I would say that the 25% the car is classed at -- given the 30% default for multivalve motors in ITB/C -- is on the high end of what is reasonble for the car. Again, I disagree with it, but it isn't totally out of line with what could truly be the case for the car and gains in a full IT build.
At this point, my personal opinion is that the car is not going to be looked at again barring something conclusive like 3-4 guys building maxed out IT motors with full discosure on the builds, and submitting dyno sheets at less than 20% gain.
Again, my personal opinion is the car is heavy, and it is a shame because it should be one of the mainstays in ITB. But it is not so out of whack with the "fuzziness" built into the process so as to be totally uncompetitive.
