Does anyone know or have a chart for NOS jets?

Im looking for a 75 shot, 100 shot

NOS/ Fuel
.040 .021 75 shot ???
.046 .026 100 shot ???

As I look on the internet I find alot of different charts and its starting to piss me off !!!

What brand is it? I'd go to the respective web site to find out. Different companies have different size/hp ratings I believe.

you MUST use the manufacturers rec. jet sizes. If NX, use NX, if NOS, use NOS. Otherwise, the proverbial shit gets fucked up. I have a chart somewhere... just use whatever kit has the same fuel pressue as you do (probably around 40 psi)

The NOS/Holley web site is absolutely horrible.

I am pretty sure it is a Zex wet kit. Kevin will have to verify.

[Joel]

Oh, yeah I think you are correct.

[aliengotpsi]

zex bottle, the rest is an older NOS kit..

As for jets I have a 037 and 022 thats what came with the kit...

I run a base fuel pressure of 43. and lots of boost..

QFT.

You can drill your own if you really know what you are doing.

So, it is a Zex bottle attatched to a NOS wet system?

34/18 40HP
37/22 50HP
39/24 60HP
41/26 70HP
43/28 80HP
46/30 100HP
52/33 125HP
61/38 150HP

Thats for an NOS kit @ about 42-43psi of fuel pressure

EDIT. Wait, that might be for a dry system....

If it was for a dry system it wouldn't have 2 jets.. Looks like a 50 shot alien.

I think NOS has 2 solenoids at different jets....thats why there are 2 numbers for dry sytems as well. I could be wrong.

Just get a NX system, and I can tell you then, lol.

EDIT, nm, thats for a WET system. I was right. YAY ME!

[PSI2HI]

ok 50 is enough for now... does anyone have a purge kit for sale??

according to that it's about 63hp jets.

Kevin, call up NOS and talk to their tech support people, that's what I had to do before, and they will try to tell you not to run over a certain shot on whatever car you're running it on haha.

i agree just take the jets and put it back together, it might leak a little but that would be the least of ur worries
