[QUOTE="Justin@VMP, post: 15719328, member: 18468"] I looked at the IAT depth when we originally designed the blower back in 2010, the main concern was that it still worked and detected higher IAT temps to protect the motor. The back of the blower is the coolest "end", since incoming air cools the housing, the case gets hottest in the front where all the air is piling up. I have recorded 300F case temps up front and 150F in back when open tracking with my old TVS powered GT500. I personally don't believe the cobra intercooler is very good, nor the sensor accurate enough, to give really good transitional readings. If you have an intercooler pump fail, the engine often blows because the IAT retard function can not pull timing fast enough. I believe this is a limitation of the IAT response rate. In race applications running a lot of boost I try to pull all the timing by 200*F...i'm talking about pulling out all the timing so the engine no longer wants to accelerate. On the flip side, on a lower boost application, I have seen the 11:1 coyote engine tolerate steady 150-170F down streams with no problems for 15 minutes on the road course. I have tried a lot with the larger 5.0l and GT500 intercooler cores...from higher flow, to ice, to converting to single pass, and there isn't a whole lot you can do in my opinion except increase flow, to a point, or increase core area. The cobra core is 25% smaller than GT500/Ford GT/5.0l. Whatever you to do increase flow, you have to measure it as a system to take into account everything that creates backpressure. 4gpm is a good baseline flow rate, 5-6gpm is better, I haven't seen an improvement with much more than 6-8gpm. I will take a look at the IAT sensor depth and consider some of the input on here. [/QUOTE]
