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.

I guess that means it's Dyno season. Get your Dyno runs in now so you can put higher numbers in your sig and gloat all next summer when people are doing pulls in the heat

Jordo! · 11-28-2011, 10:33 PM

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'...

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.

I can agree with this, i felt the same way about a lot of CAI's, that's the reason i bought all of the silicone hoses available,including the post MAF hoses ( of course, i didn't need the breather hose set). I'm very glad Z1 Motorsports had that nice black friday sale, ordered the K&N air filters too. Now all i'm waiting on is delivery of my girl Vanity.

You said it best with heat being the most cause of hp loss. Good Point UNKNOWN. Not a lot of people get that one
