[QUOTE="Black2003Cobra, post: 1725034, member: 3159"] Personally, I feel anything below 2.93" is where you need to start addressing other issues (besides just the chip or tune). For example, below that, you really run the risk of pegging the stock MAF, especially if you drive in cold winter weather. Not that this can't be fixed (with the SCT meter or mjchips Xtender), but you should be aware of that. And of course, yes, the faster you spin the blower, the hotter things get. You might also want to look into an aftermarket heat exchanger if you're going with a 2.8", for example. Oh, and the 2.8" will likely slip unless you add idlers. A 2.93" may or may not (w/o idlers) if it is the "non-slip" design. So part of the answer depends on how much (money) you want to put into it. Also, keep in mind that the more stress you put on the engine, the shorter its life. I don't think there is a sudden "drop" in longevity if you're just playing around in the 2.8-3.2 range, (so long as you take the appropriate precautions), it'll just gradually be reduced, if you follow me. (Even at 2.8 or 2.93, you're already spinning the blower past the design max, BTW.) [/QUOTE]
