Just wondering if anyone has ever added a nano or pusher system without rejetting to see if rejetting is actually needed. I run a zex 150 shot on my ls1 vette and it seems to already run really rich with the zex recommended jetting. Thanks ahead for any help.

I haven't put mine on yet, but I don't think not jetting down is such a good idea, do you?

your safest bet would be to log it with a wideband.

if you do not re-jet you WILL be lean. try it with a wideband but for the 20$ it is for jet(s) why not?

edit- or just ditch the zex system and you'll gain power.

Thanks guys for the info. The only reason that im asking is because I love the way that my car runs on the 150 shot and dont want to lose any power by going down to the 125 shot although nano say's that it will actually make 150 h.p. with the pusher system installed. But Im just not sure if it will and was hoping that someone has done some dyno runs to back up what nano is claiming. Thanks again for all the help.

I didn't change my jetting with the NANO and my air/fuel is the same 11.5 or so on the wideband as it is with a full bottle at 1050psi. My ETs didn't change either. I was hoping for a bit ot ET reduction. But, NANO's value to me is the elimination of the bottle heater and 1050 psi each time I open the bottle for consistancy.

Odds are you will need to rejet the system. You will still make the same HP if not more. Here is a tech article to help you understand how it works.

Thanks for the info. What nitrous kit are you running? Does the pressure drop as soon as you activate the system at wot?

Thanks Dave, great info. I have a zex kit and I have it set up with a 150 shot but being that zex jetting is so rich I thought that I could just add the nano kit and not have to change a thing. Do you think that My kit can handle leaving the 150 pill on the nitrous side and upping the fuel side by 20% or will it be to much for my kit to handle? I looked into other nitrous kits but when I was told if I wasnt planning on spraying any more then 150 shot that it would be a waste of money to change out my zex kit for another brand which I appreciated the company being totally honest with me.

The Zex system will flow more than the 150. Uping the fuel jet will be fine. However you will see a hp gain compared to what the system does now.

See I was told that the little noids in the purple box wouldnt flow more then a 150 shot. So I could keep the 150 pill in and just up the fuel by 20% and add the nano system? Will this increase the shot from 150 to 180h.p hit being that it claims to produce a 20% more h.p. gain ? I was always under the impression that the only reason why it made the extra power is because the pressure. Do you think that my stock c5 can handle the hit if I just up the fuel side. Do you have any nano systems in stock? I do run tr6's. Also what do you recommend the plugs to be gapped at for this size of a shot? Thanks for all your help.

You were informed wrong. Zex does not advertise the system to flow more than that so many do not know. The system should max flow 175.00 just like it sits. Yes we keep Nano systems in stock.

gap the TR6s to 35

anyone else spray without rejetting?

I have an NX dual-nozzle Gemini Twin kit at 150 HP. Actually, I'm not sure about pressure drop upon activation. I have my gauge right on the valve. But, with NANO it it 1050 before and after the run.

if you always run a fresh bottle with constant pressure on a 100-150 shot - why would you need to rejet with a nano?

During the run the pressure will drop, even bigger drop the bigger the shot. So since the pressure doesn't drop you are getting more nitrous flowing into the motor during the run. That's why you need to use a bigger fuel jet so it doesn't lean out on the big end. For those with a standalone fuel system you can also adjust the fuel pressure up to compensate.

I just dont see a crazy drop in pressure during a run....
