Well, at least with port-injection and a lower compression ratio, not only there is some temperature drop in the air intake due to the fuel vaporizing but also the aerodinamic heating is not so intense. No wonder Chevy retained the port-injection 6.0L V8 in the Silverado 2500 and 3500 instead of resorting to direct injection like it did in the 1500, not to mention the Suburban HD.
