Hey all. Just installed my supercharger last night and am having a issue. About 3500 rpm the supercharger is making some serious resonation noise or vibrating. does not do it before or after 3500 rpm.....Any thoughts? It is very loud and annoying. It serously sounds like somethings is not right. Anyone run into this?

go back to the dealer! ! !

did you align the belt with the idler pulley while running, if so it tells you on the manual to add shims?

double check the mounting braket on both sides

did you do your reflash?

if you can manage to do a sound clip it be nice.

well, considering there could be numerous things to check, as said by tikbhoy, i would just make it easy on yourself, just take it to the dealer, and have one of the techs drive it around with you in there, and let him hear the noise!

thats the beautiful thing about the warranty, better take advantage of it..

I know. Since i installed it at my shop i didnt know if they would give me a hard time or if they would even be able to diag it. Im getting the reflash tomorrow morning so hopefully they can do something for me.... i have triple checked everything :(

Good luck man, keep us updated with what happens :)

I will..... they just told me they need to order it :(
They are not on the same page i guess. Ill let ya know

My tC spent 2 days at the dealer for the post-install vibration hunting. It was resonating wildly and the techs agreed that something had to be done about it. They pulled the dash and foamtaped anything they could find. It's much better now, but still not perfect. When I asked them if they want to call corporate and let them know about the vibration fix they said "hell no - I'd never want to go through this process again".

So I hope you have a very good relationship with your service advisors / techs.

I guess ill see next tuesday..... reflash tool is ordered. Ill let you know what a "qualified" toyota tech has to say about it

start making new friends with the master tech of the dealer and the service manager

99% of master tech are all cock head. they never do anything for free.

LOL..... i dont want anything other then my reflash. They told my 97 bucks no matter how long it took.

Rooster head? I thought rooster suckers would be mor appropriate :rofl: Fortunately for me, the master techs at my dealer are good guys.

Reflashed the ecu this morning and the noise is pretty much gone. Thanks for all the help all! Time to go play!
