Antonov Rotrex SuperCharger
 

Alright I know this is maybe not the best forum to post it in I might even get flamed for thinking super charger. I've already discussed this and this is the route that I'm going so please don't try to start another Turbo vs supercahrger thread. The reason I decided to post in here is because all the other section I didn't get much reply.

Now to the real meat.

Alright the reason I decided to post on here is because this system is a centrifigual supercharger and as some of you know, the compressor housing it basically like a turbo charger and should react similarly. Now I've read through the FAQ sheet and I'm still a little lost, this is the first time that I go FI. To start I should probably state what I have right now. I have a fairly large SP 12A engine. I will most likely be running a set of weber carbs(might even get the fuel injected models) to run the system to replace the current holley 465. This is the dyno graph produced.

As you can tell this carb still needs more tuning but thats not the point right now. Now this rotrex super charger basically has 3 "trim"level the ones I'm considering are the C30(-64/74/84/94) and C38(-61/71/81) Flow Charts and other technical Data can be found here for the C30 trim:

And the C38 Trim is here:

Now what I would like my outcome to be, I would like to be within about 220-250HP range, This will be more of a daily driver so I don't want really crazy HP that I would have to worry much about upgrading clutch system, rear end, transmission,driveshaft and all that kind of stuff that can get pretty expensive. I would like to it be a playfull street car, with some days at the track for fun. Now trying to understand what is written in the FAQ, it seems that i have to look at mostly efficiency and RPM level. Concluding from that the C30-94 might seem to be the best suited one according to what I've read from there and if I understand things good. Some quick number from those pages for that trim level:

HP Range - 250 - 400HP
Max Air Flow - 0.37kg.s (48.94 lb/min)
Max Input Speed 10,500RPM

I'm still not really sure how to read the efficiency properly off these graphs yet. Now I plan to make the whole system with an intercooler setup nothing too large but big enough to charge the air a little cooler.How will that effect things? Now so far you can tell that I haven't mentioned anything yet about the Antonov System. The Antonov system is basically a 2 speed system that hooks up inbetween the pulley drive and the compressor side. The first speed to help the low end boost quicker, and the second speed is to help maintain the high end speed. So basically to keep the supercharger at max efficiency at all time. More info about that can be found here:

Now as I mentiong earlier this is the first time that I plan on going Forced induction, so any help would greatly be appreciated.

Just a side note this is the same supercharger that is used on the:

Freestream Caparo T1
Koenigsegg CCX
And various Ferrari's as upgrades.

Anyhow let me know what you think. Thanks
