Right now I'm running a borrowed hx35/12 thats non wastegated hopefully mine will get back from Piers this week and its a wastegated 12. EGT's get hot on 5x5. I can peg my pyro at 1600 from a dead stop in about a quarter mile, but I rarely need to get in it that long for any reason so for me temps are not a problem for me. Rolling from 70-100 and going WOT wont get above 1200. But it does cool off fast. Cruising anywhere from 55-75mph EGTs range from 600-800 on any UFM setting. I wanted to stay with the smaller housing because of the auto, but if I had a manual I'd get the 14cm2 housing to help EGTs. Also I dont tow so I'm not sure what effect that would have on temps.
