The HE is inside the IM? Guess to save space?
Why not a better A2W IC, larger core outside of IM, bigger pump, larger, dual pass HE -- water is much better than air at absorbing heat...
Or, if it can be done, figure out how to incorporate a roots or twinscrew (clutch engagement?) and ditch the centrifugal blower altogether.
I know am just daydreaming here...
