So i was wondering what does it take to get to get into the 10s?

My truck is an 08 nnbs
with a stock bottom 6.0L ly6
L92 heads
231/247 115 lsa
D1 procharger with 3.6" pulley on 13-14psi
meth injected
built 4l65E
3600 Yank PTS
4:10 gears
29" tall tire



being we only have a 1/8 mile near by, I finally had to chance to run down the 1/4 mile this past weekend in a 80 degree florida summer night

this is how she did

1.66 60ft
4.65 330 ft
7.2 1/8
92 mph
11.4 1/4
117 mph

something i do notice is i shift into 4th before the 1/8 and i feel she dies bad after that

what do you guys recommend doing to bring my ETs down?

 

Who tunes your truck? (I also live in south FL, okeechobee) With your setup, it should go 10s. MPH seems a little low.

 

How are you hitting 4th gear below 92mph at wo?

 

I saw that too and just assumed it was a 6L series. Didn't realize it was a 4L.

Maybe he meant 3rd??

 

More like WHY is it going into 4th at all? With a 4L65 that thing shouldn't ever leave 3rd at WOT.

What should my mph be going into 4th?

I thought maybe the 4:10s was the cause of that

 

Even with 4.10s and 29s you shouldn't be going to 3rd gear until 80 mph. And never shift to overdrive in wot

 

Are you sure it's not just locking the converter in 3rd? Don't think Jeremy would let it go into 4th WOT.

And IMO get a different tuner anyways. Give Redline motorsports or Lashway a call. Lashway has my buddy's heavy tbss running 10.9 on 13psi on a cam only long block

 

I'll post a video in a bit
