What was the temp on your 12 sec pass vs the temp at the track yesterday???

I'm going to go with weather you guys had a high yesterday of 97 degrees and over 60% humidity.... try correcting your times in the below site and see if that 13.88 comes down a bit. 20 degrees of dry heat is good for 3 tenths in my truck on the same day.

1slow01Z71 gave you some good advise with the leak down test. If you were having transmission problems I'd expect a bigger drop in your MPH. Your pushing 97 mph on your 13.8 run only 8 mph diff between your best run.

well this case the 12 was in washington state where it's not humide like here and the temps were at 60-65*'s but i ran my truck about 3weeks with stock stall and it was like 85 or something like that and ran a 60ft@1.87 and a 13.19@102mph

 

when i moved here last year in july from washington state, i think in october when i still had the tbstall my best run was a 13.56@98mph, and this was sdtune and meth (just washerfluid for cooling effects) and i was running 13lbs of boost and 12*'s of timing if i didnt have the tbstall at that time i'd probably would've seen high 12's

 

and im not having trans problems that i know of cuz i had it checked 1 month ago

 

i'll go back to stock stall, and work my way from there, im going to put on a cam, which one i dont know, i wanted the lpe gt2-3, but i think there is a better one for the radix, and springs as well

 

So maybe elevation change and temp change. Sounds like you have 13 second truck until November LOL.

I run mid/low 14's during the winter and climb up to low 15s during the Arizona summer.

i just wanna have my truck in the 12's with this weather, so what would it take to do that,

 

with which one of these would i increase my times with more a good cam for the radix or longtubes, current have edelbrock shorties

 

Cam!

Long tubes help with torque I think?

 

Did your intercooler pump quit working? I know that will effect the lightnings ET alot if it quits working? Also what is the elevation of the track?
