Jackson Racing C38-81 Supercharger - CARB legal

[mistople]

I happened upon a One Take where Matt Farah was testing an AT with the JRSC. He mentioned that he felt the SC maintaining boost after throttle release for ~1.5". Is this a known behavior? If so, has it since been resolved?

He isn't the most knowledgable person and often blabs incorrect stuff. It is not a issue.

Just charge pipe fitment on the 86 bumper; the existing kits fit on a 2017 BRZ.

PM me to order.

That can happen if the bypass valve is damaged, leaking vacuum. With a working bypass valve boost is recirculated as soon throttle is released. A broken bypass valve can damage the compressor because of surge.

Sort of an out of the ordinary question, are quick intermittent voltage drops expected when on throttle with the C38 SC?

No. Sounds like you may have other electrical gremlins.

Really? I would of thought since the the SC takes some parasitic loss from all the pulleys like the alternator, however insignificant it may be.
The volt drops are very quick and minimal during 1/4 throttle or so, dropping from ~14.4v to between 13.8 and no less than 12.8v or so then as soon as off throttle they immediately shoot back up.

That's what's supposed to happen. Electrical systems in cars are designed for 12V. As long as you're not under that you're fine. Any basic electrical system will drop voltage when it is put under load unless corrected by the supply.

Even if the alternator has "minimal parasitic loss" the battery still provides voltage to the car.
