help need to know 150hp shot jet size

[wenlipai]

hi, i'd like to know what will be the jet size for 125 ~ 150 shot hp ? i was thinking of 55n - 33f the brand of my nitrous is Holley, right now i'm running 75 shot (46n 26f) but can't feel anything maybe due to my supercharger 12psi (vortech), my fuel press. is 4 bar so maybe is around 58psi, and i have heater 1050psi, and right now running like 11.8 ~ 12 AFR , so any advice? thanks

PD: i'm using wet nitrous

This is the calculator I use.

I'm running .061N, the chart calls for .033F, but I run .036F. .061N is good for up to 142rwhp.

a 46/26 is a 100 shot usually.

58/32 should get you right about 150. Good luck.

Actually, it depends on what kind of horsepower rating you're using. If you're going for a true 150 whp, then your nitrous jet should be into 60s and fuel in upper 40s.

If you don't know the stock fuel pressure, then read the stickied thread.
