I will be going to the track next week and thinking about changing my jets out, but don't know the n20 or fuel jet numbers, if someone could help with the following jets

175 shot
200 shot
225 shot
250 shot


thanks in advance

 

250 shot should be 88.

 

Jetting should be close:

175 n-68 f-36
200 n-72 f-38
225 n-76 f-40
250 n-80 f-42

These are for bottle pressure at 1000 and fuel at 58 or so... I would be a little worried using a single nozzle. That's a lot of fuel to deal with.

 

great, thanks for the help. Now I just need to decide if I am going to want to gamble with a 250 shot or not.

 

I got this right from NX

200= 78n 44f

225= 82n 46f

250= 88n 46f

Fuel is the same for 225 and 250.

These are not the correct jettings for a NX single nozzle system. Our systems are designed to be ran at 1050psi bottle pressure. Here is the jetting you need;
HP N2O Fuel
175 73 41
200 78 44
225 82 44 or 46 depending on your tuning preference
250 88 46

Also, if you don't already have the SHO hose you will definately need it to get these hp numbers out of the system. Otherwise you probably won't gain much over 165-170hp.
