You need to put in a bypass hose. Rick and I had the same problem with the dual outlet Weber manifold. The temp would not go over 140 on my ERA. I tried different thermostats like Moroso and Mr Gasket, nothing worked. I tried a regular thermostat with a 3/16 hole drilled through the face and the temp would not go over 170. I put in a bypass hose with a Mierze inline thermostst housing and a Napa Super Stat 180 thermostat and it works fine, stays at 180. The ERA radiator is huge.
