All I care about is the trap too. Most 15' GT time slips are around
87mph 1/8
112mph 1/4

Looks like I'm making the drive in 2 weeks to see what I can actually do....

Nice. can't wait.
Yeah they usually trap 111-113

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

In for ventilated block or glory. Either will make me happy.

1993z32

Honestly, me too. Hoping for glory though. SFI 3.2A/1 jacket is on the way to my doorstep.

Don't you mean quarters and JB Weld?

Can someone explain this joke ^

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

That's hilarious. Thanks for the reference links. Brain, actually not a bad idea; as my compression gets lower and lower I'll need a way to compensate

The first link you posted is where JoeP started it. He ended making an "article" that Braineack used to host to show proof. I am not sure if the article is still floating around anywhere.

yeah. lol, it's an old reference.

on page two, we went as far as finding an "old article" from Autocar where someone successfully did it...

just add timing and ethanol.

Legendary. Now that you mention it I've seen that somewhere.

1993z32

Already on E85 and timing turned up until it wouldn't make any more power. [cries] But that's okay I just bought something REALLY stupid for my car and I can't wait to try it out.

Did you buy 4 half dollar coins?

I think dimes would be better. You could get them on the piston without pulling the head.

I come in here and see quarters JB welded to piston talk, and I feel like I never left.

OP, Great video. LOL

1993z32

Literally laughed out loud when I visualized this.
