Default Tiger Vents

Where do these vents go? Are they for engine air intake?

I can look in there and see raw fiberglass but are they molded into a drain or intake that runs back to the engine bay?

im getting water leaking over to the cooler area and that is not alright with me. I’m pissed.

Sorry - got sidetracked. I was talking about the 2 large intake vents in front of the CIGARETTE block script just in front of the windshield. Stole this photo from the internet of a boat that I assume has small blocks in it……..

I know that boat well. It has Pontiac Tech-4s with eBay turbos.

Was on that Tiger last weekend, they’re small blocks alright. 670CI small blocks… lol

I’m not sure about the vents, I’ll text the owner.

Eric,
Those ducts pressurize the cockpit to ensure adequate ventilation for the crew at speeds in excess of 90 mph. You can just block yours off as they will serve no purpose in your application.

Let’s try this again…….they’re called NACA ducts and they feed the engine bay.
