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?

 

give it hell and go 300.. just make sure the tune is on..

 

 

Probably all depend on ring gaps once you go over 250.... Parts used would have no problem holding 300+hp shot.

 

not sure if I have the guts to go to 300shot. But I will try a 225 I guess and go down to 22 degrees timing............

 

****, you can do that on the stock engine!

 

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.
