Hey it's a "What about this combo?" thread!!!

CFM. Cubic Feet Per Minute. Total. Have a goal? There will be a CFM necessary for that goal. 1 turbo, 2 turbos,...4 turbos, doesnt matter how many compressors are in the loop...what matters is CFM of airflow.

Like what I keep saying. There is a relative airflow requirement for base power, and power on boost....that airflow requirement goes up for each 100ft/tq you want to add to the equation.

If your base engine makes x (350hp), you need a turbocharger that will add another 650 cfm of airflow at 14 psi and 6500 rpm....to achieve 700 (double) hp.

So you look to size a turbo that will flow 650cfm, or a pair that will each flow 300-400cfm and adjust boost pressure to necessary CFM airflow.

That is why a goal is so critical.....if your goal is ultimately 1000hp+...you dont want short change yourself and have to refab.
