Is spraying out of the whole any harder on the motor?
Still have a stock bottom end, so is spraying out of the whole any harder on the motor than my current setup which is using a window switch set with 3K -6.6K pills?

Of coarse it is harder. If it is a dead hook, the motor is going through hell to get you out of the whole. If you spin the motor is like "WOW" that was quick and isn't near as hard on one. Either way, the more power you make the harder it is on engine parts and everything behind it also. These LS1's can take some serious abuse for a long period of time though.

so what you guys are saying is cylinder pressure is gonna be more when you hit it out the whole, I dont see what the difference is when you hit the nitrous , then again i guess im just dumb..........

The higher the RPM the easier on your engine because the mixture is less at high RPM than low RPM. More air enters the engine at high rpms so the NO2 mixture is less at high rpm than low rpms. A 150 shot is progressively leaner from 3000 to 6500 rpms than a 150 shot from 1200 rpms to 3000 rpms.
You don't want to hit the Nitrous with your engine idling or just off of idle. Coming out of the hole with an A4 at 1500 - 2000 is bad.
Increasing horsepower irregardless of how it's increased is harder on the drive train if drive train components aren't upgraded at the same time to handle the extra horsepower.

i GUESS I KINDA THOUGHT THAT IT WOULD BE LEANER BECAUSE OF THE BOTTLE PRESSURE WHEN YOU FIRST HIT THE SPRAY, THEN BOTTLE PRESSURE WILL BEGAN TO DECREASE, SO IT WOULD TEND TO FATTEN UP ON THE HIGH RPM SIDE, MAYBE IM JUST SEEING THIS *** BACKWARDS, iT DOESNT REALLY MATTER TO ME , I HIT THE NITROUS ALMOST RIGHT OUT THE GATE WITH MY CONVERTER , IM NEVER REALLY IN LOW RPMS FOR LONG...

You are already spraying out of the hole if you have a 3600rpm stall converter and the window switch set at 3000rpm. When you flash the converter even if it stalls a little lower than 3600 it will still stall well above 3000 so you are spray out of the whole. If you dont want to spray out of the hole set the window switch to say 4000 or 4200rpm then you will not spray off launch.

1/4 - 12.534 @ 115.00
2000 rpm

Hitting it out of the hole is WAAAAAAAAY more stressful for an engine, there is no comparison. Its a simple matter of having to do a shitload more work...HELLO.......
