Yea, I'll have it! LOL, not! It should be close to that with the cooled Vortech... it really performs cold! It's how it should be all the time! You'll get closer with a good cool intake, see Tunable Induktions posts on here... or www.tunableinduktions.com ... :happyhapp

For every ten degrees cooler the air entering your engine = 1% horsepower gain. So I've heard.

I kinda think its more due to EFI- no choke per-se, so they gotta richen it up a bunch when cold- try with a/c on see if that gives even more boost...my 85 camaro with its tiny 2.8 v6 would freely spin the tires on a cool morning with a/c on(a/c clutch disengages at full throttle, but gm apparently forgot that in 85) a/c further richens to smooth especially when cold(at least ob a 20 yr old gm) as soon as the heater in the camaro BARELY started to blow warm it fell flat on its face, like somebody flipped a switch off- I'm talking a HUGE difference in output too, not a few percent...like a v8 vs v6 difference.

hard on a cold motor- yes I'm sure, but still very tempting...

You're probably right, ford4v429. But even with a warm engine I really notice the difference when driving below 40 degrees. Last night it was mid 30's around here and I went for a drive a noticed how extra peppy the Stang felt. I could feel the extra horses from the cold air. Let's say my GT has 275 HP at 75 degrees, just for argument. If the 10 degrees = 1% HP gain formula is true then last night when it was 35 degrees outside I had a 4% HP gain or 11 HP. For free!
