I have the NOS 5177 dry kit. Well...I had the .32 jets in for as long as I've had my nitrous kit. That's the largest size jets I had. I just took them out and am going to run it unjetted tonight. How smart/dumb is this? Will I go ?

Should I jet one side with the .32 and leave the other unjetted? What size shot would that be? 125hp?

I really need some help on this...I'm going to the track in a few hours.

Thanks guys.

 

uhhhh dont go unjetted.


'tis bad.

 

I just left one side unjetted and one side has the .32 in it....that should be around a 125 shot, right?

 

lets pretend theres a watermain infront of your house.

theres two faucets coming off of them.

if i crack one faucet open, and i rip the pipe off of the watermain on the other side..... whats going to happen?


if you said: its going to pour out the watermain unregulated while the other faucet doesnt do much....... you're right!

 

Nice analogy. But thusly, isn't this the exact scenario I'm trying to complete?

If I run both sides unjetted, then it's comparible to a 160 shot. However, if only one shot is unjetted and the other is regulated, then the water, so to speak, couldn't flow as freely.

 

remember how its a Y fitting?

the other jetted size isnt doing jack... one side open is like both sides open.

at that point, the only limiter is the next restriction down the line.... probly the 'noid.

 

Hm. So all the nitrous would just flow through one side.

 

I ran a dry kit unjetted for over a year and had no issues with it on a cammed, headers LS1 with the stock fuel pump. Not saying its totally safe but I did it and got away with it. Bizarre twist of fate though my nitrous solenoid stuck open on me with a full bottle and emptied the entire bottle into my motor at idle. Needless to say I had to rebuild but it all turned out for the best as I upped the cubes and everything.

 

I run a single nozzle unjetted and dry to boot.

The jet itself is a restriction, I ran all the way through the jets and the next step up was teh size of the orifice in the nozzle... hense no jet. The amount varies with bottle pressure just as it does with a jet in the thing. Figure out the orifice size of your nozzle and look up the flow numbers for a comparable size jet.

 

Dual .038's is what NOS rates 125hp at crank or 106.25 at rw. You can run different jets of a few size diff, but running one at .032 and one open is like whats said above. N2O is going to take the path of least resistance. The noid has an single orifice of .076 and nozzle has a orifice of about .087 so you'll more than likely get the full 150 rw hp out the one side and some more out the .032. Playing with fire without tuning maybe?

Oh yea, a .043 and an .042 is 147.5 hp at crank and 125.37 ar rear wheels, remember these are mathmatical numbers from a set formula and doesn't take all the diff varibles into account, tune is best.
