12.287 - 85* August
12.030 - ~40* late March

Same (shitty) track, same weight, same tune.

 

yes. get the longtubes on there and theres no reason you wouldnt be running solid 12's.

99silvy, im never guna be able to touch ap's times haha. his 60's are nuts and his heads flow better. unless my truck magically jumps .36 in the 1/8 in the cold...that and im tired of spending money haha.

so whats yalls MPH differences heat vs cold.

 

stops messing around a slap those 243' on there!!! get them milled while your at it...

 

haha probably still wouldnt touch you. i need to pay this biotch off.

 

New truck went 95mph in quarter cold and went 93 while hot.
ECSB same mods went 93mph cold 91 hot.

 

i went from running 13.3's at 101 in 95+ humid weather to running 12.6's at 106-107 in perfect 50 deg weather. i think the DA was around 0 on the 12 runs. haha

 

we need to make it out to the track this winter. i want my damn rematch. getting my *** handed to me by your hemi left a sour taste in my mouth were these runs you speak of your nitrous runs or motor runs? i think we can get that hemi running better with a few lil tricks

get the camaro yet?

 

that would be SICK!!!

 

In my experience, you carbureted guys can figure one hundredth of a second per every one degree change in ambient air temperature from coldest to warmest during the year. (Of course, this is assuming all other parameters are identical, including the engine). I'm figuring most of you are running between 13.00 and 17.00. Quicker trucks will have less variance.

For EFI motors, it's closer to a hundredth for every TWO degrees. For nitrous applications, well....that's a whole 'nother atmosphere!

I used to race a carbureted '76 L48 Corvette which would swing a full second during the season (when untouched) from 15.0s to 16.0s in temps from 40 to 105. Results would've been a whole lot different if I'd rejetted!

 

When is a good time of the year to visit SAR or Houston and get some excellent weather. I've yet to run a 1/4 mile in ideal conditions.
