im gonna install a n.o.s 50 shot dry. i searched archives and just wanted other opinions. should i upgrade the fuel pump?retard the timing? i know i need colder plugs. what else would you suggest? go ahead flame away! what do you think this might do for my 1/4 mile times? TIA

 

nice sig

 

50 shot just leave everything stock, you'll be fine. You can get a step colder plug and always run premium grade gas. Just make sure you install it correctly and use the fuel pressure hobb switch with the kit.

 

Get a purge kit so that you keep the nitrous pressure off of your noid seals when you aren't using it. And get colder plugs.

 

purge kit will not aleaviate pressure on the primary nitrous solinoid, the solinoids are designed to withstand the pressure from the bottle. IMO the purge valve is good for checking to see if there is nitrous still left in the bottle.

 

1. Before you spray it is common practice to purge out the old nitrous until you see a nice white cloud. After you make your run, close the bottle, and purge the nitrous out of the line. This gets rid of the pressure on the seals.
2. I'm not talking about the solenoid. The solenoid is made of metal it won't deform because of the 100 psi coming from the nitrous. I am talking about the little, piece-of-**** rubber seals that NOS uses in their super powershot solenoids. When exposed to high temperatures the rubber will become supple, and a nice nipple will form on the seal effectively blocking about half of your nitrous. I'd show you a picture of the 5 of mine that are shot to ****, but I had to send them to NOS so that they would send me stronger seals for free. In their larger noids NOS uses teflon seals and I believe the ones that I was sent are made of cadnium, but I could be wrong.
If you want to know if you have nitrous left, weigh the bottle.

 

thanks for the info guys!
