I installed my wet kit today I am running NX kit with a NOS plate. I don't have any charts to go off of with the TBI 305. I talked to a few of you on here, a few months back when I was thinking of putting N20 on the Camaro. I am looking to run 50/75/100/125. I have replaced the stock pump with a gm unit. I also put in a window switch. I will try to get some pics of it up tomorrow. It's kinda stealthy.

 

I don't know if you've found the sizes yet but when I needed the sizes for the cheater kit I just called NOS and spoke to a rep.

 

I just got on NX website and went with there Jet sizes. I had to order some NOS jets.

 

I'll toss these in here in case someone hits this thread while searching, so they can find an answer, This is the jetting that Holley gave me for TBI.

100 -- 47N20/36Fuel
125 -- 52N2O/39Fuel
140 -- 65N2O/42Fuel

I am currently running 55n2o/40fuel, my fuel pressure is a bit higher than stock, but i was VERY (I pegged the WB out at 10:1) rich on the dyno, I figure that is holley's overly rich conservative recomendation, along with my higher than stock FP.

 

How much RWHP did you pick up with those jets?

 

I picked up 84 rwhp and 170rwtq with those jets. But i was overly rich, and it was cold out (I have no bottle heater)

 

DO NOT RUN THE NX JETS WITH THE CHEATER PLATE!!!!!!!!!!! You are going to hurt something!!!!! trust me on this one. if you are running an nx system with a nos plate you need to run the nos jet patterns!!!!!!!!!!!!!!!!!!!!!!!!

 

I don't see what the problem would be? It's just more RWHP. If everything is tuned right it shouldn't be any problem. The plate is going to be able to flow the extra N20 and fuel.

 

Each company flows there own plates for there own jetting.Each companys patterns will be different.Its a bad idea to cross bread jetting.
If you are running a NOS plate run NOS jetting.
