8 stack MAP is easy. Buy your intake manifold from Wayne Presley, and it's already built in.

IR systems can be a bugger to tune correctly. But once you get the hang of it, it's not a big deal. And they look just great. When properly tuned you get a nice flat torque curve that's real easy to drive on the track.

Maximum power from a maximum build engine will come from a large 4 barrel TB. That big plenum underneath gives you a better fuel charge.

I love my IR system. The look, sound, and power is just awesome. But if I want more power, that would have to go.
