nitrous help please...

[trav_19]

well i got my kit all together and i have had some small issues haha ordered jets online from some small company said it was a 100 hp set got them and they had no sizes marked in them so i wouldn't use them ...i ordered nos stainless steel jets and was told that a .059 and a .042 would give mea 100 hp but i want to make sure before i run it sounds big to me...anyone know how to calculate them?? its a fuel injected car so the nitrous gets the bigger jet right? because the smaller jets from my friends kit were installed with the fuel being the larger one and the nitrous being smaller...so that is backwards right?? i want to put in my new jets and make sure they are done right and know what size i auctually have thanks a lot guys

61 and 38 are 150 or so with the bigger being the n2o jet. I had a list for what jets for what hp on the computer but lost it.

Well hes askin about the fuel jet so im pretty sure that makes it wet.

Assuming this is for an NOS 5115 dry kit:

59 fuel/ 42 NOS = 75 HP and 42 fuel/ 59 NOS = 125 HP

What injectors do you have, as that changes the jetting?

You WILL need a 255 high pressure pump.

its a wet kit and right now its stock injectors and pump i would assume is OE as well ...not putting any money into either of them however as they will both be useless to me in a few months once my carb engine is done....i just want to have some fun with the stocker engine until then and i figured a 100 shot will buy me some time lol as a 125 or larger would probley pop the engine quickly since it has a 178k on it lol

NX. These settings are for 40-45psi fuel pressure at WOT only. If a person wants to use this jetting they have to run this pressure at WOT, otherwise the A/F will be wrong. Also, this jetting IS FOR A SINGLE SHARK NOZZLE ONLY.
HP N2O Fuel
35 31 18
50 35 20
75 41 24
100 52 31
125 57 35
150 62 38
175 73 41
200 78 46
225 82 46
250 88 48

so im guessing if i put these in with the ;arger one in the nitrous its going to be like a 133hp or something...what if i use the larger one in fuel and the smaller one in the nitrous...would it work at all?

 

[slvrbullit302]

here is a site that has some jetting info for NOS 5115 kit.

I found there info to be pretty good and close to the power numbers.
