OK this is kinda how i heard it.It`s a flow thing say if you have a Djet wich i see as a hi speed the flow would go through the sloted side and out the smooth end.As for C`s it gonna go the other way and i see them running on the small side like for intermeadate or small carbs.One of the GOD`s of omc would have a more detailed answer!!!!!Have you been out yet there freddy?I took the twisted blue trucker out last weekend WOW!! hard to handle and goes like hell. let me know hows it going for ya Happy easter

[Fast Fred]

still cold hear, the water is about 38-40 deg, the fishin dudes around hear say
that gives ya about 20mins to live if ya get tossed

your right it's a flow thing on the jets, got any .130 thou' main nozzles, i needs some

Why can't you just shoot in the mix into the intake (front ) of the carbs? i saw an OMC factory setup (nitrous) on a 75 horse stock SPORT E back in 1976 , it was 30 horse gain , really worked well.

[Fast Fred]

you can dust it in the airbox, but on a big hit it tends to freeze the reeds open
and the cyl drops,

Are you adding more fuel at the same time you add the N.O.?

ya, if you don't it will just blowup as soon as the NOS hits. the nozzle smashes
the fuel and the NOS together, atomizes it.
