Dug,
Talk to me about reading these compressor maps. They look interesting
The thing with the S2000 is that at 8300rpm, the car actually has a volumetric efficiency of 101% Yes, that's right, a VE of over 100%. Something to do with resonance forcing air in at higher than atmospheric pressure.
Thanks for your help so far by the way. As you can tell, I'm new to the Forced Induction world, after several years of looking down my nose at the "cheat's" way of making a car go faster
(when I realised that getting massive numbers out of a NA engine was extremely expensive and made the car unstreetable, I kind of changed my mind)
