I don't have any flow data but I have enough dyno data to know it works better than anything else on the market. The Victor is a close second but not quite as good. A 4500 intake will make more power if the engine needs a 4500 carb.
That makes sense - Hughes has data on the Victor and it flows about 314 CFM avg according to them, I’m guessing the trick flow intake is pretty close but maybe a bit better? Pretty much every other std port intake is under 300.
According to Hughes the intake needs to flow as much as 20% better than the cylinder head to not restrict power, but it looks like the only way to get there with a std port manifold is with porting. Hughes says their stage 2 Victor goes 370, which I guess would still limit power if they’re right about the 20% head room
