[QUOTE="DSG2003Mach1, post: 15763019, member: 16477"] these cars definitely have air flow issues, Ive been dicussing this at length with my tuner (procharged Mach). 1) the only real fan upgrade Ive found so far is to buy a used Mark 8 fan. There are no new replacements Ive found (even aftermarket). Im 8 rib and it would NOT fit with the stock radiator (it was hitting the discharge pipe from the procharger. I had to trim down the fan shroud which hurts CFM a little but should still be better than stock. 2) I dont think a thicker radiator is going to help, this is an air flow issue. A thicker core might buy you a little more time before the rise but itll happen 3)I noticed very little difference using thinner coolant mixes and additives, it did help a few degrees but nothing major. Mine has issues in traffic with the AC on full blast (ive noticed turning the demp dial so its not full cold makes a big difference) when its hot out (high 80s and up), once the car is rolling ~40mph or so it cools right down. At highway speeds the thing runs ice cold. Im using the big procharger 3 core unit. I think boxing everything in is important, I put the stock plastic pieces back around the radiator best I could around the intercooler, dont think it really did anything but its not a good seal at all. I have also seen people using the plastic molding from the garden section at lowes/HD to make a larger airdamn (hangs down a little further and wider) where it attaches to the bottom of the radiator support to create a bigger negative pressure area behind the radiator to draw in more air through it. My tuner has said a few times he thinks the best solution may be to move to an air to water setup utilizing something along the lines of the heat exchanger you would find in a Roush blower kit for a coyote. Supposedly pretty damned efficient and doesnt screw up air flow like our big A2A units do. If you wanted to you can add some pretty big reservoirs that would accommodate a lot of ice water. Im half assedly looking into this, just trying to find a unit thats good for ~20psi and figuring out where the hell I can mount it. [USER=15250]@iismet[/USER] - any pictures you could post for us?
