Vortec Max

[whitefrost]

thinking of trying a couple of quarter mile passes,2006 6.0 vortec max,4:10 gears,hand held programmer,flowmaster exhaust,how quick should it run?

[Prokopchuk_9]

4x4???

[whitefrost]

yes it is a 4x4 extended cab,seems to pull really well,traction might be an issue,maybe!!

[Prokopchuk_9]

should do high 14's, low 15's i'd say, what kinda of programmer you use?

[Prokopchuk_9]

if youve never dragged before, your first bunch of runs will be crappy. took me a bit of time to get the tree right. if you get ur tree bang on you might hit the 14's...do you have 4:10's? or 3:73's? and urs is a 4 speed too eh? i dont know actually, i think ive watched vids on youtube of guys runnin those times. never seen one in person before so i dunno.

It should run high 14s, the 6.2 & 6 Speed with exhaust, intake & tune should run low 14s to high 13s.

These were stock times on the day of my first oil change. My truck is 2wd with 4.10 axle ratio.

 

 

 

R/T.... .626

60'..... 2.139

330.... 6.120

1/8.... 9.425

MPH... 74.38

1000.. 12.323

1/4.... 14.800

[07VMax]

if you think traction will be an issue run it in 4hi. id say high 14's to mid 15's

[Egghaus]

Wow 06sierravmax you really hooked up good, was this on the factory Bridgestone tires? The MPH is low for the ET.

[06sierravmax]

Yes that time was on the factory Bridgestones. I think I held it at 1500rpms then floored it at the light. From what I have seen and heard this is a normal time and mph for these trucks. Here are the three runs I did. The first run was fastest.

It should run high 14s, the 6.2 & 6 Speed with exhaust, intake & tune should run low 14s to high 13s.

 

There is no way that a 6.2 extended cab pickup will run anywhere near 13 second 1/4 mile times, you are talking a 5,300 # vehicle. The exhaust (cat back ) & a intake will only gain you a few horsepower , the factory exhaust actually flows very close to any of the aftermarket makers. All that you will get for your $$$ with a cai & exhaust is NOISE, not performance, a custom tune will help though

Actually, the 6.2 will crack a 13.9 or better with a good tune, intake and exhaust. Most of it comes from relieving the nannies built in for the 6-speed with the tune.

I have 6.2L with exhaust, cold air intake and Edge tuner and mine is a 4X4 crew cab and with traction problems ran 14.4 in the 1/4 mile So yes 13.9 is very reachable.
