First outing (kind of a mess)
Great maiden voyage and car looks awesome! It will only get better from here and you know what direction you need to go in so that is a huge help as well. Car definitely has huge potential there.

Verdad Gallardo Thanks Adam, I shift it at 64-6500. At 106.5-107 I was right at the top of second gear at the eigth (th400, 3.31 gear and 275s). Do the math on that one! The slip of this converter is unreal at higher rpms.

Did I do the math correct on this one. Given your in second gear, don't you multiply 3.31 (rear axle ratio) x 1.48(second gear ratio) =4.899. Plugging that all into the slip calculator gave me 4.337%. That's pretty darn good. But sometimes my math isn't, lol.
Either way the car is moving!
RPM at end of 1/8th? Might give 6800-7200 shift a go to carry it farther into the next gear. I’m having the same issues with the 10” PTC. They really don’t like tall gearing and don’t couple well at lowish RPM. Even with the less than ideal gearing you have now, I bet you can still reach your goal no problem with the boost issue and 60' ironed out.

Don't feel too bad. Your ET was way better than mine after my first 2 outings, but I was able to put down some impressive trap speeds while almost killing the person in the lane next to me. You have a ton of room for improvement even though a 7.0 certainly isn't a bad first outing.
Hey 3 window, did you use cast manifolds or buy a log header setup, home built design? just curious doesn't seem like there is much benefit in lower boost levels that aren't full race setups.... looking for some great numbers out of this soon!!
