Default Online jetting calculators?

quick question gang.

when using one of the online jetting calculator (wet) is it v8 specific?

example:
calculator shows that a .042 nitrous jet needs a .024 fuel for a 67h shot.

is it the same for all apps?
or just v8?
looking for jetting for a 6'er. (up to 125 wheel)

thanks

the fuel jet is based on fuel pressure.

the theoretical mixtures are the same for anything, Its just a ratio of nitrous (in estimated HP) and fuel.

The only difference is that smaller engines are generally arent able to be jetted as high as bigger engines, because they physically cant ingest as much nitrous/ fuel. they factor the number of cylinders for the shot.. I/E a 150 shot in a V8 is a 18.75 HP shot per cylinder, where as in a 4 cylinder it would be 37.5 per cylinder. theoreticly to put the same cylinder pressures on the 4 cylinder that a 150 shot would put on a V8 would be a 75 shot. Hope I didnt just confuse you more.

ok, so the online calcs do use a v8 based script to figure the shots.


anybody know of a calculator for a v6 model?
looking for jetting for a 75 & 100 wheel hp (using the nos fogger).

i called NOS/holley and they wouldnt give me or just didnt know the jet settings for the 100....
and the jetting for the 75 was flywheel. (36/24)
