FYI Vortech states not to run their units below 25f due to changes in already tight tolerances. Might be a CYA type thing, but they are a pretty reputable SC company. When it's that cold I drive my 97 4Runner and leave it in the garage. Not sure about the Eaton TVS design, but I expect tolerances to be pretty tight too - I'd ca Edelbrock and ask them about it. You could always pick up an engine warming blanket, but all that is too much pain in my ass. At this point a 2nd beater might be a better bet.

This is my third winter with JRSC in upstate NY. I also have the Subaru oem oil regulator installed. Rotrex compressor never gave any trouble. Last winter, I thought, engine tune was causing rough idle at very cold temperatures (around and below 10F). But it was fixed after replacing the MAF sensor. I don't know about the Edelbrock compressor, but supercharged FA20 has no problems. I just use 0w20 oil, warm up the engine only one minute before driving, don't go wot until engine is completely warmed up (with snow tires and icy roads that is rarely possible anyway).

+1 for this. I also have a JR kit on my car and I'm in the Chicago area. The JR kit uses a vacuum actuated bypass valve so at low load conditions, cold start included, there is no additional air from the compressor being delivered to the intake manifold.

I also contacted JR prior to purchasing the kit regarding low temperature operation and this was their response: "The Rotrex and its oiling system were developed and are made in Denmark, where they see temperatures much colder. It is fine to work in 10-20F temperatures."

Should I look into a different tune for winter?




Edit: car is edelbrock supercharged.
Pretty sure you can tune that off. Don't the OFT tablets offer a tune without this for cars with loud exhausts?

I think a tuner could do this in minutes.
