OK so I"m doing a little homework and I've come down to one of these two for a new pulley system. The AEM or the Perrin. The Perrin seems to have very impressive numbers but AEM has always been good...

Anyone have any suggestions for my 04 WRX?

Thanks

Chris

 

I went wth the perrin pulley since it's not an underdriven pulley, just lightweight. I read up aboutthe pulleys possibilities of underdriven pulleys causing poblems down the road.

 

What are you running with that? What type of Scooby?

 

Its an 02 WRX with uppipe, turboback, IC hoses, pulley, amd Ecutek reflash.

B4 the reflash I was putting 197 whp. Pulley seems to be doing its job and install wasnt to bad.
