I installed an evaporator core on the left side inlet. I can now do full throttle climbs to 2000 feet (120mph) and the water temp peaks at 180-190. Cruising around at 5600 rpm water cools off to 150 degrees. Last Saturday ran full throttle for thirteen minutes at 1700'msl 80 degrees OAT. Indicating 185 mph water never got above 190 degrees. I will post some photos soon. Thanks, Jason Hutchison ------_=_NextPart_001_01C6E241.FAC14BA2 Content-Type: text/html Content-Transfer-Encoding: quoted-printable
