When I ran my old girl hard a couple of weeks ago at a DE it became obvious I needed to upgrade the trombone cooler. Not having the coin to go with all factory parts I got the aftermarket rig from our host. While I was at it I made a stone guard, and a couple of intake screens that I popped into my front valence to get some air passing through it.
So far seems to be a major improvement. I'll know more when it's 90º on Monday @ the next DE.
