Went to the dragstrip to see if i could get better times and nope...i used to be runnig constant 14.2s,3s with just headers intake and tune everything else stock...I then added a custom exhaust and 3" drop coil springs and had a best time of 14.6...the weather was about the same of last time. Could it be the springs not transfering weight (it has major rake) or my exhaust too restricted(2.5"piping)...its a glasspack matted to a borla. Thanks for reading

 

if its spinning theres your problem. not to mention if that trucks got stock rear susp. with 3" drop in front everything is gonna be out of wack...

 

your probably right, i did notice my trucks bed going side to side all through first gear, but still managed on gettin somewhat traction, this was with 28"nitto drags at 20psi...anywho i have 3" drop springs in front and in the rear i have 2" shackels 2" leafs minus the 1"block. Could the spinning issue be because their less wieght in the back than before?...I mean the borla weighs much less than the factory exhaust, and i pulled out the tailgate and spare tire.

 

What was your 60' on you 14.2-3 runs and your 14.6 runs?

 

60s stayed about the same, crappy 2.1s 2.2s, but when i ran 14.2 i had stock 17s with 30.5" tires, and this last time that i ran 14.6 i had lighter wheels with smaller tire...Wouldnt running a smaller/better tire help my 60ft?? I guess the only way to find out is change out my drop springs for my stockers and see how it does

 

what was the mph and whats your gear ratio?

 

factory 3:73s and trapping around 95mph

 

thats pretty weird if your 60' and the weather eas the same? put your stock tires back on and go back out there?

 

just throwing out some thoughts....would it hurt 1/4 times if i have negative camber?(top part of the tire leaning towards the engine)

 

Did you check your pinion angle and did you have a glass pack on there last time? Glass packs don't flow well and could be restricting the flow.
