seems like a 100 shot, but on the rich side.

prolly playing it safe.. im not really sure.

62/33 is a 150 shot.

57/31 is a 125

52/28 is a 100

is the 125 shot really the 57/31 jets? i called Nitro Dave's to get the 125 shot jets and they sent me the 57/33 jets. (the 33 jet was already in the kit that i bought from them, though)
i've been meaning to call them and ask, i just haven't gotten around to it.

I've read in the older posts that NX changed their jetting charts on more than one occasion. I personally run 57/33 for my "125 shot".

chris mac

ok, thanks.

There is no absolute correct when it comes to jetting. It's a rough estimate that needs to be tuned.

52/33 should be a pretty rich 100 hp.

I will say my car, tuned to 13.0:1 A/F needed the 33 jet for fuel in order to make a safe air/fuel ratio (around 12:1)

That's a rich 100. I run 52/31 for the 100 and I'm a bit on the rich side.

If this were used on a vehicle with less fuel pressure than an LS1 it would probably be closer to ideal.

I run 52/31 on the 35th for 100 shot.better to be rich than lean.hook a f/p gauge so you can see when you hit the giggle.should drop from 61 to 51-53psi.when you comin out to the track?
