4.8 Radix, cam, meth and new tune
Just got my 4.8 tuned yesterday. I didnt do a baseline pull but here are the current mods/numbers.
-Radix w/ 3.3 pulley, 9lbs boost
-LT's and ORY
-217/219 .533/.533 114 cam
-Stage 2 meth injection
All tuned by Excessive Autosports in Sioux Falls, SD.
Red lines are 3rd gear pull, Blue is 4th. He had to let off at about 5500 in 4th cuz there was a little wheel hop/shaking going on, I guess my 32" tall tires didnt like going 135+mph. But comparing the curves if he could have kept on it all the way to 6k the peak HP and torque numbers would have been almost the same like they were in the 3rd gear pull. We figured about 435/437 would be pretty accurate for the final numbers.
