Track or acceleration times for a crew cab?

[diambo4life]

Has anyone taken theirs to the track or have verified Dragy results for the 1/4 mile? Interested in what Screws are doing. What is the expected time? ET/MPH? What did the 13th gens do stock?

My Screw 4x4 did 13.73 @ 99 mph last winter. It is not the lightest truck (loaded 302a with sunroof).

Damn....that's pretty good. I was not expecting it to dip into the 13s....I will definitely have to wait until November when we have good DA and run it on E85.

That run was bone stock on e85

Sport mode? Turned off any traction control or anything?

 

[PW2150]

Yeah, sport mode TC off , 4h and it seems to do better if I hold the brake, floor it , and launch as the rpm’s climb close to the stall. Maybe a fluke but this method was consistently quicker than holding the brake and gas a few seconds and launching it.

Similar Dragy results here, 3.31 gears 5.0 4hi launch, best was 5.29 0-60, and a 13.64 1/4, on 93.

EDIT: That was sport mode, TC off, going from auto hold and just flooring it.

 

[diambo4life]

Awesome. What was the mph and 60?

 

[Mike2019SCrew]

Hit speed limiter a few tenths before finishing the 1/4, possibly even a full second.

That's incredible to me that these bricks are trapping 100mph N/A lol. Just. Wow. Mine may be slower due to having heavier wheel/tire combo so we will see when I take it there in November.

 

[diambo4life]

Mine is noticeably slower to 60mph than you boys but the mph is right there with you. Also interestingly, mine has a 95mph speed limiter. It literally stops accelerating a little bit before I hit the 1/4. My best is 14.15@95mph.

I have a catback....18" wheel/tire combo and subs under the seat. maybe an extra 100lbs would be my guess.

As I am sure you know, the catback is likely to shave some weight (stock exhaust is HEAVY and the corsa stuff seems to be on the lighter end for aftermarket exhaust), the subs probably add a bit of weight, but I would consider that trivial vs the added unsprung mass of the heavier wheels/tires.

I am a little baffled by your 95 mph speed limit though, mine is 102 with T rated tires. Did yours come from the factory with S rated tires? It seems the speed limiters are set ~10mph below the tire ratings.

 

[diambo4life]

I will have to check what tires it had stock. I can't remember....I made like 3 hits and it bricked all 3 times at 95mph.

Hankook Dynapro AT2

Speed Rating: S (112 mph) Load Index: 126. Load Range: E.



That was the stock tire on my truck.

You had 10-ply tires from the factory? that seems odd, I didn't think these came with anything other than passenger tires. Maybe I'm confused lol.

Yea I was a bit off on the speed ratings, I haven't looked at those in a long time, mine came with T rated tires which have a speed rating of 118. Either way there is quite a large margin in the top speed limit vs the tire speed rating.
