I suppose I can tell you what they are and how they run. The top is a 62/14 with a 65mm turbine. The primary is a S400 with a 74mm inducer a 1.10 A/R turbine housing and a 74mm turbine wheel. Boost at 450 hp is 50 psi. With the new Smarty program on 9 and MP8 all the way up, it just touches 1400 @ 65 psi boost, even on a long pull. With a 5x11 injector, smarty on 8, MP8 all the way up and a VA C5 all stacked together with a CP3 that will make and maintain excellent rail pressure, I see about 70 psi. I did not dyno that combination, but feel it should be 750-800 pretty easily. EGT's become an issue at this level, 1600 comes pretty quick. I only ran this combo for a few runs down a backroad. With some better tuning, I think EGT's can be controlled, some water injection would definately help, as might a higher efficiency intercooler. We had a 64/14/80 single before this setup, boost at cruise speeds and spoolup is quicker than the single charger was. These do great for towing, response is really quick, streetability is great, as they respond quickly as well in stop and go traffic. That big S400 makes some good sounds too. I would rate these as a middle of the road set. Somewhat above towing twins, better response and support than the HT3B twins, not quite what a big turbine S400 or S480 will provide. For most guys, smoke is an issue also you need some boost, cruising down the road for fuel mileage. A big single will not accomplish this, a big set of twins, suffers the same effect. A small set of twins will provide this, but give out too soon. In a world of compromise, a good solution was found. A bit more than towing twins, not quite racing twins, all around twins is a better description.
