    Who here really knows how to make BOOST?

    royceso, I am in the same school of thought with you. I believe that Rich is the way to go. Although I have been told by some other racers that "lean" is the way to go. I am just trying to get an engineering explanation as too which way is the correct way to operate.

    Who here really knows how to make BOOST?

    With that 94mm turbo and our 302 motor we can make about 1675 hp. We used to run a 100mm that made around 1850 hp. This setup with our 2600lb pro mod should run around 6.7 sec in the 1/4. We have been 7.0 but our short times are off because of spooling issues, hence the reason I am asking the...

    Who here really knows how to make BOOST?

    Thanks all, but no one has offered a technical explanation of which choice is better, rich vs lean. Are we better off lean popping in the exhaust or pumping more fuel in there? Traction has never been an obstacle, making enough power at the line is the problem. We are trying to get our 60'...

    mgeo: at 5 deg, does he change his fuel to make it lean or rich? 21 PSI, what size turbo? patprimer: NOs does work wonder but is illegal in the racing I do. So we have to make as much boost as possible and control it so we can tune the clutch for consistency.

    Who here really knows how to make BOOST?

    Here is my question. For a high horsepower drag racing application, using a manual transmission what are the best ways to make boost? I have heard of several different techniques and do not know who to believe. One school of thought says reduce timing down to a minimum - say 5-6 deg and pull...
