    Install a thermostat with a higher temp. opening point. Or block the radiator with cardboard is probably the easiest way to keep the water hot.

    already put in a 195 tstat, it helped about 5 degrees.
    If I could figure out what relay to pull thats help along with cardboard.
    Ill try pulling rely #3 and go to work see if that helps.

    Honestly my fans hardly run in the summer. They never, and I mean never, run in the winter. But I don't let my car idle for any longer than 10 to 15 mins.

    Just backflushing your heater core could get you slightly better heat, and can be done without flushing the whole system. Any amount of buildup will lower coolant flow through it and limit your heat output. It's worth a try to avoid pulling relays and such. If that doesn't work, I'd do what Bill said, reprogram the fans to come on at 195 like they should.

    Has anyone ever done controlled testing on how much 180 degree fans and thermostats really help KR? I bet they don't help much at all compared to headers and other mods, so I'd consider 180 degree settings and such pretty pointless.
    For thine is the Cam, The Piston, and The Rod, Forever and ever (or until they break). Amen.

    ^probably not much of a kr difference. Cheap enough to try though. Supercharged cobalts come with a 180° thermostat from the factory.
