Rotrex superchargers?
Rotrex superchargers? Just wanted to see if anyone knows anything about Rotrex superchargers? Just saw them in a magazine of mine but didn't know if anybody had any real-world experience with them or not?
They are centrifugal blowers, so they make their airflow in the upper midrange and top end by design. I believe the Rotrex has a ball step-up drive like the old Paxtons, but it might be a planetary. Basically a belt-driven compressor-side-of-a-turbo.

The Nova does use a twin Rotrex system on a gen3 engine. We also have a Rotrex/GM truck non intercooled kit(Intercooled will follow shortly).

Aren't these supposed to be ultra quiet and have quick spool up like a roots?
we need to see more of these kinds of setups. Kurt I'll gladly ship my car up there to get a free kit and more exposure on this blower!

Hmm. I'm DL all the info form your site. I'm planning on a Procharger build-up, but this thing looks like a neat alternative. Seems like I'd want to run 2 of them to make the power I'm looking for.
Kevin, Can you PM me some details on the Nova using the 2 Rotex Chargers? I'm thoroughly interested in this blower now that I've done alittle more then just glance over it.

They reach effieceintcy levels closer to a turbo then a supercharger because of the higher impeller speed and a higher % of effieceintcy in the island area. I belive the step up is really high to, as to achive the higher impeller speeds. Just runnin off memeory here.

I'm pretty sure they said that they wouldnt work on a F-body without some custom modification since they wouldnt clear the hood. Not 100% but pretty sure. Dont know if you are building a f-body or not Richiec77
Not sure why you would mount the Blowers that high up for a larger hood, unless you are saying that the amount of accessories moved would necessitate it. There is a fairly large amount of space by the lower portion of the block in an F-body (I have a 99 Z).
I know looking at the graphs and power levels for the versions of the RotRex's that are out now, I'd have to run 2 inorder to make the same amount of power as say a D1-SC. I'm always looking at ways to be different, and 2 SC would sure as hell fit that bill. I'm just curious on what it would take to get there. I'm going to have around $20K to spend on the set-up I'm planning, but if the costs are too high with trying to run 2 blowers, then I'll just go the tried and true route.

Hey guys,
In single blower applications the largest unit available right now is the C38-81 which will support 500 at the wheels on a decent V8
In regards to finishing the plumbing aspect of a twin kit it would really depend on your available resources and what materials you use. With the ability to make close to 1000 horespower you would want to go intercooled. With fabrication ability and a thousand or two in piping and intercooler an experienced builder could finish the kit off quite nice.
When we decided to do the twin kit it was based on the hoodline of a 69 Camaro and suited for engine swap applications. In my opinion even with a big cowl hood this kit will not clear on an F-body.
We have had a few discussions around here regarding the F-body and we think it may be possible to mount tow Rotrex units on the car but it would require quite a bit of fab work along with relocating some accessories. Considering the room down below and with Rotrex head units running about 7" in diameter I believe a decent mounting package could be fabricated.
If anyone is interested or decides to go the twin Rotrex route we have a great staff of engineers and we offer technical support.
Also, We are developing a single kit based on our truck system that can be used on Gen 3 engines in the F-body as well as the Gto and other vehicles. It will use the Bracket and pulley along with other drive system parts in our truck system but will be machined to work correctly and clear accessories. Just like the twin kit induction piping will need to be fabricated.
If I missed anything or if anyone else has any questions feel free to ask

I would expect us to have a running prototype within a few months.

ace W2W! i think rotex and yourselfs could be tapping into a market here! how about a twin rotex for the vette and other stuff??
you could low mount them and run a front mounted intercooler!
just an idea!
