple and to the point questions that could be answered with a yes or a no.


thats it. real simple. if anyone feels like answering then i thank you in advance.] :thanks:

EDIT: if you wouldnt mind, please list the Vendor you got it from ;)

1. Yes
2. Bought during groupbuy, so yes
3. Nope nothing has failed or caused issues.
4. Gas mileage went down as I developed a lead foot
5. Yes, I'm no longer the slowest sportscar out there. Plus the option to upgrade to the larger blower, should keep my horsepower hunger satisfied for a long time. If not, sell the car and try to find a good used evo X

Keith has this kit. Hit him up on FB

yeah he loves it. he let me drive his car and i thought it was awesome. but he just got it so im really trying to find out if anyone has any regrets since installing it

according to the owners thread, there are at least 34 owners of this kit. id like to hear from more than 1. i know people on here are helpful so ill check back later.

Post in the owners thread

KW doesnt make superchagers.

They utilize a Danish built compressor with their own adapter.

They also use a cog (toothed) belt which Rotrex does not recommend using.

There are not many track users that show up at the track, beat the crap out of their car, then drive home.

But, I hear its a half decent kit.

I drive hard at the track with my KW kit, in fact I have couple track days this weekend (Friday and Saturday) so far so good..KW kit is the only FI option I would consider for track use and the reason why I purchased my car ..;)

To the OP, see my build, I have purchsed my car in March and attended about 5 track days in the last couple months (first two events stock, and 3 with the KW kit) will be doing couple more track days this week and most likely attend another 7-8 track days this season, that's 15-16 events in one season.. Soo, I'm not sure how many people see that many track days in one season (especially with a FI car) but I didn't run into any issue so far, I well maintain my car and datalog as much as I can FYI

Thats good to hear.

Ive only seen JR kits at the track days ive been to

BTW, where did you hear that Rotrex doesn't recommend the cogged belts?

I heard a shit load of crap about it, to the point the owner threw it away and is going turbo

I've fixed that for you ;)

I heard it directly from Rotrex.

@D K what's your setup?

That doesn't make any sense at all :) I wonder if you spoke someone from customer service because some of the people are clueless about the details about their products.. "Cogged belts are not recommended because they may not slip/fail as much" joking aside I would like to hear the reasoning behind that

Im not sure.

I spoke to the janitor.

If that's the case, it should be correct because they know a lot better than customer reps..
I'm changing my belt tomorrow

No rumours or crap, and the kit had one of the best tunes out there. The owner is pretty active if he would like to chime in thats up to him.
I wouldnt go talking shit about something if it was only rumours.

Cogged belts have an issue when you snap off the throttle.
Theynalso cause vibration to the internal planetary mechanism because the outside of the cog is larger than the inside, so you dont get the smooth transition that you get with a serpentine belt.

Rotrex or not, there are a lot of people having issues in a roadrace type of a situation.

Makes you wonder why the person who brought Rotrex into the US left KW and is using a non cogged application for their kits.

Just sayin'

no issues here ;) I personally like KW kit better and I don't really care who brought what.. that doesn't prove anything in my opinion, that person could be anyone who have enough funds and connections..

One thing no ones asked.. To the OP do you plan on using your car in winter? Seeing how your location lists NY winters are real there. You should note KW does not make a thermostatically controlled engine oil cooler setup that works with their kit. Just something to consider in the whole process is all.

Didn't take long for the JR guys to show up

To add to that, the elusive non-thermostatic skunk2 oil cooler adapter plate is still not officially for sale yet as far as I know. It's the only adapter that works with the kit since the giant SC mounting bracket blocks all traditional style sandwich plates. Apparently KW do not have plans to make a full plug and play oil cooler kit with lines and core with mounting solution. Those who have asked have been told by KW to figure it out themselves.

Just to confirm my understanding.

I have to remove my mashimoto oil cooler if I want to use KW super charger?

That's correct. You would have to run without an oil cooler until KW release their proprietary adapter plate. Then you'd have to figure out the lines, core, and mounting solution yourself.

i was going to get the kit and use the mishimoto oil cooler. this all seems pretty random. ive seen and heard from so many KW SC owners and none of them have anything bad to say.

FYI call and order the oil cooler sandwich plate if you want it. It's that easy.

Where? I don't own one, not even FI yet. As far as I know ATL BRZ does not as well so .....Me.....Just a guy who will go FI in future and has read a lot, spoke to people here through messages, on phone, and seen kits in person, I like many like to make educated decisions.

I like a lot about KW kit however living in a cold climate, a non thermostatic option is a sale killer for that reason. Over cooled oil is as bad or worse then too hot, and well that's fact is all.

so what does this mean? youve ruled out the KW kit? are you leaning towards a different one? please share

:laughabove: :laughabove: :laughabove:

If KW does not produce their own TC oil kit by time I'm ready then at that time yes I would rule that out as honestly I feel that is important based on my climate being cooler then many, even in summer mornings and evenings. Supporting mods to FI are essential to long term success. Other SCs I'm considering are the JR kit (since it has all supporting mods including TC oil kit and hasn't had any issues, as well as new HKS V2 kit looks very promising as well. For turbo the options like Ptuning also look great due to low placement and proven track worthy. My future plans for my car are to be a play/track type car only.

I have nothing to gain by saying negatives or such just sharing what I know there are several folks in groups here now FI with their cars and there are so many options now it's over whelming really. However I was only trying to share that one aspect (TC oil cooler) which may or may not matter to you and your needs. Otherwise sure KW looks wise looks good, but function is IMO more important and the idea of a second belt also gets promoted a lot however still to this date haven't read or seen a single owner of the single serpentine belt systems have failure either so....

Good luck with whatever you do, whichever way you go you'll be happy cause you are taking your time and asking questions which is awesome, so many just buy whatever with no clue then are filled with regret.

Is it just me or do you like the higher priced options? :thumbsup:

Haha, yep
:lol:

Check with @Digitalassassin

he has been running the kit a long time and would be a good resource. He is in the Pacific Northwest

good luck

like which one? AFAIK, the OEM Forester XT /WRC oil cooler is the biggest sized sandwich plate and I had no problem installing with KW kit ;)

and one correction, KW recently released their oil cooler kit which costs less than other other oil cooler options .. I personally haven't tried that one yet and yes it doesn't come with a thermostat @Digital assassin added his own Derale remote thermostat, it costs whopping $60 on Amazon :lol:

Bob from @Drift-Office recently posted a SC shootout which you may find interesting
For the record, he is a very reputable tuner and I agree with his opinions ;)

Perhaps but honestly I've learned long ago spend smart & spend once is all. :)
I've spent countless hours speaking to people about various kits, vendors and manufacturers, examined peoples kits in person and had great learning discussions. To me it's about making the absolute best decision and being well educated on it.

There are a few that do not seem to present any issues given you as an owner examine your kit and know it inside and out. The one fact that remains solid in my mind is that the proper supporting mods day 1 ie: TC Oil Cooler, Catch Cans, Radiator (if needed) quality DD drive able clutch (if not track) etc etc all are as well just as important to the experience so at that point cost becomes a tad moot as ones jumping into the big fun pond?.... :D

Yes he did and it looks like a great option. Point being it shouldn't be up to a customer to get told to figure it out themselves when some other manufacturers do it for you as a package proven deal? When I saw Digitals solution...I actually thought KW may jump on DAs idea and scoop a whack of those up and provide them....be a smart move IMO.

I agree, but adding a thermostat is not really big of a deal, I personally like the water to oil types like OEM options instead of stacked plate/ external air to oil type oil coolers but it seems like the OEM oil cooler (even with adding a bigger radiator ) is not enough for hard track use (I 've just learned that I made a mistake) :) I will soon upgrade to a stacked plate type cooler even I am not a big fan of them ( possibility of failure, lower oil pressure ..etc)
