Then I would be looking at 5x.012 or 5x.014. the 14s are going to be to big to run with the single arent they? I do want to at least still be able to tow my tractor around before I get the twins done.

 

14's will be alot for a super B however you cant feed them with the rotory like you can with the 7100 so you should be fine. i would recommend using a super B sized turbo for your set-up so you can have boost right off the bat.

 

Cool beans, super b and 5x.014's. When I do twins, HT3B or S400?

Does anyone know of a good tach for these trucks? Im planning a full aftermarket set up replacing the stock gauges, but I cant find a full set of matching gauges. Contacted autometer support and was told they didnt make an in dash diesel tach in 5" or 3 3/8" that would match any of their gauge sets.
