That air box design is pretty interesting...
But it's only 20% power gain on the crank and we hvent seen dynos yet.
Cams also make some nice peak power gains on NA and moving redline to 8800 with cams will make power at the top.
The SC compare at 500hp is a little lain considering that's probably boosting 4psi
The reckon the airbox and cams are good for another 20hp
And that's only 16whp
