i have seen a few videos which i think that one reoccuring thing with these turbo kits, is that they are on LARGE displacment motors, which means that the displacment of the air naturally occuring in the motor has the energy to spool the turbo at the rear. i mean 5.7-6.0 gto ...corvette motor, you are talking about alot of air moving through the motor off the bat
cant imagine how it might work with a smaller low compression motor, probably not as well
