[QUOTE="hopony, post: 14357644, member: 153219"] Just got back from track. Car ran a best et of 11.00@124 1.52 60' [video=youtube;eE_mfnwyBiM]https://www.youtube.com/watch?v=eE_mfnwyBiM[/video] Now that being said something is off with the car and I am not sure what. Setup is a Beefcake Special 3.8 pulley, SW headers, Bap, 3.31 gears and 28" M/T stiffwalls race weight is 3880. Dynoed 607 whp last year when I installed the blower ran 126 mph on street tires 1st time at the track. Did re tune yesterday same tuner. dynoed 597 on old tune before we started tuning it. Did 610 on new tune. My goal with the car is to run in the 10's and trap 130. So we tuned it with some 104 sunoco 260 gt plus and gaind 57 whp, but the car did not gain any mph or et at the track. If i put the time slip from the old pump gas tune and the race gas tune you could not tell them apart. According to Wallace racing calculator car should trap 129 with changes. I am at a complete loss with the results. Old tune pump gas video [video=youtube;wr0_dPJvVlM]https://www.youtube.com/watch?v=wr0_dPJvVlM&list=UUNx_PA1r2GUGSYRgWPRt54g[/video] Since the car ran an 11.00 we took off the air filter trying to get in the 10's it did help mph, but still came up short. New tune no air filter [video=youtube;NVRCifWNYac]https://www.youtube.com/watch?v=NVRCifWNYac&list=UUNx_PA1r2GUGSYRgWPRt54g[/video] [/QUOTE]
