i've thought about that, and increasing pulley size will only possibly raise intake temps by 20 degrees, give or take some accoding to
eaton's website
but putting a smaller pulley on means finding out the pulley ratio, and as has been posted before, if you search for info on pulley swaps the redline is very close to the max rpms for the m62 at redline, i believe with a pulley ratio of 1.85:1, making the s/c spin at 12025rpms at 6500rpms, so you could up it a bit, increasing heat up top and lower end boost, but if you push it too far and go with a much smaller pulley, you WILL fry the blower if you're not carefull
just a heads up
