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?

As long as you are full throttle when you hit the spray and can hook it up , I cant see it being harder on the motor, but on the tranny and rearend I can see.

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.

Engine... quite at bit more harsh...

Rearend... from a dig.... .... with a good hookup...

boomcase

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..........

Because the engine isn't turning as fast out of the hole.

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.

Believe it or not the window switch has alot to do with the 60ft. I took a cutomers car that had a SS3800 converter and a 3000 pill in the MSD window switch, that was cutting 1.50 60ft. I ran a paper clip across the 3000 pill side so that it would be on as soon as the car went full throtle. He was complaining about the 60ft so I said this would fix it. He said no it won't work and thought he would be disappointed. The next pass out everything being the same the car went 1.41 60ft with a stock 4L60E and a stock 10 bolt with 3.73 gears. LOL The car went 6.48 with heads and cam and a 125 NX kit. LOL. If you allow the converter to get hit harder be getting a head start with the bottle, it will leave really nasty like. LOL I footbrake my car to 2000 and leave off the bottle. It has hit a best of 1.38 with a 150 shot.

yes lots harder on everything. but, i still do it. 200hp on my stock 00 formy. i hit it at 2k rpms 11.97 @ 118 is my best so far. i added a cutout since. but it was rainy and headwinds were pretty good. did 12.026 @ 119. going to try again on the 31st. http://www.stealthram.com/2000pontiacformula.html dyno numbers came up 442/522 motor numbers were 303/309.

i did a test on my 99 TA i had. auto 3.23 gear. sprayed 150 at three different rpms. here's the results

2500 rpm
60ft - 2.104
1/8 - 8.233 @ 90.86
1/4 - 12.534 @ 115.00

2000 rpm
60ft - 1.979
1/8 - 7.961 @ 92.00
1/4 - 12.212 @ 116.09

1800 rpm
60ft - 1.951
1/8 - 7.875 @ 92.20
1/4 - 12.126 @ 116.11

the next week i got this

1/8 - 7.817 @ 91.55
1/4 - 12.096 @ 115.38

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.......

GueSS Who

This is not a comparison at any rate. Are you on Nittos or something. We are talking about dead hooking. You are spinning for 60ft if you are hitting 150 out of the hole and getting those 60fts.
