Lightbulb Kraftwerks Rotrex Supercharger Discussion

I searched and apparently Kraftwerks doesn't love us enough to create a post on the popular 86 forum... I found this post on a BRZ forum:

http://www.**************.com/10-sub...er-system.html
(apparently i cant type the url that has the words subaru brz forum in it)
Showing their build of a rotrex based supercharger setup for the 86 platform.



I would assume this will come out very simliar to the litchfield setup. However they show a mounting plate that is shifted off center to the driver side which would allow a cold pipe to be on the passenger side instead of over the oil filter like the litchfield setup (which is really odd!)

Litchfield placement:


Kraftwerks placement:


Hopefully this comes out nicely. Their honda kits have shown decent numbers in the past. Maybe we can get them to start posting updates on ft86club as well on their progress! I'll send them an email and see if they can get more info.

Misc pics stolen from their other thread:

I know there is a lot of disagreement over vortech vs rotrex, lets try to keep that out of here (unless its purely educational!).

Thanks for sharing.

It looks similar to the Litchfield kit:

Ah you know what... i dont know what to call the difference between Rotex and Vortech's gear implementation. What would be the proper thing to say? I went ahead and edited the post saying vortech.

Yeah thats how i ran into it actually. I was looking up the litchfield kit and then ran into the thread from kraftwerks. The litchfield looks like it would be really annoying when doing your oil change!

FWIW: Kraftwerks site lists planned release date as August 2013. And my understanding is that Kraftwerks = Jackson Racing (same company).

Just check out the little logo before the names before you jump at me

A Rotrex uses planetary gears, and a Vortech uses helical gears.

Vortech


Rotrex

Kraftwerks was started by people at jackson racing & skunk2 but afaik they dont have any relation any more, they are separate companies. Not to mention the fact that skunk2 & kraftwerks have identical websites, hosted on the same server. (because they are both owned by Group-A Autosports

All the references to jackson racing don't seem to be on kraftwerk's website any more i tried googling really quick. All I could find were old articles about them working together but nothing recent.

It looks like they're using a second belt instead of just a longer one.

Possible pros, more packaging flexibility.

Possible cons, more rotational mass.

Just an observation. This is probably a good thing, especially looking through the hole above the rad. The intake pipe couldn't be any straighter.

The Rotrex will ramp up the boost faster than the Vortech.

Here is the dyno from my DIY custom Rotrex powered 1zzfe MR-S.
