[Shotimes] N20 jetting question

[Tom W]

Try .041 N & .029 F. If it works OK, you can try leaning it out with an
.030 fuel jet to make a little more power. You want to make sure that
you have copper core plugs that are 1 or 2 ranges cooler than stock
gapped around .035.  The ZEX Mustang jetting will be real lean in a SHO
and may cause damage. NOS and ZEX will make the same power for a given
nitrous jet size, but the fuel jets are different due to differences in
the way they pressurize the FPR. (ZEX has an "expansion chamber" in the
controller box. Traction will be an issue at this power level.
