i am looking for a chart that shows what combinating of jets to get certin hp levels. the car is carburated. im looking for a 150,175,200,225,250 shot combinations. the calculator says im running a 230 shot which is wrong.

here are jetting sizes for NOS "big shot" maybe it helps kit # 2117

HP n20 / fuel
150 hp -------- --38 / 24
200 hp -----------45 / 30
250 hp ----------- 55 / 32
275 hp -----------120 / 116

a #38 is .038" etc.

those seem wrong. the kit i have says a 71nitrous and a 67fuel for a 150 shot. i want a 200 shot.

are you talking about a carburated kit?

nitrous_bob

oh no, thats a big shot 5.0 plate

i missed that "carb" part

check the tech manual for the carb kit on http://www.holley.comthen link to NOS , then find the kit thats like yours

look at the pdf file, it will have jetting on there , i have only FI stuff here

250------------93 / 102

thats looks better.. Thanks!!

no probs.....if you can't find a specific jet, going bigger on fuel and smaller nitrous is fine it will run a bit phatter

if you know FOR SURE your not near lean, you can tweak it up on the nitrous or down on the fuel

sometimes unless you order...the speed shop will have jets a little off from exactly what your loking for
