Howdy folks, I just put another turbo on my truck and my exhaust temps have me very puzzled. My mods are in my sig and nothing has been changed except turbos. When I was on my stock turbo I could push it to about 55 psi, but my exhaust temps were only around 1600 tops. Then I went to a plain jane s300 with a ported 16cm housing, it ran hotter than the stocker during normal driving but on top it also ran about 100 degrees hotter, would make about 40 psi of boost. So tonight I installed a B-1 62-14 charger, in hopes of cooling down up top a little. Well much to my suprise I took off for my test drive and pegged my 2000 degree pyro at about 45 psi of boost. What am I missing here folks? I'd always understood that a larger turbop while it'll run hotter down low will cool better up top? Can anyone please explain what's going on here? It's got me flustered cus at this point I was honestly happier when my stocker was in.:bang
