Hi everybody,

I need to change the serpentine belt and I don’t have the right model #, or at least the size of belt. The old one has been cut and damaged, which means I don’t have any reference for it.
if anyone could help in this regard would be highly appreciates.
note: it’s v2 without any modification after installation

thanks

 

VFengineering only references an oem serpentine belt included with their kit. I would think if you call or email them you can get the size of the belt.

 

Try the supercharged 997 group on Facebook. There's a number of VF supercharged members there.

 

I contacted them by mail and they ask about pulley size in order to give me info. I have to dismantle the compressor to have the size.

 

I still don't understand this. The pulley is external to the unit and it's size would determine how long a belt you'd need to wrap around it and drive the internal impeller. The impeller is what's inside the unit and compresses the air into the intake. You should just be able to measure the pulley with a digital caliper.

 

I also have another issue, which is oil coming out from compressor outgoing through air filter, which dirt the intake and spoil the MAF sensor. And then I have to replace the sensor. Has anybody face this issue ?

 

I don't know the VF kit well, but if the kompressor bearing is oil fed for lubrication, sounds like an internal seal for that bearing is leaking and the oil that lubricates it is getting into the airflow. Likely the only fix is to remove it for a rebuild.
