I have a Vic Jr. manifold on one of my cars and want to use a NOS Cheater plate as a first stage and a nozzle as a second stage. What I have found is that the nozzle does not hit hard enough. My questions is "has anyone used one of these plates with a high fuel pressure system?" I really don't want to add a seperate fuel system. Seems like I have enough crap in the engine bay already. Thanks.

Carlos,
You should be able to run that plate with high pressure. You will need to call NOS tech and get the right jetting. Make sure to test fire the plate on that intake and make sure it flows correctly.

I sent them an e-mail about this. I had a friend (local NOS dealer) inquire by phone about this same question recently with the NOS techs. Their response was it will work, but to just get a fuel cell and pump and not worry about it. Hopefully, I'll draw a different tech. LOL's.

175hp - 73N 35-39 @ 50psi
200hp - 82N 39-45 @ 50psi
250hp - 93N 40-45 @ 50psi

The larger jet listed will produce a 5.0:1 nitrous/fuel ratio and the smaller one should yeild a ratio of approx. 6.0:1

This is taken from an old NOS tech bulletin which I'm sure Hollry has lost since they moved everything to Bowling Green. it should get you close. But I do agree with what they said about running lower pressure it would be easier to tune. You should be able to run a regulator to bring the fuel pressure down to around 6psi.

If you need jettings for a diffrent pressure let me know the chart goes from 4-90 psi

Thanks for the info. Would you happen to have 100 and 150 shot settings at 58psi?

The old charts didn't go that low but these should get you in the ball park

47N 22-24F @ 60psi for 100
63N 25-28F @ 60psi for 150

Thanks again. Those numbers are very similar to the jettings for nozzles.
