Re: Barry grant nitrous works questions

i think i have my old nitrous works jets if you want them. I will have to look for them though in the garage.

I have an nos plate and use generic jets.

As long as you use the same jets from the same company (not NW fuel jet and NX nitrous jet) you are ok.

Re: Barry grant nitrous works questions

I really thank for the reply. Do you happen to know if I get the pills from you what the pill number for each different shot. I lost the card also. It should I just buy another plate and take out the guess work

NOS has the chart on their website. I feel shows safely rich. Uses 43 lbs for baseline. I presume NOS is same as what was posted. Those pretty match up to what i have in my sniper kit just between 49-67 seems to be a gap.

Re: Barry grant nitrous works questions

I forgot to mention its a carb plate a 4150. Im sorry i thought i said that, but i was typing from a cell phone. I was thinking i looked at some nos carb plate kits. i was thinking i could use the same jets from them. just wondering if i should follow the jet guide from their kit and use their jets. If someone could let me know if that would be fine. And if i still can use the jets from 88gta383. Ill post a pic of the plate becuase i read somewhere the amount of holes in the spray bars matter. but that could be for just big hp plate kits.

Re: Barry grant nitrous works questions

You can still use the jets but your spread between the nitrous and fuel jets will be closer for the carbed set-up becuase of the fuel pressure difference.

Looks like there aren't alot of jets that I have that are close together besides the .049, .046 and .043.

Just find an NOS carb jet chart and go to ebay and buy some generic jets. I have used those ebay jets with no issues.
