If it helps your decision based on quality of manufacturer, The Mishimoto radiator is manufactured by the same plant that makes Fluidyne. I'm not sure of your time frame on needing a radiator, but I will be testing the Mishimoto radiator in mid September at the Streets of Willow (Willow Springs). It is a 1.8 mile road course in which we will be doing 20-25 minute lapping sessions in the mid day desert heat. In my opinion its a perfect testing ground for semi sever conditions with the constant on and off acceleration at 18 - 20 lbs of boost, it will give it a good test. I'll be monitoring the water temps with a Techtom CMX100 with peak hold so we'll be able to see how well temp-wise it holds up.
