As I live in regional Queensland, I do not have the luxury of having performance shops, that have built high horsepower Barra engines. So, when choosing my intercooler, I spoke to Kevin from Process West, and Alex from Plazmaman. Both were absolutely fantastic, and took time out of their busy schedules to explain the principles and flow charistics of each brand and were open and honest about the pro's and con's of each brand. In the end, I followed what the guys in the big hp cars (Spiko and Qik1) were running, and purchased a Plazmaman 1900hp cooler and supporting components. With the aforementioned gentlemen having such exceptional performance specialist assisting with their builds, I thought it foolish to ignore their test proven parts. Although their goals are much higher that mine, I wanted to ensure that I had an effective and efficient system, which would be conducive to making power. I know that their particular applications do not suit, or are necessary for the majority of users, But, in essence, the fundamentals of each cooler design would still be the same, with lower power output engines.
