| setups we are comparing; some of which would appear to put your car at the top, others may appear to put Dee's at the top, and other considerations would put mine at the top. What has led up to this post was my initial engagement in the statement that VE affects peak boost, which it does not - that's actually an illogical statement. My primary point has been that the differences we see in spoolup have 90% of everything to do with the components used in the hot-section of the turbocharger and about 10% to do with other components. The turbine is, afterall, what drives the compressor. The differences in power/torque outputs and the correlations I have made with the boost response support the theoretical presumptions that one would believe: a .86 will not spool as quickly as a .64, and a .63 with a 10-blade wheel will outspool them both. We all three have the same compressor section, so that is all apples to apples. There are variations in other aspects of the systems, but I hope that one understands that these variations have a much lesser impact than differences in the turbine or housing. It would be nice to see what your setup will do at some 30psi of boost - it will likely sail into the 700RWHP+ region, but I think making that much boost may not be possible with the .86 housing (at least, without nitrous). I also have concerns about the bottom end and midrange response. I'm really not sure, but it will be very nice to see if you guys can come up with a solution using the .86 housing that will allow you to achieve both of these goals. Going to the MASSIVEs, 2.5" piping, 60mm throttlebodies, and full 3" exhaust may just be the ticket though. :) (Damn, I really didn't want to have to pull the heads.. ;-)
