Im running a .065 n and a .057 fuel on a mild 350 sbc in a 59 chevy pickup. So far its gone 13.75 on motor and 12.28 on spray. Do you think if I flip the jets I could hit a 11.99?
thank
P.S. or hit the track with my crank?

It looks like you have already flipped your jets. If your plugs look okay, you may be able to take some more fuel out. With a 65 jet, you are getting close to being maxed out with that plate. You may be able to jet up a few more sizes.

Then Flip it. It needs a larger N2O jet then fuel jet. .065 N & 057F. It will pick up et, if you run it like this. What fuel pressure are you at??

Is that a flowing Pressure or a static pressure? That pump runs spray and Motor, Correct? If so, I would get a Stand alone pump for the spray.

Yes it runs both it has a little over 6 at idle so those numbers were kind of a guess. its a holley pump. I was hoping at such a low h.p. level I could get away with it.

You might be able to get away with it. You have made it this far. Yes, Flip that tune and see what it will do.

I figured you would have been in the 110mph range. Might want to start looking over and checking a few things.

It only gets more addicting from here.......lol
