I have an automatic equipped '05 3500 Dually. It is basically stock except for a Smarty Sr, boost fooler, and an intake. What key mods are needed to get into into the high 13 second range? I am in the market now for an Airdog 150 for better filtration but my goal this winter is to get it quick on a reasonable budget.

 

what are you running the smarty sr on?

i've seen 4 dr swb 6 speed trucks do 13.8 on a smarty alone

 

SW3, default settings.

 

a built trans a running the smarty sr on SW9 should get you in the 13s easy

 

I hear the term built tossed around frequently but what does that really mean friend? Seems sky is the limit and I just want enough to make for a good DD with occasional 13's.

 

minimum billet input shaft, good valvebody and clutch packs
