I believe from memory Group A R32's ran up to 18x10J inch rims.

What are the units, please?

I was thinking more about a double cone type of air filter. I heard a while back that they can loose the internal end cap. I have never seen this personality though. I was curious. As for the temperature difference, is there any chance of a bad instrument reading?

Air filters fitted?

Any bent valves? Could be a very expensive experience...

Looks good.

I am trying to picture this... I don't suppose anyone has a diagram to share?

Efr7163 *2 at 60 lb/min vs a 9180 at 90 lb/min. Combine this with better throttle response and packaging on the v6 and there is little to loose. In my opinion... Incidentally, 2.2 x 11k is approx 8 to 9k for a 2.8 or 3.0. My thoughts then turn to a full on twin 7163 being the better bet on an all out 3.2L Rb26. I haven't seen this demonstrated vs a similar build using a maxed out 9180. Particularly in the power, throttle responses and reliability. For most folk the big single is cheaper and a better package given that you have more than enough power to overcome grip on all corners until the end of third gear! Those were 255zr17 yokos on built 2.7 running a T78. Happy memories, but a pig for the throttle response....

Twins in the oem position?

I have witnessed the Wifbitz manifold and turbo setup running in a tight time circuit time attack r32. It went like stink! As for the waste gates sounds they are muted. I was just staggered at how the beast ran.

I think that the point of variable intake cam timing is to be able to have the torque building / boost earlier (better cylinder filling... ), whilst also having a large duration at higher revs.

A very good question.

Me too, please...

Is it enough flow for the hp required ?

The smaller engine has to run at a higher boost pressure to make the same power. Therefore the position on the turbo compressor map will change. Usually to less efficiency and so higher temperature.
