did you move the radiator back some? hard to tell from the pics

Yeah, I had to move it back pretty far. The fan, was pretty clsoe to the water pump pully.

If anyone did something like that, they'd have to make sure they sealed upped the gaps around the radiator.

decided on the next setup

i decided on a fenderwell intake. this is being accomplished by a 3 inch carbide hole saw, piping from my DOHC Saturn's old intake, and a little tweaking. i just picked up a 3 inch coupler from the ricer section of Auto Zone today and that should be the last part i need. they have some pretty retared **** on that aisle.

here are some shots:





if i finish by saturday night i should have some numbers from the sunday autocross.

fenderwell = minty fresh air :)

took it to the autocross and i'm very pleased with the temperatures.

temperature a foot off the pavement: 105 deg

temperature measured from pipe elbow (just before the AFM): 113 degrees!

here's the kicker: on top of the huge improvement, this measurement was done STATIONARY in grid, meaning no fresh air was being forced into the bumper duct. i wasn't able to measure it during a run becuase my thermocouple lead isn't long enough, but i'll bet it was the ambient air temp.

it only picked up eight degrees on the hottest day of testing so far. this is a huge improvement over both stock and simple cone. the only thing left to do is heat wrap the intake piping up to the TB becuase it heat soaks horribly and i can focus on a better set of tires.

so, draw your own conclusions. however, the facts so far support a cone filter in any location will out perform the stock heat soaked black box and snorkel. if you really want a cold, free flowing intake go with the fenderwell cone setup. i honestly noticed a huge difference on the starting line after sitting in grid between the fenderwell intake and either of the two other setups i had on earlier. the best part? it only took an evening to install.

dynamat is for sound. besides, i think the main problem is where the stock snorkel draws air from. take a look up there. there's nowhere for fresh air to come in.
