IDGAF abt CARB since I live in SE NM and I live in a county with zero emissions crap. The only kit I want is the bracket, blower, and possibly the piping/intercooler, if it supports enough power. I will source my own injectors and go ms3. So maybe a kit for me might be 3k, but all the other money spent to get it running will make the total cost much more.

This is my third year tracking my car. The only thing I worry about is consumables. Everybody that rides in or drives my car likes it.

Big grip kit + Rotrex kit is an easy way to a fast car.

The ecu-controlled wastegate has me thinking about C30-94 now...

That is what Jackson Racing is doing on the BRZ. It goes a long way to satisfy those who want more midrange out of the Rotrex.

They are focused on getting the CARB kits "in a box" as Oscar likes to say. The final fiddling with BOM, instructions and whatnot. The CARB kits are far and away more popular than non-CARB hardware. We have discussed the other stuff and I think they will have a similarly modular approach as they do with the Honda and 86 stuff.

This is how they have done the kits for other cars:

TIY = Tune It Yourself. Kit with out the fuel management and CARB cert
Race kit = Blower, bracket, pulleys, and ancillary Rotrex hardware. No piping or I/C

The standard I/C on the CARB kit is good for more boost HP if you get a TIY. How much more depends on your build, fuel, etc. We talked about a bigger I/C as an option for the TIY customers but that will be decided after the CARB kits are shipping in a few months.

The Rotrex C30-74 supercharger only is $2195. That's just the blower itself, the little Setrab cooler, reservoir and oil filter. That's $500-700 more than a turbo with the same build quality, efficiency and CFM.

Turbo for track means hand built manifold, DP and a bunch of hardlines. Rotrex means a bracket from Jackson Racing. The rest of the cost items end up pretty similar. The Rotrex is just so much easier to set up and tune. It's way more difficult to add power steering to a manual car

Speaking of power steering. Will the race kit work with power steering? Or is a 6 rib belt mandatory?

The race kit is just the standard 4 rib blower/bracket/pulley arrangement so its fully compatible with P/S & A/C. Just select the right drop down option to get the correct belt length. The 6 rib option will not be compatible with P/S or A/C.

FWIW we ran all weekend, 10x 25 min sessions shifting at 8000 rpm on the front straight and never touched the belt. No dust, no visible wear, no noticeable slip. A 6 rib will simply last longer. The Rotrex requires about half the power to drive as a roots type, uses larger diameter pulleys and has almost 300° of belt wrap so it's very easy on belts. No more need to keep a spare belt in the trunk than you would for P/S or alternator.

I have been running the 4 rib belt as well and never had an issue with slippage or breaking. I recently changed it because I upgraded the crank pulley to ATI. Otherwise it's a non issue.

I am glad to see the Rotrex is being revived. It's been a perfect combination for me. It was never a product issue rather a Kraftwerks issue. Now that's behind us I hope Emilio and Oscar can take the Rotrex to the next level.

For those who feel the Rotrex is soft on the bottom end can address it by speeding up the blower and bleeding off boost in the upper RPM's to protect your stock motor. There are a few ways to do this depending on how your car is configured. For those CARB compliant kits I think your hands will be tied to whatever was approved.

Word is they are targeting $4k +/- for the complete Factory Tuned (CARB) kits. Last I heard they think they can have kits shipping by January at the latest.

Must find bank to rob.
At least 4k is better than 5k... right?

4k including the piggyback stuff? If so, that sounds like a really solid deal.

Price that bitch at $3,999 with the PnP kit and I might have to spend some money... Any word on power targets? I really hope for above or right around 200hp/tq.

Thats not terrible at all. IIRC I paid $3300 before taxes & shipping with the non intercooled super barebones KW kit back in 2011.

If I was in the market for some boost right now, this is what I would be looking at:

Bell S3 w/2560: $3,549
200~ish HP, intercooled, NO MANAGEMENT, no CARB.
(Add $700-800 for an MS3 $ WBo2 or $1,500 for Xede + injectors to make it driveable)

FM Voodoo II w/2560: $3,345
200~ish HP, intercooled, Voodoo box, no CARB

FFS MP62: $4,695
200~ish HP, ECool™, Powercard(s), CARB EO# D-617

(All Numbers Estimates)
Jackson Racing C30-74: $4,000 +/-
200~ish HP, intercooled, DFC box/card, CARB EO# D-700-4

The HP numbers are all estimates based on what we all know is the top end of the stock injectors and manufacturers advertised claims. Evaluating the kits as shipped its a tie between FFS & BEGI as to who is the biggest loser here when it comes to $/hp, with FM coming out on top. JR kit is somewhere in the middle. (Having owned a rotrex I would give it mad bonus points for ease of installation but I'm not factoring that in)

As for upgradeability, (assuming the same supporting mods) I'd call it a tie between the FM and JR offerings depending on your goals. Both the 2560 and the C30-74 are going to be just fine at 250~260hp, but much beyond that and you are going to want a disco or a 2871 to maintain your top end. As we've seen the -74 is still capable of flowing more than you'll actually want on the top end.

If you absolutely need a CARB#, the JR Rotrex kit is the obvious winner.

As a Califernein who needed CARB, now you understand why I ponied up for the rotrex from KW and why I was so flaming hot when the carb cert never happened.

All the kits, NA6, NA8, NB1, NB2 will be at least a 50% power increase over OEM. Those are current projections, not final numbers.

So in the 180's for my 94? Ehh. Well I mean if it is easy to control the wastegate/blow-off thingy with a megasquirt I suppose I could just buy the kit, get the CARB EO, slap on a MS and have a reliable 200 whp that would pass inspection .

I think that's what a lot of folks will do for OBD1 cars. CARB kit + MSPNP2 + MTX WB02.

This is pretty much exactly what I'm thinking of doing. I'm actually thinking of going back to a 1.6 with this kit simply for the ease of passing emissions on a regular basis.
