i installed a 2.8 pulley awhile back and was wondering what cooling mods should i do so i dont hurt the motor

 

I have the same pulley on mine asked around and was told that if I was just getting on it here and there it should be fine but any more than that and an intercooler its all about the tune

 

I would get: Heat Exchanger, tstat, head cooling mod, expansion tank and larger radiator... that's the best you can really do.

Also don't run WOT at full boost for more then 12-15 seconds... and don't run WOT in 5th or 6th gear... period. They're overdrive gears and create a TON of heat.
