New JRSC install, sounds normal?
Hi Guys,
I've finally bite the bullet and got the upgrade, but I was not expecting the obvious whining noise coming from the unit (is it from Rotrex or belt?), can some of you share your thoughts on my setup and let me know if it's "norm?" cold start https://youtube.com/shorts/iK5m8neBsEo?feature=share warmed up https://youtube.com/shorts/jISghmF6E6w?feature=share i found another video on youtube when they had their Rotrex unit replaced: Since mine is a new install, i want to make sure it's done correctly early on. Thanks all! |

Not normal, imo. I drove a JRSC brz and it didn't have any strange high pitched whining at idle like that.

Is this new or used? You said new install, not new parts. This isn't normal

I have heard other JRSC owners at car meets and i don't recall this obvious whining. Any JRSC owners if you coming out to the next group SJ meet let me know! |

i would expect the noise to match the rpm increase as he is doing in the first video, but it s only at idle and then seems to disappear, so it seems more related just to some resonation within the bypass valve

At first it sounded fine inside the car but when you opened the hood it sounds like a failing refrigerator compressor. My re circulation valve hisses but it also doesn't sound like that.
Did you end up bleeding all the air out of the traction fluid tank? It took me a few tries to get it all out. Maybe you have air trapped in the lines? |

Sorry I didn't mean to imply that it is the compressor making the sound, I mean that the sound you have sounds like that for some reason. Honestly I don't know what a rotrex sounds like that is low on traction fluid but that is the only thing I could think of. I'm not sure how the shop installed it, but if they gave you back any traction fluid it probably wasn't bleed right. It took the whole bottle for me to get a good bleed out. What does your dipstick read? |
