0-60's over different temps ...

[RetiredFirefighter]

Interesting to see differing 0-60 times based on weight/temps:
(100% bone stock, unmodified)

~30 deg day ...... 1/2 tank fuel ......... tools in car ................... 4.2 sec
~50 deg day ...... quarter tank fuel ... tools removed .............. 4.6 sec
~100 deg day .... full tank fuel .......... tools in car ..... ac on ... 4.9 sec

Actually, I'm pretty happy I pulled a sub 5 sec 0-60 on a blistering hot day, carrying all the tools/etc., with the ac going full blast.

What vehicle??

I think Durango. 4wd will do better in cold. In a 2wd, you need heat to make the tires stick and you can't do crap under 45deg.

Was that a DDHC? How did you measure?

The A/C compressor disengages at WOT for sure and also at some higher RPM also I think. I am sure of the WOT.

Using the oem timers or draggy?

Can't think of any cars that don't cut off ac at wot now thinking about it. Guess it's just for added performance when you floor it

OEM PP timers.

But I posted a thread where I tested Dodge's Performance Pages timers vs. Dragy vs. NHRA drag strip ... times were virtually identical.👍
(Performance Pages were actually a bit pessimistic😄)

392 with the already tested and proven Performance Pages! (see my post above)

Wondering what's more accurate?

I didn't know A/C was cut off at WOT, never read that anywhere?

Still, the 4.9 sec time was recorded during a National Weather Service "Excessive Heat & Oppressive Humidity Warning" where the Heat Index was 105°.

My test showed they were all identical.

Kudos to Dodge for their Performance Pages timers being spot on with the Dragy and NHRA timers.👍

Yes, that’s why hellcats can run aftermarket chillers and they work up until the last second
