So for a daily what is the most up mark +/- that the stock trans stock converter will take? I finally have all the litte stuff sorted out on my 2010 and the engine is next on the list. I don't want her to beat everything on the street I just want a really fun toy I can take trips in. I've heard all kinds of different #'s but your opinion I trust the most.

@kel6o Жыл бұрын

Did you ever figure this out? I’m wondering as well bro

@cjcoleman7372 Жыл бұрын

@Kelvin Mcgee well from what I've found out, is that the stock converter is known to go bad around 100K miles. So regardless of what you do to it, that needs replaced. The #'s I keep hearing range from 700-800 hp and will live happy'ish. It just depends on how hard on her you are or will be. Basically, there are no clutch dumps or down 3 gears and punch it, etc. This is also dependent on the transmission tune and how harsh the settings are. I was basically told build it for 800 hp and tune it for 700 hp.

A budget rotating assembly is alot different than a stock rotting assembly. Not all ls can easily do 1000 wheel on stock bottom end this is an internet myth. There are more that can't reliably than there are that can. Also the ones that do almost always go in and add ring gap and other tricks that help them handle boost better. You can't just throw boost one a stock engine without touching it and easily do a reliable 1000 wheel i would not consider that "safe" most of the time.
