I can tell you that I lost a solid 50 degrees up to about maybe 75 degrees pre-turbo with this turbo compared to a PDR35. I used the same 14cm wastegated housing on both of them. Running at the 300 rwhp level I won't get above 1200-1250 from a standing start. Standing on it above 60 mph will only get me to 1100. running at about 340 rwhp I see temps around 1375 from a standing start. I havn't tried above 60 mph yet. I usually run on the 300 rwhp setting so EGT's will never be an issue. This is a good turbo for the HP that I am running.
