First track day of the year

[exgmguy]

I headed out on Saturday to make a few passes. The first ones on motor went well.
Easy launch, no powershift, and run 12.4 @ 111 mph. I cool it down and line back up. I heat the ET Streets really well, and launch at 4500. I spin through 1st, but still manage a 1.68 short time, and run a 12.14 @ 112.44.
A new all motor best, even with a massive spring Michigan headwind.
The I open the bottle and try again. Same burnout, a 1.61 short time, but half track I notice my fuel pressure is only at 65 psi, so I coast through the traps with an 11.4 @ 113 mph.
I limp back to the pits and change my melted spark plugs. It turns out my fuel pressure regulator went bad. I would turn the key forward and the fuel pressure would prime up, then drop right off to zero.
I just made a swap to 30 pound injectors too. So I hit Ramchargers on the way home from the track and picked up a new regulator.

What sucks is that the nitrous run would have been my first 10 second slip.
