I've bought a used (25.000 miles) ROTREX C30-94 supercharger for my Gtv 3.0 V6 24v from a member here (from Poland) who told me it was in very good condition and worked properly.
The kit has just been fitted (one month ago) by my mechanic (now 333 bhp) and at cold start I have a noise that disappears when warm. My mechanic also told me it was not in so good condition and it seems in Poland they have salty roads because of snow in winter and some parts from the supercharger kit had some rusty points.
Here is a video of the noise :
(i already put some WD40 lubricant near accessory belt and i replaced supporter's supercharger bearings but the noise still there). Oil's level is good from rotrex radiator and oil is new.
The seller is telling me the supercharger is subject to wear (
) and I have to send it to ROTREX (Denmark) in order to change the internal bearings... Too bad the warranty is over and ROTREX doesn't seem to fix or rebuild them...
Although it was used, i had in mind to drive my car at least a few thousand miles without any troubles...
I found a american company who rebuilds them :
The bill is 650$ including shipping charges and 500$ more if planetary rollers have to be replaced...
What do you think about this noise ? Can I drive like this (no more noise when warm) ?
Do I have to buy a new one (on ebay there are some sometimes) or only to check the noise ?
Needless and useless to say i'm angry about seller's behavior.
Thanks for any advice or feedback about ROTREX superchargers.
