For those who run 10.5 compression and turbo what did you use as a PTW clearance? *coughbulletcough

My new setup will consist of JE pistons (2618) 10.5, ceramic coated and anti friction skirt coating.

Currently using a HRC 16g, 3" exhaust, stock head (may port the exhaust side a bit), water/meth will be used. Car is used as a DD during the summer season, so a lot of the mileage it sees will be highway. Engine temp is 180-185.

I'm thinking .0035 will be enough since a lot of the added heat will be reflected from the coating and reduced from the W/M injection, but would like some first hand experience in case it is too tight.

Even if you don't have the coating or W/M, I would still like to hear your opinion.

Thanks in advance
