Whats the diffrents

[Trim'd Up]

Thats the only differents i see too,and also the diverters inside are different.
My engine guru said the DART is best overall !!!!
Still don't know why and would like to hear more opinions.

The dividers on the merlin extend almost to the center of the plenum, the Dart is actually shorter at the bottom, but longer at the top if it makes sense. The "best" intake is gonna depend on the engine is on. The dart may make more on one and the Eddy on another. The only way to really tell is on the dyno with YOUR motor and try the different intakes.

Mhhh. Maybe, but i heard its not really a matter, actually on my boat i can't feel any differents at all with or without.
i had a 1 inch went to a 1/2 inch and also ran it with non.
same speed and response ????

But maybe i should try one of the supersuckers,,they look cool. LOL

The info I got on the profiler intake was not from the mnufacturer, but from a industry type engine building magazine. Porfiler does not advertise in this magazine either. I dont know sh*t about it, just repeating what I read and seeing if anyone had tried one. The profiler heads seem to be very popular with the big HP drag guys.
