With the weaknesses taken care of we had to think about how we were going to get enough air through the engine. I had purchased an X51 intake, but it soon became apparent that an intake optimised for a 7,200 rpm wasn't going to cut-it at 8,200 rpm. I sold the X51 intake having never taken it out of it's box - losing a mere £500 for the privilege of having it on a shelf for six months.
With the decision taken there was only really one choice - individual throttle bodies had to be the way forward.
We had a look at what was available - a choice of one, essentially, with Jenvey making a kit. We decided to go our own way, and started adapting some BMW M3 ITB's:

Initially our thinking was to use the variable length centre section from the later 4.0 RS as a plenum to feed the ITB's:
But we may go with ordinary ram-pipes initially, more on this as we continue to develop the intake side of things.
