driving the truck when it's 65 degrees out verses 95 like normal...
WOW is all I can say. It is like adding a 50 shot of nitrous. I dont even know how to explain it. But I will try.
I put the 4# pulley on last spring and when I installed that and ran a chip, I had the biggest grin on my face. But I wanted to go even faster. (12.64 @107 was my best) So I got a single blade, 90mm mass air, a set of slicks, and traction bars. And I got an interchangeable upper, 2.80. I put them on end of May I think. But the weather was always in the 90's if not higher here in the summer in Illinois. So the truck did pull harder and with the new intake set up it was more throttle responsive. But my times can prove it, it's never went faster than 12.64. I went 12.7 and 12.9 a few weeks back with my current set up. But it was 80-90 degrees out that day.
Tonight for the first time since I did my 2nd batch of mods the weather was below 90 degrees. It was actually 65 degrees out. Perfect Out! So I took the truck out after taking the slicks off and putting back on the f1's. The truck felt like I added a shot of nitrous. I dont know any other way of explaining it besides the truck finally feels like it should after going from 12.60 and adding the batch of mods I did a few months ago. But running around in this 90 degree heat is nothing but bad for the truck! Tonight was awsome! I couldnt put the truck in. I wanted to stay out all night but I was afraid I was going to break something or end up in Jail.
The truck took off like it had a gear, it chirped 2nd. I was reading 15#'s of boost on the autometer (the blower was screaming) and then I chirped 3rd!
The truck has never ever pulled like that ever b4.
I just can't wait to get out to the track. Every time I think about going out there it's way to hot. I think I will have to wait till the end of summer or fall even. But after that preview tonight I got, I don't mind waiting... thanks, shane

Do you mean you chirped on the 2-3 shift? Chit, I've done that a few times, kinda scary, especially when you're already doing 70+ mph!!
I know what you mean about the kick in the a$$ from the colder weather! These 90+ degree days are just KILLER on the Ls.
Can't wait to see all the new 1/4 mile times this fall with all the new KBs and other go-fast goodies out there

Shane,
Below is a link to a calculator that gives some idea how air conditions effect hp. 'Standard' conditions are mentioned in the text.

The relative horsepower calculator/relative humidity that pops up with the link is useful for showing how different conditions effect power. It is given as % of standard.
For example, a 100* day with 29.5 barometer and 80% humidity at 1,000 feet elevation, a truck with 400 hp under 'standard conditions' is making 88.6% power, or 354.4 hp.
Per the calculator, on a nice cool dry winter day (40*, 31 barometer, 15% humidity, 1000' altitude) the same truck makes 107% of 'standard', or 428 hp.

thank you for inputting the #'s. Say I am 400 horse on a humid day im only making 350 and on a cool day I can be making 428? More than normal just cause its cooler out and the air is more dense?
if those #'s are correct and they are right down my alley, last night I was making about 78 horse power MORE last night cause the cooler weather. does that sound right? (428-350) 78hp more than running like normal at 90-100 degrees. do I understand that right? thanks, shane

Shane,
You got it right. I know for a fact that a SC loves cold air over hot air any day. Down here in Texas NOS is huge since it loves the hot air more then a turbo or SC. I was thinking of trying to make som kind of intercooler to shove cold air into the SC since its to damn hot here in TX.
Just my 02.
