In the truck: 01' GMC Z71 Ext.Cab 5250lbs

1.80 60'

Suspension and tires 100% stock but lowered the torsion bars 1.25"

7psi boost at launch

 

1.92 with g-tech, no track times.

 

2.89

On 24's with lots of spin and traction control pulling all my timing. Much improvement is coming.

 

1.92, stock Firestones, 4WD, 2" lowering shackles in the rear. 5400#'s

 

the only thing i did was lossen the bolts 1 turn that go to the rear leaf springs give the rear sup some movement.

 

A whooping 3.32!! Lets just say I went from a Mustang to 3.42 peg leg with pizza cutters for tires. And when I knock that down to say a modest 2.1, I can say I improved my 60' times by 1.2 seconds!

 

1.90 on m/t dr's and on stock suspension. this was spraying a 125 shot and using a 3200 stall. needless to say i was spinning past the 60'

 

I ran a 2.27 with 20's and a yank 3000.

 

2.029 ecsb 2400 stall. 2" drop hanger, 3" drop shackle and spring clamps. think im hitting the axile on the frame making it hop on launch

 

1.72 at NPR(of course ) no nitrous on a set of 16" BFG drag radials with a stock g80 and 3.73 gears. Every other track I usually pull a 1.92+, but this is on the bottle.
Stock leaf springs, 3/4 drop with springs, shackles/hangers and some crappy stiff *** shocks.
