The more the merrier!
Testing continues, currently playing with the E70 available. So far so good. Should be back to the dyno in the next week or two if all goes well. Current tune shows the following on the g-meter with e70:
Overall higher and more consistent. After finally getting a BRZ and really putting some miles on it, that dip bugged me even more. Buried in engineering papers the last few weeks I'm pretty confident that it is about as good as we'll get that dip with stock cams/header/intake manifold. It is mostly a cam issue, but tuning does absolutely help.
Below is a torque/HP curve of an MX-5 (2.0l port injection) vs the BRZ (early prototype tune).
Note how they are an inverse of one another. You can't have it everywhere, even with continuously variable dual VVT. Note the FA20 dip is really the up top HP. I'd have to agree subaru/toyota figured you'd be in that range the least. Either getting down low torque putting around town or all out HP on the course or track.
E85 opens up a whole slew of possibilities here. I have it set now that it is map switchable and not needing the sensor; however that route would still be more ideal. Auto-x rules don't permit it for the particular class we're worried about here, not to mention it is rather steep at the moment.
