417 RWHP and 394 TQ after UD pulley install Well I ventured out to the dyno last night with a few friends. I made 2 pulls just to see where the car was at after my dyno back in June after the cam install. This time out I installed my underdrive pulley which wasn't available when I did the cam install. I was pleasantly surprised after only 2 pulls. First pull was a 419/392 and the next pull was 417/394. The tune In my car was bang on, 12.8 afr all across the board. I may take the cats off next and see how much can be gained. So far the car has run a best of 11.60@121.88 with a 1.89 short in the middle of summer (80 degree's) . My short time's suck because I'm still trying to figure out a way to launch the car without breaking my tranny and rear end again. It's gettin much cooler here now so I'm hoping to see much more improvements in ET and MPH. I'm shooting for 11.3@122-123. now I have to decide if want MTI's new head's or wait for the AFR's, then we also have the FAST intake as well. Decisions, decisions.
