My mods are in the sig. Currently running a 14.4 at 101 in the 1/4. I'm seeing some pretty high temps at the top of third. So the question is what would i see better gains from, dual pass endplate with extra heat exchanger or go with headers and exhaust? Discuss.

full exhaust will help a bit if you are getting knock retard, it'll reduce your cylinder temps and increase your power potential. I have a dual pass and front mount heat exchanger, dual pass is expensive and hard to install for what its worth, front mount is easier and slightly less expensive and helps about as much.

Recently when i was logging i found that my IAT1 temps were going up real high, above 108 degrees at top of 3rd gear, so i was thinking a scoop or fresh air inlet to the airbox or CAI may help out a bit and keep the fresh air coming. Its pretty much an enclosed tomb where the intake sits and still sucks air from the engine bay causing poorer performance. My IAT2 was at around 140 i think for this run, but thats with a starting temp of 108 or so starting before the S/C, imagine the possibilities if it were the same as ambient at 78 degrees, 110 degree IAT2 anyone? maybe not so much, but i can only hope.

So my suggestions are full exhaust for added performance and cooling and air inlet modification for cooler charge, then maybe a dual pass w/ option B if the money's there, but if you're strapped on cash then a front mount would be good enough to hold you over.
