Ok, it is getting ugly and I need explanations of why this happened, but I may never get that...
My build is as follows:
Gen 1 rods and pistons in a Gen 2 cylinder.
Gen 1 springs under Gen 2 valves
HD cam chain
40 shot through 2 nozzles into the airbox.
spray comes on at 7000-11,000rpm and 95% TPS all controlled thru ECU.
Tuned on the dyno by Ryan Schnitz.
Last year I was on a 20 shot with NO tuning on a stock Gen 2 motor with NO problems at all. I ran at least 80lbs of nitrous thru it.
This is frustrating beyond anything else I have ever had to deal with.
I got 2 passes on the bottle. This happened on the second pass.
Any thoughts on why this happened?
#1 and #2 look good
This is #3. I lost an electrode off the plug on this cylinder also.
#4
