Sorry to be of bother again but I can't find (or make) a good race setup for IRP_PWF.
Does anybody have one?
Thank you.

Gus,

The best tip for this track that I know of was was posted by one of the gurus (Thiago Moya - see thread link below). He said to base it off Richmond. I tried this (in Cup, not GNS) and again played with the diff ratio (Richmond is 0.75 miles, IRP 0.686 miles so you need more torque and less top speed) and it seemed to work.

Hope this helps.

Cheers

Brad

IRP cup setup

Maybe give these a try
