Ok I am thinking about running a 125 to 150 shot of the juice. But I dont want this to happen.

What steps do I have to take to avoid this.

 

link doesnt work

 

what happend in the vid?

If your wanting your engine to live, get colder plugs, retard the timeing about 4-6*, and make sure u have a good enough fuel system to keep up. I would recomend going to a dyno to fine tune your jeting and bottle pressures.

What motor do you have? Any plans on rebuilding?

 

Fixed link.
I have a 406 with forged pistons stock rods and crank. I have a msd 6al, blaster coil, and wires. Fuel system consists of -8 feed and a -6 return. 255 lph fuel pump. Also intake is a tpis big mouth.

 

#1 Don't use the typical "wet kit" in an intake meant for dry flow only.
#2 Use a race plug better suited to nitrous rather than a street type of spark plug.

 

also dont hit it at low rpms

 

Well here is my plan of attack. TPI nos kit, zex bottle warmer with thermostat, msd digital window switch, and a full throttle switch.

 

dont forget the low fuel pressure saftey switch

 

oh yeah forgot about that one. I think with all that stuff I will have a safe nitrous system.

 

yep thats what i have on both my cars, accept my camaro doesn't have a fpss since it has such low fuel fressure, but i would never run nitrous with out BOTH WOT switch and MSD window switch and i wouldnt recommend spraying anything lower than 3000 or 3500 to be even safer, i spray 3k on the camaro and 3500 on my grand prix, you also need remember about timing and spark plugs, and fuel and the internals if u are stepping up past 125 shot IMO just use it correctly and dont get spray happy and throw 200 shot jets in on a cast bottom end

 

What would you recomend for plugs. Right now I have stock ac delcos in the car. What ever came on a thirdgen with a 350. I also have forged pistons. I was thinking of spraying at 3000 rpms. I only rev. the motor to 5200 rpms.

 

Autolite AR12

 

Also don't try it on a Cobra like that guy did!

 

From what I have seen cobras perform vary well on the spray.

 

NGK's or Autolites seem to work well for nitrous
