nitrous express kit wont work need help

[david200095367]

ok i installed a nx kit and it was working fine. the next day i tried it out and it was not working. i have the nx kit installed with a msd rpm activated switch making it turn on at 3k and off at 7k. so i took the wire that goes to the rpm activated switch and grounded it, and tested the solenoids with the engine off, and both the fuel and nitrous were clicking, so i believe they are working. what could be the problem? can the rpm activated switch go bad? i need your help. thanks in advance.

Are you running NOS on a stock engine? What are the specs of your 240? Just curious

[david200095367]

hey sorry for the late repsonse. my car is stock besides a intake and exhaust. i am running 50 shot on my 91' hicas, but i am ready to go up to 75 shot in a little.

How many times have you used it? I wouldn't have the balls to spray all the way up to 7k on a stock engine - doesn't it stop pulling around 5500 RPMs?

[david200095367]

i have used it on 50 shot probably 7 times. i ran it to about 6500 rpm and it seemed fine. mine was pulling up to about 6500.

Here's my stock dyno

[david200095367]

hey bro dont forget mine is a 91' with better cams and also a manual. I am telling you mine does pull to about 6500.

[97ka-t]

Oh I'm sure it does, I was just putting up my dyno for comparison

[david200095367]

yea i haven't dynoed mine yet.
