What climate do you live in?

 

not sure if ur asking me or him i live in good ole humid louisiana lol

 

I think Scott is referring to the OP as yours is listed by avatar.

 

lol gotcha

 

Depends on what kinda racing you plan on doing. For 1/4 mile racing I don't think it will matter at all. Road Racing is another story though.
CurtD was making enough power to power his truck into the mid ten's with a 28" radiator and a single electric mustang fan. Others are making way more with much smaller. But again, it depends on what your using your truck for. For a mud swamper I'd suggest going bigger.

 

I been on 300 mile trips and no issues.. And back to back runs in 100 deg temps, never a issue..

 

I am in southwest Louisiana so it gets pretty hot and humid but since you guys are saying that doesn't seem to be an issue I feel much better. Sounds like some pretty mean trucks on here are getting by with the stocker!

Thanks for the info

 

JFYI, I am over 600 crank HP..
