In case anyone is interested my r33 was having overheating troubles and i thought it was my hub so i filled it up with silicon oil (bought from toyota) which makes it come on a bit earlier and keeps it on higher in the rev range. While my car was on the dyno trying to find out why it was 25kw down on power the operator suggested it may be my hub that sounds like its always on. Swapped it over to a non modified one and it made a whole 2rwkw extra! I'm happy to have the extra airflow minus 2kw!!
