Frank..... we basically have the same Zex kit. The difference in our fuel systems is you have a ZL1 fuel pump, and I have the stock one. The stock fuel pump produces I believe around 58 psi, the ZL1 I believe produces 65 psi.

So you basically flashed the converter from idle with the line lock engaged to do a burnout. This is really no different than how I launch my car after the light drops, I do my burnout, turn the nitrous switch on, purge, then stage, and flash the converter when launching, I don't have line lock engaged of course. My car does get a higher RPM on launch from the 3200 stall.

The explosion obviously came out the cold air intake from the video....so gas somehow pooled up in the intake tube before you floored the gas to burnout with the line lock engaged. The Zex solenoid, which meters the fuel and nitrous is designed for the standard PSI from the stock fuel pump.

I think (not sure) that the higher PSI from the ZL1 fuel pump was more than the Zex solenoid box could handle since it's designed for 58 psi. Just a guess but it makes sense to me.

I'm glad you are OK and no one was hurt.
