newbie needs help from nos pros

Hi guys , Sean here from Cape Town , South Africa. I have recently gone the route of a wet nos setup. I am really new to this and I do not even know If I have put the foggers in the correct place. I have them about a half inch into the stacks. I have removed the secondary butterflies and have .18 nos & .20 fuel in each fogger. These jets are for a 48 shot. I am using race fuel too. The problem is that when I push the button it seems like the motor wants to die. It feels like the bike misfires badly. Is this because the spray is not allowing the normal air to enter the stacks. Your help please. I AM PULLING MY HAIR OUT...LOL THANKS

Could be many things. But sounds like maybe it's getting flooded with fuel. How big of nitrous bottle do you have? How do you have it mounted? Do you have a bottle heater? What PSI you keeping it at?

It should pulll very strong and yes nozzles' are ok there. Thats where mine are.
Are you using a'WOT switch?
Are you using a clutch perch switch?
Are you only trying WOT ?
Have you upraded your fuel pump?
Is your bottle facing down or up?

The'answers should be yes, yes , yes, yes and down assuming you have no siphon tube.

Hope this helps. Good luck..

What are you using the bike for ? Drag , LSR or road?

Hi , sorry about the delay as we have an 8 hour time difference. I have a 2 pound bottle that has been mounted in the tail of the 12. Got it at the correct angle and the right direction as shown in numerous diagrams....siphon facing the direction to where the liquid will pool under acceleration. Bottle is at 900psi and yes the bottle heater is ,me ,with a gas torch ....like the street outlaws do....lol. I time the amount of direct heat for 2 minutes ...well according to the lazer thermometer the difference between the before measurement and after is only about 2-3 degrees...celsius .
Another question I have is ...does it matter how thick the lines from the solenoids are. All my lines I had made up with the ptfe stainless braided ones right from the bottle to solenoid to the foggers ...4-5 mm inside diameter lines. Cost a bloody fortune...lol. Read some horror stories about backfires and nylon lines melting in airbox, I thought prevention is better than cure. Could the diameter of these lines cause too much fuel or is the flow rate strictly controlled by the jet no matter what diameter of feed line is used. Sorry about all the questions but I value your guys opinions and experience. You have been doing this a lot longer than I have. I will take some pics and post when I get a chance tonight.

Dave , I went onto the Holley Performance site and found the exact fuel pump that they sell with their kits.....this pump is a high flow /low pressure ,rated at 18 gallons per hour and the pressure is only 5.5 psi . They saw this pump can support up to 200 HP......does this sound right. I bought this system second hand from the US on Ebay. It was on a ZX 14.
