For this upgrade we utilized LPE's CTS V 650 HP package; As mentioned earlier, it is extremely well engineered and complete. For this customer we also used Kooks headers and mids with Corsa over the axle exhaust. There was no baseline on this car but others have reported around 430 WHP on a stock V automatic on a mustang dyno. Regarding the heat exchanger, heat soak over the tuning dyno runs was pretty minimal.
