I have removed the cover simply because I like to see an engine when I raise the hood, but if I iced the intake I would hesitate to claim it as a stock time. Most people probably find that ridiculous, but for one thing I feel like being so strict on myself about stuff like that gives me a credibility few can claim. Now, I will try using a pump up sprayer with rubbing alcohol to cool the engine and radiator down, because that can't cool anything much below ambient temperature. It's really just a time saver by reducing the wait for cooldown between runs.

To answer the question about shifting, you can't shift at any higher rpm than the truck will do by itself. The gain comes from getting access to 2nd prime when you shift manually. According to my tach, it shifts at 5600 rpm at wide open throttle. Doing it manually, you need to command the shift at about 5400 or 5450 to give it time to react. If you wait too late it hits the rev limiter until the shift happens, which slows you down.

you really think that icing the intake makes that big of a difference? ive iced the intake on the stratus, and not iced it, and i didnt notice any improvement in my times...

I know muscle car guys that used to do it and said it helped. I think you could get a 10th or so, but not much more.

Thats why just about every body out there with a GTO or and srt or 5.7 hemi that drags it, has a 180 degree thermo, and either a modification or a tune to turn on the fan earlier at lower temp.
theys say for every 10 degrees over 190ish you are---thats a loss of ten HP. Don't laugh-I have launched my charger srt8 at 200 degrees and got a 1.92 60 ft. time and only ran 13.0. Cool off the car, including ice on the intake, get a 2.1 60 ft time and run a 12.8 cuz the car launched at 175 degrees. Makes a huge difference.

Its about the temp at launch--and yes, in these big V8s it makes a huge difference.
