What size jets do I need to spray a 150 shot with a 5177 NOS kit?

If I'm not mistaking, I was told that without jets it only sprays a 140 shot, thats all the silenoids (sp) will spray.....

Yeap, I do that . To shoot 150 you would have to replace the twin noids with a bigger one.

Dual .043's are the hp rating at the crank according to the way NOS rates the jets. I believe that no jets is equal to 180hp shot. But, what we need to remember is the stock injectors are the limiting factor. If you have the 28lb injectors you can go 150hp but do auto tap or dyno to make sure your not lean. That is why some of the guys only get so much out of the no jet thing: not enough fuel, running lean. I have more info on the 5177 kit, including a way to get past the 180hp limit without changing solenoids. Got to go for now though, will check back later.

28.8 injectors are sufficient for anything around 500 rwhp at 100%.
I'm around 490 rwhp on juice yet my injectors are at 91%. 12.3 WOT/AFR ( I could actually lean a little but "safety" compells me not to do so)
A when I say shooting 150, I mean 150 rwhp, not fwhp.
(That is for ricers )

I agree.
