how much spray on a build bottom end finicky question, first I list what has been done to engine (2000 Vette 6-speed):
forged JE 11.3:1 pistons, Hellfire rings
Compstar rods
stock crank
ARP studs everywhere
CNC CMS heads stage 3
hefty 230/234 cam at 114 LSA
FLP headers, no cats, BB PRT exhaust
Fidanza flywheel, Specs clutch
full roller rockers
aggressive tune gave 550hp / 485 ft/lbs@ engine
full separate way oversized fuel system just for nitrous, could handle a 600hp shot if it had to be
we added a hidden nitrous system which can 150/200/250 and 300 shots.
Since NA tune shall stay the way it is for highspeed blast down the Autobahn at 34 degrees and 100 octane premium gas we installed a timing tuner and pull 9 degrees when on nitrous. We want spray in 3rd gear onwards only as out tracks can't handle a 2nd gear shot at all.
pushing a 150 shot in 3rd gear gives sort of disappointing results, even when I take time base ramp completely out of FJO. How much could be safely sprayed when we try to stick with a 11.9 A/F?

Quite a few guys running 200 shots. A guy on the truck side sprayed a 250 shot on his 6.0 I have read where a couple guys have sprayed 400 shots on the stock crank, I dont think I would though.
