I dont think it requires much effort to get in the 13's. My G56 shifts lightning fast and I run high 13's with my 07 with just the mods in my sig.

Nice! Which sb turbo do you have? Was that on the 20's

What gear to do launch in and what 60' were you pulling?

Not that I have found I know that John was looking into some type of retainer that would help but i dont really know!

Well my truck has 10,000mi on it and the 1st 8000 were easy so about 1000mi a pice

I know several guys with G56 failures. 500hp and up with a little abuse, drag racing or pulling, and your probably on borrowed time. Tac

I have the 66/74/14. Yeah that was on the 20's. Ive only run my truck once on the track and actually I ran a 14.4 at 97mph. But that was with a horrible launch, I had just got my SB on and I was used to launching with my stock turbo. With the stock turbo I would just rev it up and dump it in 2nd gear 4wd and it would launch like a bat outta hell.
But SB doesn't spool nearly as fast, so when I tryed the rev it up and dump thing it just fell on its face. Also when i hit 6th gear, the stock clutch started to slip pretty good.

So I believe that with a good launch and clutch that doesn't slip, my truck would definetly run in the high 13's.

Don't say easy 13's till you get there. It takes a lot of skill to hit every gear perfectly on the one perfect launch in five or so attempts. On the night I ran 14.40, I also ran a 14.89 and a 15.3 with the same tuning.

You might want to give the new transmission a chance to wear in. You know how tight they are for the first few thousand miles.

I havent had any problums with my G56 Pull close to 40K sled pull and have 37's. With a little over 60K
The only transmission I had fail was the NV5600 in my 04 so I have a hard time believing the NV5600 bulit proof talk.

Bad-Duvall

I sure hope they werent tight! never should they be and if they are you did something wrong!

Do some talking to the serious pullers. The only real problem with the nv5600 is the out out shaft. The G56 is to week for even a 600hp truck on the road.

I realize that but I've played around with my truck way too much on backroads and stuff and I know what it will do. This G56 shifts pretty sweet, its a night and day difference compared to the nv4500. I guess you would have just had to been there to see just how bad I launched. I was lined up with an 05 RC/LB 6.0 auto powerstroke with stacked chips and when we launched, he left me like I was standing still and got several truck lengths in front of me. But once that SB lit, I ran him down and beat him. He ran a 14.5 at 94 and I ran a 14.4 at 97.

I just need a good clutch so I can launch it right and not slip once I get in 5th and 6th gear.

Interesting... How much power you pulling with RamRodd?

Never dynoed my 06 so I cant say for sure. I did dyno my 04 that had 420 hp and 818tq. I do know my 06 blows the doors off the 04.
I would guess 500 and around 950ish on the TQ. I will dyno after I get the twins on.

I don't know if its schere luck, or I got a good one, Or mines gonna die anytime know. I have 20+ Hooks on mine 15 over 650hp With and tons of boosted launches and darg races in the mid to low 13's @ or around 108mph trap speed. So who knows... I have a few friends who have killed a few as well

Tacsavage

Maybe you will be one of the lucky ones and never have a problem. My little brother (unrulynfs) wasn't so lucky with his. I feel bad for him because he has broke so much this year, he is afraid to turn everything to kill.

kruegerlouie

i know of a guy in kansas that runs over 800 and pulls,think he went through 3 or 4 this past summer!!!! he says he would be haullin for the end of the track and 5th gear would explode. was lookin for a 6spd(got auto), and VERY happy pulling with my billet goerend 48re last summer

bluechrome

If I do anything it will be an auto conversion. Pry my next big mod
