Difference between Smarty and Smarty Jr?

[dward]

I have been using the Smarty on SW 3 for a 60 hp boost with good results.

Just curious what the JR offers.

Also, any way to tell how much torque is added? I heard its double the HP.

What MY truck do you have? I can only real speak on the 6. 7L trucks and the early years such as from 7. 5MY to 09MY. I do not know if a Smarty S67 is available for all years of trucks that are equipped with the 6. 7L engine such as 2012MY. Also I do not think any model of a Smarty will be available for the 2013MY and on for a while.

Now as to the differences the Smarty S67 has 10 levels were as the JR only has 3. The even numbers on the S67 have no timing on these numbers which allow you to add additional boxes for stacking such as a MP8 box. I remember reading that the torque numbers were double of the HP numbers and these were measured at the rear wheels also they are rounded down to the closest number for both. Such as a 96 HP increase was rounded down to 90HP and so forth.

The HP numbers for the S67 level 1 30 HP increase, level 2 & 3 are 60HP, level 4&5 are 90, level 6&7 are 130 and level 8&9 are 170 HP so the S67 offers more HP options than the JR does. The HP numbers for the JR are level 1 40 HP, level 2 70 HP and level 3 100HP.

These are the main difference plus additional cost for the S67.
