How much to run? i have a 94 z28 with the NOS dry kit on it. right now i only have a .41 pill in it. probally like a 50 shot.
But my kit did not come with the fuel pump, so i have a new ac delco pump.
im just wondering if the z28 fuel pump as enough pressure to up my nitrous to lets say my .64 pill?
i havent changed the plugs yet or retard the timing. what to do next? i got beat by an LS1 ....haha

Don't let them bother you about a 50 shot. Many people are buying heads for 2k + for less HP. I am running a 50 dry right now & it is a nice kick in the pants on the street at 3k rpm. Of course I want to do more but I am leaning out a little too much at higher HP levels. I will soon remedy that....

TR6 pluggs gapped at 34 - 35 on 92 or higher octane fuel and you can spray a 150 wet, or 100 dry alllllll day long, my 96' Z28 lasted 116,000 miles with that set up.. Good luck.

Come on now 50 shot? Better off with 75 to shot! What just saying when you do shoot a 50 you will want more. I say just upgrade your fuel pump and plug and shoot at 100-125...you'll be fine!
Keep in mind,That the inline pump that comes from NOS is nothing but a band aid.If you want to do it right and stay safe put a intank walboro in there.Also You will need to start looking into fuel injectors depending on how large of a shot you go with.The LT1s only come with 24lb injectors.If you wanted to save your self the hassle of injectors and tuning I would convert to a wet system.

Isn't the idea of the LT1 dry kit to use the stock injectors and spike the fuel pressure to trick injectors into a larger size. If so, I would compare the Delco pump specs to the NOS pump and see if it is capable of supporting your needs. If I remember correctly, the dry kit on an LS1 with the NOS pump can support a 150hp shot. Maybe call NOS tech (good luck) and find out about pump and pressure needed.
The LT1 Dry kit does spike pressure to around 80PSI on the injectors. The stock fuel pump can not maintain this high pressure. I highly recommend putting a walbro in-tank pump or the in-line NOS pump on before going to the 64 jet. The in-line NOS pump is nothing more than a 255 high pressure walbro pump and is very functional.
