Kraftwerks Supercharger Owners Thread

"would you buy this kit again?"

Absolutely. The only real hangup with this kit is the belt. It's fussy. I'd rather deal with one bolt and a fussy belt than some of the issues on other FI kits. Fussing with one bolt every once and a while is worth the ridiculous amount of speed this kit adds.

Yeah but they just did that huge group buy and no different than the BRZ/FR-S kit, packaging and making sure people get the right parts the first time is not their strong suit, so I could see them still focusing on the "somewhat new" or "newer than the original low side mount" S2k Kraftwerks kit.

Same here.


BTW: Anyone experience that the air in-tube becoming noisy like a high pitch whistle. I'm pretty sure it's the in-take tube, because it was able to trace it the when I cleaned my air filter. The pitch is coming from the in-take tube with or without the filter.

I helped a little bit on "testing" some pulley setups, running pulleys daily that they didnt put out for the regular customers, like the 19psi pulley i was running, In the beginning i went through 2 belts, the first i didnt have tight enough and it had belt slap on the lower mount, the second broke because of the smaller old pulley set up, we found out gates didnt recommend that small of a pulley, once we got the new pulleys, i went 12k with zero issues and over 450hp. i updated some pulleys, smooth to toothed pulleys and when we did the belt was over tightened and snapped. my friend did it while i was installing a kit. I knew it was to tight but it was late and i figured it loosen it the next day. it had a very loud whine, the next day didnt come and the belt snapped. he tighten it like a serpentine belt and made it way to tight. my laziness caused that breakage, if i would've loosened it it would still be here today

So ive been asked locally what i think of the kit. I tell them all i would buy it again. i have no regrets. For me the kit works, it was the power delivery i wanted, more power then i ever thought id get. And while i love sitting and playing around with some high powered Turbo cars around here. i know for sure no doubt id get this kit all over again. maybe not the 19psi pulley i had, but i dont have no issue with this kit. I am 1000% happy with my purchase. Ive been trying to get the owner to pick one up for the shop FRS.

I would buy this kit again, and again, and again.

As far as F/I is concerned this is my only experience on this car in particular. Having many other projects in the past I would say that this kit is one of the best I have had to install and the power delivery is exactly what I was looking for. My only gripe thus far would be the finicky belt tension issue, which I'm pleased to say I have finally found the "sweet spot" and thus far no issues.

Because i ordered a Mercedes Benz CLA250.. you know this why come on here and start trash, you follow me on Facebook.

The car is 100% stock, as of this past weekend.

I would assume a part out will net you more return on your money than selling a modified car as a whole. Never been through it myself

Correct. parting out my car gets me the 17-18k Mercedes is giving me, and then the 13k or so for all the parts. or i can trade it in and mercedes just gives me the 17-18k with all the parts and i lose all that money. Mercedes asked me to return it to as close to stock as possible. for me its easy as i kept ever part. even the scion badges when i replaced them with toyota badges

I would buy my kit again on the account that I've had 0 issues for over 10,000km on this kit. No broken belts, no warranty claims, nothing. I am happy with the power right now and can't wait to get a custom tune done after my Tomei EL header, over pipe and 80R exhaust get put on.

If I had a clean slate I might consider a turbo kit, but for superchargers I can't say anything bad about KW in my experience.

This is my first time doing an aftermarket FI modification, and the KW kit definitely hasn't done anything to turn me off from doing it again for future projects, if any. CARB approval doesn't apply to me, so this has been a plug and play project with no stress at all.

Seems to me that there are a few individuals here trolling and giving out some false information.

With that said... one of the most notable discussion topics is that of the C.A.R.B. approval on the kit. Simply put, it has taken far longer than we ever thought or hoped the process would take. It has been quite some time since we've attempted to have any product approved for California use and although we supply mainly to customers outside of the state, we have decided to invest the time and money into achieving the approval for this particular kit as well as others in the future. As of today, June 24th, 2015, the information from the testing has been submitted to C.A.R.B. and we are awaiting their approval. We anticipate having an EO number within 6-8 weeks. It is only then we can formally announce that we are approved publicly.

Communication and CARB aside, there is another topic that is surfacing lately being that Rotrex does not approve of a cogged pulley option. In response to that, we leave you all with these:

Jeff

you can run cog belt or chain as long as the very critical dimensions mentioned in our guidelines are kept.

Kind regards, Anders

Dear Mr. Giovino

Our superchargers do not necessarily have to be driven by a poly-V rib belt, but this is our standard as it accommodates most modern engines original belts. An advantage of the poly-V belt is that it can slip, compensating for engine rattle and rapid transients. All our internal tests are done with poly-V rib belts, but we do have costumers that uses cog drive belts with good results.

Best regards,

Søren Schmidt
Lead Engineer, Support & Quality Assurance

These are emails directly between ourselves and Rotrex prior to the design the FRS/BRZ kit and the re-design of the S2000 kit in which both representatives approve the use of the cogged pulley and even mention other companies were using cog with good results.

If there are other matters that need addressing or if you have existing, unresolved inquiries, please reach out to me directly so that I may assist you.
