The inlet area of the snorkel is smaller than that of the outlet, causing a pressure loss and the cup at the end of the snorkel will further restrict inlet flow.

I wouldn't guess what power difference removing the snorkel would make, but I can look at it from an engineer's perspective and know it's a restriction without a doubt.
Hi,

It's only a restriction if the engine can gulp more CFM than the Snorkel can provide. If the Snorkel meets this demand (which I suspect is the case), then it's merely a smaller hole, but with no consequence. You'd need a Flow Bench to say for certain. Excellent observation though...

Happy Motoring!... Jim'99
