No! It's not a Miata and I don't care!

Have a strong desire to slap the new Edelbrock supercharger on the BRZ.
Stock on 91oct only 245whp peak (although much better than stock NA at like 165whp), but makes 90% of peak torque from 3300 to redline and eliminates the dip. I figure E85 + full exhaust would get it up near 280-290whp which is appears to be about the limit of the FA20 if you want long-term, real world reliability and still be able to take it to the track.
Only real negative is adding 30-35lbs to the front of the car. Although you can 21 of that back with a lightweight battery.

It's a regular roots type.
Just checked it out. Kinda cool. I'm really not a fan of A/W anything, but you gotta appreciate the compactness and how this and the Innovate both look like they're part of the OEM package. Pretty neat.
I do believe a brz might be in my future when all this stuff starts getting a little cheaper. Though I'm still partial to turbo

The Edelbrock is apparently only being used 60% with a 3.25" pulley, and there are 3, 2.75 and 2.5" pulleys available.
I think they are saying, assuming you had the fuel system/clutch/cooling to handle it (obviously the stock bottom end isn't going to hold that for long either), the smallest pulley + E85 will get you up around 500 crank hp.
And as for turbo, there are a ton of great kits. Ptuning or the JDL Twin scroll setup would be proper.

The Jackson Racing Rotrex kit is CARB legal as well, makes more peak, but obviously doesn't have nearly the tq/midrange of the TVS.
JR also just released a high boost pulley (not CARB legal), fuel pump/injectors/custom tune/E85 = 380whp!!
Of course you'd also need a clutch and you'd be on borrowed time on the stock bottom end. The rods seem to be the weak spot north of ~325whp-ish. Although there are some lucky guys that have thousands of miles north of 400whp.
That's what they are claiming. They are saying it's 60% at ~300 crank HP for the BRZ, so 95% for 500 crank seems reasonable.

I very briefly considered selling the Miata and buying a BRZ and tossing my 6258 on it. If someone had been making a CARB legal kit to do that at the time I was looking, things would be very different in my garage right now.
