Anybody have any good ideas for building a shroud for a mod. My guess is it will just be a get started and work it out as you go , but thought maybe there might be some stuff out there to start with that would work as a basis.

Measure your radiator...measure your fan blades, make a one sided box slightly bigger than your radiator with the sides of the box long enough to extend to the center of the fan blades...measure and cut the hole for your fan....mount shroud to top and bottom of the radiator and duct tape up the sides....otta work just fine....Hope this helps...

Make it out of cardboard and tape. Then make adjustments until you got it, then transfer it to the aluminum sheet. Save the pattern.

George is right, I've built several and it will save you time and a lot of sheet metal to build it out of cardboard orheavy paper first.

Cardboard is a lot cheaper and easier to cut then aluminim too.
I could have a whole cardboard car if I taped all of my templates together

I make mine 2 inches taller than cut it in half. Put the bottom piece on, then the top piece and rivit it together. Then when you have to work on the water pump just pop the top half off. It's so easy.

Buster are you sure you need a shroud? Don't see to many modifieds with fan shrouds and rarely see one overheating. If your overheating, maybe you have a problem somewhere else. Are you running gas or meth? Are you using a restrictor in the T-housing? How far is your fan blade from the radiator? Or maybe you just want the shroud for safety reasons.

Im not sure we need it, just playing with the idea. We dont really have a overheating problem, once in awhile it will start to warm up but for the most part I was just playing with the idea. Id really rather not have to run it if we can get away with it.
