what problem? boost creates a lot of heat....especially on a non intercooled setup...120-130 degree temps are great due to the methanol...
and your a/f should be around 11.6 to 11.8

my friend uses a dual nozzle setup on a YSI with 24 pounds of boost and his IAT's are in the 110 area....50/50 methanol..
I'm on an intercooled single nozzle setup and see in the 95 area ![[Smile]](smile.gif)
