Kraftwerks Supercharger Owners Thread

[NCItaly]

So, cvjoint returned his kit? No longer has one? So... is no longer an owner... so... wrong thread?

Also wrong forum. Looks like he drives an S2000 not a 86.

If you were considering buying this kit, wouldn't you want to know about issues related to it's purchase and fulfillment? Namely, not receiving parts? It's the first step to ownership, it seems right in line with what this thread is about - owner experiences. And he is an owner.

Service wise I think they're great. They tore open packaged boxes for me to double check I got everything. (Although I stated I was a pickup, but suppose that may make no difference) I've yet to install the kit but it seems like I have everything, minus the proper coupler. They've been communicative since then. So I'd say that service is good, but inventory/packing might be a tad suspect for customers. Otherwise if those things don't bother you (for many it doesn't) then I'd say it's a good kit.

Let me post all of our email conversations for the public to see. Let's let the enthusiasts decide if that's the kind of customer support they like to receive.

Just waiting to hear back from @fteightysix but you can add me to the list very soon.

Incase no one wants to catch up on all these pages, here is the helpful information I got from all of it.

1. This is probably the most daily driver friendly kit out there. Being able to drive on this kit without the supercharger working and just going N/A is a HUGE plus and piece of mind if my belt ever were to snap. First thing that came to mind is having the ability to flash the ECU back to an N/A rom and making it back in one piece, worst case scenario.

2. Customer service. Kraftwerks works with every person that purchased, some with positive experiences, others some negative due to lead times on parts, etc. Regardless, they have not been ditched. They stand behind their products which is a huge plus.

3. Some of these kits have been missing parts. These systems are all boxed up by hand, and QC might miss a few things. PLEASE CHECK OFF ALL YOUR PARTS ON THE LIST BEFORE ATTEMPTING TO INSTALL AND CONTACT KRAFTWERKS IF YOU ARE MISSING ANY.

4. Cogged pullies are supposed to be standard in the kits going forward, but some vendors may still have smooth idler pulley models boxed up. This makes it so it is quieter while idle, but still makes noise when you get on it above 3k rpm. Smooth idler pullies are just much louder. You can get these cogged pullies from Kraftwerks directly as a free upgrade by simply contacting them after your purchase.

5. Relatively easy install. Clearance with the bolt next to the oil filter is close, but not rubbing. The hardest part of the install is probably the oil reservoir for the Rotrex Supercharger as per @digital_assassin. The Forester DIT Oil Cooler has been confirmed to fit with this system. Kraftwerks is still working on an oil cooler that has not been released yet. Even as a daily driver, I'm most likely going to have an oil cooler considering I have hot Texas summers and I can have a tendency to floor it around slow drivers or someone cutting me off.

6. CLAMP YOUR HOSES UNDER THE INTAKE MANIFOLD. There are 4 9/16" hose clamps needed to reinforce these hoses under boost. There have been a few posts of these hoses popping off from higher boost 11+ PSI.

7. Catch Cans. I researched these A LOT, and saw different opinions on several ones. I suggest doing your research and using a catch can solution you feel works best to protect your engine best while under boost. I haven't made my decision on one yet, but I am a lot closer than I was.

Probably missed a few things, but I want to thank the dedicated owners for providing real life situations and issues they ran into which we all know there are issues with anything FI. All of this helped me decide this is the kit I will be going with.

Well he might have the wrong forum and possibly created an account just to post that. That's just poor etiquette. But let's say he was an frs or brz owner, it's not like his posts would no longer be valid simply because he returned the kit. He would have been an owner reporting on his experience. Returning a kit doesn't negate that.

Great summary @FR-S Matt. I'm sure lots of folks are going to find that useful.

I popped off a vacuum hose on track with stock pulley. This was also after a 80-100 autox runs this spring. Was probably working its way off for awhile.

FYI, all the Rotrex kits are similar in terms of gains, take a look at the SC shootout thread and you will see that (JR kit makes slightly more power and that's probably due to the aftermarket header )

if you're referring to the gap before the 2500 rpm I think it's because mine starts WOT at 2k RPM whereas the OEM baseline starts after 2500 RPM

for the reference car feels stronger everywhere in the power band, take a look at this dyno graph posted by KW ..I think it's a better comparison

Yes, if he was a brz/frs owner and had purchased then returned a brz/frs supercharger kit... it would be relevant. But neither of those things are true and therefor nothing is relevent to this thread. If anywhere at all on this forum, it belongs on a vender review thread.

We've got you covered @zoth, the complete kit might not be ready, but we have an partial oil cooler kit that will be available for purchase this week! Be prepared, you'll have to source the oil lines, fittings and oil cooler of your choice. Basically we'll be offering the sandwich adapter and letting you guys go from there. Not exactly how we wanted to do it, but we recognize some of you guys really want to get the oil cooler taken care of.
