I keep hearing dont spray under 3000 rpms. I have a Vig 4000 stall. Would it be ok to spray out of the hole with this. Since I will be above 3000 rpms. I will be spraying a 100 shot for now and closer to winter I am going to a 150 shot. I also have a stock bottom end.

 

All you'll need to get is a window switch, it only allows the nitrous to come on in a specified rpm range. You adjust this through the use of pills, you just put in a 3k pill and it won't let you spray until you hit 3k rpms .

 

Take this for what its worth I dont even recomend you try it but its what works for me. I dont use a window switch I hit it off the line with a 3k stall did the same with the stock stall to. I pull. 1.79 60ft on motor and 1.63 on a 150 shot.

 

I don't have a window switch either. I launch off my 3,600 stall. Best 60ft. so far of 1.55.

 

It doesnt seem to me that a 3000 window switch would serve much purpose if I am running a stall bigger than 3000

 

Can someone correct me if I am wrong?

 

I wish I had one when my car dont want to shift it hits the revlimiter (MSD) I would like to have it cut off the juice before it but I have never had a problem with it like that. and it hits the revlimiter alot

 

Sounds like your tranny is going bad

 

Nope I have a case of the OBD1 blues 3k stall 1.63 60ft = no shift for me but I am working on that. I just ran a 02 Z06 he pulled me about a 1/2 car out of the whole and I ran out of juice. on the top end. and we stayed the same.that was on the 2nd run the first run I had juice and it looked like John Force doing a burn out The trans works flawless on the street

 

My convertor is sized to flash to 5K rpm under an 800ft-lb hit. Basically, stall it up to 2,500 on the foot brake and floor it when the lights drop. The 800ft-lb will have it at 5K rpm in millseconds! No problems. No lower limit on the RPM. Then just hold on..... .
