hi craig micks car pulled a 270 rwkws at the aps dyno day on saturday and my car is only 258rwkws so I think it may be in the tune with my 60ft time I should be killing it the only other xr6t on this forumn with a 1.91 60ft time that I know of was 100% and his car was a stage3 with slicks.....my car seems to be falling away right through the range as my 660ft mph is way behind micks car as well. Wow, that's quite amazing. Maybe someone could offer suggestions on what could cause these differences. Is it possible that the cars are tuned differently. Maybe one has a slightly different tune to protect the driveline early or is it possibly due to different factory specs before the cars were modded. Geea. Craig I am no expert far from it , but peak power does not necessarily relate to quick 60ft times or terminal speed , more to the way the cars are tuned. ie bringing increased boost in down low will produce a better 60ft time rather than later in the rev range which may produce a better terminal speed. For example max boost for me comes in fairly low ~ 3500 rpm at a fairly miserely 10.5 psi giving me a 2.01 60ft time this then tapers slightly to give a fairly sedate 111mph at the end of the strip. This is confirmed by others running similar 60ft times but greater terminal speed and better times with less rwkw Good questions , I look forward to learning some more from subsequent posts
