Is that 1-10" per engine? Cool, the kit I got from Spectre has a plentum with dual 4" inlets on my TB. I wounder what would flow more 2-4" or 1-10". I think one 10" would have more volume but how do you adapt it to the TB.

1 per engine. We made a hoop that bolts to the flame arrestor and the hose terminates right over the the flame arrestor.
Sweet! Show a few more pics! What boat is that?
I still have not hooked mine up. If I did I would have 2 3" feeding the engine. I dont think that would be enough.
26 Spyder its a 85 Scarab 1. Did you connect yours? Any gains? I have never connected mine. I did find that the engine compartment is way cooler that it was originally. The naca ducts pull in a lot of bugs and dirt so they must be bringing in a lot of air.
That turned out great. I wanted to do something similar a couple years ago but I don't have the room with my throttle linkage.
People don't realize how much warm intake temps can drop hp!
You have any engine pics?
I will take some this weekend. I had to get a 1" spacer for the plenum to clear the linkage.
jeff did you notice any gain in your ram air????? my buddy wants to do his ???
Well, I gained about 1-2 MPH. Not bad for no internal mods. I have about $350 in the kit. If he has a easy way to route the air in then go for it. I have at least a 100hrs in the vent project. I could do it in less time now, of course. I get a lot of comments on the vents though, they look cool!!
Great job Jeff!!I'm doing it over the winter also.I have ducts on the boat from the factory that are not connected to anything but an air box in the gunnels.Here's a pic. the sir box inside has 2 4"openings on each side already.I'm going to use pvc pipe.I let you know if it slows me down.
Mine is a ramjet setup so the duct work will ride along the rear bulkhead.
