We have a race coming up sunday that I was putting the jug on the car for..just for fun and that little umph. Nothing big..just a little 100 shot. Problem is that when i was going to dyno the thing last night to check my FP and have a wideband hooked up the shop was having trouble with their dyno. It wouldn't log a run and they had to order a new switch(it would log..then instantly stop logging). I dont have time to do it before sunday again because of previous plans. I'm just planning on leaving the bottle at home...and get razed because this kit(TNT) is now all hooked up and plumbed in so there is no hidding it..lol.

I would rather be safe than sorry and take a chance on popping this thing. What you guys think. Oh..I have a 355, forged rods/pistons, intank 255 pump, but stock crank and two bolt mains. I'm more worried about not being able to supply the fuel and going lean. I'm going to be coasting through the 1/4 anyway..too much gear

 

I am having the same delima. NX kit is on the car but no prior opportunity to check it all out. Planning on going to the track and making a few N/A passes to check it all out and then hit the button. I probably will not spray over 100shot...still got the 104s in there that are a few thousand miles old but have not had chance to change. Lets hope it all stays together!!
