i know that the 63 a/r is better for a 1/4 mile but i have a 48 a/r on a xr4ti that i was thinking might work better on my ranger in the 1/8 mile. just wanting other opinions to see what others think. thanks

the .48 will spool a little faster, but you can get the .63 to spool just as fast with some mods, header, 3' exhaust,ect.

From people who have dyno tested, it seems the smaller one spools about 100 rpm faster but chokes down quite a bit on the top end. I bet the .63 would be better for almost everyone.
