[QUOTE="AZ Rocky, post: 9677643, member: 64391"] If the truck is moving forward, air is passing through the cooling system and intercooler or heat exchanger. The engine doesn’t know or care if you are on the highway or a dirt trail. 100 degree ambient air is cold compared the un-cooled air charge exiting the SC. The inter-cooler will not be as efficient as it would be at 50F, however the miracle of MAF computer controlled FI will make the best of the situation. Now if you tell me a SC can't take the bouncing and shock of Raptor-style off-road driving, maybe you would be saying something that I would have to look into. However, as far as engine operation goes, it’s all about air density, and more specifically the amount of O2 you can get into the engine. Forced induction engines suffer much less from lower ambient air density than NA motors (just ask someone who lives in Colorado Springs). I know this, not because I read it on the Internet, but because I have experienced it on the street and at the track. Dyno’s are for tuning, nothing more. So you have 400HP @ 5000 RPM, who cares? What I need is torque and power in the RPM range I’m going to operating in, more like 2800 to 3800 RPM, because in the real world, we can’t drive a Raptor 90MPH off-road for very long (in fact most people will probably break the truck and/or kill themselves). But, hey, if you do, the SC heat exchanger will be working better anyway at high speeds. I agree, a modified 6.2L potentially can make far more power than the 5.4L, however, IMHO, the 5.4L is a proven engine and there are plenty of tuners out there that can make it produce more than I will ever need at a reasonable price. Just for the record, the extreme high temps you are so worried about (110F+) only occur a few weeks of the year, the rest of the time it’s pretty darn nice here. Personally, during the heat of the AZ summer, the odds of me going out in the desert just to goof-off are close to zero. It would be like you going out to play when it’s 40 or 50 blow zero; it’s just better to stay home and bench-race on SVTP!
