    Vernon I'd bet your HGs where ready to go anyway. Running WOT doesn't cause them to fail. The Northstar was run at WOT for 300 hours (12.5 days) straight during the testing phase.

    Ranger, I let it get to low on coolant prior to doing WOT, that was what I was trying to say. If you're going to run WOT you had better make sure your cooling system is in tip top shape. My temperature gauge was normal when I started my pass and after about 4-5 cars and a truck/trailer I pulled in just as I heard the instrument cluster make a ding sound and it was pegged to the cross-hatches. It happened that quick. Belt drives with over 100K should just be replaced, esp. if you are considering WOT more than a quarter mile from your house.

    OK, gotcha. Yeah at WOT the water pump really speeds up and sucks down the surge tank. If you are low, it'll start sucking air and that ain't good, especially at WOT and high RPMs.
