what did u break on it

 

crank

 

nevder heard of a crank letting go so far

 

i spun way too many rpms for a long time in excess of 4500 rpms and sled pulling not bueno

 

I've seen some spin that hard but not without some well massaged internals

 

yeah, everything on my engine was stock

im a good beta tester

 

have any secrets 4 the dragstrip I can't seem to break into the 12's when i launch it seems 2 just want to throw the truck around alot tie-rod sleeves were supposed 2 help but dont think they did

 

Different shocks maybe? I'm not a duramax god but good shocks are always a good thing. Maybe look up qa1 shocks. I'll have to dig for the site. They where more than willing to help with my friends mud drag truck.

 

you have to lower the tbars just about all the way down, when i launch i leave at 1800-2k rpms. anything more than 10lbs of boost and ill break all 4 tires loose off the line.

when i ran my truck back before i did the motor swap and put stock bumpers back on i did o track prep what so ever and managed to get a 12 with the truck weighing 7200lbs.

do you happen to have a log of your track runs? how are your 60' times they play a big role also.

theres a bunch of little things that can be done here and there also, but logging and seeing what can be done with the tune can help out also. tuning at the track is great

 

i have the original shocks on my truck with 150k miles
