    No.
    I pulled out the factory breather than tapped the hole for a pipe nipple. I took a hose with a cheap metal fuel filter on the end of it and ran it up to the trunk floor. No further issues. I have been on track for 40 minutes at the Vegas outside road course on a 95 degree day with no puking.

    I've been wanting to add one of the coolers like they have on the new Shelby mustangs to something. Its an even nicer setup than a catch can.

    I don't think I need a cooler. I just need somewhere other then the bottom of the car and road to go when the fluid is expanding when I'm pushing it hard.

    First I would use synthetic fluid. It runs cooler and expands less with heat so it alone might take care of your problem. Next, you can use the 4wd trick. Instead of putting the breather in the differential, put a length of rubber hose in the differential and extend it up higher on the car somewhere. At the other end of the hose, put the breather. The extra length of hose provides a small area for fluid to be stored if pushed out of the differential.
