2017 Silverado Z71 5.3 Time Slips

Recommended Posts

Figured I would post my quickest time slips. Truck is 2017 Silverado Z71 Double Cab 4x4 5.3, 6 speed, 3.42 gears, 265/65/18R wheels. Mods K&N drop in filter, Spintech 6000 muffler, and Klug Performance tune running e85. All of the passes I launched the truck in 4wd and left it in 4wd for the whole pass, manually shifted the truck at 6200rpm in each gear. Also all the passes were full street weight with around a 1/4 tank of fuel 5500lbs. with me in it. The 13.96, and 14.01 passes the temp was 45 degrees, DA of 125, tail wind of 8mph. The rest of the passes it was 57-60 degrees, DA 625-1075, cross wind of 10-20mph. I think everything just lined up perfect for the 13.96 pass. Regardless even with the low 14 second passes I think that is quite an accomplishment from the stock 15.20 time the truck ran.

Thats impressive. I guess your running the factory goodyears?

 

Yes that was with factory Goodyears. Just switched to Falken Wildpeak AT3 factory 265/65R18 size. Also switched back to 93 and hoping to get to the track before they close for the year to get a time slip with those on 93.

That is impressive on the stock tire setup. I havent taken mine to a track. But them stock ones on mine, never could hook and thats on a all stock setup.
