A couple of nitrous questions?

[fastimes69]

I'm running an NOS (05115-2) stage 2 kit on my coupe and am currently running a 175 shot.What all is needed to upgrade this kit to a big shot or to run like a 200 or 250 shot.Has anyone ever upgraded this particular kit? My cousin just got a Nitrous Express wet kit that's adjustable from 35 to 150. Is it possible to run a 175 shot and if so what are the jet sizes? I figure if I can do it with an NOS dry shot, someone must know how to get a 175 shot for the wet N.Express kit. Any info is appreciated, thanks

go to the nos webpage on their tech section there is scads of info there on jetting.

as far as the NX kit is concerned the book that came with his kit has all of the jet sizes listed.

the problem in both situations is lack of an adequate fuel system to handle more nitrous without leaning out the mixture excessively. in both cases just contact the manufacturer for their recommendations on upgrading the fuel system and you should be golden.

FYI just tossing in the next bigger jet is not a good idea = melted motor.

The thing is we have upgraded our fuel systems, I run 24 #ers with the pusher that comes with the kit and my cousin has a pusher with a 190 in tank.

Then really all you need to do is call up the respective manufacturer and ask for their tech guy. They can direct you as to what their solenoids will flow etc. I sell NX systems and the solenoids that come with them will definitely out flow the 150 pills that come with the kits. The nozzle and its atomization and freeze up properties may come into play however. I am not super familiar with th NOS nozzles but I know that NX sell a SHO nozzle that is good up to 400 hp so that may be the next step for both of you really. Upgrading the nozzle will allow you to use whatever you are adding by way of squeeze. Keep in mine that fuel alone wont protect you. At the levels you are wanting to run the cyl. pressures and detonation become critical. An aftermarket ignition and good head gaskets and head studs may be required, maybe even o ringed heads and block. the best advice will come from the manufacturer of the kit. Hope this helps
