Duner, what gears are you running? I question his choice to go 4.10s ...but I am no turbo guy, so I default to you!

Turbos need engine load to spool up and build boost, right? unlike a supercharger that is RPM dependant.

would his engine be making enough power "NA" to fry the tires right through first gear, especially with 4.10s? in which case, he wouldn't build any boost "off the line"

Obviously you could trans brake or foot brake it on the track to build up your boost against the converter, but what about normal street driving?
