well, seems to me my car reaches max speed about 2/3rds down the straight on our track. Which I thought was the perfect point. Since the guys running lower FDR are overheating and since when I rean a 5.2FDR my temps were much lower. I assumed going any lower on FDR would increase temps even more giving me a problem over heating. Maybe I am wrong here.
This is all still with the 13.5
