This is my highest trap slip, 8.5 ET slip is somewhere else in the land of when my NT01's were fresh, lol. (Traction at this non-NHRA regulated track is worse than a standard asphalt street anyways) 18psi, was your 105mph pass still with the stock MSM rev limiter and do you think you would have run faster with a few hundred RPM more to spin? (Especially with 6-speed gearing...)

Yep, 6500. don't think so, the tiny ihi was running out of breath by 6500 and I was using flat-foot-shift so the gear changes produced a very healthy jump in acceleration anyway.
5 speed would have definitely been better, but then it likely woulda broke too.
I launched it in 2nd gear using MS3-pro LC and feeding in boost/timing after launch (pretty cool feature for drag racing).
*disclaimer: my runs were nothing spectacular either, others can do better. I'm just sharing experience for you to compare.
I've seen others trap around 110-112 with 300whp pretty regularly, that seems to be around the norm on miata's.
I do believe you should hit a 108 trap

Not sure where it originated, but its a long running joke about how to be cheap and increase compression
