Nitrous Limits ???????????????? I have a Walbro 255 fuel pump ! It will be tuned on motor to get the air fuel right,and a timing twister to take out timing ! I have a Comp cam,valve springs and pushrods ! What is the maximum i can safely spray to my stock bottomend LS1 motor ? Im thinking around 200 shot ??????????????
Or maybe even a 125 shot 1st stage,then another 75 or 100 shot for 2nd stage ? I usually run NGK TR6's,is that cold enough,with a big shot ? What are my limits ???????????

There are people shooting 200-225 with a stock bottom end all the time. I look at it like screwing a hooker without a rubber. Might be fun for now, but some day it'll bite you in the ***.
I use TR6's for my 200 shot, but I'm about to make the move to TR7's. Just use good fuel.

Anything over 150hp you will be stressing the stock components toward the limits. At that shot you will need to have the appropriate fueling needed and the tune needs to be spot on. There are people spraying 200+ on the stock shortblocks with out a problem but at those levels like JMill96Z said ( In different words ) you will be running on borrowed time. I woukld at least go 2 steps colder on the plugs to be safer.
