How weak is a G56??
Well my truck has 10,000mi on it and the 1st 8000 were easy so about 1000mi a pice
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.

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.
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.

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