Quick update...
Based on the over cooling we experienced during testing, we decided to try out a new intercooler set-up. Without adding any serious complexity, or reconfiguring the front of the car, we were able to add an air to water intercooler system and get rid of the roof scoop. We will be utilizing the center radiator from the engine cooling system as a heat exchanger rather than using it for engine cooling, then just replace the air to air intercooler with a new intercooler, plumb a few water lines and add an electric pump. Basically the same components we will be using in the street cars, but with a slightly larger intercooler core. We will be testing the new set-up this weekend, but already, the benefits are a reduction in weight (up high and out back), reduction in aerodynamic drag, lower center of gravity, and better rearward visibility. We just got back from some dyno tuning and the car made 430whp and 380ft/lbs. The car now weighs 2651lbs with a half tank of fuel and an empty cool shirt cooler. There's another 20lbs that will be coming out over the coming weeks. Leakdown numbers are still right around 10% (cold) which is what they've been since the first test day.
