So you didnt measure actual IAT's, just the temperature of the pod filter?
Also, please explain how you measured the torsional rigidity of the car? with a tape measure after hopefully jacking the car up in the same spot?
To add to above, the R35 uses two small separate intercoolers, not one large one, so the flow distribution is not a big issue.
But yes JZA70 intercoolers arent that great, but work fine for a streeter
They way I look at it is: The WRC and Lemans spec Garrett motorsport turbos run a V-band housing.
Surely if there was a huge advantage with the twin-scroll turbos they would be using them
