[QUOTE="ETO, post: 207801, member: 1486"] Boost matters but the turbo has to be sized correctly to get enough volume of air at the necessary level of boost. you can take a tiny turbo and make 30 PSI of boost but only move say 300cfm and wouldn't do anything for any engine bigger than a small 4 banger while you can get a turbo with the right size compressor housing and turbine housing for your size engine and where in the RPM range you want the engine to make its power. Remember the whole reason behind turbos and superchargers is to increase the volumetric efficiency of the engine to pack the needed air into the engine to try and get as complete combustion of the fuel. So you need boost (compressed air) but in a high enough volume to actually burn all the available fuel. An example to try and make it a little more clear Take a 100 gallon air tank with 200PSI in it hook it to a 5 gallon tank open the valve between the two tanks and the pressure doesn't hardly drop and both tanks have damn near 200psi but turn it around and fill the 5 gallon tank with the 200psi and vent it into the 100 galloon tank and the pressure goes to **** because there wasn't near enough volume to fill the tank to the same pressure.
