Just fine. The Rotrex is a proven supercharger, and is OEM on some exotic cars as David mentioned.
We've done our own testing with Rotrex superchargers (albeit on a different car) at 4000+ ft elevations, without issue. Datalogs show ambient getting as low as about 12.5 psi (vs 14.5 psi at sea level).

Not yet, but soon. My understanding is that the application has been submitted and currently under review; CARB already has the subject car.

No other kit has been as extensively tested as the Jackson Racing Supercharger.
- Oscar Jackson Jr. is a winning driver, and has been BEATING on their test mules
- There have been nearly 20k miles put on the test cars, with a LOT of them being at the track, on California 91 octane (worst gas in the country), with ZERO supporting mods. No other FI kit has had this rigorous amount of testing
- The Rotrex is ultra efficient. Th C30-94 spins up to 100,000 RPMs, and the compressor has efficiency rivaling that of turbos. Vortech blowers and positive displacement blowers aren't even close. It's so efficient, that you can go a WOT pull, brake at full ABS, run out of the car, put your hand on the intercooler, and the intercooler will be cool to the touch.
- The setup is nearly silent. This is PERFECT for those that don't want attention from other people and/or law enforcement. If you want extra noise (BOV, etc.), you can always add that on your own...
- The belt system is proven; this setup will NOT slip.
- The Jackson Racing Supercharger kit comes with a tune that has input from some of the best tuners in the world. It is the result of the collaborative effort of multiple tuners all giving their individual input for maximum output without compromising reliability or emissions. (Yes, emissions!)
- We anticipate the CARB cert to be coming soon, which is important to us out in California.
I can go on and on... I think the CSG team has collectively spent over 500 hours studying, debating, discussing, and pulling out hair over FI setups over the past 18 months.
