So my brother and I just got done hunting down a vacuum leak and installing some plugs, wires, and a 3.1 pulley on the GTP. We decide to take it down Hall Road in Shelby Twp. to see if we run into any KR. I shot from one red light to the next which put me almost 1/4 of the way thru 3rd gear. No KR on the interceptor and this thing pulls like a roller coaster .
Next light turns yellow so I have to hop on the brakes pretty hard. I came to an almost violent stop right next to a black SRT-8 charger, and the dude looks pissed that I pulled up on him. He crept forward a bit and revved a little on the clutch. I let off the brakes to roll up a little more and the light turned green. The bastard took off on me. He put almost a full car length on me because he stole the hit. I made up the distance pretty quickly because he spun, and I rolled into the throttle. While side by side, he gained traction and pulled until he switched gears. between gears I put a half length on him and it grew to about 2-3 car lengths by the time I shut it down.
Honestly the car sounded mean, but it wasn't as fast as I expected at all. On top of that, my car was much faster than I expected! At the next light he asked me what I had in that thing! I told him Just a little V6. He laughed and said "yeah whatever". Funny thing is... I was telling the truth. He took off again, and I let him go without racing because I had just scared the hell out of myself. (Mind you, I was testing the pulley, not looking for a race)
The 3.1 made a BIG difference from the 3.3. I can definitely tell through the entire powerband
