You might be interested in knowing that almost all aircraft turbos have A/R greater than 1. Most are designed to make up the mp drop as altitude increases so that performance does not drop off. Got any ideas for me? I have an HKS 20B ss manifold w external wastegate (a la the souped up Cosmo 3 rotor car), however it does not allow standard turbos to mount far enough away from the intake tubing, so I have to make an extension to get it farther away.
