Quote: Matt...GREAT running Charger! My GTX HATES Drag Radial street tires!....tried my 295/65R-15's at the track once...can't get it to hook with them! I think my best 60' was a 1.72!
Just to be sure, get the car to HOOK WELL first. It should hook with a good chassis setup and weight transfer (regardless of tire). The "degree" of traction is in the tire pressure setting and/or tire compound. Horsepower is great to get you in the 10's, BUT without good weight transfer or chassis setup you are not pulling a decent 60ft time off the the line. My guess on your HP to run 10.9 - 10.8 index would be the 550-565 hp (RWHP) range (car weight depending). Just my . Nice car and good luck on the reaching the 10-sec index.
