13.40 does this seem right?

[dirtydiesel]

Hey guys, finally took my truck to the track ran 2 runs first one was 13.40 at 101 leaving at 10 psi. second one i tried to leave at almost 15 and it spun for a second and ended up running a 13.52 at 100... Does that seem right? I was kinda expecting to be in the 12s... truck is an 06 2500 extended cab short bed i think it weighs like 69?? pounds, big dipper trans SC 1054 converter fass 150 and efi live... let me know what you guys think.. Thanks

Stock turbo? Injectors? What size tires?

I would expect it to be a little faster being a LBZ. My lb7 on a built trans, efi, and fuel system went 13.03 on stock wheels and tires. Given its a regular cab so it weighs a little less.

Elevation, Air temp, traction, and tune all play a huge role in track times.

What size tune was that on? Who does the tuning

 

[unfinished business]

4x4 right? I ran 12.80 with the exact mods and same weight so u should be faster.

 

[dirtydiesel]

tires are 275/55/20, the motor is all stock and it was pretty cool that night.. yes it is a 4x4 cabel from blackout tuned it I only have a 2 postion switch and it was on the race tune.

Seems about right....I ran 13.50@99mph in my 95 Dodge at 433rwhp.

 

[dirtydiesel]

I made 480 on the dyno with my stock tranny and stock trans tune

 

[dirtydiesel]

havent dynoed it since the trans and bigger tune

 

[JQmile]

Maybe you're heavier than you think....

 

[DirtyMaxx03]

your trap speed seems low for a max effort tuned truck. I did 105 in the 1/4 with a stock trans and im 2wd.

 

[dirtydiesel]

oops i mean caleb not cabel lol

 

[joelc79]

converter lock up?

 

[FordGuy24]

Are those the first passes you've ever made? Get some more track time on it but like stated you sould be in the 12s.

 

[dirtydiesel]

I do not have a lock up switch... I might be leaning towards my lift pump possibly going bad.

 

[DirtyMaxx03]

what were your 60' times? Do you race in tow haul?

 

[dirtydiesel]

60 was a 1.91 and I did not have the tow haul on. should I have?

 

[DirtyMaxx03]

well there ya go. the 1.91 60' is killing you. A general rule is for every .1 you knock off the 60', it will yield .2 off your ET. So if you can cut a 1.7 you will be knockin on 12's door, and that is about right for the mods you have. I still think the truck has more power in it tuning wise if 100mph is all you could trap.

 

[ARbowhunter7]

^treed me.

60' is killing you. A 1.7 won't net you a 12, though. Post up a time slip, that may help. Have you dyno'd the truck since the trans/tune? That should be a 12sec/ 550 rwhp truck.

You should make sure you're getting all the air/fuel you should be. My LBZ stayed in the 13's forever with a low-12 second mod's list. After a lot of frustration, I got ahold of a Tech2 and found out my CP3 was falling on it's face and couldn't keep up with the commanded rail pressure in the upper RPM range.
