Dr. Lee,
I have increased the fuel setting on my 93 6.2 NA hummer by 1/6th of a turn. This is after changing the air filter to a K+N and getting rid of the factory muffler. The NA hummers have a good flowing intake manifold, headers and 3 inch exhuast already, not to mention the intake tubing is 4 inch!!! After this fuel increase I see only the tiniest amount of black smoke and the power increase is very noticeable. My next two steps are the performance cam you mentioned and 4911 pump with TD injectors. My factory HP rating on this engine is 165 according to the sticker on the valve cover, I think I may be near 180 now. Do you think it is possible with the cam/pump/injectors to reach 190-200 HP and 375-400 Ft LBS? I am impressed with the 6.2 NA in my hummer, it used to be very slow but now has some pep, but as always I am itching for more. What kind of HP/torque do you estimate your little red hot rod is putting out? I am interested to see if after the cam/pump if I can race and keep up with a TD hummer. If I do find one to race I will be sure to let everyone here know.
