ive heard some theories and guesses out there, but does anyone have any slips of winter runs vs summer runs in the same truck with the same mods?

 

When i had my ecsb at a very low bolt on level.....lol. i ran it in weather of 86 degrees vs 77 degrees. I think the mods at the time were weather lol diablo handheld, k&n cai,e-fans and that was it.
77 DEGREES i ran a 15.2
86 Degrees same mods it ran a 15.5
If i can find the slips i'll post em but i think they are in a box at my moms = not gonna be posting them up tonight.
Now the truck i just bought...same exact mods it ran a 14.1 in i believe 65 degree weather.
I was there the night it ran this and i remember it being about 65 degrees...could be wrong but 65 rings a bell.
I ran it once i got it same exact thing but in 88-92 degree weather....some where in that range and it only went a 14.7
Hope this helps a little for ya.

 

~ 5/10's for me.

 

You were there the day i only pulled a crappy 14.7 in the new truck.
Didn't you run a 13.3 a couple times that day in the heat?
Thats 9 tenths slower than your best cold weather run...or am i wrong?

 

yes i was, lol...
it ended up going 13.20's @ 101 later on that night but remember, that was on the nitrous tune.
my truck's main problem when it's hot is it likes to pull lots of timing b/c of the high iat's.

 

I know the reasons for the slowness it was providing haha.But it helps go with the thread logic of cold times vs hot times.

 

NA setups seem to fall off around 3-5 tenths.
Not sure on nitrous.
FI setups can fall off over 1 second depending on if its intercooled, running meth,no intercooler ect.....

 

Yeah when it's 90+* and high humidity, I almost lose a second. My truck (tune) LOVES the cold, it feels AMAZING with no timing being pulled. Which goes unsaid huh?

 

yea in the morning when its in the 70s my truck runs 10 times better than in the afternoon when its 98 to 100 degrees i know some timing has to be pulled in that heat haha.

 

Mine is a whole different beast in 65* weather vs 100-110*... plus after i got through with the Speed Density tune finished it helped some...

I cant wait for winter......
