I have an ap2 that makes 240whp with very similar mods as yours and ran a 13.6 at 101 with a 2.0 60'... something doesn't add up... if i cut the 60' by .1 sec and shed another 200lbs(.2 sec) i would be around 13.2-13.3 and probably only 103mph... I don't get how you can rip that 60' time and still trap 107mph... crazy lol.... ahhh wait but i did have 4.57 gears at the time so i was shifting into 5th... your ap1 probably hit 107 in 4th... i've wanted to go back since i recently switched back to oem gear ratio... I tried just bouncing it off the limiter in 4th and only ran a 13.9 at 97mph lol

I can look up the weather on the dragtimes app and see what the Density Altitude (DA) was during that time. 1000' of da change is roughly .13 sec and similiar mph. What rpm did you launch at? A bogging 60' will slow your mph a bit. How fast are you shifting it? You also have an extra shift. All of these things are big factors.

I know 4th gear in an Ap1 trans can go out to approx 117-118mph max, bouncing off the limiter. I believe i set my limiter at 9300rpm
