Dico,

If your engine is running= 8.5 to 1 compression ratio then your peak TIT is likely around 1625 degF a= nd therefore a TIT of 1550 degF while LOP would be about right. The stock TSIO550 has a 7.3 to 1 compression ratio and a TIT = of 1650 degF is about right while LOP. I ran my 550 turbo normalized = Bonanza LOP at a TIT of 1520 to 1550 all the time. It had 8.5 to 1 co= mpression ratio.
