Finally got down in the 50's in Texas this morning and i swear my car gained
20 more hp! I know cooler engines run better. just had to post this.

You know I was thinking the same thing today, and we were only in the 60's!

ya i have made a post about this too it was down to like 39 the one day it was crazy

It's not a cooler engine, it's cooler air going in. Denser, more oxygen content, allowing more fuel, higher volumetric efficiency, and of course, delayed detontation, allowing more spark advance angle.

Yep, cold air has that nice effect.

Mine was peppy, it was 32 this morning all the way down here.

I think that why they call it cold air intake

The only annoying thing with cold weather is that the tires lose grip. So there's a combo effect of 1) the engine actually making more power and 2) the tires having less grip, adding to the sensation of having more power.

You could easily see a 10% gain in power from cooler air temps. On this motor that's 25-30 more whp.

Tires will be less sticky tho'...

Need tire heaters?

I ran my car hard Sunday and Saturday nights... definately cold air changes everything. Even throttle response is better. That's why I think "COOLING" mods are most important. Better
thermostats,silicone intake and radiator hoses, better radiator,oil cooler, tranny cooler all would do a greater service to your car than all other mods in the long run. What bogs this engine down is heat. I'm not convinced that aliminum intake tubes on aftermarket CAI's will assist in bringing cooler air into the motor.

happytheman · 11-28-2011, 11:28 PM

That's why 50°-60° temps are best, you don't have that much issues with grip!

For ultimate power, buy a bag of Sonic ice, stab a bunch of small holes in it, and use it as your air filter. You heard it here first!

LakeShow · 11-28-2011, 11:35 PM

Just move to Alaska.

More kick on that spirited driving! Maybe hit up some lime creek road!
