We have just installed 4 new ECI Titan cylinders on our 160 Tri Pacer....ohhhhh they look nice...and we installed a JPI EDM 700 to monitor their temps/health...

We are at about 35 hours since NEW on the cylinders, they broke in almost immediately, and they are working very well. The problem is the CHT's are still a bit higher than we would like to see....430 on climb on #3, and about 400 in cruise....

We discovered that we were missing the "air scoop assembly" that attaches to the brackett air filter and covers up alot of the irregular shaped hole that the nose wheel tubes exit through. We will attach the "scoop assy." and try to seal up any additional holes in the lower part of the cowl....to attempt to keep as much negative pressure in the lower cowl so we can more effectively draw air from the upper high pressure cowl area, through the cylinders, and out the exit near the firewall....and hopefully do a better job of cooling all 4 cylinders...

We have rebuilt all our baffles, used McFarlane Cowl Saver materials, which is very nice baffle seal material, and have caulked all we can find to minimize/eliminate any air leaks, other than the two mag blast tubes, and the two scat tube connections right above #3 cylinder for forward cabin heat, and carb heat.

Our oil temps are running very cool, and we may need to adjust to a higher limit....only about 170 degrees in cruise....

We are interested in any hints, tips, modifications etc that have yielded cooler CHT's in PA22's....Thanks
